Anyone want a blazer? Bout to sell this roaming headache
Wouldn't start after initial death, started once and made it a block down the road and died again and just crank no start

 

There is a good thread on diagnosing crank/no-starts.

 

Are you asking for diagnostic help?

I am going to guess that it is the fuel pump.

I have replaced my fuel pump twice, the first time the mechanic put in a no-name fuel pump against my wishes (I requested AC Delco/OEM GM) and it died in less than 10k miles (the original lasted more than 150k miles) and I wasn't fatiguing the replacement fuel pump with low fuel levels.

Napa auto told me that the Delphi fuel pump is the OEM fuel pump. I installed the Delphi fuel pump after the failure of the first replacement. So far it has been fine but it hasn't been that long.

 

If you want to go with the parts cannon, no problem I'll bow out. Let me know of I can help and your up for the process.

Fires fine with a shot of starting fluid but dies right away so I'm going down the fuel issue route
Yesterday I popped the line off the outlet side of the fuel filter and confirmed good pressure back there
Going to check the key on and leak down pressure at the schrader valve in a little bit to narrow down the possibilities even further. Will report my findings

 

Pressure at key-on was no more than 15 psi, so I'm most likely looking at a new pump huh

 

Always do the fuel filter along with the fuel pump, if you need a fuel pump. Don't get a crappy pump--if you do, you'll be putting in another one very soon. OEM GM fuel pump is discontinued and some flavor of impossible to get. Napa auto claims that Delphi made the original fuel pump, and you can get a Delphi fuel pump for this vehicle, hopefully it is good enough! You can find a lot of ink spilled about fuel pumps for this vehicle, it apparently is rather picky.

And don't run your tank below a quarter gallon!

 

Your first test at the fuel filter confirmed that the pump is fine as long as you met the criteria in the fuel pressure testing sticky. The fact that it doesn’t hold it at the Schrader says it’s in the Plenum. The regulator or the injectors.
