Cranks, starts...wont stay running unless im spraying started fluid.

I have good fuel pressure, injector pulse, spider injector is working, egr is good, sparks good, voltage is good, will run smooth untill i stop spraying.

No hoses are loose.

Whats could be the problem?

 

Sounds like a fuel problem or a vacuum leak, otherwise the starting fluid wouldn't help. Make certain once again that all hoses are connected and there are no vacuum leaks. I had a similar problem with my 99 S10 4x4, I had removed the elbow directly above the throttlebody and neglected to press is on properly again. Looked fine until I looked close and saw the gap at the back.

 

What elbow? The air cleaner thing?

 

Yes, it goes from the air cleaner to the maf sensor, then through a 90 degree elbow into the throttle body. Or at least it does on the V6 models. I would check that. Will it run at all without fluid?

 

Oh, the black tube? Wouldn't run hooked up. Only with starting fluid.
