1997 Cadillac Catera 4 cyl Four Wheel Drive Automatic 77000 miles
I have a 1997 catera, about 77000 mile on the engine. When try to start the car it wont start, it look like it want to crank up but nothing. We've check the fuel injector, the engine, the computer but the car still wont start. What else can it be, even mechanic cant figure it out.
Do below to determine if its fuel or spark problem-something has to give
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
