ok i just rebuilt my d series and put a z6 head on... its in an ef. so i cut out the resistor box and ran the wire straight to the injectors with the obd1 clips and injectors. I am using an ef dizzy and pm6 ecu. all sensor and tubes are hooked up. I am using a fpr from a 91 hf or std d15?, but its getting fuel. It seems like there isnt any spark. Its at tdc both the head and the crank. when you try to start it, or turns for a while going chh chh chh chh then it starts going chh chh chh bang, like one cylinder is firing. I changed the rotor but not the dist? can anyone help me out at all? any info im out of ideas. ???? Thanks Shaun
