This is totally weird. She ran beautifully, cranked 1st lick like every time, last Thursday night on the way home from work. Pulled in the driveway and shut her down. she hasn't cranked since. she turns over and cylinders fire...but she won't kick over and run. I've replaced the fuel filter, plugs, wires,and the coil,distributor cap and button...her compression is excellent and she has 251K+miles. I checked fuses and can't figure it out. I've seen in other threads that the EGR could be a problem...I don't know...I'm not like congress...I don't have an endless supply of money to throw at a problem.

Any Ideas?
Thanks in Advance,

check for spark, fuel, and air

pull the distributor cap and see if the rotor spins when the engine cranks, if not it's a bad timing belt. I doubt that's it, since you said it was running fine when last parked, but it only takes 2 min, a phillips screwdriver and an assistant. and its better than wasting time and money replacing other stuff only to find out you should have just checked it to begin with.

mine had the same symptoms last year and it turned out to be the fuel pressure regulator.

any cel?
if somehow the egr valve is not seated all the way down or vacuum is being applied to the valve at start-up then it is very possible that is your problem. with engine warm and idling there should be no vacuum to the egr valve. if there is plug the vacuum hose. then try to start. if it starts and runs then you have an egr solenoid issue.
also on cb7s there is the infamous "black box" with a few sensors/ controllers inside it. which are. map sensor, purge cut-off solenoid, egr control solenoid, and the constant vacuum control valve.


but like said before. check basic specs first i.e. fuel pressure, spark, air
