The timing on my 2001 ZR2 is way out of whack. The oil pump and distributor didn't line up. As a quick fix (and the dumbest thing I've done in a while) I just aligned the distributor with the oil pump since it was close enough to the timing mark. After that the blazer won't start. I tried turning the oil pump back with a screw driver but could never get it. Now the timing is way advanced. I've made a tool to turn the oil pump out of a junk yard distributor that I ground the gears off of and I've just been turning it back one cylinder at a time until I get it to run. Is this a worth while way too do it until I can actually do the top dead center method? I just have to get it running so I can have a shop fix the water pump that they messed up and then plan on doing the timing.

 

It doesn't take that long to set it at TDC do it right now or regret it later is my opinion.

 

Yeah that's why I posted this. I was curious if I should just TDC it.
UPDATE: Moved the distributor back one cylinder and it started right up. Probably will still TDC it later this week though.
