replaced fuel pump, fuses, relay a

Test the fuel pump relay its in the relay center

we already replaced it with a brand new relay

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.

ok I'll try that. how do I do that? its a brand new pump so I would hope it isnt defective

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.

Thanks

ok thanks

I changed the fuel pump in 1997 crown vic and it still won't start and don't hear the fuel pump

Check and test fuel pump fuse, fuel pump relay and inertia fuel cut off switch

with key to just ON, does your check engine light come on along with other wraning lights?

i need to know easiest way to remove fuel pump

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.

where is the gas pump for this model

Since it will run with starting fluid, that tells me the engine isn't getting fuel. Either you have a bad pump, plugged fuel filter, or the injectors aren't getting power. When you check the fuel pump pressure, let me know what you find.

My neighbor got it taken care of. While we were diagnosing the the fuel system we checked the fuses and electrical. We had dropped a fuse label under not in use in the diagram but was completely not the case.

Glad you got it fixed.

Can someone please tell me, if the problem I'm having is my fuel pump or fuel injector?, I went to the local store earlier tonite and my car just died out while I parked it,after getting back in and starting it, the car would not start but sounded like it wanted to kick over, a local auto person came by and siad it's either my fuel pump or fuel injector( hm at this point I don't think I'll take either of his words) please can someone help me out here?and how do I check to see which is what?, and how do I replace the fuel pump or fuel injector on my 1997 Crown Victoria?

When you turn key to On position do you hear the fuel pump humming for a few secs?

Are you mechanically incline to pursue this issue. If so comeback and we'll go for broke. If not bring her in. The reason am asking this one can be a nightmare its not a simple fix.

o.k. when I tried to start it, I really don't recall if it made a humming noise,, but a man who had ether squirted it in the fuel area, and it almost started, well it actually did start but didn't stay, it died out right away,does this anawer the question?, does this mean it actually is my fuel pump?

We won't know till you check whether it has power to the pump and have the correct pressure.

Well if it ran on ether...we know it has spark.
This rules out crank sensor which have personally owned two 4.6 L that the crank sensor went out on...although it is usually a part fails rarely..

Take the gas cap off and put your ear to the hole...see if you hear the pump spinning...humming for about 2 seconds when someone turns the key to on position. You probably won't..
My guess is the pump is not spinning..
There is a a fuel pump fuse under the dash I believe on 97 check owner's manual for location or I can find it for you.
There is also a fuel pump relay under hood Manual will show this too. You can swap the relay for another one that looks like it under the hood to try to test...the relays don't go bad that ofter though.
Fuel pumps on Ford full size cars are beyond excellent in longevity....about the only thing that can hurt them is running it almost out of gas or out or gas often..

There are more ways to trouble shoot it like bypassing the relay etc...but it gets a bit technical...
Let me know if you want to try other diagnostics.

I had an issue with the fuel too on my 97 cvpi.
mine would start after a lot of cranking then would run, the wouldn't get out of the driveway. We thought it to be bad gas (which it had set for awhile). We spiked it up enough it should start up and run but no it did not.

The tank in the cv is a real pain in the butt to get to, it is hidden nicely above the rear axal.

After removing the tank we drained the nasty old stinky gas and had seen foreign material and debris. Closer inspection revealed pieces of rubber and dirt.

Out came the fuel pump, that revealed that it had corroded and the rubber on it fell apart.
Replacement of the fuel pump on the police model turned a bit harder to find than normal considering that most police have turned to newer models. The pumps push alot of pressure. If you were to take off the line on the filter located under the driver's side rear door and turn on the key, you would see fuel shoot all over the place. this is a good sign that the pressure is there. We replaced that filter too considering the debris in the tank and that we had been running it alot.

We put it all back together and added a couple gallons of gas, then we checked, double and triple checked that there were no leaks and fuel was again flowing.

We then started the car and WOW! IT WORKED, we filled up at the station.

A week later the car died on the freeway. After an hour of "WTF", it started and continued to run on for about 3 miles and died again. Once started, the car ran fine for 2 more weeks and there it went again, just dieing over and over. I pulled into a parking lot and went over a speed bump and I was able to keep it running, then 2 more hours of "WTF" before I towed it home where the right diagnostic tools were.

IF I PAYED ANY ATTENTION AT ALL, TO THE LITTLE STICKER ON THE CORE SUPPORT UNDER THE HOOD, I MIGHT HAVE SEEN THAT IF THE CAR DIED REFER TO THE OWNERS MANUAL THAT TALKED ABOUT THE "ROLL OVER" OR INERTIA SWITCH THATS LOCATED IN THE TRUNK.

It did not need to be reset, which is super simple, but the switch had a short in the wiring, shutting off the fuel supply, allowing the car to suddenly die. That could have cost me $300 if i took it in to be checked.
