WTF is going on with my rig? *Update - Fuel Pump*
So we just drove out to Cali from Denver - left Friday night, stayed in Henderson (SE Vegas) for a night, then drove the rest of the way to Oceanside on Saturday. On saturday afternoon, I'm on the 215 heading South, and all of a sudden my truck loses a shitload of power, like the engine is pulling a TON of timing or something. It downshifts into 3rd on the highway and stays there, and kicks the SES light on. I pull off on the next exit and into the gas station, and it's running super rough - worse than I've ever heard it. I'm down to about 1/4 tank so I gas up and let it cool down for about 15 minutes. Start it back up, starts a little rough but runs fine the rest of the way down to OS.
The SES light is still on, and it starts a little rough each time but runs fine overall. What gives?
Come to find out that my father in law's 02 suburban with 195K on it was doing the same thing, but to the point that it downshifted into 1st, then completely died on the side of the highway. They let it cool down for about 10 minutes then it was ok. My FIL said that it was vapor lock...but that doesn't make any sense to me. I thought that vapor lock was damn near impossible to get with fuel injected vehicles? I'm at a loss. Next step is to run it to the local dealership and find out what the hell the code is, and what I need to do to get it back up to par. This is pissing me off, I've taken awesome care of this truck and it's always run like a top...now this random crap. I guess at 109K, something's gotta give, eh?
