no start when warm

[emerica12124]

Recently got this 92 awd talon.

it has a 3052 turbo, front mount intercooler, dual fuel pumps, 1600cc injectors,
AEM ems, 272 cams, fpr

It will only start when it is cold.

Runs and idles fine with no throttle needed. About 5 minutes after started car begins to die. Throttle is needed to stay running.
I let it die then got it to restart right away once. But wanted to die.

The coolant temp is working and reads good on the computer. I cannot figure out why it wont start up hot.

Any ideas? I have been reading all the posts on no start when hot with no luck.

I Tested for spark and injector pulse and have both.

have you contacted previous owner, try seeing if both fuel pumps are kicking on, if so have you checked the plugs, you are dumping a lot of fuel and what kind of plugs are you using i used to use ngk7's i believe, after that try coil pack replacement after that i'm lost hope this helps you

Does it sputter or backfire or anything when trying to start it when it is "warm"? Also define warm. Are you talking operating temperature? If so what is that temperature?

I talked to last owner. He said no problems. I knew of him before so i know its a new problem.

He said there 2 step colder plugs NGK. Should I stay with the 2 step colder? Ill be getting new plugs and wires tomorrow.

It doesn't sputter, misfire or backfire when running.

"Warm" is when started cold and let run for about 5 min. Starts happening after about 5 min when overnight sitting.

Update - Took it down the street cold. Made it to the top of my hill. Died at top. Wouldn't start. Cranked like always.

I bumped started it, and it fired right up but you have to keep the idle up or it will die.

So it will not crank start and stay running. Its really getting on my nerves. I wanted another talon to mess around with... I guess this is what I get. HAHA!
