two wires is for a rheostat, your fuel lever sensor.

there is a few places that can cause a leak, on the bottom of the fuel filter there is like a 16 point plastic nut, that could be loose or not right enough. be careful though, it has plastic threads.

or the water drain valve, or the bleed screw not working right. hell even the fuel filter could not be on tight enough. loose lines, or schrader valve could cause leaks.

you can prime the system really good, and then get some soapy water and spray it all over the place and see if you can find leaks

yes i figured as much on that but it was silly that even gm with the vin claimed it as a pump

i will try that in the am and return , thanks so much , ill have me or one of my crew recheck the fire dept work on this thing tha:s:nsk

where you located

southern illinois

another issue, soemtimes the fuel filter can be accidentally be missing gaskets, or double gaskets.

i would also remove the edge too

and pump that primer on top of the FF untill its rock hard

yes i am aware of that as well ill be checking or one of the guys will in the am but i think the no start was before the filter was installed , then they tryed a filer

hmm...

any smoke when trying to crank, or fuel smells?
