First things first I went to a Chevy forum, go figure no help. I outta go to my DSM boys.
Here's the deal:
I am having a ton of trouble with this truck. 5.7L k2500 automatic. Last summer, the truck got a high idle, around 2200 RPMs. I never had time or the tools to fix it as I am in school and I only drove it to work. On a weekend that I happened to travel home, I got caught in a traffic jam and I believe the transmission overheated and the torque converter was slightly damaged because I was laying on the brakes while it wanted to maintain 2200 RPMs.
Once the transmission heated up to normal temps, driving on the highway, it would downshift to 4th as if the power wasn't getting to the wheels in overdrive.
Please note, this transmission failure occurred during the time of the high idle. The high idle is still a present issue with the truck.
So I picked up another truck for the time being and towed my Chevy back home to avoid more damage to the torque converter. However, in Columbus (location of school), the truck wouldn't start to drive it up on the trailer. I got a can of starter fluid and drove it up the trailer that way. I didn't really have a choice as keeping a vehicle on city streets near campus requires a parking pass and it was towards expiration and end of the school year. I didn't want to deal with 2 vehicles in Columbus as well.
A couple weeks later I make it home and I take a look. No start. Engine turns over. I cannot hear the fuel pump. I ended up replacing the rusty tank and the fuel pump. Go to turn it over and it starts right up (don't forget its still idling high). I drive it around a bit and pull it back into the drive. Good to go, issue one down.
My father calls me a couple days later saying the truck won't start. Long story short he tows it to the shop because I don't have the time and/or money to keep driving back and forth from school to home. He tells me later on that the shop claims the new fuel pump we installed was bad. My father explained how it was probably a bad connection to the pump; but, he bites the bullet and tells them to install a new pump.
Today, my father explained how the shop installed a pump. The truck started right up. They shut it off. They go to start it again and it doesn't start. He said they even "spliced" the connections better... replaced the fuel line... and the same results... they even put in another fuel pump assembly (total of 3 new assemblies). Fortunately, they didn't charge my father, but they said they couldn't fix it.
Does anyone have a clue what's wrong with it? I have a feeling it's not worth it to invest more money into it... any idea would be great.
I have a feeling it could be an ECU issue.
