    On the 1985-1995 Chrysler LeBaron, the Auto Shutdown (ASD) relay powers the ignition coil, fuel injectors, and (via the fuel-pump relay) the fuel pump. When the ASD relay fails, contacts wear, or its connector corrodes, the engine cranks but gets no spark and no fuel and will not start; failure can also be intermittent, causing the car to die while driving and then restart later. On many LeBarons the relay sits on the driver's-side fender/strut tower. Because the same no-start symptom can come from the logic/power module or the pickup, the relay should be swapped or bench-tested to confirm.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Engine cranks but won't start — no spark and no injector pulse
    • Intermittent stalling while driving, restarts after a wait
    • No buzz/prime from the fuel pump at key-on
    • No power to the ignition coil or injectors when cranking

    How to Fix

    Test the ASD relay (listen for the brief click at key-on, verify it powers the coil/injector bus) and substitute a known-good relay; replace it if it fails to energize the coil/injector circuit. Clean and repair the relay connector and check for blown fuses and the PCM ground that controls the relay. Confirm fuel-pump and coil power return after replacement.

    On the 1985-1995 Chrysler LeBaron, the distributor pickup is a three-wire Hall-effect sensor that tells the engine computer the engine is turning so it can fire spark and injectors. These pickups are prone to heat-related, intermittent failure: the car runs fine cold but suddenly stalls once the engine bay heats up, then restarts after it cools (heat-soak). The Hall sensor can fail without setting a code, and because the computer sees no engine-rotation signal, it cuts fuel and spark entirely. On the 3.0L, an intermittent no-spark can also come from the coil or ignition module, so the pickup must be confirmed with a scope/voltage test.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Engine stalls suddenly after warming up
    • Restarts only after sitting and cooling down
    • Crank-no-start with no spark when hot
    • Intermittent stalling that worsens in hot weather
    • No fault code stored despite the stall

    How to Fix

    Verify the pickup's 8V supply, ground, and switching 0–5V signal while cranking (a scope best catches heat-related dropout). Replace the distributor pickup/Hall sensor (or the distributor assembly) if the signal drops out when hot. Inspect the wiring and connector for heat damage. On the 3.0L also test the coil and ignition control module before condemning the pickup.

    On the 1985-1995 Chrysler LeBaron, early LeBarons use a two-box system (separate logic module in the kick panel and power module near the battery); 1988+ cars use the combined SMEC, and later cars the SBEC. The power-module/driver section is a known weak point: heat and vibration crack solder joints and fail the injector/ignition drivers, producing intermittent stalling, no-spark/no-fuel no-starts, or a car that runs poorly and drops into limp-in. Fault codes (read by cycling the key on-off-on) help point at it, but the module can fail without a clean code. The logic module also enters limp-in and reduces performance when it loses key sensor data.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Intermittent stalling, sometimes restarts after cooling
    • Crank-no-start with no spark or no injector pulse
    • Reduced power / limp-in behavior
    • Erratic or no charging voltage (early power module)
    • Fault codes pointing to driver circuits or no-start

    How to Fix

    Pull stored fault codes via the key-on/off flash-code method to confirm a controller or driver fault, then replace the failed module (logic module, power module, SMEC, or SBEC) with a known-good or remanufactured unit and ensure clean grounds and battery voltage. Repair corroded connectors. Verify charging-system voltage, since the power module also regulates the alternator field and is stressed by a bad alternator/battery.

    On the 1985-1995 Chrysler LeBaron, all LeBaron engines are belt-driven overhead-cam designs with a rubber timing belt that has a finite service life (roughly 60,000 miles). The Chrysler 2.2L/2.5L four-cylinder engines are non-interference designs, so a snapped or skipped belt leaves the car stranded but does not bend valves. The belts age, harden, and can skip a tooth or shred, causing a sudden stall/no-start or rough running. The Mitsubishi-sourced 3.0L V6 is an interference engine and far less forgiving — belt neglect there risks valve-to-piston contact and bent valves. Because these cars are now decades old, many run on original or badly overdue belts, making this a leading cause of roadside breakdowns.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Sudden engine stall with no restart
    • Cranks but won't start
    • Sluggish acceleration / poor performance after belt skip
    • Rattling or slapping noise from front of engine
    • Rough running after the belt jumps a tooth

    How to Fix

    Replace the timing belt on schedule (about every 60,000 miles), and replace the water pump, tensioner, and idler pulleys at the same time since they sit behind the belt. Verify correct belt tension and that all cam/intermediate/crank timing marks align. If the belt has already skipped, re-time the engine; on the interference 3.0L V6, inspect for bent valves before returning to service.

    Typical repair cost:$250 - $750

    On the 1985-1992 Chrysler LeBaron, the turbocharged LeBarons (Garrett T3-based Turbo I and the higher-boost Turbo II) suffer turbo center-bearing and oil-seal wear from oil starvation at cold start and shutdown, and from coking when the engine is shut off hot without a cool-down. Worn seals let engine oil pass into the intake or exhaust, causing blue smoke (especially on startup or boost), oil consumption, and eventually a frozen or noisy turbo. The small-frame T3 is prone to burnt oil cutting a groove in the turbine shaft so the seals can no longer hold oil. Lack of oil changes and hard acceleration on a cold engine accelerate the failure.

