I had a burnt connector (twice) between the relay in the trunk and the fuel pump. Had to bypass the ground lead and take it straight to ground. Then the battery side burnt out and had to replace both connectors with male/female spade connectors.
Have you tested out the fuel pump? check for plugged fuel filter?
plugged fuel lines to the fuel rail, injection pulse at the injectors? power to the fuel pump relay? grounds needed to make certain systems work must check those also. get a wiring diagram of the fuel supply system and back trace all the wiring and see if you have power and ground and signal.
Locate and replace the fuel pump relay and see if it will start then. Also, make sure that the battery terminals are clean and secure; also on the starter, and the ground (at chassi - or block, wherever the ground leads).
Please let me know if you need further assistance.
I doubt you have a fuel issue if you replaced the pump. Try this to bypass the fuel pump. Spray some quick start or brakle cleaner into the throttle body. If the car still does not start then the problem is ignition related, NOT fuel related. If it does start then go to mitcell1diy online , search. You can get all the diagnoses info there.
Yep!.. the problem is electrical wiring (that's only if you've VERIFIED the replacement pump is GOOD!). If you don't have POWER and GROUND at the fuel pump connector, doesn't matter if the pump is good or not... if the pump isn't receiving power (and there's a questionable ground), the pump will not operate correctly.
It really sounds to me you have a grounding issue with the pump and sending unit.
If the gauge is indicating a past full reading, the ground is open. An open or poor ground will also cause the weak fuel pump pressure.
Find the black wire at the fuel pump connection and measure resistance to ground, should read near 0.00 ohms.
Good luck and let me know.
The ground? You'll have to be more specific. There are several grounds involved in starting the car. Whichever it is, it'll have to be repaired. This repair should be fairly simple -- replace the broken cable or clean the connection, then replace. There's no way to bypass the ground. Let me know which ground it is, and I'll try and look it up in the repair manual, and give you some tips on how to track it down and fix it.
