That code is for the battery temp sensor reading too high.

There chould be a battery cover over the battery with a vent tube. If all that is still in tact, you probably have a bad sensor.

Here's where it is.

Does the check engine light come on for bulb test when the key is turned on?

Do you have power to one side of the injecters with the key on?

I didn't ask you about the PCM. I asked if you have power at one of the wires at each of the injecters when the key is in the "on"" position.

OK, we're getting some where.

Your having a problem with the ASD (Auto Shutdown) relay circuit. That is what powers the injecters.

First check it's power supply which is fuse #21, it's a 20A fuse.

If that is OK, then your going to have to go to the relay and make sure the power is getting there and then, that the relay is energizing and sending power back out on the Dk Green and orange wire.

Here's the location of the relay
