Change, or look for the wires of the crank angle sensor (this is in the left side of the cylinder head, connected to the camshaft) |

I have looked at that there is no power coming to that either car was running switched it off and refused to start again thats how i discovered the problem with spark and injectors no fuses gone no sign of broken wires when i crank the engine the coil gets power for a split second but then nothing its baffled me |

If the check engine light doesn't come on then it's ECU related. Maybe you tried a second bad ecu? |

It was running when i replaced the ecu it was a recon thats why i cant figure it out i turned it offf and it wouldnt start again its a weird one if i open up the mpi relay and press the contact the engine light comes on but stays on |
