2002 Tahoe rough start and dies
My issue started a few weeks ago with it hard starting and quickly dying unless I started it a few times and rev the engine up. Then after I get it running and keep reving it may stay running or may die out again but seems to stay running if I put it into gear drivefor a minute and put it in park.
Then driving it for a while and Park Shut the car off, come back 20 minutes later sometimes it will start right up and go or start it a few times put it into gear answer it will sputter along and die. Restart it and it’s fine. Also when i am reving it up to keep it running it sounds like a loud knocking and clinking coming from my intake. The car has died while driving 3 times. First time took 20 minutes to start back up second time started right up and third time, well let’s just say I haven’t been able to drive it since.
so now the car won’t run at all now. Sometimes if with turn in and sputter around 400 Rpms and die or it will just try to start with no success. I know this sounds like a fuel pump issue but I can hear it working when I turn the key to the on position. And I am getting P0171 and P0174 on scan tool.
Thingsbthat I have done to the car since this started happening
spark plugs
02 sensors
clean and tested injectors
cleaned throttle body
cleaned maf
changed out throttle position sensor
What my future plans are to do unless someone has cause of issue....
fuel pump and filter
inyake manifold gasket
