Need help car starts then dies w/n please
its got spark its got fuel pressure it has no codes what so ever I have know idea.
it will fire up run less than a minute then shut off like turnning the key off. Then its hard to start and have to let sit a couple of min, before it does the same thing again. Any ideas or info would be greatly appreciated thanks Timbo.

I'm assuming that you checked that it's got spark and fuel right when it dies. Make sure when you check for fuel pressure that you use a gage rather than just poking the schrader valve. You need to make sure the pressure is high enough. The only other thing I can think of is to make sure the injectors are opening and closing. Maybe your computer is screwed up and stops sending the injector pulses after a minute.
There's two ways to check the injectors: #1 Take a screwdriver and touch it to an injector, then put your ear up to it to see if you can hear it clicking. #2 (more accurate) Unplug an injector harness and touch a grounded test light to the positive terminal. If you don't know which is positive, test them both. The test light should flash, showing that the injector is recieving pulses. Hope this helps.
