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! (IMG:style_emoticons/default/pray.gif) |

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 . --DD |
