First make and model would be a big help .check to see if you you have power to ingnition sys if so check to see if spark plugs are firing if all checks out proceed to oil pressure sending unit if you have no spark check crankshaft sensor this will get you closer to finding out trouble and by the way new fuel pumps can go bad just a thought

SOURCE: no power to fuel pump. I have power up to the circuit opening relay.

I am not positive how the electronics are routed on a later model truck but I had this same problem on my 89' with a 22re. It turned out that the oil pressure sending unit was in the fuel pump circuit so as to not allow the engine to start with no oil pressure. I changed my sending unit and the truck fired right off. Hope this helps.

Am working on the same problem. Have narrowed it down to a couple of things. The primer curcuit on my '88 is not work off the computer it will not prime the fuel system. Have found away around that by putting in a new relay off the starter line. The main problem though is that the check valve in the fuel pump is shot and allows all the fuel to drain back into the tank. It takes too much time to get the fuel preasure up if the fuel system is completely empty. Am going to replace the fuel pump and see what happens. The fuel pump relay is located under the glove box, have not found diagram map of the relays there, there are 10 there. If you need a wiring diagram for your car, go to autozone, can print off a wiring diagram there. Good luck.

New fuel pump, two weeks later it wont work

If there is power to the pump, and it's not running, you have a faulty pump, and should be able to get a refund. Check your fuse and relay if there is no power.
