Hi guys, Chris from New Zealand here....finally bought myself a 914! Shes a '73 2.0 with original FI. Had her about a week, after standing for 8 years.
Previous owner spent some time and money getting her on the road as part of the sale to me, but still a bit of work to be done! I'll try and attach a picture. Took her for a shakedown run today for about 3 hours but then she started coughing and spluttering then stalled at about 60mph. Coasted to a halt, ignition on/off and away she went again for about half an hour.. Same thing again, ignition on/off and all was well for another 20 min.. This went on and on and the intervals between spluttering and stalling got more frequent until i just about made it home. Felt like fuel rather than electrical... Could it be the fuel pump, or any other ideas? I have a feeling I'll be using the forum quite a bit (IMG:style_emoticons/default/smile.gif) Nice to meet everyone! |

Beautiful car. Welcome to the World (IMG:style_emoticons/default/beerchug.gif)
You may want to start learning about D-Jet. It's an old but reliable FI system, but like any other system the parts all have to be serviced. If the FI is 'original,' as in hasn't been maintained, you'll definitely want to go through it. Good reading: https://members.rennlist.com/pbanders/DJetParts.htm For the issue you had specifically I'd start checking to make sure all connections are secure. That includes the ground points on the engine and the relays and connections at relay board assuming it is fuel delivery and not electrical. Could also be blocked filter or line somewhere along the fuel path. I've never experienced vapor lock as far as I know (my fuel pump was already moved from stock location) -- can that happen while cruising? I would think the constant flow of fuel would not allow it to "boil." |
