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 |

Thank you everyone for your quick response. I am very grateful for the help (IMG:style_emoticons/default/smile.gif) mepstein- Great suggestion and for the price hard to beat. I want to try one or two more things before I send them out. Tbrown4x4- Just replaced fuel pump with stock replacement. Not sure what fuel pressure is as I don't have a gauge hooked up inline. In regards to the points. They looked OK but to be honest I don't know what a bad set up points would look like. Can you give me any insight in that direction. Is there a way to test and see if the trigger points are sending a signal? Porschef- Sounds like you know somone in Grand Rapids and if so... I would love a local contact Bartlett 914- There was only a gallon or so of gas in the tank when I got it. I put in dry gas and also 4 gallons of 93 octane. Hopefully that would have done the trick for the gas situation and regard to the injectors I think we all can agree they might be clogged. I wish ther was a way to test and see if the injectors are even trying to open. I pull the fuel rail last night and turned the car over an nothing came out. Not a drop. worn- Great luandry list of items. How do I test and see if the fuel pressure regulator or cyclinder head sensor is not working? |
