    RB20DET Down 1 Cylinder - Why?

    in General Maintenance

    Posted

    Thanks Marc & Joel. All comments taken on board.

    Marc, the last time it was running (before timing belt), there were no problems. So i'd have to think that the injectors are fine. FYI, they are 550cc RX7 ones and have been tested and only been in the car about a month.

    Joel, i was maybe thinking the ignitor module myself. As you know, you have to take the module off to get to the coilpacks, so in doing this the associated wiring to the module was moved around as well. I notice that the wiring is a bit stiff...prolly from years of heat. I'll pass this info on to him.

    Regards,

    RB20DET Down 1 Cylinder - Why?

    in General Maintenance

    My brother has just done his timing belt. It was done the correct way by aligning number 1 cylinder to TDC. The CAS is in the same position as before. Checked timing and it was in the correct range.

    Now when the car's started, it's only running on 5 cylinders. Number 1 cylinder is down (figured out by pulling the connector on #1 coilpack while it was running).

    So the sparkplug was checked and it's making spark. #1 coilpack was swapped with another one and yet #1 cylinder still doesn't fire.

    The car was running fine before the timing belt change. It has aftermarket turbo and powerfc.

    What else could the problem be and how could i go about diagnosing it?

    Any help appreciated.

    Scott
