SOURCE: 1998 gmc sonoma push button 4x4 busting diaphram vacuum actuator

On top of the transfer case is a vacuum switch with 3 vacuum lines connected to it. This switch controls when vacuum is applied to the vacuum actuator. This switch can fail partly and allow fluid from the transfer case to be sucked up into the vacuum lines and anything connected to them as well. When you replaced the actuator before, did you notice any oily fluid inside of it?

P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1
I would have the repair shop see if they either damaged or left disconnected the oxygen sensor for engine cylinder bank one upstream sensor, this sensor would have been disconnected if the oil pan was removed.

if you can't find one, it might be that either it doesn't have one (as some cars) or it might be located inside of fuel pump assemply (inside fuel tank) but that's a longer story :)

Replaced fuel pump


ther is no reset switch on a gm sorry. this type of pump is very prone to connector connections below the pump to burn the connector. most delphi or other good quality pumps will come with a wiring up grade kit to cure this problem. make sure with the key on cranking you should have 12 volts at the pump connector.
