car starts then wont start
First off let me say its an 89 formula was LO3 now has 92 tpi.The car will start and run great one or 2 times,then I shut it off and try to start it again and it just cranks.Then later in the day it will go through that same thing.When it wont start it does have fuel pressure at the rail and spark but will only fire on starting fluid and run that out.It almost appears like the injectors are not firing?

Re: car starts then wont start
Yeah Dude I got almost the same problem. I Have an 88 Iroc with 5.7 350. It was running great one night and then the next morning nothing. But I have no spark, No ideas how to fix it, so I just started pouring money on the problem (New spark plugs, new wires, Cap and rotor, New coil, Hell I even added an Msd 6AL ignition box) but still no spark or ignition. I talked to my local mechanic and he said that the stock wiring harness sometimes breaks. So I need help as well
