I just saw your newer post..or the original post with more information available. Your K1500 has the ignition switch positioned on the steering column. The switch is control via a linkage rod that is actuated from the key cylinder.(which may have failed.) But I suspect your problems may be in the switch itself. See the procedure here at Just Answer Chevy to remove and install a new switch: Fix Your Chevy With Your Own Hand PS: After removing the actuator rod see if the lock cylinder rotates freely...if it does the switch is the source of your problem.

it could be a bad slav clinder

Yes, it can be the relay. What I do is unplug the relay and swap it gor yhe horn relay. If this doesn't work, I use a volt/ohmmeter to probe the relay socket. Doing this, I can usually find the problem. With the key on , there should be two terminals in the socket that have battery voltage and one that is grounded. The last terminal goes to the pump and should show low ohms to ground. In your truck, the relay coil is connected to ground and turned on by the ecm with a positive signal. It also seems to depend on the oil pressure switch, so you might want to temporarily bypass the switch with a paper clip in the connector to see if that is keeeping the pump from running.

Like your brakes are locking up?

There are no vaccum hoses unless it is a TH400. The standard 4x4 overdrive trans could have a hose to the vent on top of the trans.

Hi Russell: I'd start by looking for a vacuum leak, often associated with the PVC valve. Make sure the PVC valve is not obstructed. Possible dirty air filter. How long since regular Preventive maintenance was done? Cheers

Check the exhaust pressure at the tailpipe of your truck while engine is idling in park or, neutral by covering the tailpipe with your hand if you feel very little pressure your catalytic converter has failed (acts like a potato stuffed into the tailpipe)
