Bought my wife her first mini yesterday 2004. She has been after me for a long time. Got a deal on it (1200.) due to the fact that it did not start. The young man that told me that it needed ECU, he said that after installing a aftermarket radio the car would not start.(pic of harness he cut up)
Checked all fuses F5 has no power and the pic on the back of the panel looks like guadeg'es but searching the old inter-web some one said its starter (don't think so) another says ac fans? So I repaired the harness that he hacked up ( sodering and shrink tube) and re installed the factory radio. Then reset the ECU using test 21. Still wont start.going to check neutral safety switch tonight, and see about jumping starter to see if starter is good. was looking into ECU being bad found a place in Fl 375.00 to repair ECU if it comes to that. Any ideas would be welcomed something i didn't think of.

 

I absolutely hate when people butcher in aftermarket radios! Sheesh, this person had no clue, when he "modded the wiring harness!"
Keep us posted on your progress and what it took to fix it!
He may have shorted something in the ecu, sadly, that can be a PITA to get worked out!
Re-programing the ecu is a tricky operation, that has no area for mistakes and requires a 90 amp battery charger and a rock solid internet line, with dealer quality programming tool.
There are a few reputable companies doing that.

 

 

So i have checked all fuse power to all but F5 ( 5 amp ), don't know what it goes to. Looks like gauge's (emblem on inside of fuse cover) All dash lights work. Oil PSI pegs out when i turn on ignition. Is that suppose to happen? Key FOB locks doors. No noise when I try to turn it over. Going to try to jump starter relay tonight and see what happens.

 

Does this car have an 'added' oil pressure gauge as no oil pressure gauge came stock, just an idiot light. If it does, the wires on the gauge from the sending unit and the power source are reversed.

 

Welcome to the forum

My God did he butcher those wires

 

Where in NC you located?

On fuses, item # 23 in the below thread will provide you information on the all the fuses and relays. Item # 15 will link you to wiring schematics.

Goldsmithy has a very good comment on the oil pressure.

Will not start, does that mean it turns over or nothing at all? Sounds as if you have a auto so yes check out any lock out switch including the immobilizer.

Opened up the ECU and looks like previous owner had been in the ECU and broke the ribbon to the pins. Going to send off ECU, Key fob, and EWS off to Oakland Park Florida for repairs. Has any one used these guys? http://www.ecudoctors.com/ .
