Default Engine Run time

Alright guys, what controls the engine run time light. Mine is out with KOEO. Everything works just fine until I take out my keys. The sytem just shuts off. I have green light in auto and burnen veg just fine. However, when I go to shut off the truck and take out my keys the truck just shuts off and no purge or engine run time after. What should I check? All fuses were checked and none are blown.

Do you have the dual board, or the single board?

Have you checked the engine run wire connection?

Yes, connection looks good. Alright here is the question regarding the engine run wire. Should the engine run wire be tapped into the PCM Diode (fuse number 37 under the hood) or should it be tapped into the PCM Power Relay (fuse number 30). I have actually tapped into both and neither are working and no, not at the same time. I tried one and engine run doesnt work, I then tried the other and the engine run still does not work.

Yes, follow the single white wire that goes from your manifold to under the dash and verify t has 12v to it when the truck is running. Trace it to the yellow wire on the board and check voltage there as well. Theres a diode on that yellow wire that fried on mine and caused the exact same issue and basically it wasn't letting power through the diode to the engine run wire under the dash.

What casues that? and How did you fix the issue Clay. I am at work, I will test for 12V when I get home.

Also, on my my question regarding which PCM wire to tap into. And the directions state white with blue stripe. Well, there are 2 wires that are white with blue strip fuse number 37 which is PCM Diode and fuse 30 which is PCM Power Relay. Which one is the correct one to tap into for the engine run wire?

Don't know why it failed but you can replace the diode for less than 2 bucks.
you should have voltage on both sides of the diode when you key off.

Ok I will check to see if I have power on both sides of the wire. Clay are you familiar with the following? if not does anyone else know the answer to this
