Hi my name is***** will try to help. Check for a faulty pressure switch or the harness for damaged wiring or connector pins. Check all your fuses and relays as well. If this does not uncover your problem you will need to obtain a wiring diagram through teco for your model and serial number to get more involved in testing out the circuits with a digital multimeter to isolate the problem. Let me know
Hi Did you get this resolved?
