Check engine light on
Just a few minutes ago I started my truck for the first time in a couple of days. I know shame on me. No more than backing out of the drive and putting it into drive did the check engine light come on. Now, I don't know if the light came on while backing out or if it just stayed on from the original start of the truck. I was busy waving at the kids in the window.
Couple of questions now:
1. I have the DP. I always forget to set it back to stock before starting. Do's this matter?
2. I had to remove the radio 2 days ago so I can send it to Kenwood for repairs. Wouldn't think it can be part of it. Radio still out while driving.
3. About three weeks ago I refilled the AC. Dont know if I added to much or what, but I drove about 800 miles just after filling it.
4. Isn't there a few readers out there that would tell me the problem? Which are inexpensive and or easy to operate?
Thanks in adavnce,
Al

If the check engine light is on, you have a code stored. Not all code readers will read out trucks. Get it read and let us know what the code is. None of what you did would throw a code.
EDIT: I leave my DP in 80e most of the time and never change it to stock before starting the truck.

Auto Engenuity is a great scanner for these trucks, but it's not exactly cheap, and you'll need a laptop to make it work.

A little further information if it helps. I dont think it will, but I had a little more time before I had to go to work.
1. I turn the key.
2. all the lights are on.
3. wait to start goes off and ready.
4. I hear the noise it always makes right before I start it. Almost like a woosh sound.
5. and the check engine light comes on before I start it up.
I am going to see if my dealer friend can hook me up in the morning.

The check engine always comes on when the engine is not running. It's normal.
Also keep in mind that generally the check engine light comes on when something has been detected that can effect the engine's emissions.
The best thing you can do now is learn more about your engine and pull the codes and see what it's trying to tell you.
If someone from FTE is in your area they may be able to give you a hand if you don't have a scan tool or you may need to take it in and have the codes pulled.
Let us know what you come up with.

I went to the dealership this morning. Luckily to me my stepfather is a ford retiree and now is a dealer trader driver for fun. Anyways, he made a call for me and it was setup that I get it done for nothing. As Jesse James says on monster garage "freebie". I still offered him $25 dollars. I was told it costs $85 to hook it up.
Ok he told me the code is a mystery one to him not telling what it was. He did tell me the scanner thing said it was code P0677. He said he would research it for me also, when he got the time and the boss wasn't around.
Anyone know what this is P0677?
Thanks in advance.

good grief! a Mystery code, this is just a stupid scare tactic to try and get him to let them fix it and rape his wallet!!!
Agreed on the P0677 / Cylinder 7 Glow Plug Circuit Failure.
Son, I recommend investing in a Auto Enginuity tool or a digital guage that will pull the codes for you and don't let the dealer try and rape you but nice job on the freebie!
So, now that we know what the error is does anyone know of a write up on how to service our little GP friends?

It could be as simple as wire chafed on the harness going into the valve cover, or the GP wire connection sliped off the GP. I would start by looking at the wires, looking for one that is grounding.

I will start looking as soon as possible. I know I have a couple extra days of coming in the next week or two.
Am I damaging anything by still driving it? The guy cleared the reading but just after three starts it came back on.

You won't hurt a thing by waiting a month or two before changing the glow plug unless you have a vehicle inspection coming up that the light will prevent you from passing.
