1995 GST, was running fine before blowing a timing belt. New head and belt has now been installed but it won't start - no fire to plugs. Engine cranks over but there is no spark.. Crank and Cam sensors are plugged in, as is everything else I can think to check. Any ideas on where to start to determine the problem?
I'm new here, but I've been around the block a few times.. Thanks

 

check the distributor-power transistors-igintion coil-spark plugs- plug wires

 

It was the crankshaft sensor. The backside of it was completely broken off. It must've taken a hit from the belts when they shredded.

 

sigh, it's always a sensor or something like that[:-] Kinda miss the old days where you could start a car with no battery by pushing it down a hill and popping the clutch.

 

There's more to the story now.. After replacing the bad Crankshaft Sensor, it would start, but only run on 2 cylinders. Tested the Camshaft sensor, and it was broken too!. Replaced the camshaft sensor, and that should be it right? No. Started it again and it hit on all four but ran terribly rough at low rpm and would not idle. It was a intake manifold vacuum leak - parts store gave me the wrong intake manifold gasket. Fixed that and now everything seems to be ok.

 

LOL, oh man, never simple is it? Glad you got it figured out though.
