So I have it narrowed down to two possible problems, both of which are unlikely in my opinion. So I turn the truck off to fill up gas. Fill the gas up, get back in. Turn On, try starting. Nothing. Go under hood see my starter relay is busted. Walk to the awesomely close advance auto parts, buy new one. Replace. Starter turns over, but truck doesn’t start. Now, on the starter relay before, one of the connections was missing. There was 4 connections, one for battery, one for starter, one for starter switch, and one that says ‘I’ which i honestly don’t know what its for, I assumed it wasnt needed since the starter relay before didn’t have it connected. Now, unless my truck is just being a bxxxh and wanting more new parts, I think it might be that connection screwing me. It started fine a couple of minutes before i turned it off for gas and only drove maybe a 1/4… it almost sounds like either the alternator is out (haven’t checked to see if spark plugs sparking yet), or that the fuel pump isn’t working which I hope to god isn’t the case because I filled my tank up and I heard the pump is inside the tank. So now I am taking the bus to work until I can get my truck fixed. Any ideas what is it? Could it be that missing terminal on the starter relay?
Edit: not sure if both tanks have seperate pump, but my fuel tank switch is broken so I couldn’t switch it over to see if other tank works anyway.
