cayte03, Perhaps try a boost of another vehicle to see if this allows the starter to engage. If boosting works the problem will be with the battery or the terminals on the battery loose or corroded. If boosting does not work problem could be loose/corroded/burnt/damage wires/connections, faulty starter.
