Since i have rebiult my engine and got it running on sunday. I got one thing that bothers me about it. Crankings times are always varying before start-up. One time it'll start as quick as my old 12v other times it'll crank as long as a PSD. I tried parking it on hills to level ground. outside temp and engine temp doesnt seem to do anything with it.

 

You might recheck all hose connections. Make sure the filter is purged of air. Is there a possibility the cam or crank sensor or wiring is damaged?

 

i put a new but crank and cam sensors in when i put the engine in. put 300 miles on it and it still does it.
