[Crazyrosco]

Hi everyone.... i have looked at many posts... and tried many methods..... but id thought id raise a question for some assistance....

i have a 206 gti... which i remapped and made the car unable to start due to low battery voltage (my neglegence )

anyway....

i have replaced the ECU & BSI & KEY FOB.. (MATCHING CAR) slavage donor car..


and replaced the Battery to sort this economy mode problem... also cleaned the EARTH battery connection...

but im struggling ...

1) what to check, electrical test

2) what to do next

ive tried goin back to BASICS..... i believe there is compression.... No immobiliser fault.... i believe they are paired matching ecus key etc....


i have 10.65v to the coil pack... and WET plugs after many times tryin to fire the car up...


just wondered if theres anything im missing? ... or a tip that might help from someone that has had same experience


..
thanks Rosco

Hello to all.

You can try to give direct +12v from battery to common end of petrol injectors, this way you will provide good voltage to injectors, coil, and front of engine electronics.
Or you will have to check BSM ( front fuse box ) for power problems.

If you have diagbox

1. go in engine ecu and check immo status ( locked , unlocked , matched )
2. go in BSI and check for errors
