well i was driving my daily driver tbi going 60mph when it just cut off real fast and now it wont start back up. Battery is fine it cranks and turns over but doesnt start pulled the air cleaner and the damn fuel injector will not spray the fuel pump is working and when i disconnected the fuel lines coming out of the filter it sprays out fuel likes its suppose too. What is the problem do i have a bad injector not even one drip sprays. Car has had full tune up 3 weeks ago.

I would check out you oil pressure sender. If the ECM see you have no oil pressure, it kills he fuel. If memory serves me right. O, and check for spark, cause I think your ignition module plays into the injectors firing. No spark, no fuel if the ignition module is bad, or the pick-up.

I had the same exact problem with my firebird this summer. After many hours of diagnostics I finally found the problem.
The ignition control unit which is located under the distributor cap. it is the black plastic box with 2 screws in it. Take it off and get it checked out at autozone does it for free.

Save yourself sometime and start with the ICU.

I second that opinion. I wish I would have had a place to just check mine recently..argh

replaced the icm still no spark or fuel
