Posted by: wolfeman1727 Jan 23 2013, 11:45 PM
Hi all,
I am the ecstatic new owner of a slightly neglected 1973 914, 1.7 model which someone has put a 2.0 in.
I got the car with first gear problems and ended up having to take apart the tranny and replace the first gear synchro and dogteeth... which I did myself successfully with out terrible difficulty. I got to Drive this sweet little thing around for about a week and the engine sputtered and died on me.
It doesn't get gas
-replaced the fuel pump
-replaced the filter
still no avail
The leads in the fuel pump plug read a laughable .2 volts when the ignition is on and the engine turned over.
Im not getting the power
-replaced relay
-cleaned all connections on the regulator plate
Im getting 12 volts across the leads attached to the relay, but the relay isnt closing my circuit.
Any Ideas??
I miss driving the darn thing!

You may have a bad relay board or a bad replacement relay. Take a relay from one of the headlight motors and try that.

Fuel injected? If so, the ECU ("brain") grounds one pin of the relay to run the fuel pump. It will do that for about 1.5 seconds when the key goes from "off" to "on", then again while the starter is cranking, and also when the engine is running over about 50 RPM.
That assumes the D-jetronic injection that was originally used on all of the 1.7 and 2.0 914s. The 1.8's L-jetronic injection ran the pump when the flap in the air meter was opened. Carb setups will typically run the pump while the key is on, but that is up to the person who converted the car to carbs.
Brad Anders has a troubleshooting flowchart on his D-jet site: http://members.rennlist.com/pbanders .

Are you anywhere close to Paso Robles?

All the connections on the board looked good, and I swapped several relays just for fun.
I will confirm connections on the plate with a meter tomorrow and see if there are any issues there.
The system is definitely D-jet

I'm currently out of Stockton, Paso Robles would be a little bit of a drive haha

There are a few of us that are within 30 minutes of you! I am in Discovery Bay and at least 4 others are close too! If you need some eyes I am sure we could find someone to come out help you get it going again!
It sounds like your relay or your Fuel Pump is having an issue.

Come on wolfeman! A new owner post with no pics. A picture is worth 1000 words.

ALRIGHT, alright... here's a picture of the new obsession

although rare, the brains do go bad.
my '71 1.7 was down for months as i tried to diagnose issues similar to yours (no signal to the injectors when cranking the motor, in my case).
after i broke down and took it to a pro, he spent hours covering the basics before swapping an ecu from a running car and she started right up.
good luck and let us know how things turn out.
oh, welcome to the madness!

I'm Going to try and do a little more investigation and research for now, But I greatly appreciate the offer, and may take someone up on it soon.
I'll let ya know

Filter Inside the gas tank plugged? Run the pump out of a gas can to see if the tank/ line is plugged up.
Old gas varnish plugging up injectors or carb jets?
Temporarily run a hot 12v wire to the pump?
Great looking car!

Do I spy vinyl A pilars? Is this one of those 1000 Ca cars?
As for the fuel pump problem. If it has the original factory wiring. Brown is ground to the fuel pump. I would get a small 5ft jumper wire from the battery and go directly to the + side of the pump to verify the pump works.
Step 2. Remove hose from the in of your filter. Gravity should push down the fuel in the tank and spill out. If not then u have a bad fuel line. Obviously this step will only verify fuel to the filter, not your voltage problem.
Good luck

Looks like one of the elusive 1000 first of '73 ...

I'm afraid there isn't any vinyl on my pillars, this car was factory white and was painted...sloppily

The tank was just filled up when I developed this issue... and it all drained nicely from the hose attached to the pump... no clogs or bad lines.
Im pretty confident my lack of voltage is the issue at this point.
Time to double check all my fuses and connections

When I lived in Ca (Compton to be exact) this kind of paint jobs were popular

After much touching, unplugging, testing It started right up...
We bypassed the relay to test the pump, which worked beautifully... and then re- installed the relay...and the dammed thing worked.
I'm back on the road for now 
Thanks guys!

oxide on leads that you cleared up by unplugging? splice somewhere in the wire to the fuel pump that won't allow power through (intermittent)? i hope the gremlin stays gone.
