Vehicle is a '00 Sport (built 08/99), 4.0 OHV + M5OD. It was running strong last weekend, then I disconnected the battery when I replaced a bad SRS sensor and wired in power seats. The battery was left unhooked for the week.
Today, I reconnected the battery to move the car but was met with a no crank / no start condition. I tried jump starting and it made no difference, so I took my battery to AutoZone to be checked. They said it scanned okay, but was only 43% charged and offered to charge it. Then once they charged it, they rescanned and it came back as bad. I bought a new battery, hooked it up and still had no crank / no start. New battery reads 12.4 V on my multimeter.
I started with the obvious things:
- Disconnected negative cable and cleaned connection at starter and ground on radiator support -- no change
- Checked fuses (including 175 A to power distribution box) and none were bad
- Replaced starter relay -- no change
- Inspected CKP, clutch pedal position sensor, and PCM connectors and found no signs of damage,
To clarify, all my interior lighting and dash indicators are still working but when I turn the key to start, I hear one click in the relay box under the dash and nothing else.
I started looking at starter troubleshooting in my Haynes manual, which references a starter relay with a push-on connector in the engine bay on the inside of the fender. I remember my '97 had this, but my '00 does not.
Can anyone offer some suggestions for what to try next in my troubleshooting? Thanks!
