trying to start

VW_MAN_73 · Posted: Sat Apr 29, 2006 8:43 pm Post subject: trying to start

I just put a new fuel pump in the bus. It is getting spark and fuel and plugs are connected right. It turns over and sounds it starting to run but then doesn't. What is going on. I keep trying it and then letting it sit not to flood it. Any ideas?

i'm guessing you took the distributor out to swap the fuel pump. did you put it back right?

No, I didn't have to take the distributor out. The bus is trying to start but won't catch.

First go back to step # 1, get a beer! Razz

Then revise the basics, firing order, timing, fuel hoses in correct pump port, etc. It's prolly something very simple, so simple it might have been overlooked. Cool

Then get another beer! Laughing

Sorry about my edit, I didn't read the first part of this, I'm assuming it ran fine befor the fuel pump replacement??

Try putting a hand over the carb while someone turns the key, maybe the choke is at fault Confused

Actually this was a motor I had gotten when I had bought the bus. It was a long block really. I put everything on it. It is a singleport motor 1500cc. I have a 34pct carb on its correct intake but had to use the singleport manifolds to work this system. However I bought these intakes used off the site and the manifolds diameter is smaller than the intakes. Usually the manifolds are bigger than the intake. Iam wondering if there is not a good flow of gas due to this setup. if you are wondering about the manifolds, they are the ones to convert to the use of a bigger carb.

I wonder if the gas could be getting hungup inside there going big to small Confused

You may want to try pulling the manifolds off & filing the lower part inside so there isn't a big lip in there for the fuel to get hungup on. Don't know if it will work, but mat be worth a try.

The carb flange on the manifolds are known to "warp" a bit. Check yours to be flat or it may be inducing a vacuum leak. Same goes for the flange on the carb itself! Wink

Fill an squirt oil can with fuel and carefully squirt some down the carb while trying. If it works then examine the fuel line, fuel pipe, needle areas.

Hey guys. I forgot to mention. It is a type 3 motor and it shows in my book that they have a different firing setup on the distributor.
t1+2 t3
3 2 1 4
4 1 2 3

I turned the distributor to where the #1 notch matched the spot for the #1 firing order for type three. and connected all wires to t3 setup. All I heard was some pops. What do I do now? I am going to light this bus on fire and crash it into the woods! Twisted Evil

I don't think that type 3 thing thing comes into play here but I could be wrong. Put the #1 wire in the cap at about 5 o'clock looking down at the cap. Put the #4 wire at 8 o'clock. Put the #3 wire at 11 o'clock and the last #2 wire at 2 o'clock and see what happens. Try keeping that same order but move each one one spot clockwise if that doesn't work. Try all 4 positions. Is # 1 timed right?

You have your rotor in place, of course, don't you?

I had it setup like you said and it won't run. Sounds like it is trying to but doesn't. Also, it is a beetle distributor 009 that I put on this type 3 motor. Is there a certain way I have to put the distributor on, did I install it wrong? There is fuel and spark.

The distributor will only drop in one way. Try the thing I said about moving the wires one notch. Also try this: take out #1 spark plug and turn the engine by hand. Stick your finger in the hole and determine when it is compressing to top dead center. Look at the rotor and that is your #1 wire.

VW_MAN_73 · Posted: Sun Apr 30, 2006 8:20 pm Post subject:

o.k. Barry. I will try that but when it compresses(piston is pushed out) the rotor will be at 2 different spots each time. For instance when at tdc and turning to tdc again the rotor is at different spots.

Take it to a mechanic and get a free estimate on what's wrong with it. Then take it home and fix it. Call me cheap.

bill may · Posted: Mon May 01, 2006 5:40 am Post subject:

on some of the aftermarket fuel pumps,the inlet and outlet are reversed. is pump pumping? if you pour a small amount of gas down carb throat,will it fire? you need to set #1 on tdc then looking at top of distributer firing order is -clockwise 1-4-3-2.. roter points at small notch on rim of distributer and #1 on cap lines up there. too bad you put worst vw factory carburater on a fine single port engine. have your valves been adjusted lately?
