Right so i made a school boy error while jumping my car and crossed the terminals by accident, started my van there were no sparks or that. Left it 2 minutes and went to start my car and nothing happened, jamp out and realised what id done turned the van off and swapped the leads the correct way, tried again and all i can get to work is the lights.. Can someone shed a bit of hope and tell me ive not fried the ecu and hopefully just blown a fuse or just knackered one of the playes in the battery! Cheers
