All started when the tensioner for timting chain broke. Fixed that problem, 5 bent valves, fixed, new crank, cam, oil pressure, sensors. running like a top and then all of the sudden ecm/ ign fuse blows as soon as I try to start. And battery light stays on but battery has been tested and is good, 12.5-13.5 volts.Try to find as many chaffed wires I could, thought I had it fixed, because fuse didn't blow , but now I have no spark.

try resetting your security system or use another key if another key doesn't work you'll have to h ave it scanned for a security issure. A new key will not work until car is started then you can program it as stated in your manual
