My car would drive fine and then the past week it died 3 times driving. It would just die any time. Now it wont start. We found out it wasnt getting fuel so we replaced the relay, fuse, filter, and fuel pump. As soon as we got it all back together the car will try and turn over but its not getting any fuel. The fuel pump is not getting any power. We took it apart again and everything is hooked up correctly and still doesnt work. The inertia switch is good and we have checked the wires from the trunk all the way to the front of the car. I'm going to dig into the engine compartment tom. Ive heard check the wires and what not but I dont know what else it could be. Any help would be greatly appreciated.

New fuel pump, relay-inertia switch good.

Heres a guide on testing wiring, it will help

Attached below is the wiring diagram for your fuel pump. Be sure you have all powers at the fuel pump relay and that power is going through the inertia switch )located in trunk)

Its not even getting any fuel at all. No fuel at the rails. The car will crank over but wont start up and run. Brand new battery, fuel pump, fuel filter, fuel pump relay, fuses are all good. I'm not sure what I need to do next. We followed the wires from the trunk forward and cant find anything wrong with them. On the bottom of all the relays they have some cuts on the wires but just through the sheathing and doesnt look like an issue. So the number one issue is we dont have power to the pump to get it started. Two is we cant get it started it has a new starter and the vehicle cranks over it just wont start up and I'm sure because its not getting fuel any help is greatly appreciated

Power the fuel pump from the battery and then check the fuel pressure if its correct-could be a defective fuel pump.

Agreed. However, we have learned many times that new parts are not good parts. So I would suggest we check the pressure just to rule it out as it will be difficult to find it if it is a faulty pump. So run through this guide and just make sure and we can go from there.

Would not there is an easiest way. You will need to drop fuel tank out. Remove locking ring remove assembly.
Good luck
Spray the hold down bolts for the straps with penetrating oil

(key on engine off) the fuel pump makes a rumbling sound. Car turns over but no start. Fuses and relays are good. Also the speedometer is also erratic when powered on

Have you checked fuel pump pressure to the engine? Have you checked for spark to the plugs? As far as the speedo, can you explain what is happening?

I got spark but don't have a pressure gauge to measure the fuel at the rail.
The speedometer shoots up to 60 and then bounces around 30 and 70. And it happens in sequence with this weird rumbling noise from the fuel pump.
Then I just notice my odometer keeps rolling too.

See if the car starts with starting fluid. Also, if it does start for a couple seconds, you need to rent a fuel pressure gauge at a parts store and check it.

As far as the speedo, it sounds like you have a bad vehicle speed sensor (VSS). However, it is odd that is acts up when you hear a change in the fuel pump. Have you checked for any ground issues?

Yeah I'm going to go check that out tomorrow. I had a hunch it could be a ground issue but don't know where to start. It'll run for a few second with starter fluid.
