The car is not supposed to crank unless the brake pedal is pushed. My 90 is like that.
If you crank the engine and the shift light stays on (Orange with up arrow) it is most likely your crank position sensor. If this is the case, and the old sensor is physically damaged, you should replace the crank balancer and bolt. Ford's price is reasonable.
This is located in behind the plastic timing cover. It reads three pulses per crank rev. Clearance is critical and should be set with the proper Ford tool. The cam sensor is a common problem. It is located above the water pump and sticks out on an angle. The housing (black) may have the "Non-adjustable" sticker on it still. To change it, remove the two bolts holding the cover on and replace it. Be carefull, it is possible to get these 180° out of alignment in which case, it may start momentairly, then stall again. It could also be the D.I.S. module on the pass side, right on top. This is your ignition module. It could also be a faulty coil pack.
Does the fuel pump start then stop when you turn the key on? If you don't hear is buzz for a sec, then check the fuse and or relay. If this is okay, check the inertia switch. This shuts off the pump in an accident. Peel up the drivers side trunk carpeting and look in the quarter panel. You will see a black box, it's pretty small. There is a round spot in it. Try pushing the button down. If it clicks, thats a good thing as you wll now most likely have a running fuel pump. If none of that works, it could be the pump itself, which is inside the tank. You can also check the wires at the pump.
