I have a 1982 vw rabbit conv. with the mechanical fuel injection. the car
was runnig fine. It was turned off and when we went to start it again, it
would try to start but would not run. The first thing that I did , once I
got it home, was to put a new fuel pump on. That changed nothing. I then put
a new fuel pump relay in. Still nothing changed. I have also put a new fuel
filter on. I took the constant fuel regulator off, cleaned it, put it back
on. Still no change. I know that the fuel pump is working and the fuel line
pressures up. When I try to start it, the cold start fuel injector operates
(properly I believe). What seems to be happening is that there is no fuel
making it to the injectors. If I spay carb cleaner into the air intake, the
car starts and runs fine until the carb cleaner is used up and then it dies.
I spent quite a bit of time today on the frequency valve. I don't know if it
is working, or if it's working, is it working properly? I don't know what
voltage it should be carrying. I don't know what component tells the
frequency valve to operate. I am basically just guessing at this point and I
guess that my problem may be in this valve. Any hints or suggestions are
welcome and would be greatly appreciated. Thank You.

A 1982 Golf/Rabbit should have K-Jet mechanical injection as you say. A
simple confirmation of the fuel problem would be to pull one of the
injectors out of the manifold, put it into a glass container and turn the
starter. Fuel should come out. A workshop manual should give you the rates.

I don't know what you mean by the frequency valve - if you mean the air flow
sensor plate, which controls the amount of fuel sent toe the injection
distributor, you shouldn't need to adjust that in any circumstances.

My car would not start at one point, and IIRC there are 2 fuel pump relays?
Any how a 12v supply from a headlight to the fuel pump was enough to get me
home, until I could get a new relay.

Here's a quiz question for you - I've got 2 K-Jet cars with 10 cylinders
between them - what are they?

Good luck

Jeff, I know that this sounds stupid, but this is my first time dealing with
any fuel injection. I'm not sure if I need a special tool to pull an
injector or not. Looking at the injectors, there are two fittings together
at the engine. the top fitting is a 14 mm and the bottom fitting is a 12 mm.
these don't seem tighten nor loosen. I'm afraid to mess with them much while
being ignorant to the proper removal proceedure. All that aside, the engine
will start and run well when gasoline or carb cleaner is sprayed into the
air intake assembly. Any further ideas or suggestions is very welcome.

Sorry to pick this thread up a bit late, and probably miss a lot of the
points made, but my recent similar experience was fuel related on a Golf 89
digifant. First - 2 fuel pumps, one in the tank, one under the car, check
them both. Fuel still comes through at a rate of knots even if one pump
fails, and the circuit still draws upwards of 8 amps as the remaining pump
works overtime. Second, one relay covers both pumps. you really need a
Bentley manual to figure this out, and they explain how to short it and
isolate if it's at fault, really easy. Third, to check the injector I think
they just pull off, and you put it in a milk bottle. Fourth possible
blockage, usually filter. Mine was under car fuel pump - easy job, but £40
s/h, and change the filter while you're down there.

Does it try to start when you have the starter engaged but just die then ?
Tim

Yes Tim, it does. However, as the engine starts, the rpm's exceed the
starter and it will disengage automatically as it should. As stated
previously, it will start and run if I spray fuel or carb cleaner in the air
horn between the fuel distributor and air intake manifold.

Did you check my earlyer suggestion about coil voltage ?
