I was driving on the beach one day and the truck cut out and off. Through process of elimination I found that it was a fuel problem. First I checked the lines and found some kinks and a crack but no leaks and didnt hear my pump running. I had to buy a new gas tank when I went to install my fuel pump because of rust. The lines from the sending unit actually broke off when I dropped the tank because they were rusted so bad. I of course installed a new sending unit also. I found that my fuel pump fuse was blown so I changed it. One of the guys with me when it happened decided to cross my wires before the fuse to do a " smoke test" and then shorted something deeper in the system. I created a temporary alt. Hot to the pump to isolate where my problem was and the pump would run and the car would try to start. I sounds like its not getting enough fuel pressure at the TBI and when I watch it come out of the injecters it doesn't seem to spray the way it should. None of the lines leak, and when I bypass the relay the fuse doesnt blow. What does the relay do and if it is bad would that be the reason my pressure is deficient? Is there a certain hot that pressurizes at the injector plugs on the TBI? Does it make a difference if the injector plugs are switched?
