 |
|
Can somebody help? Bus stops running every time i put in get gear. Engine sometimes shuts down, other time it acts like it's running out of gas. What would cause this? Bus was tunned up before winter (plugs, cap, wires, rotors, points, oil etc...)

Had the same thing and the VW shop replaced the carburetor ($80 w/ labor) and adjusted the timing. Said it was from sitting so long and it fixed my problem. I was also told not to the let the bus set and once you fire it up to drive and not wait for it to warm up. I usually have problems after it sits for weeks for the first few minutes and then it goes away.

Why would you not let your oil pressure/temperature build up?

Sorry about that, I'm starting to get slightly aggravated at this thing and I'm not thinking straight , Its my 77' westy.. 2000cc.. Automatic, It normally takes a while to get it started and now its just pfft dead, and won't start at all. I found this full of yellow gunk, which I asume is from condensation mixing with oil but why???
I also found this unconnected and just laying in the engine compartment

the PCV goes on the top of the breather tower on the case and a hose goes to the S-Boot. The plastic piece with the hose probably goes from the S-Boot to one of several places. Look at the decel valve first. |

PCV i think...it vents pressure from the crankcase into the intake...a long trip (drive for at least a hour solid) would make most of that moisture go away. its from sitting. that same moisture collects in your muffler too, so driving it will give it a chance to dry out and quit rusting internally....

okay, when it doesn't start, spray some gas (or a SMALL amount of started fluid into the intake, and see if it fires....that way we can see if its a fuel issue or a spark issue... if its FI, you may have to do this while cranking to get past the AFM box flap.
then:
test the coil by removing the coil wire and holding it about a 1/8th inch from a ground and looking at the spark as someone cranks, then report to us the color of the spark, if there is one.

Its a spark issue... There is no spark at all from the coil. I tried two different coils so I'm not sure what the problem is/

is the coil getting 12 volts? check the 15 side, or the + side of the coil with a volt meter with the key on.

I don't currently have a voltmeter (I know, I know)... what are the two likely scenarios?
EDIT: Let me clarify that  If it did get twelve volts what would I do, and if it isn't what should I do?
