No Power
I try cranking my car after a few month n it wont start. Change two different main relay n still. Ecu have no power. Check all ground n it seem fine . Anyone got any ideal where to start. Would a harness go bad.

Re: No Power
Things can go bad anytime.....Bypass the ecu power from the harness and run new power wires from the battery to ecu..... if it works time to start chasing a power issue...
Does the rest of the car have power ?

Re: No Power
Everthing have power. Ecu relay n pump have no power. But if relay dont have power it wont turn the pump or ecu on

Re: No Power
So ecu has no power? Can be verified by checking a 5v reference at tps sensor when key on, if there's no 5v ref there then ecu isn't getting power, check voltage at fuse box under the hood ELD fuse to ecu there should be 12v there if not then fuse box is most likely to be the culprit
