2003 Hyundai Sonata has no power to fuel pump. Fuse is good, relay has been replaced.
Dam roy don't you think it could be the safty fuel shut off switch? I am not sure where that is located at in this model but new relay and fuse is good if every thing else is working wtf. That is where I would start. I know connections are a good place to start.But if there is power every place else why do you think bad connection?
the ASD relay~
cannot find the ASD relay...these are found on high-pressure systems...also could not find the fuel pump relay that would be the number one cause...this is an external "kielbasa" fuel pump (not made that way anymore on account of flaming rollovers and lawsuits)....take your small battery charger and apply 12 volts....if the thing goes whirr-whirr there is a problem with positive power to the pump...or grounding~
suspect system ground needs to be cleaned for this electric pump to operate properly...grab a coarse wirebrush...undo the 1/0 cable connection to the chassis...wirebrush the spot where it bolts to...wirebrush the lug to restore proper ground to the fuel pump...this will fix yer wagon~
wouldn't it be nice if there was a "red reset" button?
