Ok, I thought this was a strange unique issue until I performed a search on here today: wts light flickers contstantly and no start
Anyway, my truck started this a few weeks ago but it wasn't so bad. I could cycle the key off and on a few times and the glow plug relay would hold in and the truck would fire off fine. I even swapped a couple of the relays under the hood and thought that was it, it at least seemed to help anyway. So this morning I was going to drive it to work (not my daily driver anymore) and it starts the flickering, after a few cycles the WTS light holds and she fires up fine. I realized I forgot something in the house so as I was going back to the door it dies, sounded like someone just cut off the key. Now, the WTS light will ONLY flicker, engine turns over fine, no start. I swapped different relays around and no change. I've read that the PCM controls the GPR, isn't this where the performance chips are installed or is that the IDM module?
I was also reading that some people experienced this issue after changing programming. So I guess my first line of attack will be to remove the old chip that was in the truck when I got it a few years back and see if this corrects the issue. If not, then I guess I'll replace all the relays under the hood. After that I guess checking wiring connections?
At any rate, I was really optimistic as to finding someone that has had a similiar issue and found the problem on here, but there seems to be a bunch of threads with no answers to them. I hope mine is different
I WILL fix it and post up what I find. Thanks in advance for any help. I haven't done anything to it in a few years and have forgotten some of the terms and acronyms since it hasn't given me any trouble in so long. HA!
