97 Ford Probe GT not starting
WARNING: Risk of Electric Shock
Check your spark plugs and wires yourself. Remove one sparkplug at a time from the engine block, plug the wire back on, place the sparkplug on the engine or vehicle body so that the outer thread of the sparkplug would touch the body, or engine (GND) you can secure it with a cellotape or so. Turn the ignition key to the START position and when starter is spinning wach for high voltage sparks appearing between the body,engine or gasket and the tiny black end of the sparkplug called electrode. If there's a sparks, than it's fine, othervise try to get one working sparkplug and to retest this. If now it works then your sparkplugs needs to be replaced. Othervise check the resistance of the high voltage coil primary windings. this should be something between 0.2 and 10 ohms, when coil is disconnected from vehicles wiring. I just do nts remember the exact figure. If multimeter doesn't show anything, replace the coil, otherwise check if the supply current is flowing to the coil plug when IGN is ON. If it's fine then check the COM line at the same plug, using analog muldimeter is the easiest and not harmfull way to do this. If COM isn't comming You might need to go deeper into ECU, or even to replace it. If COM is fine then it would identfy that coil itself is faulty.
Update me about your progress
