I am new to this forum and I hope somone can give me some advice. I am at my wits end with this 1990 3 liter. I fix one problem on the TC and another appears. This time the car is not having power to the gauges when I turn the ignition to the on position. The electrical accessories work, the windows, the lights etc. are fine; the starter will not activate nor strangely enough will the radio. This has happened on and off for the past several weeks. The car will at times start and run fine and then will do again what I have described above. There have been a few times when I was driving and the car would suddenly lose all power. After I stopped the car I was able to restart it again as if nothing had happened. This time I parked it in my garage a few days ago and when I went to start it today I had again the same non start issues as previously described.

Does anyone have an idea of what this could be?

 

Shoot it...with a huge gun.

Go find a manual and start checking your grounds.

 

Ok, thanks

 

My thanks to TNtech. You were absolutely right, it was a bad ground wire off of the negative battery post. There are many times in the past where I wanted to "shoot" the TC, but then when I drive it on the open road i remember why I bought the thing to begin with.

 

Cool. I like the 3.0L ones better. Those 4 cylinders are a PITA to find stuff for.
