when i installed my injector pump(crank and cam were timed from company, got longblock) I pointed the cam gear mark up and the injector pump mark down, facing each other, is that right or do they both face up?

injector pump gear timing

I believe the proper way is to bolt the cam gear onto the chain driven cam gear so the dots are in the same positon ponted down. then rotate the engine until the dot points staight up and then the pump gear dot lines up with it. Hope that made sense

You sure have a better way to say that then I did.:rolleyes5:

if that is 180 out will the pump not pump to the injectors?
Firstly - the IP pumps less than a teaspoonfull of fuel to each injector - it is not like your waterhose when watering the grass - you'll see a small dribble, then nothing till the next time the cylinder is ready to fire, then a 'nuther small dribble, et cetera, ad infinitum
Secondly,the operative phrase being 'next time the cylinder is ready to fire', indicates some form of distributor addressing each cylinder in some form of timing schedule - which you got and which it does, just like an ignition distributor, butcept for fuel.
Therefore, the FSD\PMD will still drive the Fuel Solenoid, the chamber will still fill, the pumping plungers will still follow the camring, the pressure will build, and fuel will still arrive at an injector - just won't be the correct injector for the expectant cylinder........if the IP driven-gear mark is not correctly aligned with the IP drive-gear mark, on the camshaft
If the crank\cam marks are not aligned, the crank prolly won't make one full revolution - if they are aligned, but the IP gears are not aligned, the crank will spin but the engine won't start - also won't start when timed if injector pipes are not bled
If you pull the waterpump off you can see the mark on the IP gear, and by peering, you can see the mark on the camshaft gear when it is at 12 o'clock - line'em up, and yer good to go........after the injector pipes have been primed
