Unplug it at the tank and jump it there, if it works you have a wiring problem. If id does not work you need a new pump.
"he said he had to "modify" some wiring at the ECU."
Sounds like you found the problem, see what he "modifyed" and fix it!!!!
im not getting any power to the plug. the problem with the modified ecu is he doesnt remember what he did.
