It simply needs to be grounded to the body of the car, or on the manifold. Make sure it has a good connection. I have an 83 ZXT engine in my 240z, not to many wires that have to be done really, which is good

OK, so I swapped in a normal blaster coil into the system. I check voltage on the positive terminal to ground, 8-12 Volts (battery getting weak) Power across the terminals is 0 with switched power on, and when cranking.... NO Idea what to do now...bad ecu?

Ok the bug got to me, went out and tested everything... I do have fuel pressure.... The issue has to be with the coil wiring at this point.... I can post pictures if this will help...

The only X factor I can see in this swap is that I am running a Z31 Blaster... I mean the wiring is fairly straight forwared on this setup. Hook up AFM, run additional lines to to coil +/- Again if I hook the old ecu in I do get spark, and the dist makes a ticking noise for a few seconds...there is an obvious absence of that now

Injectors are firing, I will check the fuel tommorow. Im still not confident the Dist is firing correctly

Ok I installed the chopper wheel.... I checked the voltage from pins 34 3...when accs are on I am getting around 10-12 volts....engine turns over but still not starting.... ECU also has a green light coming on I did not wire the FPR as noted in the instructions as this was done with the engine swap, pump is on and running as it should be. With the old L28ET setup after cranking the engine you could hear the dist click for a few seconds...that is not the case with current setup... Original Dist wires are wired as they were for swap, with the additional wires coming from the ecu as noted in the insturctions.... I am sure it is something simple at this point....Help!

Ok Im going to go out there and swap the chopper wheel and see what happens So I will re run from pins 34 & 3 and leaving all existing wiring in tack. Crosses fingers

I have a chopper wheel that I can swap in.... Got dark on me tonight, my understanding, and correct me if im wrong was on the 83 Dist. there was no need to swap the chopper wheel.

Well I have been reading over the diagrams now for 2 days, and I have tried everything that I can think of to resolve the issue at hand. Here is my setup 240 w/ L28ET Turbo swap 1983 - Engine & Harness Z31 Coil MAF was Wired in ECU Z31 88 NA (Will be reprogrammed later) ----------------------- I have followed the guide and I am connecting the ECU to the 83ZXT harness... Car has no spark.... If I reconnect the 280ZXT ECU, I will get a spark. I have added the additional pins as needed, connected metter to pins 34 & 3 and I am not getting a signal, hence no spark. The Wires to the coil are hooked up to the harness as they were when I was running the Stock 280ZXT setup...., I have attempted to disconnect and wire to the ecu as well. Do I need to modify the harness and move the pins that are causing it to fire on the 280ZX setup? Anyone in the area want to help?

Well, I finally decided that I am going to keep my 73 240z.... For the most part the car is in excellent condition.... Nice straight body.....but obviously with a car of this age there is some damage... The floor needs to be reselaed (from below the car)....there is a whole in the firewall/fenderwell under neath the battery...and I may have to replace the core support...(it is straight but there is some minimal damage on the pasanger side)... Anyway does anyone have any recomendaions on where to send the car...or anyone who is interested in in this kind of a project? I am in Southern California...
