Need to go to work!!

[Joel]

I took out my DP chip yesterday. Keys were nowhere near the truck. All seemed to go well, but in my over confidence, I didn't check to see if it started after that. Now I need to go to work.....
-It turns over but wont start.
-The glow plugs do their thing.
-When I crank it the tach and speedo both go from zero to maxed out. I dont know if this is normal or not.

My best guesses to how I screwed up are not putting it back to stock before taking it out, do you have to do that?

I didn't disconnect the batteries, do i have to do that?

Anything I can try or do I need a new PCM? HELP!

how cold is it there... may be havin issues with cold start...

[Joel]

its not cold at all. And Ive never had any trouble starting this truck. I'm really leaning to PCM. I just wish I new exactly why befor i go drop cash on it

did you double check the connection to the PCM??? is it on all the way??

[Joel]

yeah ive done it a couple times now. all the pins are good. however, the last time i went to take it out, as i disconeccted it the dash beeped at me. So I think I must have needed to disconnect the batteries
But DPs instructions dont say to do that. Is it supposed to be common sence?
Do you know if they can test my PCM with it out if the truck?
Thanks

no they cant.... only way i can think is to have it in the truck and have someone run a scan on it with a GOOD scan tool (AE or snap on)

[Joel]

rough. any advice for me? Dp is out of the office today. And I HAVE to get it running today. at any cost.

Take a look at this thread, this is what happened to me when I messed with my PCM plug under the hood and, inadvertently, disturbed the fuseable links connector...

POTENTIAL ELECTRICAL CORROSION if your truck is like mine......

you said you are getting a wait to start light???

what year truck is it???
