Electrical problem
2000 Ford Mustang 6 cyl Two Wheel Drive Automatic 150000 miles

My car will not start. We tested the battery, alternator and the starter. We replaced the battery terminals. What else could be the problem

Do you
have the same problem?

Pick your symptoms and get back with some testing results

Cranks but no start condition:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 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, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing

No crank at all/nothing/nada:

Could be the starter, starter relay, park and neutral switch/clutch switch and ignition switch assuming the battery and connections are good
