    it is solenoid electrical fault

    may be corroded connector, may be wiring, may be bad solenoid

    check all this stuff

    the solenoid under the valve cover is VEB (jakes) solenoid.

    EPG silenoid is mounted on cyl blosk, driver's side near bellhousing, it is on frame rail level.

    Solenoid may be damaged with oil, that leaks to wiring harness throught the rubber grommet in point were wires come under valve cover.

    the one on the frame with an air line going to one side and a 4 or 5 electrical plug on the driver side left.because I replace the one next to starter avu or air vale is that the one or is there also a solenoid next to the air valve.this problem started when I was replacing the starter and hot cable touch the frame.it burn a couple fuses ecm#81 and #15 radio try to see if there was any relay or fuse for epg solenoid and could not find any .I replace all my relays to see if it will solve it and nothing.

    ouh..... can you find EPG? it is on turbo. Look where air line from EPG goes (8mm) and you find solenoid
