I have a 1990 Iroc 5.0L and I recently changed the stock injectors to 19lb Accel ones. Ever since then my car has a tough time catching and starting. I have to put the gas all the way to the floor to get it to start. Has anyone ever experienced this before? I'm at a loss, and I can't figure out what it is. Any help would be greatly appreciated.

Thanks

Also it did not start doing this right after the injectors where installed it started about 2 months after.

 

When the throttle is held to the floor while cranking, all injector pulses are cancelled. Actually, I believe this "clear flood" mode will happen whenever the throttle is held open more than 75% on our old ECMs.

If you can only start the engine in this manner, you likely have fuel leakage from an injector(s), the fuel pressure regulator, or a cold start injector.

Oh, and Welcome Aboard!

 

Accel = Junk

Thanks.


smurfn'z28 why do you think that Accel is junk? do you have a reason?


I wish it was just a leak, that was the first thing that I checked. I forgot to add that it starts fine when the engine is cold, but most of the time when the engine is warm it struggles. But other times it's fine
