Hello,
I recently bought a 1973 Porsche 914 with a 1.7 and fuel injection. The car ran ok when first purchased, However, I went to start the car, it would not fire up. Got spark etc, but no fuel. I noticed most of the fuel injection wiring harness is brittle and or have cracked wires. I have tried cutting out the old wiring where I can, however to no such luck.I would like to keep the car fuel injected, however, I can't find where to buy a new wiring harness and or don't want to assume that is the only cause. I recently have been discussing with other past owners of the 914 and two have said to go with Dual Weber 44's or 48's? if I went this route, do I need to change out my distributor and Cam? I know the fuel pump will need to be replaced. I would like some input and or advise from someone who may have already traded out the fuel injection for carbs. Lastly, Im an old VW guy and know carbs but the wiring on this fuel injection seems it could take me down the rabbit hole to more problems and cost. Thanks Mark |

From someone who loves running carbs this is what i would do.
1. Contact Jeff Bowlsby and get a new fresh harness 2. Install harness and continue to diagnose - tons of help and info out there. FI can be difficult but with a methodical approach you can replace each piece to diagnose the issue. 3. Throw in the towel so you can drive the damn thing and purchase a set of weber 40s, 44s on a 1.7 will need to be choked down a lot. |
