Hi guys, I had to pull my battery out to charge it up today,as it went flat over Xmas. So I charged it and refitted it and now my Electric Autometer fuel pressure guage has stopped working??I have checked all the wiring at the back of the guage and where I wired it into all seems good,the sender unit is mounted before the fuel rail and checked and cleaned that also.I can hear the 044 pumping off the PW surge tank just getting no reading on the guage..Is there any way of checking the guage itself??or am I up for a new guage?? I don't really want to drive it with no fuel pressure readings!! Please, any help is appreciated! cheers Ed.
