Diesel Truck. I Have a 2004 Diesel f-350 super duty truck. Plain and simple, it wont start. I have taken apart the top fuel filter(close to the turbo hose) and found no problems, and the fuel pump works fine and pumps fuel into that second fuel filter. I found a blockage in the fuel filter and cleaned it up but it still wont start. *By the way it has air compression and the glow plugs work fine, it hits off of ether* Any tips?

I have a 1984 Nissan 720 Kingcab pickup with a 2.5L diesel engine, my problem is the truck sat from 1995 until 2010 with a full tank of fuel, I have drained the fuel tank and changed all fuel filters, the truck will not start on it's own (meaning) if I use starting fluid I can get it started and it runs ruff but drives very good, I purged the fuel system of air, but it seems the new spin on filter with water sensor leaks air around the sensor, can that be the only problem keeping it from startin

Water in fuel light just started to come on intermittently. Changed the fuel filters 3 weeks ago or 7500 miles back. Had never changed the filters on fuel or transmission since the first 80,000 miles. Truck runs smoothly, just that pesky warning light. How do you reset it? My truck has 215,000 plus miles on it. We did take it from Las Vegas area to Kodiak Alaska and back right after the fuel filter change.

My Suburban will not start, it cranks, but will not start. I recently had my fuel pump replaced, but the person who fixed it put the fuel filter on backwards and didn't connect my hoses back. so we end up driving it, not knowing the situation and the truck starts to choke and eventually wouldn't cut back on. I was told that the fuel pump shorted out because of this and got another one. it gets put on correctly this time, but it isn't getting any power to it. the truck will only start when they p

I have replaced the fuel filters and air filter. The dealer ship said it was the fuel pressure regulator. Any suggestions would be awsome with winter comming, Brent [email protected]

I was driving into town, stopped at the stop sign at the end of my street, and when I hit the gas off the stop sign, the truck died. After 10 minutes or so of trying to start the truck, it fired up. Every time I tried to start, the engine turned over freely, and would sputter just enough for a shake. I drove for 3 miles with no problems, until it died again as I stopped at a stoplight. I had suspected the fuel filter from the beginning, so I went and bought a new fuel filter and swapped it out.


It still could be the fuel pump. Sometimes they don't just quit outright. Go to the vehicle. Reach through the open driver's side window. Turn the key forward to the run position. Listen toward the rear of the vehicle for the fuel pump to prime. ... 2003 Ford Expedition

My truck has the 5.7 litre TBI. I can start my truck when it is cold but it will run ruff and when it starts warming up you can't rev the engine at all and it will die and you can't start it agian without letting it sit for awhile. I have changed the fuel pump, the trottle boby, the fuel and air filter, the fuel relay the map sencer, the temp sencer, the distributor.

My fuel pump seams to work when it wants to. I've rebuilt the throttle body and put it back on and the truck started back up and ran steady. I then saw a leak at the top of the throttle body and shut the truck off. Upon doing this I then removed the housing and found a bad o-ring. I put in another rebuild kit and after doing so tried to start the truck and it wouldn't start.I checked the fuel line and no fuel was pumping out. i checked the inline filter and there was a little gas in the line.
