Bad Distributor
Yes it could.
It could be the ICM or the pickup module.
The spark plug gap on a 1994 Mazda 1.8L MFI DOHC is .044 (thousandths of an inch)
.032
.044 inch
I set them at between 32-35mm
have u checked spark plug wires, ignition coils, timing,spark plugs or had it hooked to a reader?
I found the correct gap setting for the 1994 Mazda B4000 to be .054. As found at the auto parts store and Advanced Auto.
It could be a stuffed catalytic converter.
You can try spraying some carburetor cleaner into the intake by way of a vacuum line or pcv hose Just a little dab will do you. If the engine tries to start it would indicate that you have a fuel problem.
A variety of things could cause a no spark condition. The distributor, the coil, the computer, etc. If you can get someone with a code reader out to read the computer codes that would narrow down your search.
It could be the spark plug wires that's what was wrong with mine.
