Hi fellas,
I have just installed a Core4 PNP ECU from DIY-EFI and it is giving me some issues when it comes to getting the car running.
All the hardware has been installed (TPS, Wideband Controller, MAP Vac Line) and the most recent firmware and base map loaded (202103 Firmware).
Initially, I had to jump the AFM connector and switch the fuel pump pin to A9 to get it to prime on the key, however it has suddenly stopped working, the pump no longer primes or runs. If I jump F/P and GRND in the diagnostic port, it works fine.
Also, it appears that the car has also lost spark as well as fuel pump, as it has gone from trying to start (coughing, farting, backfiring and sometimes running rough for around 5 seconds) to being dead in the water.
I am no expert when it comes to TunerStudio or Arduino/Speeduino, this is the first time I have attempted anything ECU related.
If anyone has any ideas or info on where to start/what to check, please let me know, as this has turned into a right head scratcher
