So I've just changed the fuel filter, truck won't start. Bleeding at the LP banjo (test valve on it?) doesn't show any fuel. I pulled the filter, bumped the pump and can't see any flow into the filter basin. Does this mean my stock electric pump on the block has failed? And no I don't have a presure gauge yet, just change the filter once a year with no problems till now.

 

Most likely its failed or sucking air. You also may of done injection pump damage. Who knows how long you may have been driving on little to no fuel pressure?

 

can you hear the lift pump ? if not it could be bad or a blown fuse /bad relay . if its running it could still be bad stock pumps are very un reliable

 

Yes, it's still running but it doesn't sound nice, strong and consistent. It's a little on the wimpy side and the pitch changes. I'll price out and change it tommorrow. I know I should have the gauge, everyone here says its the first thing to add. I just kept thinking to by an Edge. Time to get off the pot.

It looks like I can change it from the top without having to drop the starter. Any tricks or problems I should look out for? I can remove it and just need to undo the banjos on both sides. Piece of cake, right?

 

The stock pump fails a number of ways. Most commonly, the bypass spring fatigues so the pump ends up just sloshing fuel around inside itself, pumping fuel in an internal loop and not push the fuel out the door.

Other common failures are brushes and brush wires. The brush wires inside them are cheap and spindly, and the wires are unsupported against vibration. So eventually, the wires fatigue and break, and the pump goes completely dead and won't even come on.

Swapping one is simple. The banjos are M12s (should be 18mm hex, iirc) and the mounting bolts to the block should be M10s (16mm hex).

 

The diesel truck shop up in Nanaimo ( they work on passenger diesel trucks like ours and the other two fake diesel brands) sold me an Airtex E7153 fuel pump. It fit right into the stock location with a couple new fittings and is guareented for four years. No less than 12 psi WOT, steady 20 psi the rest of the time. Although buddy at the shop said the six month timer has now started for my VP to fail, dead pedal soon to arrive. So I'll be back to buy one of those.

i had noticed a couple of times starting the truck a quick smell of burning, which is now gone. I suspect it was the VP complaining, although I didn't know any better. And now I do notice the truck seems to be just a bit friskier and livelier with the new pump.

Thanks for all the help. Once again this forum shows why it's the best.

Best Regards,
