[@MotordyneG35]

I need your guy's help. This is going to be a 3 part series. I've replaced the IPDM thinking that is what was blowing the ECU fuse, that was a $700 mistake because that wasn't it. I checked everywhere for a short and came to the conclusion my ECU itself went bad because when it blew the ECU fuse the 2nd time, I smelled burnt electronics. After blowing the fuse the 2nd time, the red security light is solid, the fans stay on and now the car will not start. I figured it was my ECU that actually went bad, so I pulled it out and sent it to my tuner to bench test it. He was able to communicate with my ECU so my ECU is good, but the burnt electronic smell was in the glove box area. I'm running out of idea's on how to fix this and no shop wants to touch it, being it's an electrical issue. Has anyone else experienced this problem?

[@BoOmBaMan]

If this happened to me. I would try to figure out which pin wire on the ecu harness is connected to that ecu fuse. I don't have sources for the wiring diagrams. Hope this helps get to the bottom of it

[@MotordyneG35]

I looked at the FSM for EC. It's pin 121 a red wire with a white strip on it. I guess I need to get a multimeter and start testing continuity on each pin. I did talk to an electric shop last night here in Encinitas, California. He is booked till October fixing van lifers van's with electrical issues, sick 70's VW vans. But he told me if I smelled burned electronics, then go to where the smell is. I go but I didn't see any smoke, just smelled it. He goes you won't see smoke because it's in a sealed unit, just like my ECU. Some board the like the PCM or BCM went is my guess as he said if you smelled burned electronics stop searching wires and go to where the smell is the strongest.

When the ecu is not seen and you everything else works it is normal to have the fans turn on high and crank no start. Nice simple fix. New to the channel. And yes pretty much ppl are not willing to help. Everyone is too busy with their own lives. As if they were actually grinding. Ive had similar situations and nobody is willing to help. Lock up my engine and had to push my car upa driveway to a gas station by myself. Asked if I could leave it there for the night and they say they would have it towed in the morning! Had to push it into the street.

Glad to see you still have the car bro! I saw it up for sale on the Facebook market place a while back. I had this issue in my 05 g35 coupe.. except my problem was the ipdm , some of the connections had burn marks on them so I replaced the ipdm.. eventually the problem came back and I realized that I didn’t clean the connectors on the harness.. cleaned them up and now it’s been driving fine

[@MotordyneG35]

All of my fuses on my IPDM were black, like they had been burnt, even though the fuses were not broken wires. I also replaced the IPDM thinking that was my problem but I never cleaned the connectors. How did you you clean them? Duster?

[@franklowe2180]

The same thing happened to my 04 g35. The battery tray gets water in it like a bowl after it rains. The bottom of the ipdm isn't sealed properly and I had to change out the fuse that powered the ecu. Simple fix is, drill 2 holes on opposite ends of the batter tray corners to let the water drain out. My car was down for 2 weeks trying to figure that problem out. The fuse is at the very bottom of the ipdm right above the battery tray so it's common for water build up to splash up on to it after a heavy or prolonged rain.

I have one issue tho which whenver I listen to music, it makes this faint high pitch noise. But, when I mute it, it somehow disappears. Sometimes whenver I speed up, it becomes slightly louder. Do you happen to know what issue I’m experiencing? There are also times that I don’t hear it.

Tyler - you gotta do a video on the new Motordyne exhaust (I have it); but it doesn’t sound exactly like yours….slightly different. Then again, I now have a rebuilt VQ35DE RevUp engine with forged 11:1 c/p ratio pistons. But still, my Motordyne sounds higher pitched and smooth.

WTF right there….and drives it HARD. 😲 My RevUp engine progressively burned/smoked more oil ever since I got it at ~99,000miles on it when it finally let go at 225,000miles. Did Tyler have a rebuilt/recalled RevUp from Nissan or is this all original from factory of 2005?! 🤔🤔🤔🤔🤔

[@muneymap]

The idiotic world we live in.

[@stealthg35infiniti94]

What I would do first is inspect/clean all ECU rated connections with Deoxit 5. Then if it still blows the fuses then a schematic wiring diagram is needed. Use a circuit breaker type fuse adapter in place of the fuse. Try to disconnect as much as possible with power and grounds to the ecm. If it doesn't pop the circuit breaker, then there's something shorted in one of the associated circuits. The hard part is issolating the problem. Some cables can feed several sensors. Disconnect the sensors. Does it still pop the circuit breaker? No, one of the sensors is shorted. Connect one at time until problem appears. Replace sensor. Retest. Yes, disconnect Battery, perform resistance measurement between the High and ground. The shorted cable/connector should show low resistance

[@jix750]

Maybe some one could help, my 2003 g35 runs and drives but the acceleration is not good at all won't won't do a burn out and takes forever to get to 35 but after that it's good , does burn out in reverse though lol and it's a new trans mission so it's not that

[@BoOmBaMan]

Hmm. I know it's pretty hot lately. Sounds like you could have a harness issue. I wouldn't be surprised if wires got chaffed.. I would pull the harness from below the cowl and inspect the ecu to the ipdm harnesses that are near the fuse box. Chances are the smell could be from inside the firewall above the ecu. Just take a look at your harness

[@MotordyneG35]

It ended up being a bad coil pack. After all the wire fishing and diagramming reading. An FN coil pack was the issue.

[@BoOmBaMan]

@@MotordyneG35 aww man. With all those symptoms with the smell and communication to the ecu is caused by one coil pack? And caused a blown fuse? I don't get it. That's very unusual 🤔

I have seen Nissan cars throw AfR codes when the problem was bad coils.

[@MotordyneG35]

and that ended up being the issue, I couldn't believe it. Usually you get a P0300 code for misfire but these are aftermarket coilpacks. They did this before but randomly dying with no code at all at 3 years old. Since they have a lifetime warranty, I just replaced them all for free. 4 years later the same scenario but a blown ecru fuse and no codes. Cylinder 2 the coilpack was melted so bad.

[@milsgarage]

Your G dedded??

[@kingbey8405]

High thought 🙄 what if having the battery disconnected so long, reset the nat's tune/settings of some sort..then when you drove it back, some how the tune was right, but confusion of the ecu triggered that response....I mean, coil packs dont go bad in storage...imo🤷🏾‍♂️ I would think it had something to do with tuning/ nat's delete...but again I'm red eyed, lmao! Keep'em coming!!!

[@MotordyneG35]

The tune has nothing to do with it. Letting it sit overtime has no effect, on resetting the tune. Most people say a rat nibbled on a wire for letting it sit so long, but after tracing the pin 121 the power supply to the ECU. I can not find a short in the red and white wire anywhere. Pulled out my double din LCD screen searching everywhere. Even checking the power supply to my radar detector if it came disconnected and shorted the power supply to the ECU. I'm going to try replacing unplugging all my coil packs and see if I can communicate with my ECU. After reviewing my older videos those import direct coils did only last 3 years and last time I had issues with the car randomly dying with no codes. Replaced the coilpacks and now 4 years later, this is where I am. Instead of randomly dying, I am hoping they are the reason for the blown ECU fuse. A couple of commenters said this also happened to them and after some google searches, it has happened to other platforms. Bad coil pack blowing ECU fuse. If its that after all of this, I will won't believe it.
