The check engine light issue could be a faulty dash bulb or consul. It looks like you could do worse than get your car checked out on a diagnostic consul.

Failing that, emissions failure is usually a fault of the engine not running at optimum. Is the air filter clean, air temperature sensors clean. Finally take it out for a good run to burn of any residues before checking emissions.

bulb is probably blown... you have to remove the instrument cluster to change the bulb

SOURCE: car engine wont turn over

it sounds like either the key is going bad (chip inside) or the PAT's immobilizer system is not detecting a key is inserted with the correct code. If you remove the column surround you will see connectors just make sure all of these are secure, watch the yellow one do not disconnect it as its the airbag and theres a chance of it deploying.
Also try your spare ignition key if you have one.

If all is ok i'm afraid you may need to make a trip to ford for them to diagnose, the pat's system works well almost too well sometimes. i deal alot with them while installing remote starts and when they go wrong its almost always the dealer to resolve it. They have the computer software to test the system.
Sorry,

SOURCE: 1995 Jeep Wrangler 2.5L Fuel Pump/Check engine light

Could be one of several items...I'd check the fuel pump relay, auto shutdown relay and the ignition switch itself. I'd bet on it being one of those relays but, we all have been fooled at least once!!! I'd also make sure that body and engine grounding is good and clean. Relays can't work properly without a good ground.

Chekc engine light dont come on

The light comes on or does not come on? If it comes on you need the car scanned for codes to see where the problem is and why it will not pass test. If it does not come on check the blub.

My 1996 Nissan Altima has had the Oxygen sensors and EGR valve replaced. It needs to pass emmissions test but evan after driving it fo rover 500 miles the The ECM will not reset eventhoughtthe fault codes...

Putting miles on them wont reset the computer. It is how many times you cycle the key on and off. And they will only reset if the problem was fixed. I don't know how many times yours has to be cycled, but some vehicles are up to 100 times. Hope this helps.

98 honda accord wont start took starter to shop which passed the test. Need to know what other problem it could be...key turns all the way lights, radio all that comes on but wont start?

check your starter relay. if the starter passed the test at the shop check to see if you are getting signal to your solenoid on the starter it shoul be the little post when you turn the key to the crank position, check to see if you have power at the big post which comes from your battery, check your grounds. check your fuses see if you have a crank fuse or an ignition fuse.

93 yukon 350 wont stay running at idle

when you crank the engine do you see fuel spraying from injectors .if you dont check for power at injector connectors one side should power and the other will be ground controlled from pcm.you can test with a 12 volt test for both. first test with test light grounded for power then test with test lead clip to battery to pos to the other wire from pcm while cranking engine light should flash.if it does turn key off again lean over tbi and have somone turn key on and listen for fuel circulating through tbi unit if you hear it without cranking engine replace fuel pressure regulator.
