Run fine when parked , tried to start it the next day, cranks over wont start . Check codes U1000, Cooling fan runs all the time , No check engine light in dash. Thinking bad grounds to computer ? Thanks Update found neg battery cable broke off at transmission , Fixed it , still wont start hoping it did not cook the ecm ! Got it to run new computer , replaced neg cable to trans , just sits there and idles and I have no power to ac compressor.. Couple of coil packs bubble out of the sides , going to replace them next ....
