Your not trying to start this with the Air Intake disconnected ??

 

No codes. No haven't tried with the intake off. Thinking it may be a loose ground. I've checked every fuse and replaced relays. I'll try taking the intake off. Appreciate all the ideas.

 

It will not start with the intake off that is why I asked

You just need to go through circuit by circuit .

Sometimes just swapping parts unless they are tested as failed can make things worse

 

Still nothing found....will update as I get through all these wires...might be a while.

 

Might have found the reason it won't run but not the cause. Injectors lose ground when the engine cranks...anyone have an idea what I've messed up?

 

It lives!!!!!! Wiring harness ground was loose! So simple and checked almost every other wire before I got there. Idles a little fast and gonna change some old vacuum lines but it runs like a champ! Thanks all!!!
