I have a 2003 3500 4x4 70000miles. 6 miles down the road yesterday and the motor quit. Started again, stalled in seconds. Popped the hood checked fuses and relays,look to see if mice had eaten anything, stripped wire insulation... Started fine then drove back to town , no problems. Checked everything again, drain some fuel from separator, looked clean, no water. Started up fine again, got 10 miles out of town and quit again.
Now it won't start. Turns over, but won't go. Help!!!! We are stuckin San Juanico, Baja.

 

.....still have that junk lift pump mounted on the filter canister?

 

Its all stock, I have an edge chip, but disconnected it so I am back to fully stock

 

Any codes? Key on/off 3 times ending in the on position. Read the odo readout. Should be a P and the 4 digits after that like P0000. That will give us a better idea of where to start.

 

i,d suspect lift pump. mine did same thing for a week then just would not start. installing fass today

 

Just got back from the mecanico. We pullled the lift pump, blew some air thru it, put a direct 12 volt to it and it ran. put it back in the truck, drove it for 15 miles went great. As I got back into town the motor quit on me, started back up a couple times to make it back to the mecanico, now wont stay on. I'm going back in and will check it with a direct wire in position, may be I'll need to hot lead it to limp back home ?? I'll also check the "codes with the key". I don't want to spend several hundred dollars to get a new pump sent here, if thats not it.

 

Sorry to hear of your plight. I was @ Scorp in '88,not a nice place for a breakdown. I wish I knew of somebody going your way. When you get back,go with an aftermarket pump mounted on the frame rail.

 

got a code of p0628 off the key switching, anybody know what it means

 

P0628 Fuel Pump Relay Circuit Low, or Fuel Lift Pump Control Circuit Low

From https://www.dieseltruckresource.com/...n&onlynewfaq=1

If the pump runs as normal with 12V on it, it might be a relay going out. Over time the contacts will oxidize, making intermittent contact, just before they become insulators.

I dont see either listed on the fuse box list, do you know which positions they are in or maybe somewhere besides the fuse box?

 

it should be listed on the box feel and see if one is hot or not but when mine went out on the 03 it did the same thing i would replace it asap

 

rich, when your which went out , a relay or the lift pump itself? I checked everything in the box, all is like new I traced the wires from the top of the pump and everything goes to a box mounted on the motor. Do I concentrate on the electrical or pump replacement? It seems now like the system works fine until it gets up to operating temp, cuz it is starting now. There is no part in all of Baja, the mecanico spent all day on the phone checking.

 

Shoot me an address and I'll send you a functional lift pump in the morning. Free of charge. It came off my 03 when I went with the gdp unit and it worked perfectly. Lot of miles on it, but at least itd get you home.

 

direct feed won't help it.....but beating the C out of it may get it going. I've gotten alot of tow in's started by bumping the starter so it goes into 20 sec prime mode and tapping the pump with a hammer. Might get you along for a little bit of time. You'll hear it start to run if the "CPR" method works.

 

Cameroneod,
The best bet would be to DHL to Ciudad Constitucion, Baja California Sur. A friend is going to go in on Tuesday and can pick it up at the DHL office there.
I'll send you my e-mail on a private message and I can give you his name and mine for an authorized pick up. If DHL says it will be there before Tuesday I might be able to get a ride in earlier.
