My suburban will start and run for 17 seconds and cut off. You must turn off key completely then re-start it. You may have to do this 4 to 7 times before it will stay running. Once you have run it and turn it off you will go through the same sequence to get it to run. I have replaced the computer and prom chip. Could it be the fuel pump or distributor?
