RobTune - no spark on 3/4 cyl
Posted: Wed May 21, 2014 12:06 am
Alright so check this out.
Picked up a SS that had been sitting for two years. They put 550cc injectors, td05, and RobTune in. They couldn't get spark, and so the car sat until he sold it to me. I got it home, and figured out the ignition converter had 1 wrong wire. The 12+ was grounded instead of powered. So then I switched it and got it to spark, but only on 1 & 2. I triple checked the wiring, and even re-timed the timing belt twice to make sure timing hadn't jumped for any reason. I pull the robtune out and put the wires back to stock and it sparks on all 4. Well then I pull the Injectors to put the stocks back in and find NO O RINGS in the manifold for the injectors lol. So it was a bit of a mess but i'm working on it..
My question is, anyone have a problem with their ignition converter not sparking 3 & 4? What else could have cause 3 & 4 not to work? I emailed Rob, but wanted to post here also.
When cranking and trying to fire, it seemed that the firing order may have been wrong as well, it was popping out of the intake manifold and a little smoke, which make me think to re-time the car but am also thinking firing order..
Any help appreciated.
