That is called an intermittent problem. these are the most difficult to diagnose. you have to look at several things before coming to a definte conclusion. does it do it when the engine is hot ? Or when it is cold ? Does it do it all the time or sometimes ? Changing one part at a time can eventually lead you to the right part. But parts cost money. the best way to find out is if you can have it code scanned at the time it does not start.Then go from there. I hope you can resolve your problem. But don't waste your money installing one part then another etc.

    you can try the fuel preassure regulator. it is a possibility. If it costs you 20 dollars, well good. Take it to Autozone where they do a free scanning when it does start. take notice of the scan code. maybe we can find whats wrong with it. also always reveal the sixe of the engine.

With key off unplug the mass air flow sensor and try to start the vehicle. If it starts and runs fine, try cleaning it with mass air sensor cleaner, and plugging it back in. If cleaning doesn't solve the problem it may need replaced.

I have a 2004 Cadilac CTS we bought a replacement chip key which the Chev Olds dealer could not program I took the new key to a Cadilac dealer they told me the key is defective now the Chev dealer has...

Okay, to program a key you will need two keys that are already programmed, insert one key ignition turned on and engine off, remove the key and within 10 sec insert the second key and turn ignition on with engine off, remove that key and within 10 sec insert the key to be programed. you will need to do a 30 min.relearn with only one key,you will turn ignition on with engine off and wait about 10 min until light goes out then remove the key and repeat this step when light goes out repeat step one more time then use key to start car, computer has learned all info. you will now turn off engine, insert programmed key turn key on engine off then remove the key and insert key to be programed within 10 sec.all done good day.

Buy a Haynes manual for the vehicle ( most auto stores carry them). With this manual you can do nearly any repair on the vehicle, they give you step by step directions.
