Ok, so I have replaced the main relay with a known good used one, it clicks now, but still no fuel pressure. I can run jumper wires to the pump (out of the car) and it runs. What the hell else is in this circuit? I am beyond perplexed. This is on my dad's 168k miles daily driver, no mods at all, so any advice will be much appreciated!!!


Thanks for reading....

 

Have you verified that the ecu is good ?

 

No, I have not, have you heard of an ecu doing this before?? I guess I will have to try to source an ecu to troubleshoot it....shit.

 

wires bad, bad ground

 

like nando said above could be those.. check all your fuses, connections, check for burnt wires .. theres alot of stuff it can be..

 

thanks guys, i will work on this as soon as i get a day off work! appreciate the help.
