1999 Chevy Blazer 4wd
Car will start cold but after driving it around and shutting it off it wont start right back up, have to wait 30 mins to an hour. it will turn over but not start.

today after waiting i was able to start it but shortly after while driving it stalled out.

 

mine did this when my fuel pump started dying. check the test port and see if your getting enough fuel pressure.

 

that's what i was thinking, anyone know of a good replacement brand fuel pumps been reading online about people replacing it and there replacement goes out in 6 months....

 

did you get a service engine light when it happened to you with a code of p1351

 

P1351 Ignition Coil Control Circuit High Voltage

 

Update

I hooked a pressure gauge up to the fuel line and got 55 psi than i drove the blazer until it refused to restart, re-hooked up the pressure tester and got 28 psi. I'm still going to assume its the fuel pump and going to drop the tank and replace the fuel pump with a Delphi fuel pump that's on amazon for $200.

Will update more after i finish the install of new pump to see if that solves my problem.

 

Yep that's what mine did drive then weaken I'd also change the fuel filter too.

 

Update

changed out the fuel pump and fuel filter. car runs great now, drove it around and tried to get it to fail to start thankfully it started every time, also noticed it is no longer sluggish up hill and doesnt roar like it use to when id accelerate.

thanks for the help, now im off to figure out why the ABS light is on as well as the service 4wd light.....

 

My ABS light was on because my hub assembly was going bad. Couldn't tell you anything about the 4WD light. There is all kinds of post on here about that subject, only issue I've had with mine is the stupid actuator under the battery tray.

 

My blazer has 210000 miles on it, on the third transmission, (one which I had repaired, didn't know about the others until my tranny guy ran the numbers.) new intake gaskets last year, heater core. Just replaced my passagner side hub assembly last week. Got to adjust the T-bars soon and repair the power brake booster too. Yep just the normal blazer owner list of repairs.
