Hi, I've been reading the passed posts and found it very interesting, I've had my Blazer for over a year now, and want to tune it up. My little sissy truck ran fine up until I got the brite idea to drive from florida to virginia (some 1800 miles). Before I left I changed the oil, the battery, and the air filter. The plugs, rotor and cap had been replaced with in a the passed 6 month so i thought nothing of it. I left on a rainy morning, it rained most on the way up and back. I noticed about the South Caralina border and the Service engine soon light came on border the engine was running a little ruff, and the Catalytic converter sounded like it had hole in it, the brakes had no vaccum assist and were hard to push. the further north I went the worse it got it would stall at lights and idol fast and slow, but seemed fine on the highway. In virginia I changed the plugs cap rotor and PVC valve. No change, i raised the idol a little so it would run at stop lights. And headed back to Florida. Another damp trip, but the truck seemed to run better the further south I got. Any ideas of what may have caused this. It still seems tempermental but is running a little better. The truck is old with over 200,000 miles on it but up until now the only trouble i've had is a fuel pump and tires. Also i noticed alot of carbon (black powder around the mouth of the intake can this be cleaned out like a regular carb (spray gunk) and is there anything else I can changeout during a tune up? THanks

Okay, first off, not carb cleaner, but throttle body cleaner. Something different in the chemistry.
Second, check the vacuum line coming from the intake manifold over to the vacuum resevoir. Would be in the area around the brake booster.

my blazer wont start unless i spray carb cleaner in the carb.i've read that u need 60 psi to start but mine only has 50 to 55 key on engine off.it has a new fuel filter so dose that mean i just need to replace the pump? btw once i get it started it runs fine and useully will start again but not after sitting all night.plz help

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.

#286 of 497 97 Chevy blazer will not start

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!
