Still the same! then I noticed the fuel pump conector had the wires crossed on the section going to the ecm. I fIxed that, the fuel pump immediately worked. However, the truck wasn't starting yet, no fuel at the tbi. Then I disconnected the fuel line right outside the fuel tank, fuel was coming out ok when I cranked the truck. I then plugged it back and disconnected the fuel line just before the tbi and cranked the truck. No fuel at all, from both, the supply and the return line. I then proceeded to disconnect each section of the fuel lines and blew them out with C02 air. Found out that the line section from the fuel tank to the fuel flter was badly clogged. I replaced that section of the fuel line, and whala! Damn truck worked! Sure gave me a headache, just glad it worked. Now it starts right away with just a turn of the key.

Thanks for the reply.

Quite frustrating when stuff like that happens but when you don't give up and just bear down and start eliminating those things that stand in the way of success it bears fruit.
Good on you.
