Fuel injection relief here!

[Deacon64]

Tram,

Browsing thru the acres of advice you have given out actually gives me hope. Preface: I'm not too mechanical, but not afraid to try and I have never worked on an aircooled engine before.

I have a 71 squareback. Love it! 2 weeks ago I got rear-ended in a hit and run. She ran OK, just mangled for about 4 days, then blew the #3 spark plug right out. I took her to a local and recommended VW mechanic, $300 later I had a valve adjustment, a tune up with new plugs, wires, cap, rotor and brushes, and an oil change and screen cleaning. The car started right up, sounded like a VW again, but reeked of gas. The mech told me it was residue from the blown plug and it would go away.

It's been a week, 4 tanks of gas averaging 11 mpg and the gas smell is as bad as ever. Additionally, in the low end of the gears it lugs something awful, like it's flooded.

The mech will look at it, for a price, swearing he didn't do anything at all to the fuel line or injection.

What do you think I should do next? Is there an adjustment I can make? I love driving my car but at 11 mpg it's hard to justify.

Thanks for your help.

You don't need an adjustment; something broke and needs to be repaired or replaced.

Richness can be caused by disconnected hoses (contrary to intuition, an intake air leak causes richness in the FI setup, not leanness as on a carb setup), disconnected wires, or a broken MPS. All of these are possible results of an impact.

Check the engine bay for loose hoses and wires, and then try testing wires and sensors with a VOM.

[Deacon64]

Looking for a schematic of the wires and hoses. I guess you know what I'm going to be doing this weekend.

Thanks again!

Clymer Publications ch 7. downloaded from vwtype3.org, looks to have fairly clear explanations and photos. Actually explained some of the terms you had used that I wasn't familiar with.

Will see what I can do, this is my daily driver, and it's eating me out of house and home.

thanks for all the help. I'm sure I'll be back with more questions.

I am have trouble starting my 1969 type 3 squareback when it is cold it takes awhile for it to start. Once it warms up it starts up fine. What do u recommend?

[Deacon64]

I found the cold start valve... finally. Thanks to some pictures of parts for sale and a little deductive reasoning. I started up just fine, so we will see if it makes a difference. I left the temp sensor alone, I just added some electrical tape to what looked like some broken insulation, the wire was intact.

As far as air hoses... that was not very obvious either... It would appear that the hoses don't require hose clamps? I thought they were pretty easy to disengage, but they didn't look like they'd been touched in over a decade. I made sure they were sealed connected properly, and they were.

Thanks to everyone who has helped me so far... I hope this works, crummy time of year to have your car on the fritz, especially in Utah, it's freaking freezing here.

I've just unbolted the pairs of injectors turned the engine over and watched mine spray gas onto the top of the engine. You can see them working of not. If they spray evenly I might start looking for a different problem?

Just an FYI to all: incorrectly adjusted throttle switches can cause starting issues also.

Does anyone have a chart showing the part numbers for the fi harnesses from different years? I need to know the part # for a 68 "A" harness

" If the OP needs a harness, Joe is the first guy I'd contact. Cool He does great work on them."

Second the thought on the above,he did mine last year works very well!

No cold start valve. The reason I ask is the harness that popped up for sale in the classifieds.

Hey Tram,
I am new to this VW thing and just started a project. I acquired the body and frame of a 63 Notch, so I started looking for a parts car and just pulled a 69 Squareback out of a field here in Oregon. It is fuel injected, and the thought of it terifies me. Might be coming back to you for info.

[Mike Fisher]

Get the engine bolted in the '63 and pay Tram to get it running/driving in Springfield. He did a Hell of a job on mine!
