Hello everyone.. I have a 1995 Chevy blazer 4w drive 5/95 ..

Can someone tell me where the fuses for the ECM or PCM are located? I have a scanner and was going to scan my blazer but it says there is no response from the Blazer .. So I'm thinking it could be a fuse. My check engine light does not come on even when I first put my keys in and turn to start all Lights in the dash come on but I see no check engine light .. What would cause this? Is it the Fuse...

 

I know some are under the hood in the box over the driver's fender well in my friends 97 jimmy so I'd start there, & plz don't double post just makes for a cluster **** & does mean you get an answer any faster. good luck on ur issue.

 

1995 was a transition year, 2 different fuel delivery systems and 3 different OBD systems were used, (one of the reasons Olds did not produce Bravada in 1995).

Which data link under the dash do you have?



Also, is the PCM mounted on the passenger side inner fender on top of the coolant reservoir?
Make sure you check all fuses.

 

Are the Fuses at the computer pcm or Where ? The Check engine light does not even come on when i turn my key ..would that cause that to happen?

 

Sorry didn't mean to double post..

If a fuse is blown, the check engine light and data link connector could both be inoperative. There may or may not be an underhood fuse panel on yours. If there is, it's on the driver side close to the radiator support, in plain sight. Check both terminals of each fuse in both fuse panels.

 

Mine Check engine light doesnt come on either

 

I have the same 95 Blazer with the OBDII data port but the OBDI data protocol. Like the OBDI where you can jump the A & B Terminal at count service engine light flashes to redeem codes, can you do this with the OBDII data port to get fault codes. If so, which terminals should I use.
