Engine startup problem

[vladjan]

ok, last couple of days in the morning my car has been acting up in the morning. when i start it, the car turns on and then immideatly shutsoff. On the second try it turns on... stays on.. but makes a weird noise for about 20-30 second ... then everything goes away. it only does that in the morning ( so i guess when the engine is cold).
Ok recently about 4 k ago, i was sitting in the car after driving for a about 20 mins, then tried to start it up but it would do similiar stuff but never turned on completely until like the 30th try, then the engine check sign came up.. it had to do something with the throttle, so the dealership replaced a throttle.

im lost and have no idea what can be causing this... if i bring it in the dealership, i have NO codes or anything because the car runs perfectly ( only acts up in the morning). i have 98.5 k on Mazda 3i 2004. i still have extended warranty until 100k but that will run out by the end of next week : (

please advise what to do with this..
Thank You

p.s. i believe it could be the fuel injector or pump.. so it doesnt put in enough gas so it turns of. Note*: fuel pump has been replaced at about 60k.

ok .. the dealer told me that there are too causes because the fuel system is losing pressure..1) fuel pump, 2) debree in the fuel tank.
Than they told me that it costs 230 bucks to bring down the fuel tank and check whether it is debree or the fuel pump. if its the fuel pump, my extended warranty covers it if not, i would have to pay 230 bucks plus additional cost to take out that debre.
we'll c what happenes.

fuel pumps are a big problem with our cars... gladly i have an 2004.. ive replaced purge valve solenoid 2 times.... thats all i did..so far so good...

 

[vladjan]

i have already replaced the fuel pump once, motor mount twice, and solenoid valve once.... the problems keep piling up : (
i have 99k miles on my 04 mazda 3, warranty runs out in 1 k great, lets hope that my fuel pump went out so i can get that part new.
i think the 04 has so many problems because it was the year this model came out.... it happens to all cars the first year they come out.. oh well i still love this car

niceeee they replaced my fuel pump. 900 dollar service cost me only 50 dollar deductible : )

ok i seriously need help with my car... so the dealer replaced the fuel pump cause the car wasnt starting. i had 99k on my car. today in the morning the car didnt start again!!!!! and i have 100,020 miles already. out of warranty!!! maybe the fuel injector is the cause... i have no ideaaa. i will visit my mechanic tomorrow and make him find the problem and than once i find the problem i will go back to the dealership and make them fix everything with no charge because they havent fixed my concern from the start while i had warranty, now im out of it and i still have the same problem.
