1984 911 3.2 Cranking but won't start

[1stcarpaidfor]

I'm new here, so hope this is in the appropriate place. This car has been stored, not driven since 1999. Recently put in new Battery, fuel and started right up, but smoked like crazy from all over/around the engine. Shut it down and was talking to my wife about it and she reminded me that she drove it last (10 yrs ago) and put oil in the gas tank. I drained/cleaned tank, flushed fuel line-also used fuel stabilizer, changed filter, new plugs. Now, car cranks and seems like it wants to catch for-about 3-5 seconds, but doesn't completely turn over. Any suggestions? I usually do most (about 90%) of my own vehicle work, so I feel I am able to handle this without going to technician, I hope! Thanks for your input and patience.

A few things to check. First is the DME relay under the seat. usually these are just replaced. Also, keep a new spare in the glove compartment. These have been known to just quit on their own.

since you were in the engine bay messing with fuel lines I suspect you might have created a problem with the speed and timing reference sensors. These will be located in the rear center of the engine since they read the flywheel through a notch on the transmission bell crank. The gap might have been disturbed or they might be unplugged.

Also, you might want to check the tank fuel filter screen to be clogged (are you getting fuel?) since the car sat for so long. The system needs to be primed yet, the fuel pump does not run unless the engine is cranking. You could jumper the fuel pump to prime the system.

btw, This is the turbo section. The general 911bbs would probably more help.
