I'm no expert, but have you checked all the fuses, connections, grounds, etc? It would probably help of you let us know what you've already done to correct the problem, just so you don't get a page full of things you've already tried. Also, before anyone jumps in here, a search would probably yield some helpful tips that I'm just too lazy to search for myself... do you think that makes me a hypocrite?

yeah i checked everything but i heard it could mean a short and i might need a new ecu?

I've found that the connector for the leading plugs gets weird sometimes.

Try jiggling it and see if they start sparking. I know on one guy's car we had to put some electrical tape around his to hold it tightly together.

Could have possibly fouled them.
