    92 vr4 firing issues

    I have no fire at the coil. I have replaced the ecu, mfi relay, and coil. I can crank and crank I get one spark when I let off the key. thats it. I am going to replace the coil pack again, ptu, and cas. if that doesn't fix it any ideas?

    When i replace things I replace them with verified good parts from my parts cars. Thats the fun in having 14 or so parts cars. lol...

    I've now replaced the cam sensor on the passengers side of the rear head, the ptu, coil, ecu, and mfi relay. I think it's going to be a crank angle sensor as mentioned before. It's the only thing I haven't replaced lol... I'm going to hook up my logger and see if I can test that before I go tearing the everything off the front of the motor.

    There is no crank angle sensor if you have an engine with the all in one CAS on the rear head (intake side)

    Yep, 1992 model, no seperate cam/crank sensor, just that one unit.
