Good day everyone,
I found this article helpful when replacing my lb7 injectors, I am in reassembly mode now but I have hit a snag;
On the driverside, in a wire grouping with the baro sensor there is a 3/16 eyelet on what looks to be #8 stranded wire dose anyone know where that connects?
thanks in advance

Ok here it is. I was getting fuel in the oil. Due to the economy too many kids whatever the budget was not enough for new injectors so I pulled the injectors. The front 2 on the drivers side had blown o rings. Got new o rings and seals. Cleaned injectors put a little silicone one threads reinstalled. Rebuilt fuel filter housing. Checked all fuses and wires. Primed over and over and cranked and cranked. It will try with gas on a rag but won't go on its own. I have built cummins cat and detoit motors for heavy equipment. But they were old school. This is driving me nuts.I have tried every trick I know but still nothing.

 

You'll need to replace the injectors man. Those O-rings are only there to keep dirt from getting under the valve covers, not to seal the high pressure fuel lines to the injectors.

Your injector bodies are more than likely cracked, and the only solution is to replace them.

If you are on a tight budget and you want to replace only the 1-2 injectors that may be leaking you'll need to remove both valve covers, reconnetc the high pressure fuel lines and wiring, then start the engine without the valve covers, and visually inspect to see which injector(s) are leaking.

While you're at it, disconnect the fuel pressure regulator, that way the fuel rail builds up maximum pressure, so you don't miss a leak.

Wishing you the best! - Titus
