you Timing belt has slipped.? if belt is KNOWN ok ,the try instant start
if it runs for 2 seconds, get all over fuel pressure.
also have you made sure the spark wires are 1,3,4,2, CCW rotation of the rotor.
ccw=counter clock wise.
symtoms.
1 spark good ,
2:fuel injecting and starterfluid all no go.
3: you will discover Ignition timing way the heck off (static)
4: you will discover compression is low
5: you might discover can shaft doesnt turn (danger of hurting valves for sure)
if compression is good. over 100 psi or so but really should be 150 or more.
and spark is timed. (static timing)
and cam isnt slipped. ( or worse setting ign timing to a wrong cam setting)
car must start with instant start ( only 3 rules)
