I went to start my Venture after it sitting in the shed all summer and no go. The display lights up but the engine won't crank. I noticed that "code 11" was flashing on the screen. I read through a code 11 threads here for an Apex. I was wondering if there is anything else I should check besides the starter relay? I read another thread about a sensor at the spark plugs that needs to be checked but getting to the spark plugs means taking the gas tank out???
I would suspect contact corrosion somewhere. Any help appreciated.
