Check inside the distributor cap to see if the plate that holds the pickup coil has come loose from its rivets. That will let the timing jump all over the place.

By all means check all basics (fuel pres, spark, cap/rotor etc) but also check that the timing belt did not jump . I had an 85 turbo datona that did just that. I drove thru some snow and it got under the cover and all of a sudden it ran like a slug. It jumped 1 tooth. If it is off more than that it will not run.It's an easy check bring the crank to TDC #1 and pull the top cover and see where the cam is. The dist also runs off its own shaft that could be out of time. It happened in the morrning pulling out of the driveway going to work I went over some snow at the end of the driveway.

You need to check the MAP with the engine turning over. An open line will show atmospheric pressure while the engine is off and while the engine is trying to run.
You cna check the cam timing without removing the valve cover. You simply line up the holes in the timing gear with the parting line of the cam bearing caps.

two things that you might try: unplug the map sensor-the ecm will default to baro then see if it will start, if it does you need a new map; the other will require either a second person to turn the motor over with the key or you could use a remote start button, with the motor turning over tap the distributor cap with the handle of a screwdriver if the motor tries to start or stumbles more than it has replace the hall effect pickup.

Why do they have marks to line the distributor shaft with the crank on the timing belt sprokets? As long as the timing is set correctly this shouldn't matter if the marks arn't lined up, right? Thanks for all the info and advice..
Probably just so all the distributors are setup at about the same spot. Probably made it easier on the assembely line and this way the guy doing repairs can have them all rotated at about the same position.
