Weird 350 too no start.

What's up guys i got a 91 gta with a 350 tpi....yesterday I barely started it to move it to work on it it barely started and sputtered......the fuel filter was clogged...i changed it and now it won't start at all....i have 44 psi when the pump primes..i took the pump out to make sure it was not clogged...i checked all the fuses they are good. I'm thinking a wire or something broke when I moved it. Any ideas would be great as I was barely got to get it registered to drive it.

Re: Weird 350 too no start.

Have you checked for spark and injector pulse ? Sounds like you have spark if it sputtered.
Do you have the original multec injectors ?

Yes i have spark...it was running yesterday when I moved it...the fuel filter was clogged. I had to get the fuel pump to prime 3 times before it would start. So I changed the filter..no i have new Injectors the motor was rebuilt. But now it won't even start just cranks.

Re: Weird 350 too no start.

Sounds like a pretty basic no start/no run issue. Turn to that section of the service manual, and start troubleshooting. Fuel? Fire? Timing? Work the problem.

well that's the weird thing is it was running when I moved it it had no check engine light or nothing. I'm thinking a wire broke somewhere. It had spark and fuel like ibsaidbthe psi is at 44 when I prime the pump. I hear the injectors getting the fuel

Get a noid light, vats or bad icm. A icm can still work and give spark but fail for giving injector pulse.

Re: Weird 350 too no start.

I'm sure you could find one used, but they're all over ebay new. I needed one a few months back. Think I paid about $15 bucks.
