  1. 2006 Cobalt No Spark

    Problems and Service
    I have a 2006 cobalt with the 2.2 in it. The engine locked up so we got the 2.2 out of a 2007 hhr. Everything hooks up 100% except the 2007 version has vvt plugs. I'm not getting any spark and the engine ran fine in the hhr (hhr was totaled due to rear end). We've checked all fuses and relays...
