T-Rev PLEASE HELP>>>ECU fixed but car wont shut off
I read on T-Rev previous post that he had to replace a diode to get his car to shut off after he replaced the burnt trace. I have a picture with some diodes labeled and if anyone knows which one needs to be replaced to get my car to shut off that would be amazing. Im hoping to finally get my Tomei ECU back in.THANKS!THis is not my ecu...

Hi Ross, sorry for the slow reply, Ive been racking my brain trying to think of something, and Im coming up blank. Ill tell you everything Ive found out so far.
On your picture A and D are not diodes, look like capasitors or something, but not important. The have continuity through them both ways anyways, so theyre not diodes. The only intersting one is "B" since it is connected to the ign circuit I would assume its the diode in question. And heres where things get screwy. I have 2 ecus, my half *** fixed 62 and an untouched spare 63. I checked both items "C" and "B" on both ecus, and both B and C had continuity both ways, which means they're not diodes.
I attached a pic of my fix on 62. I took it to work and had one of the electrical guys fix it, and he told me that B (if it was a diode) was hooped, also that he'd never seen a diode like that before and had no idea where to get one, but he sugested "Japan" I also smoked an E5 ecu (same issue) I fixed it the same way, and it was doing the not shut off thing so I threw it in the garbage. When I plugged in the 62, with the same fix, it amazingly enough shut off with the key off. I tested the B diode on both ecu's, it has continuity both ways. So I am completly confused. All I can say is the diode that runs the ign power must be somewhere else on the board.
The only people who do know what/where are these guys, [email protected] they told me $60 to replace the diode. I chose to buy the 63 ecu off ebay as a spare for about the same. For a tomei tuned ecu it might be worth it.

Just a heads up.
D looks like a resistor.
A looks like a capacitor.

Thanks man, Sorry for being a pain. And thanks again for all the info. Looks like ill be sending it out to get fixed. I will take a picture before so i can find out what they fixed so i can fix my other one and share the knowledge. once again, much appreciated.

I guess for the time being my fuel pump switch will have to do
Re: T-Rev PLEASE HELP>>>ECU fixed but car wont shut off (Naloos13)
no prob man, I wish I could be more help. Tomorow Ill take another look at my spare ecu and see if I can find anything insightfull.
You can still drive the car if you have to. You just have to stall it to shut it off, so drop the clutch in 4th gear or like you said, pull the fuel pump fuse.
