Ok, rookie move. My kid had turned the gas heater fan switch on. I didn't even know that I had one.

I have battled the kids vs. random switches in my bus for years. My girl and her friends play in my buses all the time. They turn the lights on during the day when you cant tell they are on,and yes, the fan switch is a classic!
Dang kids! :-)
So is the bus running again, or have we just solved the battery issue?

I was going to guess gas heater blower fan... Anyway your pictures show a fuel injected engine. Some things are disconnected like the EGR valve, but this is not important. Your booster line is definitely attached to the manifold in that picture. All the other visible vacuum lines are attached too. Here is a question. When it last ran, did it backfire at all? Backfires often end up in vacuum lines blown off. Look carefully at all hoses attached to the big rubber "s" boot that connects the throttle body to the air box and make sure the other end of each hose is securely attached. By far the most common cause of buses not starting after sitting around for a while is the ignition points. These have a tendency to corrode if the engine is not run regularly. Have any nasty rats on the farm? This has been the worst year we have ever seen for rat damage to wiring on customer vehicles. Seen any chewed up wires? Give the fuel pump a whack with a hammer before attempting to start as well. Make sure none of your fuel lines have sprang a leak since last time running. Have a look at these items and then report back. Do you have the green Bentley manual in your possession???

Honestly the van ran great.....aside from a weird braking issue that we assumed was the booster misbehaving. We timed the engine, new engine points, bled brake lines etc.....Within a 3-4 week window of me pulling the booster off and putting it back on it never fired up again.
I'll do a good inspection of everything you mentioned and get back to you. I do have the blue Bentley manual.
Thanks guys

Have a look at these items and then report back. Do you have the green Bentley manual in your possession??? So I've looked at all the lines that I think have to do with the vacuum lines, and they all look ok to me. Some dirtier than others but nothing loose or broken. I even pulled the pan off the bottom and traced back the lines from the booster and they look ok, little rusty The only question mark might be the length of the "nipple" on the new booster is a little shorter and the hose doesn't quite go as deep onto it. I have drained all the old fuel and changed the fuel filter as well and while doing that I didn't notice any leaks around that area. If the points were on the frits would I still have spark coming from the coil? I haven't noticed any wires being chewed up either. Is there any way to test a fuel pump without squirting gas all over the place? It's virtually a brand new pump with maybe 2 hrs on it, but when I lay under the bus with my hand on it it only gives a little stutter when the key is initially turned. I also swapped the relay as well, hoping that might help but no dice. Also, never had a backfire incident |

The fuel pump should not run with the key on. The engine must be cranking before a signal is sent to the fuel pump via the air flow meter. Your air flow meter is plugged in? Hard to tell from your photo, but on the positive side of the coil, you should have a wire to feed the backup lights. This wire also feeds part of the double relay so make sure it is actually connected to the coil. The left fuel rail has a small 7mm head bolt on it. This is the port to check fuel pressure. If you have a fuel pressure gauge, connect it here. If you do not you could get someone else to crank the engine briefly and watch for fuel spraying out this fitting. Obviously this is not very safe so be ready for fuel to squirt! Given that you previously started it on an alternate fuel source, the ignition system should be working...

But with somebody cranking the engine should I be hearing or feeling the pump if I'm right beside it? I'm thinking of unhooking just past the pump and trying to catch in a bucket.

Yes you should feel/here the pump humming while cranking...

I would say that it is not running the way it should. I'm laying there with my hand on it while my someone is cranking the key and all it does is give a little kick when the key first turns.

Sounds stuck to me. I have heard that taking it out and running it backwards briefly might free it up. How old is the gas in the tank? If it is old gummed up gas that pump will not be happy.

The gas that "was" in the van was about 2 years old, the last time it ran. I've also read about reversing the polarity on the pump to try and get it moving, anybody had success with this? But with that said, the window of the van driving around to not starting up again was 3-4 weeks.....2-ish years ago
