Well I finally got to topping off my fluids and cranking her over today.

I pulled the powertrain 3 years ago and half way through my project had to stop and store it for awhile.

This summer I put it all back together and just dropped the engine and trans back in 2 weeks ago.

So today I cranked and cranked and cranked and... nothing, not even a sputter. Honestly I was just happy that no valves hit pistons.

After a bit of cranking I saw that fuel was back in the lines and I cracked the #1 injector to see that indeed there was fuel.

In my excitment to get her going I forgot to put fresh fuel in the filter so I'm thinking 3 year old fuel could be the problem.

I also did not have the tool for setting the timing on the IP so I did it visually. It took several attempts but I'm fairly confident that I lined it up right.

So I'm wondering a few of things;
1. Do I need to crack the injector lines while someone is cranking in order to bleed air out?
2. Would that old fuel alone make it impossible to start?
3. How close to perfect does the IP timing need to be in order for the car to simply run?
4. What are some other likely sources I should be investigating?

Glow plugs are new and seem to be operating, they all worked just fine when I took the engine out. The engine did not have any trouble starting prior to disassembly.

Thanks!
