Battery terminals (remove/ clean/ retighten) or immobilizer.

ertech

will do the battery thing
would the imobilizer cut all the power ?if so where is it?
Thanks

the negative is real tight but has a little corosion<green> on it. can this cause it even if real tight?
Thanks

Yes. This is typical and presents high resistance during start which results in the system shutting down to protect from undervoltage. Did you also notice that your dash clock spins right after the failure?

ertech

thanks all for your help
will clean them before the way back
