First of all forgive my lack of knowledge. I am not new to cars but I am new to 914s. I recently purchased a 1970 914 1.7L. with D. Jet. The previous owner noted that it ran last year but was not able to get running this year. The car is far from perfect but I hope to be a solid start for a EJ20 swap in the next year or so. I would love to get the 1.7 fired up to start taking care of of other issues I am not currently aware of.
So let me start discribing what I am seeing Good Battery- Cranks over good and for a long time if needed Fuel Pump- working well but does not shut off after 1-2 seconds. New plugs New wires New cap and rotor I check the fuel rail and I know I have fuel to the injectors. I am able to fire the car up with starter fluid but ofcourse dies when it is burned off. I have had it runnig several times but is not consistant. I have check the grounds to the batter as well as the injector grounds. I don't know where to go next. Any advice would be appreciated. As you explain your suggestion please don't use abbrevations as I am not framilar with them all yet. Thanks -lance |

pulled all the relays which I have done before and firmly pushed them all down. For some reason this time something was different. I put about 20 miles on it thus far. Run but bucks a low RPM.
Thank you everyone for your help. You all have been great! |

Thank you everyone for your help. You all have been great! Are you talking the round relays on the relay board? Move them around to different positions. This will help rule out bad relays. They can develop bad contacts internally. I have seen small particles of rust that can interfere with the relay coil / armature motion |
