Help!! Fuel starvation problem
I just replaced the intake manifold gaskets and I have it all back together and the car will not start. I have narrowed it down to a fuel starvation problem. I can spray basically dilouted ether into the throttle body and I can keep it running but when I quit it dies. I have checked all lines and they are tight. I have fuel pressure. The fuses are good for the injectors. How do I test to make sure that the injector electrical plugs are working? If they are working how do I test the injectors themselves, can I do this without taking them out? Is it possible that some of the RTV that I used on the gaskets could have gotten on the end of some of the injectors? I am at a loss on this please help!!!

Re: Help!! Fuel starvation problem (corvette0096)
I'm getting one from a buddy of mine today, will try it after work. It was late last night so put it up for the night. I know I do have fuel getting to the fuel rails though, although you are right I do not know how much pressure. By the way does anyone know what pressure the fuel system should be at?
I am thinking it is either a partially stopped up fuel filter, which I will find out after work, or I have some injector plugs swapped. Any thoughts on these two theories.

Not that I cat visibly see, one of the first things I looked at. I can depress the hook-up for the fuel pressure guage and I get gas out of it, just don't know how much pressure yet.

Re: Help!! Fuel starvation problem (hz900)
OK update. I was able to check the pressure during lunch and it checked out fine. Mech. buddy gave me a test light node thing to test the injector wires, guess what, I have no power to the injectors. I did not unhook any wire connectors having to do with these but maybe in moving everything around one came loose. Mech. told me that there is usually a plug somewhere behind the distributor befor it goes into the main harness that goes into the firewall. Couldn't see anything without removing the dist. but can anyone tell me if there is one there? Also are there any other fuses, circuit breakers, or relays for the injectors other than the ones in the fuse box?

Battery -> ignition switch -> fuse -> inj conn
That is off the top of my head. (not certain)
W/ key in ON position, you should have +12V on one side of the injector conn, the other contact is the ECM, connection.
Make sure you have power to the fuse. (Easy to check)
