Sounds more like a leaking fuel spider assembly. 55 psi is probably enough to get it going, and not likely to increase once started. If the fuel pump were bad, it wouldn't want to keep running.
 
You said this is a '97 model. You shouldn't be spraying carb cleaner into it as there are components that can be harmed. You might try taking the MAF out and cleaning it with an approved cleaner. The throttle body can be cleaned, but should be done with throttle body cleaner, not carb cleaner.

I agree with the other post either the spider or the fuelpressure regulator. Its not a hard job to do only took me 45 minutes, just make sure the bolts go back into the right location.

I have a 2002 blazer that will not start. It will turn over but not start up. I am getting a fuel pressure of 45, i do not know what it should be at. I am thinking my fuel pump is bad. I replaced one about 3 years ago. Anyone have a suggestion?

The problem is the fuel pressure regulator. the pressure should be 55-60. even 45 is too low. hope this helps.

About a year ago I noticed a problem with my 97 chevy blazer. The check gages light was coming on every now and then and sometimes it would cut off while I was at a light or stop sign. Then one day after I had driven the car all day, I came home and parked for about an hour. When I went to start the car it acted as if it wanted to start but did'nt. Six months prior to this I had gotten a new fuel pump, radiator, battery, and the spider and fuel valves changed. The fuel pump was from auto zone. The vechile has been sitting up for maybe a year and a half and I miss my truck. I did not have the money to get it fixed being that five to six months prior to the break down I had spent around $1,000.00 to get those things that I mentioned fixed. Can someone please help me try to figure out what is wrong? Any suggestions would help. I miss my truck!

I would try the crank positioning sensor.

Where is it located and about how much does it cost for the sensor?
