From my rebuild thread on this same forum--
Today we installed the rebuilt fuel distributor on the intake assembly, hooked up all of the fuel lines to the FD, put the injectors in empty water bottles. Plugged in the fuel pump and jumpered the fuel pump relay.
We got all kinds of fuel out of lines #1 & #3 with the air flow plate not being depressed at all. Nothing out of all of the other lines. Pushed the plate down still nothing out of the other lines. Unplugged the fuel pump. Decided to swap line and injector #3 with line with injector #2. Plugged fuel pump back in.
Same thing,..no fuel out of line #3 (now on port #2) but all kids of fuel spraying out of line #2 (now on port #3). We pushed the plate down and eventually started getting fuel out of the other ports (#2,4,5,&6). So ports #1 & #3 are feeding all the time for some reason.
Needless to say we are pretty frustrated at this point. My guess is that the fuel distributor is shimmed incorrect so that ports #1 & #3 are feeding fuel when they shouldn't be.
The most frustrating thing of all is that the fuel distributor looked perfect inside. So the issue was probably just our injectors and maybe rich/lean adjustment.
Not sure where to go from here besides coughing up the money for a new fuel distributor.
Thoughts? Anyone know how to properly shim these?
I found out that other cars had the six port fuel distributor with an external adjustment for each port. Anyone know if one of these would work on a DeLorean? I really like the idea of the external adjustment vs. The shim design.
