Hey folks, I have an issue that I need help with. I was running the car after a little maintenance it died. I now have P2300 and P2303 (P2300 Ignition Coil "A" Primary Control Circuit Low/ P2303 Ignition Coil "B" Control Circuit Low). It cranks over but won't fire. Checked, and all fuses are good, and it has a new battery as of today. It was low on fuel during all this so I added a few gallons (fresh) still no luck. Please give me guidance.... Bryan
A few things to check.. If you pulled the plug wires, did you put them back in the proper position? Are the plug wires fully seated?
If what Nathan says checks out still have codes...pull the ignition coil and check the bottom if its white (see picture below) it is dead. If its black its good and then if its grey its inbetween.
How many miles since the last time you changed plugs and do you have another set of plugs laying around? Swap out the plugs and report back
Did you clear the code? If not it won't clear on its own. The ignition system on the MINI is simple....plugs, plug wires, and coil.
Sure did, and the code(s) always come back after failed attempt. ...and in my foggy memory, I had a P003X initially after it died. HO2S heater Control Circuit High, unfortunatly in my haste, I erased this before I wrote it down. I don't know which sensor it was. What I do know is not much, and I can prove it. Bryan
The one your foggy about is not ignition related its emissions related (o2 sensors). The ones we are concerned about are related to ignition system. Coil, Wires, Plugs. Stock coil or aftermarket coil? How many miles are on the car? Stock wires or aftermarket wires? How long ago have you changed wires?
OEM wires reset code, nothing. It acts like it's out of gas, fuel pump is working, I need to see if I have spark...
Was this ever resolved? I am having a similar issue with my R53 and not sure where to go from here. Was this issue ever resolved and do you remember what happened?
I went through this on an '03 Mini R50. Turned out to be a bad resistor in the ECU. Sent out to SIA Electronics for repair and 3 days later and $220, everything worked fine again.
Welcome to MA. Thanks for posting. How did you find the problem? I have a ABS unit I need to have repaired.
process of elimination. For the Coil pack, you can test the resistance. I then checked continuity between all the injector connectors and the harnesses. Last was to check the plug lead wires. Everything checked OK, so the ECU was the only thing left. For the ECU, I sent it to SIA (http://siaelec.com/) and they ran a diagnosis based on my reported problem. They found and repaired the transistor. They also work on ABS modules, so I'd give them a call. Turnaround was 1 week.
