So, I was playing around with my OTC 4000e scanner today after I fixed my TPS (pins were loose). I went into a menu that I shouldn't have and hit enter instead of mode to exit. Then there was a huge backfire of some sort that scared the crap out of me. I looked everything over and tried to start the engine and it wouldn't start. I went through the menus and it looks like I went into the spark test menu. Oops..
I pulled the codes. Had 43 twice. Ignition Coil #1 and #2 primary circuit. Then I had a code 53 SCI fault. :eek:
I pulled the spark plug wires from the coil and checked for spark. It was a little weak, but you could see it spark across the coil towers.
Using my meter I checked the coil primary resistance and had 0.5Ω for both. Then I checked secondary resistance and had 14KΩ for 1&4 and had 15KΩ for 2&3. Within spec according to the FSM.
I pulled the plugs and had fuel on all four of them. So I assumed the fuel injectors were spraying during crank. I then ruled out cam and crank sensors.
I left the plugs out, unplugged the injector harness and cranked the engine a for a few seconds to help clear the cylinders out of any extra fuel.
So I put everything back together and it started. But now I have a CEL on all the time. Code 43 Ignition Coil #1 Primary Circuit.
Now the question I have is, did I totally f-ck up? I think I either fried my coil or fried something in the SBEC. Has anyone encountered something like this before? Anyone have any recommendations?
The car seems to run just fine. Just has the CEL on all the time.
