crank it over, does the tach move? If it dosent your ignition module is fried.

If it does, check to see if you have fuel pressure, There is a schrader valve on the fuel rail next to the thermostat housing, depress the pintle and see if fuel shoots out.

Pull a plug and lay the plug on the strut tower, so it grounds to one of the three strut bolts. reach into the car and crank it over while looking at the plug, do you have spark?


If you have a tach that moves when you crank it, pressure at the fuel rail, and plugs that show spark, and still no start you have a serious problem.


If the tach dosent move, look for a thread by doug chase on replacing the ignition module. It covers the whole thing.

If you can hear your fuel pump running and it isn't making any weird sounds or running intermittently it should be fine. If you don't see your tach moving when you crank the engine over you most likely have a bad igniton module, if it is working then you have a problem with either your ignition coil or the distributor coil. If it isn't the coils then it could be the ECM. As usual, you should always check your fuses first to see if any are blown, then check for faulty components.

that sending unit will never read perfect even after you R&R it, mine is pretty good but it still has dead spots in it. , the whole design of them is junk.
