VATS problem

Ok, heres whatcha do.
First jump the clutch safety switch (gear selector sw if automatic) and try a crank. Also, measure the volts on the jumper, you should have 12v in crank position or the start enable relay is not closed. If you have 12v and no crank, then you have starter problems. If no 12v, then remove the hush panel above the drivers feet and find the 2 wires from behind the steering column that go to a 2 pin connector. Unplug the connector and insert ign key. Measure the resistance across the 2 wires from the steering column. It should measure the same as the pellet and if over 13k ohms, you need a new ign tumbler which will have new contacts that make with the pellet. You can temporarily bypass VATS by connecting a resistor the same value as your pellet across the 2 wires that go into the wiring harness (goes to VATS module). You can use a 1/4 w or larger power resistor from Radio Shack. Don't permanently bypass VATS because 99% of thefts are done by bashing the column and jumping the ignition.
