I know the question has been posted, but I can't seem to find the answer. I have a 93 Lumina Z34 and its been stalling out on me over the past few days. This first time it took about 10 minutes to start back up and i had no problems once it did, then the second time I had to have it towed because even after an hour it wouldn't restart. The plugs and ignition coils are all brand new, the fuel pump is only a few years old and there is fuel in the rail. I do not get a check engine light or anything before it sputters then stalls. any suggestions or advice would be extremely helpful????

 

Check the fuel system. Check the injectors.
