Here my problem i had rear injector on passangers side leaking from o ring failed and it pouring gas out like crazy i drove it like this for about four blocks then the truck bucked and died will not start up the engine cranks over with no problem and the fuel guage doesn't move at all when the truck died it had a little more than a quarter of atank of gas in it i can't find the fuel relay or fuel pump fuse i looked in the fuse box for the fuse and relay but the spots listed doesn't have a fuse or a relay in the spots where the diagram said it should be can anyone help me diagnose the problem and maybe explain how to fix it properly thanks in advanced

Can you hear it prime when you turn the key on??

You can try banging on the tank while someone cranks it over to get the fuel pump turn on aswell.

I would assume it doesn't kick on at all if the gauge never budges. Sounds to me like you gotta drop the tank and likely replace the fuel pump. I was able to fone a fuse diagram online that may be useful to you... Could be what you were already looking at though.

No sound when key is in the ignition no movement of the fuel guage either so I'm hoping that a fuse or a relay burnt out from what i can from online the fuse and relay is under the bed but i haven't been able to crawl under and look yet

Have you tried adding gas to it?

No do you think that will do something

How much i don't want to add too much if i have to drop the tank

I mean, put in 5-10 gallons to make sure its not actually empty.

If that doesnt fix it immediately, put a pressure gauge on the rail.

I will try it but before it died it red a quarter of a tank i had just put gas in it when i was done fill it with the amout i bought it red 3/4 full i dumped about a half tank on the ground

So how much is in there now? I would still add 5 gallons, its only like 30lbs. Pulling the bed is easier than dropping the tank anyway. If you have someone put their ear to the tank can they hear the pump turn on?
