I've been searching so forgive me if this sounds familiar.
I was on my way home from the airport last night on the I-10 here in Phoenix. I was doing 70mph and suddenly, without warning, I lost the engine RPM. I mean the engine, with no sputter typical with running out of fuel, simply dies.
I get a tow home and start going over everything I know. I check obvious stuff like fuses, battery, and oh yeah there is fuel in the truck. I pulled the battery, put it on charge for an hour to give me a good battery to use. I run a lead from the positive terminal to the fuel pump test wire (looking from the driver side it is on the left). I listen and hear the fuel pump running. I get in...start the engine...it runs for 30 seconds then dies much the same way as on the freeway.
In the glove compartment there are three relays, one of which I believe is related to the fuel delivery system. I switched a couple around, and try to start...no go. I switch them back to the original way they were and nothing. I run the lead to the pump test wire again...this time...no buzz from the fuel pump. I gave up for a few hours, went back and it started again, ran for about 30 seconds and dies again.
I am at total loss
as what this could be and would like some pointers on where to start to eliminate systems from what could be causing this. What is sad is that this truck has been running well for years and I have been keeping it up with regular maintenance. I am going to be disappointed if I am missing something silly like a fuse I am not aware of.
Thakns for not flaming me and any help you may be able to give.
