Re: 98 4Runner replaced starter/ignition coils/wireset

If you don't crank, don't worry about the ignition system. Concentrate on the starting current.

First make sure your battery is charged and not drained.

Check the voltage drop across all the high-current connections and cables. In other words, turn the key to start and test voltage on the battery post and the cable connection, then check one end of the positive cable and the other. One end of the negative cable against the other end. The cable connection on the block vs the block, etc. All these differences should be very small. If you get a cable or connection with a large voltage drop, there is your bad connection or cable.
