Customer Question
My 1998 chevy tahoe...

My 1998 chevy tahoe will start and run but shuts off after a few minutes, had to replace the steering column because the shifter handle broke off at the column. has good fuel delivery,

Mechanic's Assistant: Has the vehicle turned into a gas hog? And how does it start -- same as usual?

Before changing the steering column, it was doing ok on fuel milage, and it still starts great now

Mechanic's Assistant: Are you fixing your Tahoe yourself? What have you tried so far?

Have a private mechanic, he has changed ignition switch[my old one from old column]checked fuel flow, he says it may be losing spark

Have you checked for codes in the computer?

Are there any anti theft lights or security lights on or flashing on the cluster when you turn the key on or when trying to start the engine?

ok, please give me the information i need to contact you again
Chevy Mechanic: AMEDEE, CHEVY TECHNICIAN replied 10 months ago

We need to check for codes in the computer, we need to see if the engine has spark when cranking or when it stalls out and we need to see if the security light is on or flashing when this condition occurs.
