Re: PCM Solenoid Fuse

Anthony,
I would check the fuse on the PDP to be sure it is still good. Visual inspection may not show an open so use a meter. Replace as needed and be sure to get it installed so that it is only about 1/8" above the PDP surface. This is tricky so just be patient. Then move the jumper on the PCM for 12 volts. At 24 volts, the solenoids might fire but the current is usually double what it is expected at 12 volts. In some cases solenoid damage may result.

While we are talking about fuses on the PDP. I have seen some teams modify the PDP to allow different fuses. This is not a legal modification. See R66 for further info.
