89 s-10 2.5 distributor ?

[sleepertruck72]

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
