Hello fellow mudders. I own an imported 1990 Toyota Land Cruiser equipped with the HDJ81 4.2L inline 6 diesel engine. About a month ago the truck wouldn't start, after pumping the fuel primer on the fuel filter to build pressure then the truck fired right up. After a few seconds later I noticed fuel was leaking from the diesel injection pump. Pulled the injection pump off to get it rebuilt and reinstalled it.
After reinstalling everything, I have the fuel lines disconnected from the injectors and while cranking many times, I am not getting fuel out of the lines. I even have the fuel return hose capped off in hopes to help build the fuel pressure but still no fuel out of the lines. Tried looking up fuel bleed procedures for this particularly engine and didn't see anyone post anything.
The shop that rebuilt the pump mentioned that the pump was not outputting fuel pressure to specs after the rebuild. They asked if I had issues with starting which I never did so I decided to take the pump as is and give it a try. They said that if it didn't work then I would need to bring it back for a distributor replacement. I feel that even if it didn't build enough fuel pressure to specs that it should at least build some pressure to drip out of the fuel line at the injector but it doesn't.
Any suggestions or recommendations on what to check or how to prime the fuel system would be greatly appreciated. I want to rule anything out that I might have missed before pulling the injection pump back off to get the distributor replaced on it. Thanks in advance.
