Pull off a spark plug wire, stick a screw driver into the plug wire where it was attached to the plug. Hold it next to the block while someone cranks it over and see if there is a spark jumping. No spark then it is ignition related . Spark, then probably fuel problem and a fuel pressure guage will help ID the bad component. ie: pump, FPR etc. Any codes?

Not all of us have these nice tools to diagnose. Fuel Pressure guage, Valve spring clearance tool, etc...I have no special tools. Wich is why i get screwed when something breaks

Re: HELP, FUEL PUMP JUST LET GO???? (C4Dreams)
Change the fuel pump and relay at the same time, The relay is by the battery. As far as the one out of the GN, You will have to ask the dealer on that one. :cheers:

Check spark. Use an old spark plug, any spark plug. Ground the threaded area and hook it up and crank the car and see if you have spark.
If you have spark, check fuel. Have somebody turn the ignition to run (don't start) and listen to the fuel pump - should come on for 2 seconds or so. Does it? Go to engine bring a rag. Wrap rag around schrader valve on the drivers side runner, depress button in middle. Does fuel come out?

Re: HELP, FUEL PUMP JUST LET GO???? (C4Dreams)
How did you determine that it was dead? Did you check the FP fuse? Just curious.
I've heard that you should buy a new sock whenever you replace the pump. I got mine at Kragen's for $6, they even had it in stock (I was shocked).
Good Luck. :cheers:

Yes, the GN pump from '87 will work. You might have to snip your wires and make new connectors, but the pump will work and I think that one supports up to something around 450hp.
p.s.
In the early C4s the fuel pump will prime the system for about 4 seconds when you turn the key on. If you turn the key off you have to count to 10 and turn the key on again before it will prime a second time. If you turn it on during those 10 seconds it will not reprime the system.

It sounds like you aren't getting power to the pump or hte pump is dead for one reason or another. Before you go clipping things and throwing new parts out, find out why.
Disconnect the harness from the pump. Put a multimeter (+) lead on the switched 12v line and ground on the (-) one. A test light will also work. Have somebody turn the key on and watch the test light light up or monitor what voltage you get on the multimeter. As long as you get close to the same voltage you see on your dash your relay is most likely fine.

Re: (C4Dreams)
Did you check your fuel filter?
Have you checked your local parts stores (Autozone, Kragens, etc.) and see if they have a Fuel Pressure Guage you can borrow? Any local mechanic shops that will loan you one for a deposit? It will make things a lot easier if you can get your hands on one.
