B2844 Ignition Malfunction
Problem. Truck will start but will not allow the shifter to move from park for 30sec-1min. After that all is well.
Also The other items tied into this are the directionals, power mirrors, locks, information center, and radio. If the truck sits for that 30 secs, I can drive with all power, then within another 30 secs the power for these items shuts off. Driving down the road it seems like it loses power to these items under 1200rpm, then kicks back on if at 1500rpm and above.. Voltage is fine when idling, and It seems to come and go at random.. Then there are other times throughout the day where Everything functions normally for a bit.
I'm not sure if these are related, but I'm leaning towards shift interlock problem of some sort?
