Why won't my Chevy Celebrity start when it's warm?

Short answer: If your Celebrity starts cold but won't restart warm, test for spark while it's hot. The 1989 2.8 V6 owner in this thread had good fuel pressure but lost spark when the engine was warm, which points at the ignition parts that live near the exhaust: the coil pack and ignition module (a missing heat shield made it worse) and the crankshaft sensor. For stalling, the fuel pump relay is a known weak point on GM cars of this age.

Symptom: Starts fine cold, then after a drive and a short stop it cranks but won't start. It may start again after cooling for half an hour. Others stall while driving.

What to check first

1. Check for spark when it fails warm with a spark tester. No spark hot means the ignition side.
2. Make sure the coil pack heat shield is in place. The 1989 owner's was missing.
3. Have fuel pressure checked to rule out the pump.
4. Swap or test the fuel pump relay if it stalls and won't restart right away.

Likely causes

1. Ignition control module, coil pack or crank sensor failing when hot. Loses spark when hot, comes back when cool. A member said this pattern usually means the control module.
2. Missing heat shield on the coil pack. Lets exhaust heat cook the ignition parts.
3. Fuel pump relay. Suggested for the '87 that kept stalling.
4. Weak fuel pump. Rule it out with a pressure test.

What it usually costs

The 1989 owner said the missing coil pack shield was a $4.75 part, but it didn't fully cure the problem, and they had already spent a lot on parts that didn't help. Members said 1 to 2 hours of shop diagnosis would have been cheaper. Get a quote after spark or fuel is confirmed missing.

Is it safe to keep driving?

Not reliably. It can leave you stranded and stall in traffic. Verify with a mechanic.

DIY or shop?

DIY for spark tests, heat shield and relay checks. Sensor and module replacement are doable for a handy owner.

What owners report

• In 1989 chevy celebrity 2.8 v-6 wont start warm Im stumped! on Car Talk, the owner found good fuel pressure but no spark when the engine was warm. Members noted the ballast resistor idea didn't apply to this fuel-injected engine and the owner found the shield under the coil pack was missing. Refitting the $4.75 shield got it running, but the next night it took five minutes to start, and a member said no spark only when warm usually points to the ignition control module.
• In 1987 Chevy Celebrity - Keeps stalling Out on Car Talk, a Celebrity kept stalling. A member suggested the fuel pump relay and the crank sensor.

Quick tip

Carry a cheap spark tester. Testing the moment it refuses to restart tells you whether to chase ignition or fuel.

Vehicle focus: 1982–1990 Chevrolet Celebrity, mainly the 2.8L V6 with fuel injection.

Safety / mechanic note

Stalling in traffic removes power steering and brake assist. Verify with a mechanic.
