So I'm a well knowledgeable member by this time, I've assumed it was the IPDM relay immediately, symptoms began 2-3 days ago. It wouldn't crank the first or second times but then it would fire, this morning I went to go to work, no start up at all. I didn't have time to look at it, I had to be at work... so now I'm trying to replace my relay with the one I bought from Robkar last summer at the Cali Titan meet, my question is... Is the IPDM relay suppose to be green? It's the only one that is green, I popped it out and replaced it with my replacement relay and no truck start up, I'm about to go try swapping the fog light relay with the ECU one now and see if my luck gets better...
