Re: z28 will start then stop

Provide more details; was it running fine up until now and all of a sudden starting doing this? Have you changed anything lately (pulled the intake off). Has the car been maintained;tune-up in the last 30K miles or so? All of this would help us help you. Try unplugging the MAF sensor and see if it will start.

Re: z28 will start then stop

I had a similar problem with another vehicle and it turned out to be the ignition switch. Do your gauges light up when you turn the key to the ON position? The electrical portion of the ignition switch might be worn out so that when the key is in the ON position your ignition is not getting the power it needs, but when the key is in the START position the contacts are still good and the ignition works for a second until the key is turned back.

Re: z28 will start then stop

Good luck on the Chevy ignition switch, I have no clue how it goes together.

You should try to make sure this is the problem before ripping the steering column apart. Turn your ignition to the ON position where your gauges light up, then somehow short circuit the starter solenoid to get the motor to turn over while the ignition is on.
