[ZVOLV]

Do you think your crank sensor is bad?

Peel back rubber insulation on crank sensor connector at firewall. Backprobe the center wire, red/yellow, pin 2 with one lead, send other lead to battery ground. Multimeter to AC Volts, NOT DC, and crank engine. You should get approximately 0.4V AC cranking.

-Backprobe between Red/Yellow center wire and Blue/Yellow (pin 3). Check resistance. Spec should be around 200ohms (further data needed. Can vary), but if you see an open circuit here, sensor is bad.
