I have a 95 F-250 with the banks big hoss kit. This past weekend I hauled a car trailer about 300 miles with no problems, got home, filled up both tanks and all was good. Yesterday I started the truck, after Idleing for a few minutes I drove for about 500 feet and it just died like I turned the key off. It'll crank forever just wont start. I removed the fuel filter (which is brand new) to make sure there was fuel and there was, but after reinstalling it I noticed that neither fuel pump sounds like it is running. Where is the common thread between the two pumps? both were working yesterday so I doubt they both went bad at the same time. Also I noticed a relay to the left of the fuel canister had gotten so hot it melted some of the wire insulation on the connector, is this just for glow plugs or something else also? I need quick help, I gotta have my truck up and running soon, any thoughts or ideas are really apreciated.

does your tach move when you crank?Any smoke out the tail pipe when cranking?Have you checked your oil level(HPOP level too)?

 

x2 on what ron said and FYI your truck has a mechanical pump so you will not here and fuel pump sound from either tank.

 

The fuel pump is manual so i dought u would hear it running over the sound of the engine. But easy way to check that is to pull the fuel filter and turn the truck over and see if its pumping fuel in the fuel bowl.
But it sounds like what happen to mine, i was out playing in some sand then went and shut it off and she wouldnt start. It ended up being a few blow injector o-rings, which are easy to fix. So u might want to pull a couple of them and see how they look.Im not to sure about you melting problem though. someone else wil be along shortly. Oh how many miles does it have on it? oil level?

 

If you have melted wires fix them. What are they from? It sounds like they are from the glow plug relay.

Check the connections that plug into the valve cover gasket.also. they tend to melt sometimes.
If the wires are melted at the GPR then it would be hard to start the truck if it were cool there. Check that.

 

well, I did try the fuel pump test while the fuel filter and lid were removed and when the key is turned on the filter canister doesn't fill up. I didn't check the oil level but it was just changed before the trip. The hpop level? what is taht and how do you check it? If the tack does move it isn't noticeable. and yes there is a small amount of smoke when cranking. Thanks for all the help. Keep the Ideas coming.

The fuel pump is mechanical, it has a plunger in the bottom that pokes down through a hole in the top of the motor and rides on the camshaft. It only pumps when the engine is turning. Check your fuses and oil.

 

You've got a manual fuel pump, meaning, it doesn't work unless the engine is turning over, or running. The HPOP is that rectangle box on top of the engine, in front. It's right behind the fan belt, right on top. There is an allen head bolt on the right side of the box, directly on top, that can be removed and the oil should be around 3/4 of an inch from the top. If the tach ain't moving while cranking, I'm thinking the cam positioning sensor.

 

X2..you would be able to notice the tach moving,CPS sensor takes about 5minutes to change...its on the front of the block(easy to get to from under the truck..10mm bolt)....I dont have the P/N here...but it is about 25.00

buy 2 and keep one in the glove box

 

I agree CPS. Dealer has them or most parts shops.
