I've been running an EZ-EFI system on my ZZ-4 equipped FJ-60 Landcruiser for seven years now. Never been entirely happy with the quirky, weather-dependent performance of this system, but I have gotten accustomed to it. I run a Performance Distributors DUI distributor with the FAST "RPM Module" connected to the "Tach" terminal on the distributor. A couple of weeks ago, the engine just shut down while cruising on the highway. I checked my fuel pressure - it's perfect. Disconnected the fuel line at the rail and verified that there is plenty of fuel flow. Verified that I have spark. Checked my injectors with my noid lights, and verified that there is no signal to the injectors. I called FAST, and they walked me through some diagnostics. They said that the problem was that my "RPM module" is burnt out. They said that, even though the instructions say that the connection can be made to the distributor if the RPM module is used, it was not good to connect this way. I was told that I needed a digital ignition box (CD ignition) to assure a good, clean signal to the injectors, so I bought a FAST E6 ignition. When I received it, I tried to figure out how to connect it to the distributor - there are not examples that appear similar to my distributor. My distributor has only two connections, one labeled "BATT," which connects directly to the ignition switch and one labeled "TACH." I asked FAST for some advice on how to connect the E6 to this distributor, and they said "I don't know; you should contact Performance Distributors and ask them." I called Performance Distributors, and the fellow I was told I needed to talk to was too tied up on the phone, so I asked if I could e-mail him and was told that would be a good idea. So, I e-mailed him, about two weeks ago, and included scans of all the various EZ-EFI, E6 and Distributor instruction sheets. I never received even an acknowledgement of my e-mail. I waited a week and e-mailed again - still no response. So I e-mailed again, last night, and asked, very kindly, if if might receive an acknowledgement of my e-mails. Still no response. Anyone have any ideas?
