I'm getting a code for glow plug Circuit "A". intermittent -
after glow up - engine fires right up, less than 1 revolution.. but often a get a code.. can clear it.. could be 3 starts or 3 days...then back.
With respect to any help I get here... Now before anyone goes into telling me to check my glowplug connections and all the other stuff... please at least read the post.
There are new glow plugs.
wiring has been checked - the harness is good - that i know of... connectors are good
New glow plugs. replaced engine - did I say new glow plugs!
Now..
if anyone knows which circuit would be circuit A so I'm not barking up the wrong tree...
is it limited to right or left side.. ( driver or passenger side) to further double check and trace wiring for a break or something intermittent.
shall i be looking at the glow plug relay? a specific test?
Has anyone had a similar issue with a glow plug circuit gremlin.
Will my scanner OBD-2 .com scanning software tell me voltages "live"
If using a scanner.. do you scan during the start up process?
or scan with the glow plugs fired up only?
I know there are a lot of "if's" in here, but wanted to give as much detail on what I have for resources and then where to look.
no disrespect but I think sometimes, people know the drill for first steps and often list them out in order to help us "new guys" ..
I've been around the block on this truck... just going on a road less traveled!
respectfully submitted...
