Hey, I just got a 88 turbo that needed a new headgasket. It started up fine but there was a bhg. so I tore it all down and put a new oem headgasket in and all other top end gaskets. Put it all back together and now there is no spark. I checked all wires and grounds and all is good. I checked fuses and all are good. I tried a coil pack off another supra and still no spark. I checked my diagnostic codes and it came up with code 51. Will someone who knows what could possibly be wrong please help me! I am so frustrated and I just want to drive the car LOL.
