yeah i can see that hahaha but once mine got started it shut off.. i cranked it for another 15 seconds and it fired back up and was EXTREMELY inconsistent but then smoother out after 5-10 minutes and i took it for a test drove... and about 5-10 miles later everything was working pretty well BUT for the first week it started VERY hard and took a couple seconds of cranking to fire it up... but most of this is cause i did a fuel pump along with injectors, blowing out the cylinders, and doing GPs.....

UVC's are the under valve cover gaskets. Attached ti the gaskets via plugs are the UVC harnesses that have individual plugs that feed the GP's and the Injectors.

Both the male & female plugs need to be carefully inspected for shorting, damage and burning. The plugs that plug into the top of the UCV's also have both male & female sockets. They too need close inspection as to damage and burning etc.

If you really want to be through check all pins and sockets as well as the leads going to the GP's and Injectors. On those plugs there are five (5) pins #1 & #5 are the GP's, #2 & #4 are the injectors and the center pin is the common ground.

It's a tedious process but it usually pays off in the long run. It just does not pay to take short cuts.

Ok so let me make sure I understand what is going on. The truck was hard starting so you replaced the GP's and relay. Then you tried to start it but it wasn't any better?

If that is the case verify that both large posts on the relay have battery power when the key is first turned on. then test the GP's and UVC's how I descibe in this post.
