1999 eclipse manual trans.2.0 engine non-turbo kills when stopping

so , it seems the engine does start in gear, with clutch depressed.
or cranks , brakes off, and car does not move. with clutch depressed, if yes, then the clutch is not 100% seized.
we now know the trans is in neutral (could be siezed check its Gear lub levels?)

I can not decode, stuck in gear. elaborate that.
nor "
"still stuck"
the only clue here, is
"stalls when clutch is let out."

this last statement makes me presume you depressed the clutch
then turn the key to start, it started
and when you let the clutch out, the engine stalls
does it do that rear wheels (2wd mode) ? lift driving wheels off the ground.... (these proves engine not weak)
yes, transmission is sized.
no, then it is stuck in gear.

2 things; If you jack up one front wheel, stick it in gear, does it try and turn the engine? If it does then the trans is turning. Did you check the trans operated in all gears before you fitted it?

Next, is it possible the clutch friction plate is in backwards. If so then the raised side that holds the damper springs is hard up against the fly wheel and causing the drag that prevents the clutch from releasing.
I cant help with info as to whether the trans is a fit but while you are underneath the hood, look and see if the clutch arm appears to move the right amount when the pedal is pressed. The only other thing I can think of is that the trans is seized somehow. You can test this while its jacked up by starting up on idle with it in gear, the raised wheel will turn.. Try this in all gears but BE CAREFUL with it on jacks, better to have jackstands under both sides.

i have fitted a new thermostat heat working fine. but temperature gauge not working

i would go with your line of thought to be honest

Since you didn't specify if you had the turbo or non-turbo engine, i'll give you links to both.
2.0L non-turbo (420a) RS/GS
2.0L turbo (4g63) GST/GSX

Did you check the fuel pump or fuel pump fuse?

BATTERY WONT HOLD CHARGE COULD BE BLOWN ALTERNATOR FUSE OR FUSE LINK.DAMAGE OR BROKEN ALTERNATOR WIRES.BAD BATTERY CABLES IF BATTERY CABLES BEEN ON CAR FOR A LONG TIME REPLACE THEM.BESURE TO TURN OFF RADIO BEFORE REMOVING BATTERY CABLES SO YOU WONT LOSE PLAYING CODE. WHEN YOU DEPRESS CLUTCH AND YOU GET A SQUEAKY NOISE.YOU COULD HAVE WORN DEFECTIVE OR BROKEN RELEASE BEARING OR WORN BROKEN PRESSURE PLATE SPRINGS.

sound like something killing your engine when was the last time that you change your fuel filter might be causing it..

don't get the "Cardone ECC model 793013" . i just check it out and when you click on the " See all vehicles this product fits " link, it shows this:

the problem with it is that the '97 PCM will not work on a '98. the pinouts on them are slightly different. The only 2 years that are interchangable are the 98 and 99 year models.
The part number for the correct one is 5293190AC.


If you get a remanned PCM that needs progamming, anyone or any shop with the correct programming tool can do it.

• PCM (ECU) REPROGRAMMING

1995~1999 Mitsubishi Eclipse RS & GS with 2.0L non-turbo engine (Chrysler 420A engine) ECUs have been equipped with reprogrammable processors since 1995.
To reprogram Mitsubishi vehicles, you must use one of two different reprogramming tools. For the 1995~1999 Mitsubishi Eclipse RS & GS (with Chrysler 420A engine), you must use a Chrysler Flash Reprogramming Unit, MIT992000-A . Click here to order one from SPX, or call them at 1-800-533-5338.
----------------------------------

I would suggest just buying a used (98 or 99)PCM. Then all you have to do is unplug the old one, take out 3 bolts to remove the bracket/PCM, pull it out, 3more bolts to remove the ecu from the bracket and bolt the new one in place. Its about a 5 min. job.
