My issue was both the vehicle did not crank on some occasions and it cranked but it did not started. But to confirm I went out to the vehicle and installed my old K40 and the vehicle cranked but it didn't start. You maybe right you may have some other issue, unless the K 40 has two of the relays one for the ignition and the other for the starter, but I'm not sure if this is the case. Perhaps someone can let us know the systems that each of the relays in the K40 controls?
