Voltage at ignition and leaving ignition.
Won't crank except at starter no spark on 2001 Mazda B3000
Will not spark unless engine turns over. Sounds like you say the starter will spin freely but engine will not crank. Locked up engine?
Sorry on info engine cranks voltage at ignition and leaving ignition no cranking from ignition can jump at starter still won't start
Ok. I am not a specialist at these but the original complaint sure sounded like a locked engine so I jumped in. There may be a relay effecting your problem. Someone else on here may be able to help.
