Previously changed the OPS several months ago. No to changing the oil pressure sending unit. everything seems to be working just no acceleration. Idle is fine. Drives fine.
Hello. New to the forum. I have a 94 K3500 6.5TD. Just had the fuel control module changed along with the lift pump. Now I have no acceleration. 70 MPH top speed. Any kind of load will slow considerably. Turbo seems to be working fine. Waste gate operates normally. Any help would be appreciated.
