And to finally break down in a friends driveway. The OP has some serious luck on his side.

Yuch,
Someone added a relay for a starter problem. Likely a no crank hot problem. Here is what I notice. There is a smaller dangling wire red with a black tracer. I'm pretty sure it is supposed to be on the starter solenoid. It has something to do with providing power to the ECU? during cranking. I'd have to get my manual out and trace.
The wires on the hall distributor look terrible. Also, have you followed the brown wire in that harness? It needs to be grounded for everything to work. Good luck dealing with those alternator bolts. I watched a good video on you tube the other day on how to remove broken bolts.
Overall, I'm surprised you have gotten as far as you have. VW, did their home work. From what I've seen, I'd be afraid to run it around the block on a test drive. |
I think the red wire is for a GoWesty auxilary battery isolator that a previous owner might have installed. I connected it in the past and I could hear it click on and off under my seat. I don't think it is a game changer for starting.
Yes, she is dirty and it is embarrassing. I am a traveling rock climber and I was down in Las Vegas, Cali, and souther utah off road often to get to the climb sites. I broke my CV Axel then and drove to GoWest to get proper replacement joints (fyi don't buy the ones off of amazon, even if desperate).
I thought that leak was from my vancafe coolant line coupler area in front of the starter, but ill have to find the source, but it could just be gradual minor leak from driving 4,000 miles in the past 2.5 months. It has been warmer today to clean it up.
As for the alternator bracket, should I skip on drilling those bolts out?
Will verify fuel and spark once I sort the alternator.
Thanks everyone!

huh. Sure looks like the wire that tells things to go when you turn the ignition, but I have been wrong before and will be again.
I have the GW aux battery kit (unfortunately, I have spent way too much time in the past 6 months considering replacement options) and maybe older kits were different, but mine definitely did not have any wires going back that way, everything wired between the kit under my seat and the dash area. or, the PO made his/her own system on your van.
Good luck! You're showing a great attitude on this thread and that's 1/2 the struggle IMO.

According to the manual for your year, that wire does no show up in the diagrams. It's definitely a factory wire. Checking the wiring for the camper, they show a "50" wire for the relay under the driver's seat. I believe it supplies a ground through the starter solenoid that disappears while cranking. They show the T connectors up front, not at the starter solenoid. The manual is not always 100% correct.
The AFC vanagons did get power to the fuel pump relay while cranking.

Attach chain to that wiring, put a 50 pound anchor on it, and throw it overboard
Whoever did that wiring didn’t do you any favors , and you won’t do yourself a favor trying to fix it. Start fresh

In Brian's defense, he just drove through a large East Coast Snow Storm a day or so before.
A lot of that wet "oil" is actually wetness from salted highways.
Yes, the wiring needs cleaning up for sure.
But as a young man I often got a car, jumped in and off we went! Destination California, or Florida, or Maine or somewhere.
Each night as we camped, I'd fix something. By the time I would get home, I had a better car than I left in!
Now, fast forward to today? I'm with you guys, I'd worry about going to the grocery store as that unit sets.
That's why I've got a non runner Vanagon in my driveway, a basement full of new parts and a crying near empty wallet!
Anyway.........
You know what? He's young!
I certainly can't throw any stones for I've lived in that glass house of driving unknown and less than perfect rides on extended journeys.

| Your running out of fuel may have accentuated the problems that ethanol laced fuel is known to cause, both your injectors and valve stems may be sticky.

Why is this an option? I don't know why you'd add 2-cycle to the gas tank. Please educate me.[/quote]
If you have a sticky heater cable or door latch you might spray it with lubricant to get it to work, the same goes for the sticky goo that can build up in injectors or on valve stems, you may need to get lubricant to them to get the component to work. Adding 2-cycle oil, synthetic motor oil, of some lubricant to the fuel in the tank may do the job in this case and costs very little. A full quart of 2-cycle added to the oil will give you a mixture rate of ~60:1 so will likely cause no smoke or fouling problems.
Since he says he has new injectors this may well not be the fix he needs though.

Update:
SPARK: Timing gun shows spark at all plugs.
Fuel: Pressure is felt after fuel filter and new injectors bought from EVWparts were installed. Still waiting on new fuel lines and fuel pressure inline gauge.
Tried to replace the relay by the starter shown in previous photos, new relay killed all crank, put back old relay and it cranked. Put red wire on the pin below the black, no difference.
After replacing injectors, it sounded like it wanted to start on the 1st second of the crank.
Could this be an Air Flow Meter issue? Got a new multimeter, will check pins in ecu plug for resistance.

Have you tried starting fluid recently? If you have spark then it should run a few seconds on a shot of fluid.
Just because the timing light works does not mean that the engine has a good spark, the coil may have enough to trigger the timing light but if the coil is failing it could be delivering a weak spark. Easier to see if you pull a plug and ground it to test for a good strong spark.

Since your starter is cranking the engine I wouldn't worry about it for now come back to that mess later.
What I suggest doing is using either the Bentley or the digijet pro training manual to do a total check of the entire ignition and fuel delivery systems. Do each step completely and keep notes, if stuff is not right fix it as you go but don't stop, even if the van starts up. You'll learn a lot and most likely get the van running, maybe better than before.
I gained a lot more confidence working on my van after I did the above a couple times. I do this systems check annually now and really like how the notes track over time. It only takes a couple hours taking my time.

Pulled the sparks and they are gunked, especially the right side and closest to passenger seat spark. They were new last week. It cranks now and almost sounds like it wants to go, a fast choking.
Will run bently fuel and spark tests if it doesn't go after letting it air out with the sparks out and new sparks.
Any idea what this wire is for, I grounded it as it is brown. It was ripped and beat up when I found it near the tranny area.
Also found that one of my accelerator switches was broken off as well, not sure if that is a recent thing from messing with it:

Well I'll be darned Dave. I was born and raised in Stroudsburg, Stroudsburg High Class of 93.
You wouldn't happen to be the same Dave that had the epic VW graveyard up by Shawnee would you? If so, you did some work on my 74 Super Beetle back in the day.

Is that green wire with all the exposed copper strands sticking out from the electrical tape below the brown wire attached to your oxygen sensor?
You may have multiple, uh, opportunities to improve the performance of your van.
Also, if you're anywhere near Crystal Street in East Stroudsburg, and if (a really big if) it's still in business and owned by one of his sons, Tony's Pizza was the absolute best when I lived back there. Please forgive my trip down memory lane.

It is not attached to the green o2 sensor wire. It is separate, guessing it is maybe oil pressure or temp wire, the blue wire, not sure but I don't think it is a game changer for starting. I ground the brown. Will sort out o2 sensor wire when I can.
