Run the fault codes but I suspect that there is an injector problem

SOURCE: Ran out of gas and now she won't run!

i would say that you have a bad fuel pump or if you have a carb on it the float inside the carb is stuck check these and i'm sure you will find it's one of these.

I had the same problem, it ended up being a fuel level sensor, if you run the car at low fuel level numerous times it goes bad. I had it replaced and runs great.

SOURCE: 2004 Chevy Trailblazer idles rough.

If it has not pulled any codes (idiot light). Clean your throttle body, and change your spark plugs with A/C Delcos #41-103, most other brands will cause rough idle like Autolites and Bosch. This would be a cheap way to fix this problem.

If by chance you have just recently changed the battery or had the battery unhooked. Let me know, it's an easier fix that costs virtually nothing.

IF there are no CEL's, remove fuses #10 and #28. Remove your throttle body and clean it with sensor safe spray like Seafoam. Can reuse the plastic O-ring. After clean, reinstall fuses and drive around for several miles so the computer can relearn.

Ran out of gas in 2003 trailblazer runs rough ever since and poor fuel milage


I show a fuel filter for the 8 cyl engine so I assume there is one for the 6 cyl too. Around 2004 or 2005 GM stopped using replaceable filters.
I would start with replacing the filter and running a few cans of injector cleaner thru the gas. You may have picked up some dirt from the bottom of the tank.

Ran out of gas now is running rough i replaced the fuel fillter but is still running rough


you will have to clean the fuel injectors and check fuel pressure, maybe the pump is going bad, dont let the fuel pump run without gas, some way gassoline works on the pump as cooling too, and if running dry then it will **** air and burn the pump,

I shut my car off at 430 in the morn ran fine but let the gas get real low tried to start it at 100 in the afternoon nothing then it started up after i put in gas but check e light has been on and idles...


if the gas got really low to the point of almost running out it could have sucked some dirt off of the bottom of the tank an clogged the fuel filter,or could have caused a cavitation in the pump do damage to it, I think I would start there if you have had the bad coil replaced.

It sounds like a few different things or a combination of more than one.

  1. The EGR valve
  2. The catalytic converter
  3. The mass airflow sensor
