Need help Malibu will not start

Hi guys I'm new here, I have 2002 V6 Malibu that will not start. I went to the chevy dealer they replace the fuel pump and charge me $535.00 to install it, But still will not start man. They are saying the fuel pump is 1 of the problems that is not the case I check the old fuel it was pumping. They still charge for the new fuel pump install and now they saying a few other things like the ejectors are bad. Can you tell me what the problems maybe, I have fuel pressure going to the throttle body is there any fuses or relays "o" where is the PCM located.

Thanks

Re: Need help Malibu will not start

have you considered checking the starter itself? is there any clicking when you try to start it? notice anything weird with the car before it stopped running?

Fuel filter isn't gunked up? You have enough fuel pressure?

Have the Antitheft Passlock Sensor checked, my mom has a 2001 Malibu that had the same problem about a year ago.

This is the sensor that senses the electronic chip in the key to prevent theft. Among the things it does is shut down the fuel pump.

If you are lucky a different key will work.

my firebird has had a very similar problem many times with the vats. have you seen any security lights coming on at any point?

The motor turns overs. just can't getting to start man I'm not going back to the
dealer any more. How can the charge you for a fuel pump when the old 1 is working.

What is the theft key.

Is there any relays for the fuel injectors, where is the PCM located.

Re: Need help Malibu will not start

Fuses and relays are in the owners manual, http://content.gmownercenter.yahoo.c...ibu_owners.pdf. The PCM is located under the dash, driver's side, near the steering column. Guessing and throwing parts at the problem is usually more expensive than getting it fixed at a reputable shop (this particular dealership excluded). That is, unless you enjoy doing the work yourself.

Re: Need help Malibu will not start

Along with what Starship and others said, check for fuel pressure at the fuel rail, check for spark at the plug, and make sure your air filter isn't clogged. Those are the three main ingredients you need to start: fuel, spark, air. It's the same triangle of ingredients for any fire. Remove one leg and the fire goes out, or in your case, doesn't start.

Get the issue down to one leg, so to speak, and hopefully not two or all three. Then find out why that leg, or system, isn't working.
