Newbie in need of help

The other day I went to the store, shut the car off which was running perfectly. I came out, tried to start the car and it was a no go. It would start but ran badly for about 2 to 3 seconds then stalled. It acted as if it were running on 2 cylinders. Come to find out after we got it in the garage, cylinders 1 and 4 are firing, 2 and 3 are not. Changed the coil and still the same thing. It is a 1993 Eclipse GS with a JDM engine 4g63. I have already checked plugs and plug wires. All are good. I can not find anything disconnected anywhere. Any idea's?

Thanks

Could be a few things, timing belt jumped, ECU problems are 2 big ones to check.

Timing is ok, checked that.
How do I check the ECU?

is the check engin lights on? flashing?

check compression!

check compression!
I have spark on #1 and 4....No spark on 2 and 3
Plugs are good, wires are good...one the side of the coil for plugs 2 and 3 is dead...
What i did was this, took all plugs out left them plugged in and cranked it, only 1 and 4 were sparking..to check plugs and wires i plugged 2 and 3 into the 1-4 side and they sparked.
Camsensor? possibly?

sounds like the ECU has aproblem.

your ignition coil could be bad... other than that your ECU but the CAS wouldnt only make 2 cylinders fire and no the others!

I changed the coil, same thing. Took the camsensor apart and noticed a very very tiny crack. Would that cause this malfunction?

it could... better replace it!

Some tell ,e it wouldnt matter cuz the if the sensor is firing 1and 4 it should still fire the other

I have no clue, this has everyone stumped. Anyplace else i can check to see if anyone knows?

i find it odd that their is no check engien light..

i find it odd too b/c i don't think 1g 4g63 n/t has CAS at all...
