You are in the Chevrolet Blazer Forum. Your Hosts are steve_ & tidester
We were driving for about 20 min and then it died so we pulled over tried to start it and it wouldnt start. it then started shaking and backfiring. We recently replaced the fuel pump and gas tank. Anybody have an idea as to why it's not starting?

Replying to: bedard (Feb 22, 2009 7:54 am) Several things could cause this, a MAP sensor being one of them. Generally speaking, the vehicle has suffered a hard failure and if it is sensor related you should have a code stored. Other concerns would be jumped timing from a worn timing chain/gear set. Also an ignition issue from the distributor.

Replying to: 92hatchbackk (Feb 24, 2009 8:37 am) My problem - the Turn Signal arm. There are a bunch of connections on the backside of the arm - if you don't pull it straight out when removing it the horn will honk, etc.... Seemed silly that they wouldn't insulate them more. So, I put some electric tape on the steering column and Dielectric Compound on the connections. Put the key in and it started fine. Turned it off and on a couple dozen times and worked every time. I haven't had the problem since. This was 4 months ago.

Hello everyone, I'm new to this world of online help. After years of working on cars and being out of the business I am finally stumped. I have a 1999 Chevy Blazer 4.3 Vortec with 189,172 miles on it and still running strong.....well when i can get it started. In the past as of three years ago replaced the fuel pump and filter. Both are fine and working. I have a fuel pressure at switch turn of 60 psi. and a running pressure of 54 psi. Both from what I understand as in with in range. Next I do have a good battery. Here's how the problem goes. When I go to start my truck it will try to turn over and sounds as it should, it just doesnt fire as it isnt getting fuel or the battery is weak. Now when you either a) give it a little shot of ether or you b) hook jumper cables it will fire right up. I'm kind of at my ends wit with this issue. Anyone have any good ideas as to where I can look to solve this issue. And please note this starting issue is only occuring when I start the vehicle for the first time of the day. Also when the weather is warmer out above 50 degrees it seems to start right up. Thanks for the help and input!
