Re: ic pump relay
Yep:
And double yep:
"Intercooloer pump fuse location behind alternator. Fuse is in a weather pack connector and the top has to be opened to expose the fuse."
The fuel pump, AC and IC pump relay are interchangeable so you can swap them to see if that's your problem or not. More than likely, the fuse will be blown due to a dead pump as mentioned by dgoodhue. There are several vendors on here who can set you up with a new IC pump if that be the case. Also, if you still have the stock chip, the IC pump will not turn on until the temperature has reached 215 degrees... Most folks hotwire it to be on when the truck is running for this reason. You can get the pump to turn on manually by putting the truck in ALDL mode . All you have to do is put a paper clip between the "A" and "B" terminals with the ignition "ON" without the truck running. This will also allow you to see what trouble codes are stored in the ECM as well. HTH's

Re: ic pump relay
Best scenario is the pump "gets told" to turn on by the key (tie the yellow wire TTV8 mntioned to ground). Regardless of engine temp, you ALWAYS want intake air temp to be as low as possible.

Re: ic pump relay
No one shows having an I/C relay in their computers. This is great info from the past. My relay went out and the pump went out the at same time.I put a lightning pump on it last weekend and had to put a switch in place of the relay temporarily.
