tpi doesnt run
 

I'm having problems with a 1990 trans am if I spray starting fluid it starts up and runs for a while then cuts off on its own after it warms up then when you try to restart it it won't start the previous owner changed the dist and ICM the car only starts with starting fluid and runs for a while the fuel pressure is good 42 pounds I think there's no injector pulse on start up

Check to see if the injectors are pulsing with a noid light

Wonder if the injectors are shot..

I'm going to borrow a noid light to check the injector pulse

ohm out the coil as well while your there just to be sure it isnt that

Any codes?

I swapped coils it still does the same thing

I'm with Mike on this one, any codes present? Would help narrow it down. Though it is possible that the car isn't running long enough to throw a code. Sounds like a fuel system issue to me for sure.

Check the injectors with a noid or ohm meter. Then put a fuel pressure gauge on it. Report back when you have these results

Just an after thought if its a MAF car unplug it and try it then. But I think 90 is MAP but I can't remember

Thanks i have to use the ohm meter I will ask a friend of mine if I can borrow a noid light 90 is speed density I will try to check it this week
