Question -
I have a 96 Eclipse 2.0 no-turbo  manual.This car stalls when driving or when idle and acelerate. If I try to start it again it dosn't have fire. I need to put the key to off position, take the key out, take the ignition fuse  out or disconect the batery. Any thing of this start the car again. Was having code P1390 but clean conection at computer and put dielectric grease on computer conections and check engine light went off. Oil light is on and sometimes is intermitent, on and off.

computer was change once problably twice.

Well, the check engine light didn't come on again I drove the car for 10 miles and start it 4 times. You would associate the stalling problem with the timing beltproblem?

 How the cam and crank sensor has to do with the coil pack?

Any idea?

Jose,
The code you were seeing (P1390) has a few descriptions.  What's strange is that for Eclipses, that code refers to a problem with an automatic transmission vehicle.  Having a manual transmission, that confuses me :-)  There is another interpretation of that code, which does refer to a loose connection at the car's computer.

But that code can also refer to a problem with communication between the crank and cam sensors.  That usually happens because your timing belt has skipped a tooth.  If your current timing belt has over 60,000 miles on it, replace it as soon as possible.

The oil light should only come on when there is not enough oil in your crank case.  This usually occurs when there is less than 2 quarts of oil in your engine.  Check your oil level, and make sure you have enough as indicated by your dip stick.  It may also be a good idea to change your oil and oil filter if it's been near 3000 miles since your last change.
Good luck!

Answer
Jose,
A stalling or hesitation problem can be caused to your timing being off.  Your car's computer (ECU) controls when your spark is to fire based mainly on the positions of your camshafts and crankshaft.  The ECU knows the position of your crankshaft and camshafts from the respective position sensors.  The ECU will not send a signal to the coil pack to fire the plug until the crank and cams are in the correct position.  And everything is kept in this "perfect" timing by your timing belt.  If you know anyone that has a timing light, you can confirm if your timing is set properly.  This site below will also give you excellent information on maintenance with your car:
