2001 grand am v6 intermittent service engine soon light now car wont completely turn over and start

P0440 indicates the failure of the EVAP system to develop proper vacuum. If you got
and replaced a proper good quality gas cap, you have corrected the most common cause.
However, in fully searching the causes of this code (http://engine-codes.com/p0440_chevrolet.html ) (pardon the generic GM info, but will apply for you)-----you will find there are 5 other causes of the vacuum failure, which are independent of the gas cap. Your good local mechanic can sort those out; I would save your gas cap
receipt if you were advised to buy one not needed. As you probably know, your
State emission test facility checks your gas cap----so that is another way to find that specific portion of this answer,
(for their fee).
P0300 is a generic misfire code. For this, a specific Cadillac forum may be most
helpful = 2001 Deville intermittent service engine soon light code P0300
2001 Deville intermittent service engine soon light code... I recently bought this car from an owner who took decent care of it but a week after i bought it, the service engine light appeared. After a few View on www.cadillacforums... Preview by Yahoo You will see that this generic code is perhaps more serious, costly, and harder
to track down than the P0440. You will also discover that P0301 is cylinder 1 misfire, P0302 is cylinder 2, and etc, etc. If you get a good diagnostic, they will generally
be able to localize the problem fairly specifically---and get a more specific fix. The person who reported this code was unhappy because he was given several ($$) fixes,
before he got one that erased the code, and was a solution. (Be forewarned ----A generic misfire can have umpteen issues--or one! !; use your own local preferred method for solving this with a mechanic who gives you good service, and stands behind what they do.)
2001 Deville intermittent service engine soon light code P0300

There is a diagnostic procedure in the factory service repair manual for engine light lit ,no codes . Did you take it to ford dealer ? MIL - is referring to check engine , service engine soon etc...

• MIL always on when engine is running (no DTCs):
• MIL circuits

• For Focus, Mustang, Town Car, Continental, LS6/LS8, Escape, Windstar, F-150, Expedition and Navigator/Blackwood:
• Instrument Cluster, Section 413-01 of the Workshop Manual.
• All Others:
• GO to NB1

SERVICE ENGINE SOON indicator After the engine is started, the SERVICE ENGINE SOON indicator will prove out for a duration of three seconds. If the instrument cluster does not receive a message from the PCM within five seconds, the instrument cluster will illuminate the SERVICE ENGINE SOON indicator and log a diagnostic trouble code (DTC).

• An indicator is inoperative/always on - SERVICE ENGINE SOON

• Circuitry.
• Bulb.
• Instrument cluster.
• PCM.

• GO to Pinpoint Test P .

PINPOINT TEST P: AN INDICATOR IS INOPERATIVE/ALWAYS ON - SERVICE ENGINE SOON CONDITIONS DETAILS/RESULTS/ACTIONS P1 CARRY OUT THE INSTRUMENT CLUSTER SERVICE ENGINE SOON INDICATOR ACTIVE COMMAND Trigger the HEC active command MIL.

• Did the SERVICE ENGINE SOON indicator illuminate?

Yes REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual.

No INSTALL a new instrument cluster; REFER to Instrument Cluster . CLEAR the DTCs. REPEAT the self-test.

Service Engine Soon came back on and the car is again stalling ????? Did you have it checked for DTC'S - diagnostic trouble code's ? Service engine soon light on , codes will be present !

This time tell technician to use a dealer part. Some cars are fickle.

you probaly have a small pin hole in the evap system somewhere. Mechanics usually wont try to fix this problem because its a pain in rear end to locate the leak. This problem should not effect the performance of the car

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

I would take it back to the shop. It sounds like a short of some kind.

Do your high beam headlights work? If you have a burnt high beam light the daytime running lights won't work and then the service vehicle soon light comes on.

Sorry tina , but you are going to need a new "cluster assembly" most likely.The cluster assembly is the dash instrument panel with all the gauges behind the clear lens. As an ex-pontiac technician of 13 years , pretty much every one of these with more than one light remaining on after start-up is going to need an "exchange" cluster. What the G.M. dealer does is removes the cluster from the car and "swaps" it with another one that has been refurbished-not always do they have a local authorized repair source though. I know the going exchange rate on these units is about $250.00. Hopefully they don't mark it up too much from there. I recommend you have it professionally checked out and diagnosed as you could also have an ABS code which could illuminate the trac off , abs light and check engine light simultaneously. Good luck..............Scott

hi,

had a 97 grand prix and could not get the light out for any period of time, It ended up being the exhaust gas sensor saying incomplete burn due to an intermittent miss, had to change plugs, plug wires and finally injector service but the light stayed out after that, that was a 3.8 V6, hopefully that helps
