Does the model of the pcm you put in match the one for your Vin number, if not and you just put it in you will need to get it reprogrammed. What caused you to change the pcm?

Someone please help i have a 1997 f-150 4.6 liter engine i replaced the crank sensor and the pcm the pcm is flashed and calobrated so it should be starting the scanner is not able to read any problems plus...


HAve you checked fuses? Pull them out and look at them. If good replace them. This procedure takes care of corrosion problems also. With the key on you should have one wire with battery voltage. B+. (sending a diagram) The other wires are grounded out by the ECM. per the crank sensor. The ECM grounds out two cylinders at a time, one on the compression stroke(fire) the other on the exhaust stroke of another cylinder. You having NO codes would be abnormal. Since you have no start conditions. I'm sending you a diagram, and pin outs for the ECM and the crank sensor, and the coils.

Does a 1987 Ford, 302 have a crank sensor?


Hi Brad,
That unit does not have a crank sensor per say the PCM is told where #1 cylinder is by a short air gap in the Distributor that goes by the Stator and that tell the ignition when to fire. I hope this helps you Brad!!!!!

you don't have crank signal to fire your plugs is that what you mean if so check for correct power going to sensor and if hall effect or magnetic generating signal sensor in order to determine the proper testing procedure

Location of ignition control module


It does not have an ignition control module.
The electronic ignition (EI) for the 4.0L engine consists of the following components:
Crankshaft position sensor (CKP sensor) and 36 minus 1 tooth trigger wheel.
Ignition coil .
powertrain control module (PCM) .
Related wiring.
The PCM controls the firing of the coil based on the signal from the crankshaft position sensor.
The crankshaft position sensor (CKP sensor) is a variable reluctance-type sensor, triggered by a 36 minus 1 tooth trigger wheel configuration machined into the rear of the crankshaft vibration damper. The signal generated by this CKP sensor is called a CKP signal. The CKP signal provides the base timing and rpm information to the powertrain control module (PCM). Base timing is set at 10 degrees BTDC and is not adjustable.
If vehicle has no spark then turn key to on position,check engine light should come on.As you start cranking engine it should go out while cranking after about 10 secs. it should come back on(while cranking). If it come on then the PCM sees the signal,if it does not then PCM is not seeing it and this is your problem,either the CKP sensor or the wiring to it.
