the check engine light you are getting sounds like and electrical problem, have the battery and the alternator tested, and have autozone or the like pull the codes off for you and see if you can figure out what they are....

The above descriptions of the connector are very good. I washed the engine compartment yesterday, and immediately started getting the reduced enginer power code on the CIC, not performance. After reading several posts, I checked the connector on my 2003 2500HD, and found that the connector was not seated well and had gotten water in it. I cleared the water and the reconnected. The cables running from the fuse box to the connector are so short, the connector is in a bind and is pulled off-center. That is why the connector wasn't seated properly. The code went away, and the performance returned. By the way, be sure to do this after pulling the negative cable on your battery.

SOURCE: no power in part of fuse box
There is a master fuse link near the battery Maxi fuses. one of them can be blown or someone took one out to fix something else. They don't blown unless the van has been in an accident the smallerfuses blow instead. You didn't state the year as oldest ones still had the old fuse wires on the battery cable where it hooks to the starter. Older vans have 3 back in the days of carboraters. Headlights all the rest and airconditioner heater. After the fuses mains are known good the ingtion switch can be bad. Dropping the collum to get access to the wires on the ingtion switch the test light will show three wires hot with the key on or a fuseable link is bad and with the key on they'll all be hot except the start wire that comes hot in start and the heater wires will go cold. all hot with the key in run or the switch is bad jumping power to a (dead fuse) may find a dead short then each dead fuse need removed add power and plug one at a time in to find the bad boy and run him out of the school with follow the wire till the pince or added haphazard repairman's wrong guess is removed. It's hard work but someone has to do it. Good luk

Testimonial: "yes it was i checked the ignition switch and found that when i tapped on the side of it the power came on to my fuse bank that powered my pump "
I had the same problem, and the solution was cleaning the throttle body, it does need to be completely removed to be cleaned thoroughly. I just used some brake cleaner on a rag to clean off all the carbon deposits. A friend of mine who is a dealer tech had only seen this trouble code once, and this was the solution. So far, my light has not come back on and the truck is running alot better at idle.
