So, I have a 2010 Nissan Titan SE that refuses to start. Took it to my mechanic and after an hour of looking around, they assume it's the ECM. My question is, after doing loads of research on here, do you think it could be my ECU Relay going bad? I know that's something that has been common with Nissan's in the past. Would the ECU relay prevent my truck from starting? As of right now my truck turns over but doesn't start. It's not the battery. I'm just hoping it could be the ECU Relay not my ECM or my IPDM. Knowing my luck, everything is wrong. Anyways, thanks in advance for your help!
