Has been starting right up no issues. My on board computer is losing her mind and that’s been for almost a year now. Any suggestions?

Hi,

Can you tell me what is happening? Does the vehicle no longer start at all? Is it a hard start now? What symptoms are you having that you feel are related to the computer?

If you have any diagnostic trouble codes from the computer, let me know what they are.

Take care,
Joe

It will crank but not start. The computer does not work no codes. No clock either.

Okay, is the DLC connecting to check for codes? I attached a pic below. Check for power to the pins that indicate 12v and continuity to ground on the pin indicating ground.

Let me know.

Also, let me know if you have checked fuses and if this is the procedure you used to check for codes.

Take care,

The fuses in the box under the hood are all good.

Does this vehicle have an OBD2 connector plug for scanning? 1995 was the first year this was introduced so some vehicles had it and others didn't yet.

Let me know.

If it does, it will either be under the dash on the driver's side or some have a door you open in the kick panel to access.

Let me know.
