No matter where I am, at home, gas station, highway, everywhere. Yesterday it wouldn't start. On the odometer it said "no bus" what does that mean? It doesn't do it enough to find the problem, but I am afraid to drive on the highway and it die while I'm towing anything. Please help me.
Well all i know is that there is a power bus line that controls the entrine cars electronics. that wire runs under the dash you can follow the wires from that fuse and shake the wire to see if you have a short or something i had my sah apart and touched that huge wire harness (bus) and my fuse blew...so hope this helps Mike

Amazing.....At this very moment in time.....my 2000 silhouette is doing the same thing....if you were unaware.....ventures Montana's and silhouette are from the same mold. Very similar in all aspects. My diagnostics have got to the fuel pump part of suspects....but I have already checked filter, relays, fuses and ignition electronics....my latest suspect is the pressure sensor that monitors the pressure of the gas tank....there is also a pressure sensor on the injector rail I'm suspicious of. I'm going to find out how to place each sensor in "okay ....fuel pump turn on and pump fuel to the throttle body" to check them. In my case....I don't smell any gas after turning the engine over....trying to start it.....sometimes for over an hour....never any gas smell....so I suspect fuel delivery is the problem. The fuel pump has several sensors that control whether or not it needs to run....and pump gas. I can hear my fuel pump run for 2 or3 seconds when I turn the ignition to the on or start positions.testing all of those sensors is my plan of action for this 3 day weekend. Your on track with your work and suspicion of the position sensors......vacuum leaks will follow the sensor checks. Vacuum leaks could cause a couple of sensors to fail too.....I dropped my fuel tank last weekend....and found the fuel pump to be in working condition.....I removed my fuel filter and punched a hole through it for free flow.....to eliminate it from the list...after checking the vacuum angle....I will move to the electronics side.....with the ignition switch first and the transmission position indicator switch following.....I've plugged my trouble code reader in and didn't get any indication of any failed electronic devices......my problem and your problem seem to be very similar, except that I am doing all of my work on the van myself. I will try to keep you informed of my diagnostics through fix it.it would be nice to know how yours is advancing too.....there are a few directions you can progress into.....hope one solves your problem....if not.....there will be more ideas to come....until I solve my problem....good luck to. Us both and onward we go......Nick.ps couldn't spell or grammar check because I'm using my phone to compose....and the typing pad covers the entirescript being typed. Sorry for any problems.

sorry but sounds fatal. bearings are siezed therefore battery voltage isnt enough to rotate the engine. THIS IS BAD. new bearings alone wont fix...probably less expensive to replace engine with a warrantied salvage engine.
You probaly burned out a fusible link. Look for a red wire that has a short piece of black wire connected to it. That black wire may be burned. It may be near the big stud on the starter or near a main junction block.
If you don't do much highway driving with your van you may have a carbon build up try some fuel njctor cleaner and mid grade gas for a tank or two If you go with the fuel additive rev your engine and watch for moisture and carbon from your exhaust contine to do this till exhaust is clear do not over rev ie do not hold it to the floor press he accelerator pedal and release
