Chevrolet Suburban and Tahoe No Start problems
Yesterday afternoon my wife goes to head out and it won't start. She tried it several times. I came home a few hours later and checked the plugs. Saw the threads were a little bit wet so fuel was getting in there I figured. After trying to start it a few times, I could smell fuel at the tailpipe. I then removed a spark plug and held it while she cranked it to see if there was spark. Yeah, not the smartest thing, but I sure did find out there was spark! Saw the spark and felt a nice big snap in my hand when it did! Anyway, tried it again this morning and still no start. So I don't think it's a flooding issue.
I also have a CompuStar alarm, but no remote start connected. It seems very strange to me that fuel could be getting to the cylinders, and spark and it doesn't fire. I located the fuel filter but it ran totally fine until this point. No sluggishness or any of that, so a filter makes no sense. I hear the fuel pump prime every time the key is turned to 'ON' position. The CEL (check engine light) is on, but has been intermittently since we bought it from my wife's dad. Ran the codes right after buying it and it said something about spark on the drivers bank so I replaced the plugs on that side. Otherwise the truck runs very well, CEL on or off. The truck has an aftermarket exhaust, MAF, and K&N intake kit on it. I've owned Dodges always and you can check the codes yourself, but I think you need a scanner for this right?
Any ideas? It's in our garage right now which is good, but I'd love to be able to diagnose it before it goes out to a shop.
