I drove my 1974 1.8 briefly after sitting for two months in the winter. It drove fine for the mile or so. I went to drive it the next day and didn't get too far before it chugged, jerked and then died. Had it towed back to my house. Inspected all the vacuum hoses, electrical connections and cleaned the air flow sensor and plug. Starts for a few seconds at times and then dies. Other times it won't even start. Had new plugs, points and fuel filter installed about 10 months ago. I can hear the hum of the fuel pump, so I don't think it's that. Mechanic can't see it for two weeks and I would like to get it running. I would appreciate hearing from the 914 community about similar issues. Thanks.

It's a good sign you're hearing the fuel pump with the flap held open. Sounds like the pump is working, although fuel pressure remains to be determined. It is amazing how well these old pumps hold up. Mine is still working as well. A replacement sits on the shelf waiting for the inevitable.
The dual relay in my '75 1.8 is mounted on the bottom of the battery tray, on the driver's side of the tray. Yours is probably in the same place, or somewhere nearby. Here's a picture of what you're looking for. The original dual relay is a silver metal box, part number 0332514102, the next generation is a black plastic box, part number 0332514120, and the latest generation is also a black plastic box, part number F026T00064. ![]() |

I will order one of these dual relays and try it out or at least have one as a backup. Thanks for the stock numbers and photos! |
