Diagnostic Tips

Be sure to check pin fit on all injector connectors. LML and especially L5P are common for setting random misfire or injector circuit faults from poor connections at the injector. Many times shops will blame the injector and replace both the injector and connector when it's just a connector issue. Make sure to use good quality heat shrink butt connections or solder connections with heat shrink to prevent water intrusion. Tape securely to prevent movement and abnormal wear. We have included an image of a repair done at Orangevale Diesel for reference.
