Starts but dies when engine warms up

check coolant levels when cold and see that they are correct first

Check temp sensor for ecm. Some cars have two temp sensors. One for the dash gauge and one for the computer. The computer may not know its cold out.... the computer richens the air fuel for cold temps as needed for proper start.

I have the same year and stalls out occasionally in the beginning and now I can barely drive a quarter mile. All of the parts you listed I've tested and appear ok but what I'm thinking is not fuel because it would act crazy gasping for fuel but the camshaft and crankshaft sensors. If either of these are failing then the engine stops firing and dies. Also could be the alternator or battery. If not enough charge then the car could die. Mine dies like I turned the key off (and don't think it's ignition switch) and gauges all just drop to zero still sounds like engine is sort of on until I finally coast close to stopping and then dies and oil light comes on.

there is an idle control valve and an air flow meter that should be checked.check all the wiring harness and connectors to the crank and cam sensors.

Just an idea, but I think that you are onto something with the temperature sensor. If overheating was the cause of the head gasket to go, then I would imagine it would've fried the temperature sensor also. That would make it nearly impossible to start. The sensor should be fairly cheap enough to replace. Probably wouldn't even through out a code. My Mother-in-Law had the same problem with her Saturn, changed the temp. sensor and BINGO. No more problem. You just have to make sure you get the computer temperature sensor, not the fan temp. sensor. There are 2 of them suckers. Believe it or not. Hope this can help "with your idea". Best wishes.

its you ecu, they talk about this problem on ebay and they will even let you return it if that's not the problem... but something ecu go bad and make the car do that

i think mostly its hard to start because its a 92 eagle talon.. might be time to put 'er down.. ;)

flush your oil pan then change to a good oil. i use a rotella 15/40

kinda sounds like a relay. are you getting fuel when it won't start?

The INFAMOUS DSM Hot Start Problem

Here are a few things to try: 1) Block off your EGR valve. Sometimes these fail, and when they do, this is what happens.

2) Change your vaccum hoses, especially the one going to the fuel-pressure regulator. Sometimes this one leaks and creates problems for the FPR.

3) Change your plug wires. I'd use some MagnaCore wires. They're less $$$ than the stock ones, and they're 8.5mm opposed to the stock 6mm. The stock wires are no good, especially when raising the boost.

4) Clean your throttle body REALLY well. Make it spotless, including both sides of the throttle plate.

5) Clean out your intercooler. Do this by taking it out, dump about a gallon of gasoline into it, then shake it around and dump out. Repeat process until gas coming out is clean.
