My car is continually getting hot. I have replaced the water pump, radiator fan, thermostat,…
Engine ignition trouble. My Holden Vectra was working fine and suddenly all electrical system failed. After replacing the battery and making sure all cables were connected properly I checked fuses in engine and under steering wheel. I put the key into the ignition and it only switches on the ignition dashboard lights but fails to turn engine over and start. Is this a problem with the immobilizer or is there a simple way of fixing this? all the locking works on the remote etc.
I may in fact be the aftermarket immobilizer. You can check for battery voltage going to the “S” terminal on the starter while someone holds the ignition key in the “START” position. If you see battery positive, replace the starter(this is assuming all ground connections are good). If you do not see battery voltage trace through the Neutral switch back to the ignition switch.2001-pontiac-grand-am-starting-charging-starting-circuit-1-of-1
