I have replaced fuel pump,relay and even the clutch safety switch. The clutch safety switch because if I banged the clutch to the floor a couple times the pump would kick on. That has since ceased to work. I've checked all grounds I could find. For awhile if I put my code reader in it would read error and when I unplugged it the pump would come on and if I immediately plugged it back in it would say no codes. That also has ceased to work. Any next steps out there ?

 

it could just be the ecu, i would swap in another ecu

banging on the floor might shake the ecu enough to get it to work