    Common Symptoms

    • Blue/gray smoke from the exhaust, worst on startup or under boost
    • Excessive oil consumption with no external leak
    • Whining, whistling, or grinding noise from the turbo
    • Loss of boost / sluggish acceleration
    • Oil film inside the intake hose or intercooler piping

    How to Fix

    Replace or rebuild the turbocharger (CHRA/cartridge) with new bearings and seals; on the T3, install a wear sleeve if the shaft is grooved. Address the root causes: change oil on a strict interval with a quality oil, allow the engine to idle ~30–60 seconds before shutdown after hard driving, and avoid full boost until oil is warm. Inspect and clean the turbo oil feed/drain lines, which can clog with coked oil and starve the bearing.

    On the 1989-1995 Chrysler LeBaron, leBaron overheating is common and one trap is unique to these cars: in 1989 the 2.2/2.5 switched to a counter-rotating (reverse-rotation) water pump driven off the back side of the timing/accessory belt, whereas 1980–1988 used a clockwise pump. Installing the wrong-rotation pump (or a generic replacement) pushes coolant the wrong way and the engine overheats even though the pump looks correct. Combined with the small radiators, electric-fan failures, and tired thermostats on these aging cars, owners report boiling coolant, rising temp gauge, and on turbo cars heat-soak that can crack a head or blow the gasket. Always match the pump to the engine's rotation.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Temperature gauge climbing, coolant boiling/overflow
    • Overheats after recent water-pump replacement (wrong-rotation pump)
    • Cooling fan not running
    • Overheats at idle/in traffic but cools at speed
    • Coolant loss and sweet smell

    How to Fix

    When replacing the water pump on a 1989+ engine, confirm it is the correct counter-rotating (reverse) pump for that year — do not fit an early clockwise pump. Then service the rest of the cooling system that commonly fails on these cars: thermostat, radiator (recore/replace if clogged), electric cooling-fan motor and fan relay/temp switch, hoses, and a proper coolant fill/bleed. On turbo cars, verify the fan operates to prevent post-shutdown heat-soak.

    On the 1985-1995 Chrysler LeBaron, the two-prong engine coolant temperature (ECT) sensor at the thermostat housing feeds temperature data to the engine computer for fuel mixture and to the cooling-fan and gauge circuits. When it fails or its connector corrodes, the computer mis-fuels the engine: the car runs rough or floods when warm, stalls once hot, and is hard to restart until it cools (a classic heat-soak no/poor-start). The temperature gauge can read erratically or peg, and the electric cooling fan may not turn on, leading to overheating. Note this is the computer's ECT sensor, distinct from the dash gauge sending unit.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Stalls or runs rough only after the engine is fully warm
    • Hard to restart when hot, fine again after cooling
    • Erratic or pegged temperature gauge
    • Cooling fan doesn't come on / intermittent overheating
    • Poor fuel economy and black smoke (over-rich when cold-signal stuck)

    How to Fix

    Test the ECT sensor's resistance cold and hot against spec and inspect/repair the connector for corrosion; replace the sensor if out of range (Mopar coolant temperature sensor for the 2.2/2.5/3.0). Verify the cooling fan commands on and the gauge tracks after replacement. Rule out air in the cooling system and a stuck thermostat, which mimic an erratic gauge.

    On the 1985-1995 Chrysler LeBaron, chrysler's throttle-body and MPI fuel-injection LeBarons use an Automatic Idle Speed (AIS) motor (idle air control) that meters air around the closed throttle to keep the engine idling and to catch the idle when the A/C compressor cycles or when the throttle snaps shut. The AIS pintle and its passage carbon up, and the motor itself wears out, causing a rough or hunting idle, idle that surges up and down, stalling when coming to a stop or when the A/C kicks on, and sometimes a high idle that won't come down. The symptoms overlap with vacuum leaks, so the intake and vacuum lines must be checked first.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Rough or unstable idle, sometimes stalling at stops
    • Idle surges/hunts up and down
    • Engine stalls when A/C compressor engages
    • High idle that won't return to normal
    • Stall when throttle is quickly released

    How to Fix

    Clean the AIS motor pintle and the air passage in the throttle body with throttle-body cleaner; if cleaning doesn't restore stable idle, replace the AIS motor. Confirm there are no intake/vacuum leaks (a common cause of the same symptoms) and that the throttle position sensor reads correctly before condemning the AIS. After replacement, let the system relearn idle.

    On the 1985-1995 Chrysler LeBaron, the heater/AC blower resistor block that controls the lower fan speeds is a common failure on these cars. When it burns out, the low and medium fan settings stop working and the blower runs only on High (which bypasses the resistor). The resistor typically overheats and fails because an aging, current-hungry blower motor draws too much current through it, so a resistor that's replaced alone often fails again if the worn motor isn't addressed. On the LeBaron the blower/resistor is buried under the dash/behind the glovebox, making access tight.

    This issue also affects: Jeep Wrangler

    Common Symptoms

    • Blower only works on the High setting
    • Low/medium fan speeds dead
    • No airflow on some settings, normal on others
    • Burnt-plastic smell from vents (overheated resistor/connector)

    How to Fix

    Replace the blower motor resistor; because resistor failure is usually driven by a worn high-draw blower motor, inspect the motor and replace it at the same time if it's noisy or drawing high current. Check the blower connector for heat damage/melting and repair as needed. Confirm all fan speeds work after the repair.
