Sydney mechanic (4age knowledge) needed
Looking for someone reputable to fix some electrical problems for me! Can't figure it out myself!

What issues are ya having?
I crossed jump leads! From then on whenever the car got power the fuel pump kept running and the car just starts and dies immediately! I changed the ecu checked all fuses and it fixed the fuel pump problem but the car still starts and dies immediately!
efi relay is fucked
correct circuit open relay is priming the pump but not running it when its moved from cranking over to run
the dyno pull to 300rwkw
BT20v is making 300rwkw like i said i would without nitrous so now its time for some spray and see if she will run a 10s or less
My fuel open circuit relay is replaced by 4 relays as shown in the picture below! The fuel pump kicks in and is still running for a second after the car dies, is this def the problem?
check power to that circuit with it on reds (ign on, not start) from the little bit you have given us, my opinion is that, you have power when cranking, and lose it once it starts, which usually points to an efi relay fault, unfortunately, without the car infront of me I can not say for definite, but it is the first thing id look at, followed by power to the ecu, and then signals to efi relay.
remember in most cases, your ignition system, and fuel system are powered via the efi relay.
Ok thanks I'm guessing there must be power to the ecu because with my own ecu once the car gets power the fuel pump runs even with no ignition but with a different ecu the fuel pump turn on on cranking the engine? Could I just change these 4 relays and c if it helps?
yeah, be better off testing them to find the issue, simply swapping parts out may not help, check all your fuses while you at it, incl the big main fuses.
Ok thanks for your help
