#477 of 609 starting and stalling problems
Dec 15, 2009 (7:18 am)
I just bought a used 6 cyl 1997 chevy blazer. It seems after all night ,in the morning it wont start untill I try about 6 times. Once I get it started its not that big of a problem. She will start easier. Also when it is in gear ideling I have to feather the gas pedal to get it moving or it will stall ( I can start it right after that). I have no problem with acceleration and dont seem to have any power loss when I am driving or going up inclines. I can hear the pump go on. I dont know if this helps but I believe the fuel gage is not working properly either It wont go over a 1/4. The truck sat for about 7 mos because he couldnt get it started at all.

Don't worry about the fuel guage right now.Very few Blazers and Jimmys fuel guage works properly in that year model. You need to replace the fuel filter,do a
basic tune up and check the fuel pressure.In the air filter box when you replace the filter,you may even find that chipmunks or field mice have made a home there.
After all this see what you find. What did you do to get it started? Make sure the
fuel tank is full of fresh fuel. Did the previous owner change the fuel pump? There are mistakes that people make when they do this.Do this and see what happens.
Fuel pressure should be between 54 and 61psi.

Thanks for the advice. I will try that. When I went to but it it almost would even turn over then we hooked up jumper cables and ............... it started right up! He claimed he couldnt get it started for over 7 mos. I did purchase a new battery.
Thanks again I will let you know how I make out

Also you have to consider that you have bad gas in there, after 7 months, unless you've burned it all up already.
Other than that, you might check the fuel pressure regulator. If it's bad, it will cause hard starts when the car's been sitting. You can pull the vacuum line off the fuel pressure regulator and if there's any gas in there, it needs replacing.

You have to take the upper manifold off, so you might want a workshop manual if you're planning on a DIY. But there's a pressure test connection (looks like a tire valve) that you can hook a fuel pressure gauge to. With key ON and engine OFF, pressure should read 60-65 psi.

I do not want to jinx myself but after replacing the defective caliper, bleeding the heck out of the brakes. I had one instance of the abs light coming on and did not do the issue where the abs kicked in at a low speed. May of been a combo of the bad caliper and air in the lines. The code may of needed time to reset as well.
If you ruled out bad or dirty sensors and are driving your self nuts, a good bleeding, and checking calipers would be a good place to start.
I used a vacuum hand pump to bleed them. $30 well spent once everything was bleeder screw sealed properly with a little teflon tape.
Thank you Cardoc50 for the advice

There is something every Blazer/Jimmy owner should know.... Every year from
1995 up has changes made to the wiring, fuel system,brakes and a lot more. That
makes things hard to diagnose. Every year they change something. That my
friends is hard even for a mechanic to keep up with. So be patient if it takes me
a while to figure a problem out. I will do my best to help anyone.
#486 of 609 prob with all dash gauges except fuel not working
Dec 22, 2009 (3:55 pm)
I have a 96 blazer I was driving and made a left hand turn and heard a pop and dashboard gauges with the exception of fuel gauge quit working, I troubleshot fuses and dash fuse was bad replaced it and everything was cool took off and fuse popped again and now will take about 1 second to pop fuse. Blazer still runs and drives but kinda hard for me to judge speed and it is nice to know oil pressure and other info any ideas thanx explorer62
