hi, i have a 1997 chevy blazer 4wd and for some reason it wont crank up. im guessing is some type of sensor but i had replaced the fuel pump, fuel filter and still the same problem. can somebody help me with this problem?

 

Can you give us some more details?

When you turn the key to the start position, does the engine turn over? Or do you just hear a click? If it does turn over (starter turning the engine), but won't catch and run, then you have to verify fuel, air, and spark.

You can check for fuel pressure at the fuel rail behind the throttle body. To do this properly you should have a gauge (~$25 at the autoparts store).

Please give us some more details and we'll try to work through this with you.

 

my 95 blazer wont start,this morning it ran fine but when i tried this afternone there was no power what so ever to the engine.this i the 3rd time this happens to me after aabout a day or a few hours it will turn on like nothing ever happend?

 

My old car did the same thing, it turned out to be a relay... thats a Honda though. Is there no power electrically (your lights and stuff) or is there just no way it'll turn over... all the answers to swartlkk's questions are kinda helpful to know anything regarding the actual problem.

 

Sounds like your fuel pump is going bad. I replaced mine last summer due to the same symptoms. It's better to replace it now before it decides to cut out on you while you're driving in traffic. How many miles do you have on your vehicle?
