Why won't truck accelerate and why does it now sift 500 to 1000 rpm higher than normal?
I replaced fuel pump and when I went to start truck it ran for about 20 seconds and died, it did that three times and then would'nt start anymore. I towed it to shop. They said it was the dist. When I got it back it ran but I had no power, shifting is now about 1000 rpms higher than it should be, power locks no longer work, and if the truck even sees an incline it starts slowing down. Before changing fuel pump the engine ran great. My scan tool said the ECM was in limp mode but the engine never ran better. Now, after reman dist. Ha sbeen installed (by shop)I I get code 42 Electronic sparks advance and ECM in limp mode. I installed a reman ECM last Thursday but I still have no acceleration above 30 mph. I sure could use another opinion, that is if any of this makes sense to ya. Thanx
have the same problem?
