1989 Jaguar XJS V12 wont start. It will sound like it is trying but wont turn over. I was thinking it might be the spark plugs or a fuse but upon checking those theyre all fine. It could be a few other things, but im just not sure.
Do you
have the same problem?

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, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, 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

I hear the fuel injector come on, the engines getting the gas. So it must be one of the other problems. I'll troubleshoot tomorrow and post results.
