Archived sputtering, bucking, no power?

[outlawram]

I was just taking my truck to get the transmission fixed and on the way there the truck started bucking, I could not even get it up to speed. I replaced the fuel filter and cycled the key 5 times and truck will not start. Is it My lift pump?

Check if you have any DTC's, engine fault codes. To do this, turn ignition on with-out starting, off, on, off, on and wait. Look at the odometer, it will flash any codes for the PCM and the ECM. This will hopfully point you into the correct direction.

After changing the fuel filter, if you have extreme trouble restarting, chances are the lift pump is dead or so weak that it can not pump fuel through the new filter and up to the injector pump. To see if the lift pump is working, find some place quiet and open the hood. Turn truck ignition on and just bump the starter without starting. Do not turn ignition off! You should be able to hear a wining noise coming from the drivers side back of the engine. If you do not hear it, chances are the lift pump is dead. If the pump is dying, it will sound funny, like the rpm's of the fuel pump is not correct or steady.

Hopfully it is not more than just a lift pump. Check for trouble codes.

Try crack open the 1/4 plug closest to the front of motor on top of filter ,bump starter you should get air or fuel out around the threads if just fuel tighten and hold peddle to floor try to start . If air bump again to get all air out . when all air out do as above . Pump some times run but do not pump . Is this the original pump that came with the truck . Suggest a fuel psi gauge set up . You may have to bleed lines to injectors one at a time Three should do it will run ruff till all air is out . Lol Ron Bissett in Metro Louisville KY
