The relation between the dash error messages is the Electronic Brake Control Module. There are probably codes stored in the computer. Check it out, if there are any they will help you localize your problem. Also I would guess that these are dues to a loose connector or cut wire or something like that due to the install, good idea to recheck the whole underdash area since there are steering/brake sensors located there wich the EBCM uses.

I have the Viper 5900 installed and whenever I use both factory and Viper alrams, the factory alarm locks out the fuel pump. If your H3 cranks, after cranking check around the truck if you smell gas, if you dont smell any gas after a decent crank then your fuel pump is being locked out by factory alarm.

The only function of the hood pin is to prevent the remote start from starting when the hood is open. Safety feature.

good idea to check:
>>Fuse 29-EBCM
>>Fuse 52-EBCM+Sensors
>>Fuse 58-TCCM switch
>>Fuse 64-EBCM
>>Fuse 67-EBCM
>>Relay 66-Fuel Pump/Pump Fuse (if you dont smell gas)
>>Relay 87-ABS as well as otehr stuff

wont hurt to have a look at those make sure they work.

Edit: also if installer removed/disassembled teh fusebox to route or tap into fuses, recheck if the top portion of the fusebox reseated properly into the two connectors underneath.
