Suggestions Anyone? '02 4runner, 6 cylinder. Owner replaced timing belt/water pump kit. He's not a mechanic but says he followed every step and took his time. He's a smart guy, a chemist.
He was in no hurry and the car was down for some time.
Afterwards car would crank but not start. He grew disillusioned, it sat for a couple of years. He bought a new 4 runner and gave the '02 to me for free. I had it towed to my house, yesterday.
Things I suspect might mean something about what's wrong: No check engine light symbol shows up with key on. No tach movement when cranking. I haven't checked spark as I believe there will be no spark if the computer doesn't detect crank rotation (?)
Any suggestions on where to start? I have an '03 but have never had engine problems. All my experience has been on vintage muscle cars.
Any suggestions appreciated.
