Daeron: I know i know the EFI Bible is holy and all that, but honestly it did not help me. JayBee: The fuel pump seems to be working fine once he hit it with a hammer a couple times. The switch thing is a good idea, i've got some for my wipers, the Z motor crapped out, so now i have high speed civic wipers. much better, even with the one speed Took out the plugs and they were all black and wet, cleaned em up, redid the connections with the injevtors, ecu, relays and blew out the fuel rail on top. Now all 5 cylinders are firing, yes five. The frontmost injector crapped out on me. I have no idea how if stopped working completely, or how it running again, or why during that process one of my injectors died. We did the old screwdriver to ear to injector trick and all other five click along great, but you can barely hear the first one at all. Just about to replace it with one we picked up from autozone for $42. I was worried about replacing all injectors at the same time. Partly because getting the fuel rail off is a *****, and second just because one has already gone bad... and i dont want to risk 5 more

Thanks in advance for reading this, and hopefully you can help. I've got a 78 280Z that has its fair share of problems like all Zs, but this is one i cant seem to find the answers for anywhere. Checked all the forums here, atlantic Z club, the efi bible, the FSM etc. So the problem goes as follows.. For about 3 months now my z will have this nasty habit of dropping the RPMs to 500 while idling. I used to pump the gas pedal or just hold it at a steady 3 or 4000 RPM and it would eventually right itself and go back to idling and driving proper. I thought that it was clogs in the fuel lines and if i just kept pressure on the fuel lines they would bust loose and everything would be fine, but i guess i was wrong about that. This past Sunday i was driving and it dropped to 500 RPMs again, but this time, no matter what i did, it would not right itself. It sounds almost as if only half of the engine is firing while the other half sits there. So i drained the tank, cleaned the pump, new fuel filter, cleaned the lines (and i found a lot of black powder gunk, a LOT of it) put everything back together thinking, "That should do it!" But it did not. In short: I can start my car if i give it gas but it will not stay running. And while it's "running" it only has half the RPMs it should. when i turn the key to the ON position the fuel pump will turn on for a split second and then turn off. My dad and I think that the problem is the fuel pump relay not sending power to the pump. I'll try to be as helpful as i can to anyone who wants to help.
