92mustang510

Ok i have bought a 92 lx hatch and it had the comp hangin out of the kick panel and a extra in the back the car will start and then when it gets to runing temp if i turn the car off and back on the car dont wanna start unless i pull the fuel pump relay and then plug it back in. could this be because the comp is not the right one or that the comp is going bad or what. i have tried a new relay for the fuel pump and same problem i have tried a new ignition module and same problem. do the comps vary alot year to year? any info will help

your best bet is to tell us the model on the computer itself...

a9l,a9p,x3z... etc

I doubt this isa 'computer compatability' issue...

However, do tell us what ecu you are using.


Stay focused on the fuel relay... that does sound to be the culprit...
