Fuel is not flowing to engine, changed fuel filter but still not running.

If you hear fuel buzz and run back near tank,,and still wont crank you Needs fuel pump in tank,,,try taking a piece of wood and have someone try to crank it while you bang on the center of the fuel tank with the wood,try it a few time if it dont work the first time,,also you can rent a fuel pressure checker from auto zone to check it,,, think its suppose to have a min of 65 psi to crank "when you turn the key to on" not start,,,,and 45psi when its running

Find and check the fuel pump relay. You can test it with an ohmmeter. Place one probe on each side of the relay. It should have a good reading.
Also, when key is place in ON position, you should hear pump turn on for a few seconds. If not, check wiring to pump and to the relay with a voltmeter and see if there is power.

Have someone to stand back side of the truck and listen to see if they can hear the fuel pump while you are turning the key if they do not check the fuel pump relay first and that test ok then it maybe your fuel pump give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair Manual for your SUV

Did the engine just quit going down the road? or was it parked and then would not start? Did it have fuel before you replaced the filter? Did you check all the fuses in the fuse box. I think 2 of the fuses is marked ECM, check both Fuel pump relay? swap it with another relay in the fuse box. You should hear the pump come on for 2 seconds when you turn the key on, do you? If not as you are cranking the engine have someone rap on the bottom of the fuel tank with a mallet or block of wood, or hammer and see of the pump will run. If that gets it running, the pump is bad and will need replacement.
