Need help reading GP oHm test results...
The truck has been struggling to start all winter without it plugged in. First start in the morning has been a struggle. It will always fire after about 7 seconds of cranking. So i got around to running some tests..
Test 1 - Glow Plug Relay - tested good (12.5V from the battery, 11.5V to the GP's)
Test 2 - oHm test the relay (key off) GP are showing 0.5 (RED FLAG)
Test 3 - Pulled the connectors on each valve cover and tested each prong. Below are each prongs results in ohms.
Front of Truck
My question is does each prong correspond with each GP/Cylinder accordingly??? I might just replace all the plugs since I'm in there. I plan to do a 50 Cent mod while in there this time. Do you recommend changing out the Harness as well?
Your guy's advice is appreciated! Thanks.
