[91422.7]

Having problems getting the starter to engage! I have a 1970 Porsche 914 which I've just installed a 1975 914 2.0L F.I. engine. I've attached a photo of the starter hookup. It appears from the starter solenoid there is a blue wire or red/black wire that suppose to go to the ignition switch! Does that wire actually go to the Fuse Relay Block Panel first then on to the ignition switch? Question #2: from the picture you can see the Air Aux Regulator which has 2 outlets, one comes from the air breather, where does the other one go? Question #3: One of the injectors slides in and out pretty easy, the other 3 don't, is that because the one has a faulty inner rubber seal? Question #4: Is there a problem using the 1970 Fuse Relay Block (Engine Compartment) since I'm using a later model (1975) 2.0L F.I. engine or do I need to upgrade to a FRB out of a 1975 914? Thanks again for all your help!

Hi - Sorry to resurrect an old thread but I'm having a similar starting problem which I think is due to a voltage drop between the ignition switch and the starter solenoid (yellow wire). It starts sometimes fine, but other times there is a short delay with the key held in the 'crank' position, and sometimes nothing at all. I was thinking of installing a 4-pole solenoid to eliminate the problem which I have done on a VW camper with success, but am just thinking of trying to clear any poor connections first. From what I can see the yellow wire from the starter solenoid goes back to the Regulator Plate. Please see attached a pic of my plate which is in a pretty dirty condition. I just wondered if anyone could tell me which wire/plug goes from the Reg Plate back to the ignition switch please? Also I should add that the car has been converted to carbs so thats why not all wires are present on the plate.
Many thanks
