This is my first post, and I've been looking on the forum for solution's to my problem, but couldn't find anything. I apologize if my questions has been asked before.

I read that on the 97 blazers the ignition switch goes bad, and that why the blazer won't start. I replaced the ignition switch about 2 weeks ago. The truck ran fine for about 2days. Then it started doing the same thing. It just won't start. Also before installing the ignition switch I thought it was the fuel pump so to my surprise it wasn't. So now I'm out of ideas and don't know what else to do

Any suggestions or comments I would really appreciate it

Thanks in Advance

have you had the alternator tested?

 

when it doesn't start...are you lacking fuel or spark? jerry

 

It's lacking fuel. Sometimes you here the fuel pump turn on and sometimes you don't. I'm think that's why its not starting because it's not getting fuel. I also put a new fuel pump relay hoping it would solve my problem, but no still wont start.

 

you should put a fuel pressure gauge on it to see exactly what the pressure is. I assume it's ok when it starts but it's when it doesn't-those numbers we need to possibly direct you. How old is the pump and do you remember what brand it is? Pretty important. Jerry

 

Hey jesus22 make sure you follow up if and when you find the problem and I'll do the same. I posted here 2 days ago w/ same issue only I haven't started replacing any parts yet.

 

I checked the fuel pressure it has 62 lbs at start and 54 lbs when I actually get it to run. That's when it was I had the truck running, but now at start it gives me below 60 lbs. The fuel pump is not that old. I got it new at Auto Zone about maybe 3 or 4 weeks ago. As for the brand I don't remember what it is.

And now the only way it will start is when i pour gas down the intake and it starts right up, but will only run as long as the gas I pour in lasts then stalls.



Thanks for all the help so far guys. I really appreciate it. Hopefully I can get my truck up and running soon. Sucks walking to work lol.

 

I got my blazer running again. It was the fuel pump relay in the glovebox. I had replaced that relay, but I guess it was a bad reley I bought. But the good thing is I got my truck up and running no more walking for me
