1995 trouble codes

I can't get my mil to flash codes light does not come on exept when the voltage to the sensors drops. the light is good

So MIL won't come on when you first turn the key on? Interesting. I'm gonna double check to make sure it does on my '94....just for a reference.

My engine light (MIL) does come on for about 2 seconds after start-up and then shuts off. If your MIL doesn't come on during this time, I'd say that either there is a ground problem, a power supply problem, or maybe the ECM is bad. A good way to check is to see if a code scanner will communicate with the ECM. Autozone or possibly Advance Auto Parts can connect a code scanner for you.

I have to check to see if my mil light comes on like yours, it does light up but I wasn't paying attention. I just got an Actron(?) scanner and sometimes it doesn't link up it only shows o/d and a/c codes. I was told if you have a bad pcm in some cases the scanner won't pick it up. I am going to get another pcm (any suggestions for a reasonably priced one?) and keep mine and fix it. I have all the equipment to do this. Thank you for your help..The pcm for these years only has one problem so if anyone has a problem with it don't change the cam and crank sensors, I can almost guarantee it is the 8v output to these sensors.(orange wire) so a pin can be stuck in the insulation and with a vod you can check the votage to ground. Mine pulls in the two relays at about 5.5v.

I don't recommend a used PCM, but I would try places like Autozone, Advance Auto Parts, NAPA, etc.
