KENWORTH T2000 no power on uphills.?

Question

2003 KW T-2000. The RPM's drop when i'm going up hills and the Turbo stops working and then it starts Working after I press the gas pedal 4-5 time. I had the air charge cooler replaced and the turbo checked for damage but no damage. and it looses power only when i'm loaded. and to make it worst the fuel lines doesn't have a hand pump like the other trucks do. And at the same time the guages like to go crazy every time I go over a bump. they work when i go over a bump and they stop working when i go over a bump.. but the main problem is when I loose power going uphills. the computer shows no errors. the turbo stops and it gets very quite and then it kicks it agian.. anything would be helpful i had every repair shop tell me they can't find anything wrong with this but then it does it agian.. Please help me before i kill myself

Answer 1

Sound like there may be a loose connection causing the waste gate on the turbo to remain open. Check the plugs on the firewall & engine. If unable to find anything then may have take it to Cat, Cummins, or Detroit & have it diagnoised

Answer 2

try starting it from a clean bucket of fuel, let the pump draw the fuel from the bucket. If you crank the engine and it draws the fuel up, its not the fuel system. Check codes. the TRS or the SRS sensor may be bad. If one is bad, the other will follow shortly, replace them both if that is the case. IThe other thing to check is the ECM fuses. If one is blown, replace the fuse, it might start. Checking the codes will diagnose that too, because the prolink wont handshake with the ECM. If you need further help, email me.

Answer 3

When was the last time you changed fuel filters? I agree it could be electrical.

Answer 4

sounds like it has bad electrical connection SOMEWHERE, try cleaning the battery connections
