this morning on my way into work my truck would started to cutting out when traveling up a grade or taking off from a red light not sputter but quit until I let out of it didnt do it everytime but probably 7-8 times on my way in to work and this is the first sign ive had of it. what could it be?? I was thinking maybe lift pump but then again im no diesel mechanic either

 

Do you have a fuel-pressure gauge on it ??

A gauge would be a big benefit in narrowing down what is going on.


The injector-pump is capable of drawing fuel through a dead stock-type lift-pump with the driver being none the wiser; and, many have driven around for years, not knowing their lift-pump was completely dead.


Without any gauge readings to tell me otherwise, I would change the fuel-filter and see what that did.

 

bearkiller how is the fuel pressure gauge installed is a gauge from the local parts store okay

 

Any gauge that says *** pressure will work, like an oil pressure gauge. Tapped into the banjo bolt on the outlet of the filter.

But like Bearkiller i'd throw a fuel filter on it and see what happens, if that doesn't help than a lift pump.

 

thanks for the insight heading out the door to autozone

 

well changed the fuel filter and it did it on me and the water in fuel light came on after changing the filter and repairing the wires coming out of the water drain sensor not sure that the wires were actually a problem but had to bare spots
what now

 

Next thing would be, as mentioned, get a pressure gauge on there and make sure that your fuel supply system is working. Any gauge, 0 to 15, 20, 30, 40, whatever psi, will do. Plumb it in some where after the lift pump.

There are a lot of fairly easy to repair things that it could be. Such as: bad lift pump, bad fuel lines, clogged strainer in the fuel tank, bad suction pipe in tank, I forget the rest, somebody else will remember.

How cold is it where you are at?

Good Day,

Check the wire on the shutdown selonoid. Mine did he same thing the plug was kinda just sitting against the terminal and everytime I got on it it shut off cause the wire was pulling back. Then when I let out it would start right back up.

 

I took the new fuel filter off and strained the contents and it was already full of corrosion particles. dropped the tank and the bottom of the tank which by the way is only about three months old is full of junk so i strained all of the fuel out of it and low and behold its also got a very high water content the whole problem was the filling station owner is watering his fuel down somy water in fuel light does work correctly going to try and put a pressure gauge today. what range should i be in

 

NEVER buy fuel from foreigners.


For a stock-type lift-pump a 0-16 PSI is a good gauge; for a piston-lift-pump a 0-30 or -35 is about ideal.

If you have any notion of switching to a piston-pump in the future, just go ahead and get the 0-30.


The gauge doesn't have to say "FUEL" on it to work.

Any pressure gauge will work; all of the fuel-pressure gauges on my trucks say "WATER" on the face.

I can buy the same brand "WATER" pressure gauge for about 1/10 the price of the one that says "FUEL"; they are exactly the same gauge with a reversible face; one face says "WATER", the other says "FUEL"; they charge according to which face they turn to the front.

 

Im having the exact same problem. Im going to post the link to my thread so that hopefully between both of our threads we can find a answer.

If you would like me to remove the link just let me know and im sorry. Keep us posted if you find the problem.

Thanks

Well i spoke to soon even though the diesel was junk that i bought it eveidentally wasnt the whole problem. Drove the truck yesterday afternoon and it startedfalling on its face again and now its more frequent, were is the fuel shutof valve, solenoid located so i can check the wires??

 

On the top of the pump head.

 

Top of the pump. I hear the best thing to do is change the connectors to ring terminals instead of the slip on connections.

Chris

 

there is two slip on connectors correct one is facing toward the driver inner fender and one is towards firewall, am i on the right part? If so i can see were the one slip on connector has slid on its post and the other slip on post facing firewall has no wire on it looks like metal wear on the post but couldnt locate the wire, If I am in the correct spot and the wire is some how missing is there a schematic were i could trace it down.
