Hey guys my 02 died yesterday and won't start my programmer won't connect I tried to use it to get codes but no luck the only thing out of the ordinary I can see as of now is that when I turn the key on the wait to start light never goes off or the check engine light even when cranking anyone have any ideas

need a real scanner. pull the programmer off.

 

[texaspipeliner]

Yea I was just gonna check since I had it handy and I was gonna de tune the truck but it won't link up to it so I can't remove it or anything I'm baffled

 

[texaspipeliner]

Also I just found out number 22 fuse is blown and apparently the circuit is shorted out somewhere because a new fuse blows as soon as the key is turned on

Unplug the fuel heater and replace that fuse. It should start up.

Fuel heater most likely has shorted out.

With fuse 22 blown, no programmer or scanner will connect to the PCM.

^ precisely.
What programmer you got?

I have an edge evolution but I'm pretty sure its useless now lol but I'm not putting it back on my truck when I get it running again it can stay stock until I buy a ts6

 

[texaspipeliner]

Also I tried unplugging the fuel heater nothing changed

 

[79jasper]

Did you change the fuse after unplugging the fuel heater?

[texaspipeliner]

Yes and nothing changed I got a bad feeling I got a burned up pcm or idm

 

[79jasper]

I would say pcm before idm.
Pcm controls the glowplugs and the check engine light.
The edge may not be able to pull the real codes.
Also check the relays. I believe there's one for the PCM.

Refer to the owner's manual, and disconnect EVERYTHING associated with fuse #22. Then install a new fuse, and turn the key to RUN. If it doesn't blow, turn the key off and start reconnecting things, one at a time, and turn the key on at each step, until it blows. That will tell you what has shorted out. IIRC, your truck has both a glow plug relay and a similar high-capacity relay for the intake air heater. On the earlier models, the GP relay was also energized by this same circuit. Same may apply, along with the IAH relay, to your truck. So I'd start by disconnecting those relays.
