It won't Satart (even after I change starter)

Hi, I bought this car ('97 Eclipse RS) 2 weeks ago I feel like I shouldn't bought it now because everything is going wrong but anyways here is my problem (I already search in other forums and only found similar problems)
the car start fine every time (as long is cold) but after I drive arround for a while (like if I stop at the store) and try to turn it back on sometimes it won't start it will do everything (power, pass gas and everything else but it wont start) and i remember i had a 1990 toyota celica and it had the exact same problem (the only difference was that the celica sometimes it didn't start even tho it was cold) and the problem with the celica was the starter (after i change it everything was just fine) but with the eclipse it didn't fix the problem I replaced the starter and still do the same. I was told it might be the computer and they told me to rest it i just don't know how. but it might not be that.
any ideas or suggestions (and does somebody know how to reset the computer? my car is the 2.0 engine basic model)
Thank you!

just take the ground off of your battery for like 15 min. then hook it back up.. that resets the computer....

Is your starter turning the engine over or is that starter not working at all? If the starter is not working at all then try these items:

TROUBLESHOOTING HINTS
The starter motor does not operate.
l Check fusible link No.4. <A/T>
l Check the starter (coil).
l Check for poor contact at the battery terminals and starter.
l Check transaxle range switch. <A/T>
l Check starter relay.
l Check clutch pedal position switch. <M/T>
l Check theft-alarm starter relay.
l Check key reminder switch.

My bet is loose battery terminals. I really don't see how resetting your computer would help fix a hard to start car. The ECU is either working or it's not.

the starter is already replace, so is brand new! and i do get power so is not the battery but thanks!

did you make sure its grounded... take a set of jumper cables and connect one end of the ground wire to the bolt that holds the starter in and connect the other end to the battery... if that works you need to run a ground strap to the firewall or battery! trust me.. i dont care if you think its good enough or not... try it! another thing is did you hook the wire back up that runs to the ignition? black with yellow stripe! needs to be hooked up for it to get power!

well the starter works just fine all the cables are hook and everything.
like i said the car starts just fine when is cold even sometimes when is hot is just sometimes when is hot it doesnt start. (i will say that when the car is hot it will not start 4 out of 10 times, but then after a few minutes it will start again).

but am going to try that next time it doesn start. thanks!

well it is very well grounded and still it doesnt work, so I finally give up on the car and took it to the mitsubichi dealer and they had it for 4 days and they say that nothing is wrong with the car and if it was doing something is not doing it anymore and that it might be the coil-pack but there not sure because everything work fine. any sugestions?

I would think starter as well, as if it had a bad spot on the starter solenoid. It starts fine cold everytime? If you crank it then turn it off many times in succesion does it not start? cold or warm? What do you do habitually when the car doesnt start? Keep turning the key off and on and then it starts? Manual or auto? Does the starter spin or is it just nothing? I ask because we had a similar problem come in on a ford ranger, put 2 starters in and it had a bad spot on the fly wheel.

I think we need some clarification here. Is the starter spinning the motor over? If so, changing the starter wouldnt have helped anything. Also, you sometimes have to buy 4-6 rebuilt starters before you get a good one. Thats just the way it is with rebuilds. Same for alternators. If the starter is not turning at all, use the steps listed above. If the starter is spinning but not turning the motor, I would look at the starter and flywheel. If the motor is turning over but not starting, well then, there are a thousand things that could be wrong. Please clarify, help us help you ;)

well just few days ago it didn't start even when the cars was cold. my car is standar. that same morning when it didn't start (in cold) i try to start the car by pushing it and it didnt start. i usually leave the car along and every now and then try to start it and it usually starts after a few trys. sometimes it takes longer but it starts. the starter does spin and it is turning the engine. the funny thing is that every time it doesnt start will first start for a split second and then it will die and everytime it does that is when i know it will take about 2-5 minutes before it starts fine again and in the mean time it will just not start. am beginig to hate mitsubishi I am glad I haven't sold my old 1990 toyota celica it still runs like a champ even tho I race the celica so many times and i have put so many miles in it (245 000 +) well if am missing something let me know i will try to be as clear as i can (english is my second lenguage)

ESL, that explains it :) No problem there, you answered my question. The motor is turning, just not starting. In that case the starter has nothing to do with it, and pop-starting it wont do anything. Could be cam angle sensor, fuel pump, etc. Dozens of things. Have to start to narrow them down. If you do a search there is a thread where I list several items to check. Eliminate those first at least, if none of them fix it. If I had more time I would find the thread for you...

l Check fusible link No.4. <A/T> OK

l Check the starter (coil). I dont know where the coil is???

l Check for poor contact at the battery terminals and starter.
l Check transaxle range switch. <A/T>
l Check starter relay.
l Check clutch pedal position switch. <M/T>
l Check theft-alarm starter relay.
l Check key reminder switch.
is well grounded (I already check) the switch in pedal is ok, I dont know what the transaxle range is, I have no alarme on the car and the key reminder switch is ok.

Note: after I took the car to the mitsubishi dealer they say that everything works just fine (and for my bad luck the car didnt give them a problem in the 4 days that they had the car) but the guy there told me he was 90% sure it was the coil pack but he didn't want to tell me that, that is the problem for sure!

should I sell the car after fix or you all think mitsubishi is a good brand and is just my bad luck!

did you make sure you had gas in it?

my brother did that once, his car broke down coming home from work one day and it sat for over a week before i looked at it..(had it towed to his place) when i finally got to it i looked at the gas guage and laughed.

LOL. Yeah it has gas
