#3576 of 3676 1999 Chevy Blazer
Nov 06, 2010 (11:55 am)
Up until a month ago, my Blazer of 3 years had run great with a little over 100,000 miles on it. I loved it and never had any trouble with it.
Recently it began not starting. If left alone long enough ( 8-9 hrs ), I could get it to eventually start. So from the recommendation of a mechanic, I had the fuel pump replaced ( twice ) on my Blazer. The first one, I was told was faulty from the factory because it did not solve the problem.
Now ( with the $350.00 fuel pump repair ) it is slow to start ( which is a new sympton ) but unlike before NOW it DOES eventually turn over ( with enough cranking) and then it runs fine.
It NEVER did any of this stuff before. The battery is only 9 months old. The battery terminals are clean. There is NO service engine soon light on. Although it will start, I am wondering how long it will be until it doesn't, again. I can't seem to find anyone who knows what is up with the damn thing.
Any sound, solid advice would be MUCH appreciated !

#3578 of 3676 Passing CA smog
Nov 21, 2010 (3:22 pm)
My daughter's 97 Blazer with 160K mi. had an SES light up on the dash. My mechanic checked it out and it was a problem with the torque converter. It won't lock up in fourth gear at 60 mph (or at all) causing the computer to throw a code. He cleared the code and I drove the truck for 51 miles (under 60 mph) and took it in for the test. It passed all the tail pipe tests with flying colors but it couldn't complete the computer self test. The smog guy asked if the car had been recently worked on or if the battery had been disconnected. He suggested I drive the thing for 100 miles before trying to pass. I put another 49 miles on the truck and took it back. Still didn't pass the self test. The smog guy is guessing the computer is bad. Has anyone else had this sort of problem? Do I need to put more miles on the truck before retesting? I just want to get this thing passed so that she can sell it. Help!

The buttons blinking indicate that the vehicle didn't go into 4WD. The most common issue with these is the vacuum hose used to work the actuator. It runs under the battery and eventually the fumes eat away the hose. Also could be the actuator itself, or the cable from the actuator to the shifter fork that is inside the axle housing.
If you lie under the front of the car while someone else presses the buttons, you may be able to track down the malfunction. You an see the actuator and cable. they should move as the vehicle is shifted into and out of 4WD.

I had the same problem with my 01. Look under the hood near the fire wall and almost direclty above the distributor cap. There is a sloelnoid switch there that has two air lines (one in and one out) and an electrical connector. I replaced this and it has worked fine ever since. Came in handy as we got over 64" of snow just after replacing it. It is a DEALER ONLY part and cost about $56.
I can't remember what it is called though. The air lines (on mine anyway) were a bit hard to get off but once they broke loose they came off easily. I did the same that thing "johns" mentioned and checked the actuator under the battery. There were no tears or damage. So I replaced the solenoid.
Hope this helps.
