Asked by willie baileyAnswer
Check crank sensor.
pour gas in the intake.does it start?
The plugs are wet, it's getting gas. The spark is present at the plugs, just weak. I can not find a crank sensor in my Mazda book or on lie. Where is it located?

My car is a 1983. It does not have a crank sensor, it has a distributor. The wiring diagram is not for a 1983.
did you do what i asked?????????????????????
I poured gas in the carburetor, did not crank, all four plugs are wet. I checked for fire from both coils. the leading coil is producing a stron spark, the trailing one nothing. the car turns over fine, does not attempt to light off. Will it attempt to light off with only one coil? I was going to swap the igniters, attached to the distributor, with the ones on my 85, the 85 has aftermarket igniters. Help?
pull a fuel sample and see if its good gas.no smell or 2 different fluids in the jar.if ok then replace the fauly bad coil.
The fuel is new. I swapped the coils, didn't fix the problem. I swapped the ignition igniter, they are mounted on the distributor housing with two smal screws. The no fire condition went from the leading coil to the trailing one. A new igniter cost more than $200.00 dollars. Do you think this is the problem. Once again I have changed the coils, plug wires, distributor cap and rotor, spark plugs and all four plugs are wet with fuel. What do you think?
