Message	I was driving my 90 300zx tt accelerating from a stop, It died as I was going into 1st gear so I started it again, and it died after about 2 seconds, I pulled over and tried to start it again, it starts but only for 5 seconds and died. Things that I have checked or tried: 1. starting fluid 2. spark (very seldom) 3. cleaned ignitor connection on front of engine and replaced it 4. checked computer to see if it would give me a code got (55) no problems 5. When I crank it over, it does not backfire or anything 6. cranks fine 7. hooked up extra coil I had with a spark plug outside engine and sparks once in a while (very very seldom) 8. I replaced the CAS 9. Still no spark I have tested 3 plugs 10. I have replaced the PTU as well Could still be CPU but i am saving that as a last resort, does anyone know how to check and see if a CPU is bad? I took the Power transistor relay out an checked the code just to see if the CPU would give me one and It gave me the correct code 21, could the CPU still be bad even though it gave me the correct code? What could this be? Please help!
