The only way to narrpow down problem is to follow chart below. Its a guess otherwise. I have seen pickup coils go bad many times even if the seem to test ok vs a new one. Any time we do module, we do pickup coil. You will have to follow chart with DVOM. ( meter) It is always possible the problem does lead to a bad computer (PCM)

To test pickup coil, probe the 2 wires with meter set on Ohms. You should have(NNN) NNN-NNNNohms
