Toyota TownAce 7K — Cranks but Won’t Start After ICM Replacement was created by morongwamoseki5
Hi guys, I need some help with a Toyota TownAce with the 7K engine.The customer says the truck was running fine, then suddenly developed a crank-no-start condition. It was previously diagnosed as an ignition control module (ICM) problem, and the ICM was replaced with a new one.After the replacement, the vehicle started and ran normally for a week or so, but the exact same problem has now returned.The work was done by another mechanic, so I’d like to approach this systematically rather than assuming the ICM has failed again and avoid to  "be a part changer

I don't know what is a Toyota TownAce or a 7k engine, but what have you checked so far?
Generally speaking:
Does it have spark?
Does the ignition control module have its powers and grounds?
Is it receiving inputs?
Is it providing outputs?
