89 s-10 2.5 distributor ?
 

I am trying to get a truck running for a friend of mine. 89 S-10 2.5. The distributor was removed. I stabbed it with #1 cyl at TDC, rotor pointing at #1 terminal. The injector will not spray fuel . If you wiggle the black/red wire into the distributor it will pulse the injector. I suspect its bad wiring/sensor inside the distributor...I will try another distributor. Also, compression is 145-150 on all cylinders... My question is : can the distributor can be installed using any terminal as #1 or is there a certain orientation of the distributor ? I really don't want to pull the timing cover to check for timing marks just yet :lol:

As long as the #1 piston is at TDC on the compression stroke, you can make whatever terminal the rotor is pointing at when you drop it in number 1.

Zane M,
I thought so.. I guess I need to do some more work :waah:
Thanks !

Pull the valve cover and set timing with both valves closed on #1. Super easy on this motor.

Warrens69GMC,
I will as soon as I go back over there on Friday ...its a 45 minute drive :waah:
I do have another question.. I removed the distributor..It seems there is no slot for the distributor to line up and drive the oil pump ...Is this not like the old SBC ? Or is something broken ? Thanks

Yes, it should have a flat on the bottom to drive the oil pump.
