Ok... Weird non starting issue.

Fab doesn't unlock doors
Switches for locks windows don't work
Headlights don't turn on using headlight switch
Interior lights don't work when using switch
When turning ignition to on (not starting) headlights come on
Brake lights work
When attempting to start, it sounds like it should, but engine doesn't fire up
Charged the battery for 3 hours, same result

Will attempt to jump it tomorrow morning

 

Ok, couldn't wait, tried to jump, did not work.

 

did u remove the battery to charge it ? if u did your screwed u erased any codes that were in the system

 

No, the battery is still in the van and I have a code reader.... Will it work though if nothing seems to come on?

 

Also, even though the interior lights don't come on when using the switch near the headlight switch, if you click the individual light buttons, they turn on
Also, the fan works, but the on off button for the air does not work

 

I attempted to read the codes, but it said it couldn't connect the ECM

 

Sorry, ECU

 

Sounds like the CAN data bus is down. Do you get a tach indication when cranking. Any other instrument cluster problems. Security system light on? Check for spark and fuel while cranking.

 

Even in 2002, just about every function in a car was and is microprocessor-controlled. This is where to look, but where to start? As there are many 'body' functions not working right, examine the body module first for corrosion as previously outlined on this website. Of course disconnect the battery -ve first. Costs nothing and will harm nothing.
This may not be a DIY job, but one for an electronics expert -- usually the auto-electrician gets landed with a job like this. You may need a hard reset for every micro.
I hope no-one has been "messing" with it before yourself -- try and find out if you can. Without seeing the vehicle, it's well nigh impossible to come up with a diagnosis.
Sorry to sound gloomy about it, but being realistic.

Leedsman.

 

Raptor....can you clarify a bit?
What do you mean by tach indication? When cranking, nothing on the instrument panel was lighting up like normal.
