Truck wont start after attempt at chip install

Hi-

Purchased the 6 position bully dog chip for my 2001 Ford F250 7.3 L. Followed the directions - pulled the computer - scuffed off coating on contacts - re-installed and truck wont start. The "Wait to Start" light also failed to come on. Its rolling over just seems like it wasnt getting fuel.

Pulled switch - re-scuffed and cleaned the contact again - re-installed - truck still wont start.

Got frustrated and decided to call it quits - pulled the chip an put everything back together - TRUCK STILL WONT START?!?!? Now the "Wait To Start" light does come on.

To me (the untrained ear) it sounds like its not getting fuel but I didnt get a book with my truck so I have no idea what fuses to check.\

Any help is appreciated as I need to get my truck back on the road ASAP. Thanks!

pull out your PCM and make sure the contacts are bare metal! and then, omce your sure they are clean, scuff them a little more! you can hurt them, all you can do is brake them off, buty thats hard to do with just the scuff pad

When you say PCM - what is that the computer cartridge?

I guess my problem is that Ive pulled the chip and my truck is still buggered up. I thought everything was supposed to return to stock with the chip pulled?

thanks for the reply!

Did you have the keys out of the ignition when you pulled the pcm out?

I do not believe so but Im only about 75% sure of that. What does that mean - with the keys in the ignition?

No idea if its throwing codes - I have way of knowing if it is. It will turn over - just will not start. And no - no scan tool.

I appreciate the help.

If the keys were in the ignition, the PCM could have had power. Which means you possibly fried your pcm....

So if the PCM had power and I pulled it- -it would cook it? While I am no mechanic I cant imagine that cooking a printed circuit board can occur simply by disconnecting it. There were no indicators that anything had arc'd.

Also - if the computer was cooked - Would the engine even turn over?

Do you have a WTS (Wait To Start) light when you roll the key on?
