Default Re: Another crank but no start dilemma

Actually I've replaced quite a few relays where the coils go bad (open) once the relay has been energized for a bit. Now I apply 12 volts to the relays for a minute to ensure the relays work on the bench before I return them to owners.
You can close the relay manually to see if the problem goes away.


On a side note I've yet to see any other relay, other than the Air Pump relay with bad contacts. Have also noticed more frequently that the "on all of the time", Engine, Traction control and Fuel relays are discolored. Guessing that it's from the heat of the coil.
