We just took it on a 100 mile trip and it was fine. Parked it a few days and took it for a local ride and it started missing then quit altogether and wont start. Cranks OK, but does not seem to get spark. We ran a spark test which indicated the crank sensor (in distributor) was the culprit, replaced it, made no diff, new coil, no diff. (there is power getting to the coil) I tested the coil wire and I think it was 8 ohms, which I think is OK don't remember. Before we determined it was spark I did replace the fuel filter just because the car had been sitting a long time prior to the 100 mile drive. The fuel filter was full of what looked like mud so I'm glad I did that anyway cuz it needed it. We do hear the fuel pump kick on and you can smell gas a little bit after cranking a few times.

Any ideas? Thanks.
 
How much fuel pressure? The pump can still make pressure even if it was bad. Would be very low though. I think my buddies car ran with the pump putting out about 20psi. Barely ran but would still idle IIRC.
 
Well, we got it figured out. Simple issue, thank goodness. When I replaced the Crank position sensor in the distributor, I did it by just getting a whole rebuilt distributor from o'reillys for $60. Seemed easier than swapping gear and all. Still had to swap over the new TFI, rotor and cap, etc. Anyway, I got everything in exactly the same position, however, the new distributor was clocked one whole firing position off. As it turns out, the fix was just to move all the plug wires one position counterclockwise. Car runs like a bat outta hell now.

Thanks to everyone for their input.

good to hear.
 
new dizzy have a machined gear or a cast ? .,. one is for a roller motor the other is not ,., they tried selling me a dizzy with a cast gear and tried to argue with me when I told them they were wrong , same with the TFI , make sure you got the right one , the black and grey ones are pinned differently , the grey one will work but throws a code .............. I went threw all this when I had my 95 gt , just trying to save you a headache lol
