My brother bought a chip (+60 HP) for his truck yesterday. The truck is an F350 diesal crew cab. 7.3 engine. The story goes like this: After he got the chip we drove his truck back to his place. Removed the fuse panel cover inside and opened the hood. Under the hood we took off the three bolts holding the exterior fuse box so we could adjust it and get to the bolt holding the computer in. Took the two bolts off the shell of the computer box holder then went outside again to get the last bolt out. Ratcheted the outside bolt (that holds the connections together) off and disconnected the computer. Once we got the computer out then we took off the old chip cover and proceeded to remove the cosmoline from where the chip attaches to the computer. We just used the rough side of a Scotch Brite to slowly wear it off. We then disconnected the batteries (probably should have done that earlier) Once that was done we attached the chip and put the cover back on. Pushed the computer back in and reconnected it outside. Once we got it reattached we put the exterior fuse box back in and reconnected the batteries. Went to try the truck and when we turned the ignition the "Wait to Start" light wouldn't turn off. Truck wouldn't start at all. So after that we took everything apart again. Battery->Fuse box bolts->Computer->removed chip->reattached chip cover->reattached computer->reattached batteries. Now when we try to start it there's no power to certain things. When we turn the ignition a couple of the dash lights still come on but nothing happens when we try to start it. Power locks and power seats still work but the starter, headlights, well all of the lights, etc don't anymore. Everything is hooked up like it originally was but now we don't know what to do. Brother thinks it's probably a relay we popped or something. Any help is appreciated. |
you used a scotch brite pad on the computer board???? Go buy a new computer. |

What do the instructions say about the battery, keys, other precautions? Or did he get it off eBay or other source, used, with no paperwork? There are a couple Ford techs on the site, but you may not like what they have to say about this kind of DIY work, and I can't say it isn't often justified. That 's the price you may pay for their advice. |
