Sounds like your injector timing is too advanced. Re-stab the
distributor. Pull the #1 spark plug. Get a socket/ratchet and turn the
engine by hand until the piston on the #1 cylinder is coming up on the
compression stroke (make sure it's not on the exhaust stroke!). When it
starts to come up, place your thumb over the plug hole. Make sure you only
turn the engine over with the wrench, not the starter, I don't want to be
blamed when you come up missing a finger :)
When you stop feeling pressure escaping stop. Make sure your turning the
engine in it's normal rotation direction. Check the distributor rotor in
relation to the #1 terminal on the cap. Watch the rotor so you know which
direction it travels when the engine is running. The leading edge of the
rotor should be right at the cap terminal for #1 plug. If not, and it's
off a pretty good amount, pull the distributor and move the gear one tooth
(backwards, opposite of normal engine rotation), then insert it back in.You
may have to turn the engine slightly to get the oil pump shaft to go in the
bottom of the dist. Button it up and fire it. See how it runs. Since the
distributor controls injector timing, using a timing light won't be any good.
