Default 1989 Buick Regal 2.8 No Hot Start

I have an 1989 Buick Regal 2.8L FI with 58,000 miles. I've been fighting a starting issue. It will start and run fine cold. I can drive it 10-15 miles then it will stall and not start again until it cools off. It isn't overheating as far as the cooling system goes. I've replaced the ignition module and the crank sensor. Neither helped. No codes in the computer, no check engine light.

Have you checked the fuel pressure?

Yeah, you will probably have to ride around with a fuel gauge attached.....when vehicle is warm, you can try a tap test on your MAF and ECM.......

I am not familiar with this model but what you want to do is to list the things that can fail when they get hot. For example, I had a Ford once (can I say Ford here lol) that would run great cold but skip like heck when hot; it was the ignition module breaking down when it got hot. So that is what you need to do, find out the things that can fail when hot but operate when cold.

By the way, on some model cars, the temperature sensor does more than just indicate the temperature of the engine, the sensor is used to make changes to the engine based on the temperature of the engine. A friend had a bad temp sensor on his 94 GMC truck and it caused the engine to run horrible. He replaced the temp sensor and all was well.

Fuel pressure good by the specs. Its cutting out at high rpm, then as it comes down, it will go again. Can smell the catalytic converter. Shut it off after its warmed up, and it will fire then quit right away. If I press on the gas pedal, it will start, idle rough, then smooth out. If I let it set 10 minutes after its warmed up, no ignition fire. Pulled a wire, put a spare plug in it, and no fire.

Have replaced the ecm temp sensor a couple of times, but I haven't changed the warning light sensor.

sounds like the crank position sensor. or could be icm but since last time i had to buy one it was a third to a quarter of the cost of the icm i would try that first. its just a pain to get to, between the firewall and block, you have to get under and reach over the trans. after you take the bolt out the rubber ring likes to hang up in there and you just have to show it whos boss

That'* what I thought...crank sensor. I've put 3 in now, the 1st one was a bear, had to drop the oil pan and push it out from the inside. I changed it the same time I changed the ignition module this time. Still does the same thing, and doesn't set any codes. Does anyone no if the EGR could cause these symptoms, and if it would be tied into the ECM to set codes in '89?

very few sensors/devices can cause the engine to stall, it has a redundant "get you home" open loop mode. if the maf is going in and out thats one, crank sensor, icm, and pcm itself. if you are not using delphi or delco sensors that could be your length of service issue. or it could be a wire issue between the ckp and icm or icm and pcm
