Why does my Chrysler LeBaron die while driving or cut off at stops?

Short answer: On LeBarons with the 3.0L V6, one owner whose car died after about 20 minutes in the heat caught the cause by leaving a fuel pressure gauge hooked up: pressure dropped to zero when it died, so the fuel pump was cutting out. Another owner whose car cut off at stops fixed it with a new EGR valve and a new EGR solenoid that had a broken pin. Read the flash codes first, then test fuel pressure while it's acting up.

Symptom: The car runs fine, then dies while driving, often after it's been running a while on a hot day. Or it cuts off when you come to a stop, with the idle dropping toward zero, and may restart after a few tries.

What to check first

1. Read the flash codes. Turn the key ON-OFF-ON-OFF-ON and count the check engine light blinks. Write the numbers down.
2. Have fuel pressure watched while it dies. A gauge left hooked up where it can be watched tells you if the pump quit.
3. Check the EGR valve and its vacuum solenoid if it stalls at stops. A valve stuck open acts like a big vacuum leak at idle.
4. Look for vacuum leaks around the intake with the engine idling.
5. On the 3.0L, ask about the crank sensor if pressure and spark both check out.

Likely causes

1. Fuel pump cutting out when hot. The 1990 owner's gauge read zero right when the engine died, and a Chrysler dealer tech agreed it was the pump.
2. EGR valve stuck open or a bad EGR solenoid. The fix in the 1994 thread, along with a solenoid that had a broken pin.
3. Vacuum leak. Members suggested checking for leaks before buying parts.
4. Idle air control valve. Suggested in an older thread about cold-weather stalling.
5. Crankshaft position sensor. Mentioned as a suspect on the Mitsubishi-built 3.0L.

What it usually costs

No owner posted prices. An EGR valve and solenoid are moderate parts; the fuel pump is in the tank, so labor is a big part of that job.

Is it safe to keep driving?

A car that dies in traffic is dangerous: you lose power steering and power brakes get harder to use. Don't drive it on busy roads until it's fixed. Verify with a mechanic.

DIY or shop?

DIY for flash codes, vacuum checks and the EGR parts. A fuel pressure test is easy with a borrowed gauge; dropping the tank for a pump is a shop job for most owners.

Recalls, bulletins and complaints in plain words

• Related recalls: NHTSA lists these recalls touching this area of the Chrysler LeBaron: 88V105000 (1987-1987 model years, fuel system, gasoline). Check your VIN at nhtsa.gov/recalls. If your car is part of this recall, the dealer fixes it for free.
• Plain words: Recall 88V105000 covered fuel leaks in cold weather at the engine-bay fuel hose connections on some 1987 models. It's about leaks, not stalling. If you smell gas under the hood, don't drive it until it's checked. Verify with a mechanic.
• NHTSA complaints: 208 keyword-matched complaints for Chrysler LeBaron 1987–1995 (of 622 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-26; keywords: stall, dies, no start, cut out, idle, hot, fuel pump, hesitation, EGR). This counts complaints that mention these words. It is not a defect finding.

What owners report

• In 1990 Chrysler LeBaron 3.0L V-6 dies in heat on Car Talk, the owner said the car died after about 20 minutes of driving and wouldn't keep going. A new coil didn't help. With a fuel pressure gauge taped where it could be watched, the pressure read zero when the engine died, which pointed to a fuel pump failing on and off. A Chrysler dealer technician also guessed the pump. A duct to the engine computer turned out to be a red herring.
• In 94 Chrysler LeBaron cuts off while driving on Car Talk, a 3.0L LeBaron cut off at stops with the idle dropping close to zero, and the owner read several flash codes. Members suggested a vacuum leak check, fuel pressure, and the crank sensor. The owner reported the fix was a stuck EGR valve plus an EGR solenoid with a broken pin.
• In 93 LeBaron stalling problem on Car Talk, an owner with cold-weather stalling got suggestions to look at the idle air control valve, possible flooding, and overdue basic maintenance.

Quick tip

Stop guessing on an intermittent stall. A fuel pressure gauge left where you can see it while driving can tell you in one drive whether the pump is quitting.

Vehicle focus: 1987–1995 Chrysler LeBaron, mostly the 3.0L V6.

Safety / mechanic note

Stalling while driving can cause a crash. Never leave a fuel gauge where fuel can spray on a hot engine. Verify with a mechanic.
