Question about 1998 GMC Jimmy
Now the crank sensor has no voltage supplied to it its just an induction sensor ,in this case i suspect dirty connections in the multiplug ,test the old one to make sure its working which is easy to do with a multimeter if its failed then its getting a back feed when you shut it off from the ECU and to be honest i think you may need a dealer diagnostic with their special software a code reader will not be able to do this for you ,you could test for this yourself with a decent multimeter ,disconnect the multiplug and read from ignition side with ignition off and see if you get a voltage as this will burn the induction coil of the sensor .

RELEARN MAY JUST BE CLEARING THE MENORY OF THE POWERTRANI CONTROL MODULE, BUT THE CODE INDICATES THAT THE CAM SIGNAL IS NOT MATCHING WHERE THE CRANKSHAFT SAYS IT SHOULD BE, DID U USE THE FACTORY CAM GEAR WITH THE MAGNET EMBEDDED IN IT ? IF NOT THEN THERE IS NO WAY TO TRIGGER THE SENSOR, CHECK THAT.

Are you sure the vibration is from the engine? Maybe it's the u-joints or center bearing. But if it's from the engine, your engine mounts may need replacing. If those are ok and it is your crank or cam, then you need an engine overhaul.

It probably is a fuel pressure regulator. I don't have my books home for this vehicle so I am unsure as to where it is located on your vehicle but you might go to the parts store and ask them if they have one for your pickup and if they could show you where it is at. Most the parts stores will help you out. If not go to one that will. They are all pretty good about helping out.
