Unfortunetly I don't have access to a scanner, but got it to the shop the took it in and the said it corrected itself. They still scanned it, but said it was a slight emissions leak or the gas cap.

Well went to get Gas and my Wife noticed there was Gas leaking. I crawled underneath sure enough it's leaking and not from the fuel stem either. So, back to the dealership we go. They gave us a nice 2001 Jeep Gand Cheereke though.

Probably the gasket from putting in the Fuel Pump or like jigger said the front vent.

 

Ok, your are going to Love this one. Went to the Dealership this morning turns out that the filler tube wasn't seated back into the Gas Tank properly, so consequently when I put Gas in her it would go straight to the ground. They actually pulled the Gas Tank down to find the problem (good Dealership for doing that, as they should). After it was fixed the guy took it down to put $20 in Gas to make sure she didn't leak, sofar so good.

The guy I was talking to was funny, he's like yeah someone is going to ketch H3ll for this.

Here's the thing though, this whole situation has left a bad taste with me and I'm not so sure I want to do anything to the Blazer other than the Usual Maintenance, needing tires, oil changes, etc... I'm just not sure anymore.

Take Care.
