Why do you believe that you need a fuel pump relay?

thafox

I hook up power to the fuel pump it works, fuses r fine, I've got good spark everywhere just not gettin fuel when crankin...also I hookd up the pump 2 a switch temporarily an it started up everytime I hit the switch 2 turn on the pump

The system is not the same as a 12a engine. The circuit goes thru the AFM and main relay. It also relys on the trailing ignitor for power. Does the tach work when the engine is running?

thafox

Yes tach works fine throttle response is same etc

Pull the fuse marked engine in the fuse box and "Replace" it with a known good one.

thafox

U mean the under dash fuse box correct?....I've checked those prior and were fine, also switched the fusable links around with know good ones and still the same thing
