Ok that's right! It must be stuck I would try to clean it with soap and water and water pressure and see if you can get it running off the car then rinse it with 90% rubbing alcohol and paint thinner. Is it pulling current? Making a spark when you hook up the 12 volt wire? BE Careful though! Better to do that test away from the car after washed with soap and water. _________________ 1960 Beetle And 1679cc DP W-100 & Dual Zeniths! |

I took the fuel pump off and cleaned it up and saw the + and - signs. When I reinstalled it I put the red/blue on + and the brown on -. As I knew I'd be unable to sleep without a better understanding of where the next problem may lie, I took off the cold start valve and turned the ignition on. No fuel came out, so I disconnected it fully and still no fuel.
I climbed underneath and verified I see fuel in the fuel filter, fuel pump looks good. I then took a test light and verified I'm getting power under there when cranking. But I don't feel the pump turn on. Maybe the pump is fried. |
Put the end of the hose to the CSV in a bottle and depress the flap in the AFM while the key is on. It'll never run the pump unless the starter is cranking or the AFM senses air flow, depressing the flap simulates that. _________________ Rust NEVER sleeps and stock never goes out of style.

What is CSV? Only familiar as a file format. |

Ahh. Sorry I knew that. When I tested it yesterday I even pulled the fuel lines running to it and they were bone dry that's what led me to the fuel pump.
I'll give cleaning it a try this evening. |

No need to clean anything yet, right now you are testing the fuel pump, aren't you? _________________ Rust NEVER sleeps and stock never goes out of style.

I meant cleaning the fuel pump cause I'm pretty sure that's causing an issue. |

Evilrift I am sure busdaddy has the best handle on the electrical here for your fuel pump but you said you did get a test light but no fuel so it probably is the pump not running or perhaps your not getting fuel from the tank to the pump. _________________ 1960 Beetle And 1679cc DP W-100 & Dual Zeniths! |

Ok I installed a new fuel pump, so made some forward progress as I could actually feel the fuel flowing through the lines and now it tries to start but just won't catch.
I guess I'm back looking at timing? |

Ok, I'll try that again. I'm pretty sure I just tried it there. I was confused about the notch in the disti, I read that it points to #1 but I thought it was referring to the actual cylinder which made me wonder how I got the disti in so wrong.
Everything all wired up.
Pic of the disti, when at 0 on the timing chart.
I'm recharging the battery before giving it another go. What would be the next step? |
Did you set this again. after you tested the points with the test light.
Fan timing mark on (0) rotor aligned with notch. It should start.
Don't forget to run at 2k rpm for 20 minutes to break in the cam! |

Yep reindexed it there but it still just won't catch. It comes close. I'll have to try gas down the boot again to see what happens. |

Cranks over great. Starter seems strong, the battery is brand new and I keep it charged.
I think it's fuel related and will try to get a fuel pressure gauge on it tomorrow. |

So I got a pressure tester on her today and have good pressure (38psi) that holds steady. Still won't fire up.
I guess its time to pull an injector, there's another thread around here where someone mentioned that 1979 Injectors maybe different, is there a way to tell which injectors you have? Ratwell just states universal 022 906 031. |

ratwellThere two versions: 11-pin and a 13-pin. The 11-pin version is the original that was used in 75-78 (and 79 Federal) busses. The 13-pin version was used in the 79 CA bus and the early aircooled Vanagons. The 2 extra leads of the later style was due to the fact that the 79 CA ECU didn't require the series resistors anymore (it used only the resistance of the harness) and it had to power the electronic ignition model. If you fry the relay purchase the correct one for your bus.
The part numbers in the photo are the original part numbers. These are the part numbers:
071 906 059 1975-78, 1979 Federal (Bosch 0 332 514 120)
- superseded 022 906 059 (Bosch 0 332 514 104)
071 906 059A 1979 CA (Bosch 0 332 514 125) |

Ok, verified that the wiring matches and I have the 11 -pin version.
Still will need to verify the injectors are firing, they were sent to Cruzin so I assumed they'd be good but who knows.
I verified they are getting power correctly with a noid light.
Really would like to get her fired up, I've noticed I have a very hard time turning the motor over using the alternator pulley, it does seem the belt has slipped a bit and I'll need to tighten it yet even without all the spark plugs it took some effort to turn the motor. Is this normal? |

A new engine is always a little stiff, any grinding noises when turning? _________________ Rust NEVER sleeps and stock never goes out of style.

Nope no grinding at all. I heard some squeaking recently, which I assume is the belt. But any and all weird noises are freaking me out. |

Tightened the belt and the squeaking stopped. Phew.
Still can't get it to fire up and stay running. Tested the fuel injectors 1/2 and they were good. Nice spray and power.
Starting to get very frustrating. |

First of all I think the problem is the name of this thread! Perhaps if you named it. Finding the Bright Light or something! Your at the end and it still doesn't start up.
But. Just start over and review what has changed between when it did start and when it would not start. Chances are there is something there we are missing. _________________ 1960 Beetle And 1679cc DP W-100 & Dual Zeniths! |
