Fuel Pump

[nhigdon11]

The fuel pump has stopped working. I replaced it and it is still not working. The engine will crank but will never start. Wife drove it to work the other day and parked it and it has not started ever since. I have looked at the fuses and the relays. I have switched them around and not had and luck. Any suggestions? It is an '03 le7.

thanks

This is a frustrating problem. Noticed loose terminals and tighten them. Had a code reader and got po463 "Fuel Level Switch A circuit high input." Cleared code. Still not starting. Looks like I am getting current to the fuel pump, but I never really hear it prime. Help please.

I took a light tester to the terminal end of the fuel pump and I am not getting any current. I light tested the fuel cutoff switch and was able to get light there. I "jumpered" that to make sure current was flowing past the switch. From there, I am not sure what to do.

I am having the exact same problem with my 99 Disco II. On top of your same issues, I'm not getting any spark on my plug wires either. This indeed is frustrating. If you resolve your issue please send me the fix info or aI will send it to you if I find the fix.

Crankshaft position sensor, maybe? Are you getting an RPM signal?

[nhigdon11]

I am in the process of replacing the crankshaft sensor. its on order and should have it today. i am not sure about the RPM signal. Do you know what test I need to do to check for that. If you mean when it cranks, I am not sure. I will have to check on that.

SUCCESS!!! This was an expensive undertaking, but none the less fixed. It actually was the crankshaft position sensor that went bad. It is not an easy undertaking on the '03 as there is not enough room for your fingers on one hand. Getting it apart was not too bad, but getting it together was a completely different story. A pair of 14" angled needle nosed pliers will be your best friend for this project. Especially when getting the wires reconnected.

So the moral of this story is to change the crankshaft sensor if the fuel pump stops working. sensor was about $70 at Napa and the fuel pump was about $450. Hope this helps.
