the tank was clean and like I said the psi is great right now. I was thinking injectors or something but I am at a loss. I HATE SN95 intakes and TBs this car is pissing me off. Thanks for the feedback all.

 

any possible way the hose got kinked when you installed the pump? May have 42 psi at idle but not the volume under load?

 

that was what I was trying to say tommy,pressure under load isn't there

 

any thing is possible at this point. I will check that too. Thanks

 

I installed a new pump and come to find out the clamp was leaking on the hose inside the tank...chased fuel pressure problems for weeks. I all started when you shut the car off, the fuel pressure would drop to 0 w/in seconds and not holding like it should. new regulator, sent out the injectors and some other stuff before I dropped the tank and found the hose was leaking from my pump install...

 

Although dizzy has been mentioned and replaced... I had a dizzy go bad from Summit about 2 months after putting it in. The car would sputter and backfire under full throttle. Have you hooked up an FP gauge and watched it as you accelerate? That could let you see what's going on at least.

 

I'll say it again...one of my first mods is a good FP gauge on anything performance

 

plug wires , cap and rotor ? Is it missing then backfiring? Set timimg with spout conector disconnected? connected will be to far advanced

 

Have you tried putting a carburator on it? Lol

Good luck dude!
