I picked up a 75 240d 4 speed "project car" for a song. Looked it over, put oil in the injection pump fixed a couple messed up things and put it on the block heater overnight. The primer pump was replaced I think, old one with the car. It doesn't work right. You can pull it up and it springs back in, don't see fuel moving in the clear return line on the last injector(not right I know). Anyway I just cranked it a bit and it started popping and puffing smoke. Took awhile but it finnally fired and ran rough while purging the air out of the lines with some throttle. I let it slow down a little too much and it stalled and I guess backfired or something. Then no popping or smoking. Checked cam and crank timing and they look spot on. Looks like new cam sproket and chain with a master link. I cracked injector 1 line and it looks like it's starting to show fuel at like just above 10° btdc. Maybe as much as 15° Specs say 24° is correct. 40 tooth sproket is 9° per tooth. I'm figuring it jumped a tooth on the pump sproket. Would that make it not run at all though? I feel like something sounds different while cranking but maybe cause no popping. It's hard as **** to turn over, tons of compression. Am I missing something?

Hard to see but the balancer is on the 0 and T Mark between 10 marks. Cam is dead on the witness mark.
