No signal from the computer to the clutch relay for the A/C When you run a auto temp control test it will work , but it will not come on with the switch.

No, We was looking for anything on this van. We had changed a lot of things before we started talking to you. I just want to say thanks ,because it looks like the pcm was the problem!

Thanks!

I would just like to thank both of you for helping us out with this Van. We just put a used pcm in it and I think we have got it. It started right up and it is reading 3% and before it was reading 85% . We are going to let it sit for alittle and then try to start it again. So, thanks Ric ! I will be...

If the pcm is failing , why does the van run ok after it warms up? We just tried a fuel pump , because someone told us that there is a sensor on the fuel pump or on the fuel line that tells it how much fuel to put threw the system.

This Van is a pain!!!

Can anyone tell us what tells the computer that the van is running on ethanol ???

You can not tell anything on the computer with the fuel until it warms up and that is when it starts running better. When you first start the van it does not want to run.

We changed the #1 o2 sensor , someone cut the wires and it not have them hooked right on it.

Can you tell me were this sensor is ?

We replaced #1 o2 sensor already.
It did not make any change.

We put fuel in it and then drove it around for about 6 min.
Still is showing that it is on the wrong fuel.

Does anyone know any other way to get it to change back over?

The computer is showing that it is in E85 mode, but it has gas in it. The van is running very rich.

Can someone help us out on this one?

Thanks!
