i jump out the relay and made the fuel pump run for a long time and it started and run , turned it off and no start again took the plugs off the pcm and reinstalled them and it started and ran waited a few minuets and again no start , so i am going to start with 2 new relays and go from there, thanks

Did you utilize the dialectic grease? With the smaller than normal terminals that this particular relay has, any moisture in there would cause issues. I’d be tempted to replace this with an automotive style relay setup with normal sized blades. They will be more robust than what your using currently…

Well, multiple threads about the same thing won't help fix the issue because we are going to read them and wonder why there's another thread about the same thing.
It we're not good enough here on these forums, might want to find someone local you can get in person.
