Car not starting
My car will start an unpredictable number
of times when the fuel pump relay and the
ac cutout relays are tinkered with.
I have new battery new starter new solenoid
new fuses new fuel pump relay new battery
terminal eyeloops new alternator . I have
tightened all teeth on relay boxes I've
cleaned all ground wires and tightened.
Theft prove out is good keys are good
ignition and transceiver good etc.
Any ideas? Desperate
inspect the underside of the power distribution box that has the fuel pump relay for corrosion or loose wires, also check the condition of all ground connections.
Underside looks good. Wires seem all the same and the grounds are clean and tight
Replace spark plugs if not working get new coil packs/spark plug wire/connectors whatever u wanna call it....
Possible ignition switch intermittent fault
Let me ask y'all this. I cleaned the relay box ground really good but it didn't start. I then pulled the relay and put it back in. The car has been starting ever since. Is there any possibility that after the ground was put back I kind of reset it by pulling and plugging relay back in? In other words did I fix the problem by cleaning the ground wire even though it didn't start immediately after?
Clean contacts are crucial
