1994 6.5L wont stay running ECM code 13

[chrisk1500]

Your code 13 is from the ESO.

It is a serviceable item on the IP. It is a tall silver cylinder with a wire pigtail coming off of it. Dave is getting a little confused here between the fuel solenoid and the shut off solenoid.

When the engine stalls, disconnect the ESO wiring harness and make sure that there is a 12v signal coming from the engine harness to the ESO. If the signal is not present, there is a wiring issue, if the 12v is present then you need a new ESO. They are easily replaced....like a 5 minute job!

Right. My bad. I actually have a couple of 'spares'. Let me know if you need one for test purposes.

Thanks for clearing that up, Chris!
