Car Wont Start =/

[aussietroy]

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

you can solder all wires without disconnecting the battery,

try removing the green wire and put the car back to stock wiring to see if it starts....

what happens when you turn the key to start?

it cranks but just doesnt fire =/

its not a fuel problem cause i can smell it and hear the pump

try putting the wiring back to the way it was and see if the problem is fixed

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.
