I would start by checking the FPDM ( Fuel Pump Driver Module ) on the cross member by the spare tire.

Drop the spare tire, and check the FPDM to see if it is cracked. My 2006 the case was cracked when I changed it, sure it was not too long before it would have cracked the circuit board

Taken pointing the front of the truck, driver's side rear tire on the left of the picture, the cable to the right is for the spare tire.

This is how far mine had cracked

This is what the fuel inertia switch feeds power to, and the PCM controls to operate the fuel pump.

I have a 97 Bravada that won't start. When I turn the key on the radio and other accessories turn on but the dash never turns on and the truck won't start. It turns over just fine. I checked the...

Yes, it is electrical alright. But probably not due to the fuel pump, I would bet the pump won't turn on as long as the dash won't, cause the ignition system is not on. It's probably either a blown fuse for the ignition or a bad ignition switch. So check all your underhood fuses.

2005 freestar, turn key on and fuel system won't pressurize. Spray a little starting fluid and van runs fine, system won't pressurize for initial start.

i would check the fuel filter if thats not it then it will most likely be the fuel pressure regulator make sure the vacuum line didnt fall off of it if that checks out then id say its your pump good luck i hope this helps

Engine cuts out 1.8 petrol but starts up straight away then drives then cuts out? suspect fuel filter?

You are right to suspect a fuel supply problem. However, what you describe can also be the symptom of a bad ignition coil pack/ignition control module. Another possibility is a fault in the fuel injection system. If your car is still on its original fuel filter, it won't hurt to replace it, and probably you will find all kinds of gunk in the filter, which is normal. At the very least this will eliminate the possibility that the fuel filter is causing the problem. If you can find inexpensive coil packs and ICM, try swapping out the old ones to see if this makes a difference. In any case, you should check for engine computer error codes with an OBD scan tool, even if your check engine light is not on.

Cars turns over, but will not start

fuel pump??? two ways to test one good, one not so good. fist, without cranking over the motor, have someone go and listne in the back where the fuel tank is and try and here if there is a whirring sound when the key is put in the on position. you might not be able to here it. second (have a rag handy) undo one of the fuel lines and see if there is any pressure going to it = if none = dead fuel pump. third way....if it is easy to access the top of the fuel tank where the pump is, do so. remove pump and see if it works. also, if its an externally mounted pump, gently tap it with a wrench on the outside of the pump casing...this an actually make them work for a short time.

Ignition timing would be #1 on the list. Also check your plug wires, or change them. Check your air filter, and change the fuel filter. It could also be your egr system, faulty ignition coil, or a vacuum leak at the intake manifold.

Turns but won't start

Fuel filter is easy enough to find. Look under the car in front of the rear passenger wheel.

After that, suspect the fuel pump.
