I have a check engine light on so went to the store and bought one of those gm code reader but when I put it in my ecm my check engine light doesn't flash so I can retrieve a code .

Hi, My Name is ***** ***** for posting your question to just answer. I am a independent contractor for just answer, and ASE Certified Master Auto Technician with 20 years experience. I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resolution.There will probably be some equipment needed for a proper diagnosis. If you are not comfortable with this or do not have any test equipment please let me know ASAP. I also try to give all of the information you may need expecting a positive rating. I am not compensated for my time until you leave a positive rating. Your rating should be based on the service you received.

With it being a 95 it would not have generic OBD2. If you cross the 2 pins on the top right it should flash the light.

Yeah I tried jumping it off the fans come on but the light doesn't flash it just stays lit
Expert:  Tool Hut replied 1 year ago.

Try starting it and see if it starts flashing. If not it would indicate a possible defective PCM

Customer: replied 1 year ago.
It does flash when I crank the car but it's a non stop constant flash
Expert:  Tool Hut replied 1 year ago.

OK. I suggest having the codes read with a professional scanner. You may have a defective PCM. I would like to verify prior to instructing you to replace it.

Customer: replied 1 year ago.
I will try that by letting a shop scan I because I don't have one myself . Is the Pcm located under the air filter ?
Expert:  Tool Hut replied 1 year ago.

I just thought of something. Have you checked for a blown fuse?

F/P Fuse #2 15 amp

PCM/IGN Fuse #5 10 amp

Fuel Inj Fuse #6 10 amp

Fuel Inj fuse #9 10 amp

Also check the ground at left front of engine

Customer: replied 1 year ago.
I haven't check any of those. Are those fuse in the inside or under the hood?
Expert:  Tool Hut replied 1 year ago.

The underhood fuse box

Expert:  Tool Hut replied 1 year ago.

I believe it is in the air cleaner housing.

Customer: replied 1 year ago.
The fuse box in the air cleaner box or the pcm is ?
Expert:  Tool Hut replied 1 year ago.

Underhood fuse box. PCM in air cleaner housing

Customer: replied 1 year ago.

sorry about the delay I have been sick but I ordered an ob1 scanner and the code that came up was this. code 36 high - res failure. what does this mean and how can I fix it? tnanks

Expert:  Tool Hut replied 1 year ago.

The code description is pretty straight forward. If only code 36 is set replace distributor.

If it set along with codes 41 and/or 42 replace PCM
