1998 Chevy Blazer has no power

I took it off and still no power with load.

The fuel pressure is 60psi with engine on. I will now check it with engine off and key on. I took the cat/conv off and checked it. I also ran the m/v w/out the convertor on and the m/v runs the same. It idles normal and no power when giving it a load.

I found that the fuel pressure is 52-54 with key on and engine off. I also hooked up my obd2 scanner and the scanner tells me it has to be connected to the m/v ( obviously it is connected) I then connected the scanner to another m/v and the scanner is reading fine but not when I hook it up to the 98 blazer.

The blazer is not idling anymore. I start it and it dies out.
Do you think fuel injector problems or sensors? I'm not a mechanic so my knowledge is limited.

Ok J+N,
I puuled the Spark plugs out and they are burnt to a crisp. I put in new plugs and tried to start it. It would not stay running. I pulled one plug out and it was black and smelled of fuel after only cranking the engine 3 times. I then cleaned that plug and returned it and pulled the fuel pump relay. The m/v started and ran rough for 10 sec then died obviously b/c of no fuel. Do u still think its a sensor or a fuel injector spider problem. If its a sensor what kind would it be. I'm sorry to sound like an idiot but i'm trying to fix this m/v. Thx a bunch

Do you think it could be the fuel regulator. Again I get 62 psi when the enginge was running ( now its not) and 56 psi with engine off key on.

The cannister that is attached to the engine pipe was clogged. I never thought to check that as I checked the cat/conv. Thx for the help though.
