Re: 90 XJ Won't start low (15psi) fuel pressure
Well it was a loose hose at the pump, I now have 36 psi and it holds
for hours but the darn thing still won't start, everything is hooked up
right. I did a full tune up and changed the CPS and it still won't
start. It does fire a few times but thats it, any suggestions?
