My car shut down while driving on the freeway, won't start, two days before when i came to a stop and started to go again it would bog down like it was out of gas, it wouldn't do this at every stop, is this my fuel pump?

If you have an overdrive transmission the direct drive clutch may not be releasing. Have the trouble codes read to see if the computer or a sensor is starting to fail.

tune up time
or just clogged fuel filter. same deal,

check the battery~~~ and starter, and ignition~

if it shuts off while driving and will not start back up for at least 10 minutes, then it may be the crank sensor doing this. is check engine light on! if so get it scanned to find problem code. if no scanner, auto-zone will scan for free. if light is on. CPS symtoms are: car dies and won't re-start till it cools down, or won't start at all. good-day ! crank sensor timing will be out of sync. it controls timing and sends info to pcm.

You need to chekd fuel pressure sound like the fuel pump or the fuel regulaqtor is going bad.

Altenator went out on you. Once the battery was drained that is when everything shut down on you.

Take the Vehicle to a Automotive parts store and they will scan the on board computer, ( for Free ) and retreave any strored Diagnostic Trouble Codes.Then bring the list of Codes back to me and I will Assist you with whatever the problem is. And about the key deal try replacing the starter relay.

What are the fault codes you read.

My 2002 Millenia just started doing this the other day, while on the freeway when it started doing it i would shut engine off and restart it and it would be good for a while then it would do it again, i am still looking for solution, has any one found one?

Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
