Frogon Posted July 24, 2019 Share Posted July 24, 2019 Hey guys, I'm trying to finish up a L28et swap into my 1977 280z. engine came from another 280z car that was swapped a long time ago. I got a new harness and wired everything up but I'm not getting spark. When I crank the motor the ECU is getting RPM, firing the injectors, and the FIDLE LED is blinking but a spark plug placed on the valve cover doesn't produce spark. I followed the mobythevan post and put in the drop resistors to the dist and HEI module. The coil + has the condensor connected to the dist, 12v from ignition, and B from HEI. the coil - has the blue tach wire and C from the HEI. How can I test the HEI module is sending the signal correctly to the coil, and then the coil is sending to the dist? Quote Link to comment Share on other sites More sharing options...
