Wasnt my idea. Boss man wanted it changed. We have 4 of these trucks and have never had a problem changing IP's. Its always been take the bad one out, put the new one in and it runs. For some reason this one wants to be a pain
Have a 99 gmc 2500 with the 6.5l td. Installed a new injector pump, lift pump, fuel filter, injectors and pmd box and now it idles rough. Reinstalled the old IP and it idles and runs fine. Installed a different new IP and it idles rough. Any help?
