Hey guys I always appreciate your help. I'm wrapping up my intake swap and I can't get it to start. I have spark and fuel in the rail but I also have fuel in vacuum lines. Is that indicative of a fuel pressure regulator? Would that make it not start? I'll post some fuel pressure numbers later tonight and test the injectors with noid light. Thanks again for any advice guys.

 

Torn diaphragm in FPR will send fuel through the vacuum lines

 

You think that would cause no start condition?

 

I would have to say yes. What is your FP on the rail? Do you have fuel coming out of the FPR when you turn the key on and the FP primes?

 

I will check fuel pressure when I get home and let you know. I didn't see fuel coming out of the fpr even with the line off

 

If you have a hand-held vac pump/gauge throw it on the FPR and see if it holds. If not, the diaphragm is shot.

Fuel pressure primes to 45 psi. I checked and I don't have injector pulse. I bought my distributor on eBay used so I'm going to start in there?
