I had the injectors out of the engine. I put them back and buttoned everything up and now it won't start. I cranked it in 10 second bursts about 20 times and not a sign of catching. There's no fuel at the delivery valves or the injectors. There's a little fuel when I crack the line from the pump to the big filter. There's no fuel when I crack the line from the big filter to the IP. The big filter is pretty full but not overflowing. There's an air bubble in the small filter. I don't know if it was there when the car was running.

I noticed that part way though cranking, the stop lever was all the way down and tended to go down on its own. I tied it in the up position and cranked a few times and now it stays up (sounds like a men's product endorsement). Does this mean anything?

Any help is appreciated.

Thanks,
Sixto
