90 GSX Won't start

Ok, here's the story.

Driving along on the highway. Whenever I shift gears the car cuts out, let out the clutch, it starts back up. So I get off the highway, stop at a red light, and it cuts off. Now it'll crank and try to start but it won't start, so I've gotta push it into a parkin lot and wait for a tow truck.

I get it home and I'm lookin at just about everything. I've got the Pocket Logger system and nothing really looks out of the ordinary. I can't really find a culprit. New plugs, wires, fuel filter, coil, ignition module. It's just not starting. Fuel pump is good (pocket logger gets it to turn on), I put a used (working FPR).

I just can't figure out whats keeping it from starting... ANY ideas?

Well, I got it started today.

It won't idle on it's own, I gotta keep it at 1500rpm to keep it from completly stalling out. It has a really rough time idling at 1500 tho. Sputters and doesn't accelerate at all.

Smokes a little bit but not a huge ammount. So now I gotta figure out what's makin it run so rough.

if you said i was smoking do a compression test.

Crank Angle Sensor...?

if all that is wrong try the cmap or crank pos sensor my car did the same thing until i got a cam pos sensor.

if it makes alout of clicking noises and stuff and begins to smoke more and more then its probably your engine..right before my engine completely blew up it was idleing at 300rpms and if i didnt hold the gas down it was stalling out. my best friend is a mechanic and he told me it was because one of my cylinders was shot. anyway hopefully thats not the case its an expensive fix to get a new motor. good luck

Sounds like a crank or cam pos sensor to me so far.
