Got a N-14 that I put in a 2005 Volvo 670 back in 2015, ran great until one day it started missing and lost power went a few miles and it cleared up fastward month later lt did the same thing,I have put ln new injecters,injecter harness,Ecm,fuel pump,Accelerator pedal sensor,turbo boost sensor,engine position sensor and it still has no power in fact if I unplug the turbo boost sensor, the power is better at throttle but fuel is not there any ideas
I know this is going to sound lame but did you check/test batteries, charging system etc? We get alot of intermittent faults because of this.
Yes, checked all the grounds from the block to the frame, the grounds for the starter, alternator checks fine,new starter, fresh batteries checked all the positive cables and all the fuse plus theECM ground
Ecm connector pins? All tight and in good condition? What style of comnector do they use from the truck to the engine harnessing? I know we had huge issues with the emgine harness 90pin OEM connector harness.
