it is a communication error with the ecm from the ignition switch here is the code description
GM Number U1000
Type Network - Manufacturer Controlled DTC - Manufacturer Controlled
Description Class 2 Communication Malfunction Conditions
DTC B1327, U1300, U1301 and U1305 not current (any particular device on the Class 2 serial data circuit will support some subset of these codes), the ignition switch position requires serial data communication to occur, then at least one operating parameter has not been associated with an identification number within 5 seconds after beginning serial data communication (a default value is used)

It sound to me like the starter solenoid is bad. If you can remove the starter yourself you should be able to repair the problem. You will need to remove the terminal cover from the solenoid(be careful because there are wires connected to the underside of those terminals so do not force it.) If you look at the back of the terminals you will probably see that the inside part of the bolt is burned. loosen the nuts that hold the terminals and rotate them so that the burned sections are to the outside then tighten the nuts back. (not too tight because you can break the plastic) You can test the starter before you put it back in the van (after reassembling the starter itself of course) by connecting a set of jumper cables from the battery to the starter. Negative gets clipped to any good metal tab (usually where the mounting bolts go is a good spot) and the Positive cable goes to the big terminal where you first removed the cable from. touch a screwdriver to the smaller terminal and then touch the screw driver shaft to the + CABLE CLIP (not the terminal because you can damage the threads if it arcs) Be sure to have a good grip on the starter because if it works then it will jump. And keep your fingers out of the hole where the gear (Bendix) is because when you bridge the contacts the Bendix will pop forward and will shred your fingertips.

If you cant connect to the PCU I would start there, check every single fuse, and grounds for the computer, If they are all good test with a know good computer!

do not think alarm would cause this do you have a check engine light on?? there is a coolant temp sensor that reports to pcm it could be out of range you need to hook vehicle to a scanner and check the temp that is being reported by coolant sensor when cold and when hot also may want to look at mass air flow sensor also have you even thought of ignition module what symptoms you have sounds just like an ignition module problem

It is possibly that the bedix in the starter is not able to push the gear out to make contact with the flywheel. The first step is to remove the starter and visually inspect the teeth of the flywheel. If they are worn in that spot that the flywheel will need to be replaced. If the teeth look good a new starter should take care of the problem.
Most of the time its the starter and the flywheel is fine. However repeatedly try to start the vehicle when it makes the grinding noise can ruin the flywheel.
