i have a 91 f-250 7.3. a buddy thought he knew how to turn it up by messing with timing. and idk how to get it back to normal.. can anyone help me? thanks

What exactly did he do?

the housing where the injector pump mount. he lifted that up and turned the gear inside there. idk i know now how to really turn the pump i just need to get everything back to normal... thanks

little off topic but what did that do to it? got a guy curious

Thats bad, thats very bad. You are not supposed to remove that cover. The timing is adjusted by loosening the IP and rotating it, not the gear. You dont usually want to adjust it more than a dimes width either. Does your truck still run at all?

made it not run at all. then i put the motor on top dead and put that gear back the way it was supposed to be. even after that it will run but takes forever to start and run like ass when it finally starts..... should i loosin the pump and move it a lil and see if that works???

on the timing tab on my trick there are two holes.. which one is tdc

From what I understand, there are two dots you need to align, one on the IP gear and one on the cam gear. If you get the motor to TDC you should be able to see the cam gear dot with a dental mirror so you can line them up(This is with the top cover removed). These motors shouldn't be timed by ear, you will need to take it to a shop with the proper timing meter once you get it aligned.

ok thanks, i appriciate it guys
