Well I finally got it running right, and just in the nick of time. I leave Monday for Delaware so I needed it going as soon as possible. Vosko I thank you for jogging my memory on a few of the items. I did not have a blown engine, the Ballast Resistor for the injectors was bad. Using the haynes manual I decided to go through a step by step ignition/fuel system diagnosis, Once I was sure I had spark, I went to the fuel side. My resistor is still bad, and I am looking for a new one (used) but I was able to temp fix it by jumpering 2 of the leads. The rear rotor was not receiving fuel until then, amazingly I was running on one rotor, fighting the compression of one as well. although the car is nowhere near as powerful as the FC's I am used to riding around in Okinawa, I am happy I am able to drive it now.



Now I just need to figure out how the 6 port linkages are supposed to look when wired open. If someone that has this mod done could post a pic for me I would appreciate it.

Take off the vacuum actuators (4 10mm nuts). You'll see the linkage for each port then and you can move them by hand toward the firewall or toward the air box. Standing on the pass side, you want the left one toward the air box and the right one toward the firewall all the way (both toward the middle of the manifold). Just take some garbage bag ties and tie them in that position. I'll try to find a pic.

congrats! you are lucky! have fun pimping it around https://www.nopistons.com/forums/pub...IR#>/smile.png

I have the acctuators off already, I just am not sure of the positioning of the linkages, one is somewhat frozen and I am not sure of the linkage positions is all

spray some wd40 in there

the actuators are normally closed, so you need to turn the valves the other way. or just turn things until you have no power under 4k

Could you elaborate on this a bit? I have the same symptoms, except it's my front rotor that has no fuel. I can't find info on this resistor in the FSM, could you maybe give a good description of the shape, location, and how you jumpered it? Thanks!

it's on the passenger wheel well, 5 wire gang connector on it.



it's only present on cars with low impedance injectors.
