Good morning.
Am a bit confused about the function of the trigger points in a 914 - 1.7 liter - 1972 Thought their only function was (is) to prevent engine overrun at more than 5700 rpm. This confusion comes from the fact that on the market I can buy Delcos without those points and are being advertised as suitable for a 914...? Anybody can shine light on this matter ? Thank you (IMG:style_emoticons/default/biggrin.gif) |

Does your car have fuel injection? The FI system uses the contacts (trigger points) to fire the injectors and turn the fuel pump on. If you have carbs then the contacts aren't used.
The trigger contacts in the distributor are the only way the FI ECU knows the engine is rotating thus turns the fuel pump on (if contacts are open/closing) and turns the fuel pump off when the contacts are not transitioning. |
