hey guys

so about a week ago i made a bad mistake, while intalling a new tacho i cut the tacho sensor wire (yellow with red stripe in ecu pin 7 from memory)

its the right wire, i cut it and resoldered them adding the green wire off the tacho.

i f**ked up and forgot to disconnect the battery and now the car wont start.

no fuses have blown

ive changed the relay on my alarm over thinking it might of been the alarm but still nothing

then i took my battery in to battery world to check if i might of blown up one of the cells or something but still no go

i then put the ecu in dianostic mode and its showing error code 21 whick is ignition circuit

I have not a clue what to do now ... any ideas ?? i miss my 32 :(

Problem solved

turns out it was one of the relays next to the ecu (green/blue colour)

i noticed that i didnt hear them clicking like they normally do so i disconnected them, switched over and reconnected and she fired :)

i think im best off replacing them asap as on the first two drives the car died acouple of times (stalled) but its an auto.

    • Ok, can confirm.  if you use it like a normal human being in the real world, it works fine.  it only starts crossing wires if I keep using the fob over and over again in a very short period. So if I just chill the f**k out, it works 😂😂  
    • Im about to run a e30 mix of e85 and 98ron but i read that australian fuels specifically 98ron doesnt contain ethanol so on the calculator when it says pump ethanol percentage do i just put 0 or is this statement even true? And if it is true i assume i dont need to test any 98ron pumps.
    • So... the fob I had for my Skyline always had this issue where the "Unlock" button worked with no issues but the "Lock" button did nothing (and I always had to lock with the key) I thought I'd try resetting and pairing the key to the car today to see if that fixes the issue. I did the standard steps to program a key but realised my central locking was doing its own thing from time to time. 1st time: The driver-side doors would not lock or unlock when using the fob. No issues with the key. I figured it was the right time to change the battery in the fob so decided to go get one. When I went to the shop all doors locked and unlocked with the fob (while it had the old battery 🙃)   2nd time: When I locked the car, it would lock itself and immediately unlock. If I unlocked it, it would unlock and immediately lock.   3rd time:  After a bit of cursing and praying, that weird bug stopped. But then the rear passenger door started being a pain. It wouldn't really follow what the fob was asking it to do. Sometimes even using the key would not do what I wanted. So I'd lock the car with the key and all doors would lock, but the rear passenger lock didn't do anything at all. And then after a few moments, it would work again.   Is there a fuse that I should be looking at? or, is this one of those things where the door card needs to come off and some unit needs to be replaced? It just seems to happen from time to time and if I give her some space and come back later, there are no issues  🤦‍♂️ Also, should I try to program the fob again to the car just to see if that solves it?
    • One would assume a turbo is somewhere in its future down the line given they slap turbos on pretty much everything that arrives   
    • I’m guess it’ll end up with a turbo
