Unhook a wire from one of the fuel injectors & connect a light bulb to the wire. A #194 bulb works great for this. Just straighten the wires on the bulb & insert into the wiring harness for an injector. Bulb should pulse while the engine is turning over.

Code 58 (Pass-key fuel enable circuit)
Normally with a Vats problem the security light stays on & the starter won't operate. If the bulb doesn’t pulse (in above test) then I'm guessing you have a bad Vats module that is disabling the fuel injectors but allowing the starter to operate.

There is a difference between some fuel and proper rail fuel pressure. Check the pressure. You need at least 30 psi if not more.

You may want to do this. My son recently took his '99 GP in to have the fuel sender and pump replaced. (I guess he was afraid that Dad would blow himself up if I did it. ) They told him the pump was fine and just replaced the sender. He got about 15 miles away, stopped for gas, and it wouldn't start. He had plenty of spark, and fuel shot out to the front of the car when he tested for fuel at the test port. He could hear the pump prime each time he turned on the key, but the problem was a bad fuel pump. They replaced that, and it starts fine, now.

I tried that and the bulb does not pulse.

I also have another question. If the car is off should there be 12 volts of power going to the negative terminal of the battery?

With the key in run position check for 12 Volts at the pink/black wire going to the injectors.
What part of the car got wet from the sunroof?

I'm not sure how you're checking this but the battery has power whether the key is on or off. How'd you have the meter connected?

Theres 0 volts at the injectors.

The whole headliner was soaked and there was a puddle of water under the rear seat.

I read in a repair manual that if you connect a test light to the negative battery post and the disconnected cable, the test light should not come on. On my car it did come on. It says in the book that there must be a short somewhere. We tried to remove each fuse one at a time to see what is draining the battery but there was still 12 volts of power going through the car even if the alternator was unpluged.

Now we're getting somewhere. Check fuse #7. There are fuses on both the driver'* & passenger'* side. Check all the fuses.


Batteries going dead? What type of light bulb did you use for this test?

When you check for power at the pink/black injector wire you need to use the negative battery terminal so we know you have a good ground.
