Introduction and need help please
 

Hi my names Kodie from auburn Washington.
I bought a 97 blazer first one ever owned that’s Starts up revs to 3000 rpm for about 3 seconds then Boggs down and dies after I’ve replaced the map sensor, maf sensor, tps sensor and about to replace the fuel filter.
i was wondering if anyone else has had this problem and id they have any advice that could help

thank you for your time

Welcome,
Fuel Pump?
do you have pressure from pump?

Other will chime in shortly with suggestions

Welcome to the Blazer Forum...

First, welcome to forum!

Second, go ahead and check your fuel pressure before you throw anymore money at it. There's some really good write ups on here on how to do it.

Are there any trouble codes present? Cel on?

I will look at the fuel pressure and it showed no codes which I thought was weird

There's no codes for low fuel pressure, per se, but I've often noticed a P0300 when my pumps were going out. Probably just from the misfire as a result of running super lean, since the pump couldn't keep up

Sounds like the MAF sensor is not plugged-in; check the connector for it.

OP said he replaced the maf, quite possible it's not plugged in all the way. Mine doesn't have a maf, so I'm not familiar with the symptoms
