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.

I had this happen to my 74 1.8L recently. My original dual relay went out. I put in another known good used oem metal dual relay and my 914 roared back to life. I now have a few of the newer plastic dual relays set aside ready to go along with a few afms. I've started to collect anything related to the FI system for these cars. I also recently replaced both the FI harness and ignition harness made by Jeff Bowlsby to replace my 50+ year old harness. All if not 99% of my electrical gremlins disappeared related to the FI system etc.
