Question about Cars & Trucks
So i tested the tps for voltage it sits @ 9.48 volts and drops to 0 volts when throttling. Is that normal?? While i was testing i kept hearing a clicking noise like a bad solenoid. so i traced it to the fuel system in the engine bay. The fuel pump relay is new and i still have the old one. But as this "solenoid" clicks the fuel pump corresponds with the clicking. not sure where to find this "solenoid." Any Ideas??? I was told that it could have a fuel pressure regulator valve or a fuel pressure solenoid. If so where is it located?? and do you have a part number??

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

could be a bad earth or [ground]
the power wire ma be brocken or have a loose or dirty connection
you neeed to trace it along its lenght to determine the fault!
so start at the pump & work back

Are you sure the spark is sufficient? I have seen weak coils cause your problem also bad coil wires loosing to much voltage to the distributor.
