Drove my 914 to a PCA function yesterday morning, 93f and humid.
After driving on the interstate at 70-75mph for around 45 miles I exited and the motor died. I had enough momentum and coasted into a gas station/convenience store where I topped off the tank and tried to restart the car, no luck. The car would fire, run a few seconds and die then refused to re-start for another 10-15 minutes then the same scenario again. No tools to diagnose or repair. While waiting on AAA for three hours (another story) I would occasionally try to start the car with the same results. Today, car started normally, runs normally. 1974 L-jet, original three bung fuel pump, original location. 500 miles on new tank, sock, filter, ss lines. |

This is a head scratcher for sure!
I was reading on the bird forum about a seat belt interlock under the passenger seat that was designed to keep the car from running if the belts aren’t buckled. I do remember trying to start the car right after I bought it, a buzzing sound from that area. Would the starter work if this relay were malfunctioning? |

The relay under the passenger seat blocked the starter from engaging if the seats were occupied and the seat belts were not buckled. If it has not already been bypassed, I suggest you do it. Connect the Yellow and yellow with red heavy wires. I would also suggest that you find the black with a blue tracer wire on the back of the fuse box, fuse 8 that goes to the relay under the passenger seat. It can come out of the relay plug and ground out on the floor. That wire comes from the unfused side of the fuse box, and it is the circuit that powers the coil. |
