Question about 1999 GMC Yukon
I'm lost! code was setting prior to new engine however, engine 5.7 LTRE replaced as well as, fuel rail and injectors, distributer, cap and rotor, o.e.m plugs and wires, coil, fuel pump and fuel filter, crank sensor. all ignition new except ignition control module. it is misfire under hard acceleration, towing and climbing and cruise at 1800 rpms or higher on cylinders 2 & 3. most of these items were replaced with the intent to make a used "NICE" vehicle new again now I'm perplexed and am giving up. 2&3 cylinders are the same pin on the crank sensor..........HELP! thanks
I can recommend you to RUN the scanner/computer for easy diagnostic and fix it. The electronic vehicle is complicated you have faulty the PCM or BCM.etc.
see the diagram attached.
God bless you

the starter could be too close to the flywheel. try adding a couple of starter shims. it also could be drawing to many amps from internal corrosion from water intrusion.

no codes. most direct components changed.
computer. take it out or have the truck towed to the shop/dealer to test the computer.

Code 1351 is for the ignition control module.Ignition control circuit high.This module is on the same bracket as the coil.Before you buy a new one.Try a salvage yard and get a used one.
