Oiwa Garage Tech Note
"These modules are heat-sensitive. A truck that stalls hot and fires again cold is the classic module story - swap it before you chase the fuel system."
Frequently Asked Questions
Does the module need programming?
No. The module is a direct replacement with nothing to reset.
How do I know the ignition module has failed?
A no-start or stall that comes on with heat and clears when cool is the classic module story. Another important clue is a truck that starts normally when cold but will not restart once the engine is warm - if it fires again only after cooling down, this is likely the culprit. Another way to check the module, which sits on the distributor, is to remove it and inspect it - sometimes it has battery corrosion that needs cleaning up.
Should I replace the coil or distributor too?
Not automatically - if spark returns with a fresh module, the coil and distributor are fine; chase those only if the misfire stays after the module swap.
