why won't the motor crank over when the ignition key is turned

battery tested and charged at WalMart, it won't jump start, clicking sounds like it is at the starter. Dealership says it's one of three "modules"???

i only see 2 different ones.that's because if it's a 3.0L or a 3.9L.but you didn't say in your question.you only said 6 cylinder,they both are 6 cylinders.call local trusted repair shop for quotes,see what they say,compare prices.

you say 2 different modules. 1 for the 3.0 and 1 for the 3.9? what are these "modules" and what do they have to do with cranking the engine?

i read your post wrong!i thought models,you say modules!sorry

ok.start a new question,include all vehicle info.
