Ignition on warm up issues
On my trip to Bowling Green last week, I started having an issue with my truck popping multiple codes after I start up.
They are all dealing with the warm up at start. Glow plug circuit, manifold warm up etc. There are between 4 and 6 codes.
My wait to start comes on, but I noticed that my voltage was not dropped from the glow plugs drawing current after the motor was running. I would normally see a voltage around 12.4 or so for some 25 - 30 seconds and then kick up to 13.8V.
I have a GP solonoid in my Excursion like a 99 F250. When I looked this part up, the books show a module for my 2000 EX, and I am not equipped with that ONLY at least.
I have not checked the solonoid yet for signal to to activate it, but will try to later when I have time. I was looking for ideas of anything else I may need to inspect if it is not getting the signal to push power to the glow plugs.
I clear the codes right away and no others codes will appear until the motor is shut of and started again. The CEL comes on about 4 seconds after ignition fire off.
Thanks in advance for any help,
