Hi forum, so I need help in diagnosing the problem to my 1997 Mitsubishi Eclipse RS (2.0L, non-turbo 420a) not starting.

History:
About a month and a half ago I bought this car but it required a tune-up.
Here are the parts that were replaced (PRIOR to this no-start problem):
-NEW Spark Plugs
-NEW Battery
..and others as well, but they would have no affect on this problem I have having now.

Story:
Okay, so obviously one of the things that helps most of us diagnose the problem to anything is what was going on before the problem occurred.
I had my car sitting idle for the entire time since I bought it, with the exception that I had to drive it to my place after buying it and test driving it for about a mile around my block.
The reason for it being idle was simply because I had been fixing and tuning it up. Just about a week ago, when this problem occurred, I was about to take it out for another test drive.
When I started the car, the engine felt like it was giving up and that the pistons were moving at a slow 1-2 speed. I immediately turned of the car to prevent any damage to the engine.
Right after a few minutes, I tried to turn on the engine but it only cranked and didn't start. I disconnected/reconnected the battery but still only cranked. I realized that my gas tank was
on E, but the light never showed up. Regardless, the next day I filled it up with a quarter tank of gas but it still won't start and it continues to crank.

Diagnosing:
-Checked power that connects to the Ignition Coil: [Good]
-Checked Ignition Coil by using ohmmeter: [Good]
-Sparkplugs are emitting an ORANGE spark
-Battery is *currently* being charged.
-Engine cranks, but doesn't start. However, once in a great while it seems like it is just about to turn on.
-Have *not* checked anything that deals with the fuel. Although I have a feeling it is not a fuel problem because I smell gas when cranking the engine.

Things I should probably mention:
-My dad wanted to test the engine's cooling system by removing the thermostat to the radiator. As of now, it is not equipped on the car. I'm certain that the engine is not damaged because it stopped running about the same time we did this, therefore the engine never had a chance to heat up.
-I had been using the radio and testing the headlights, etc. from time to time with only a few brief intervals of starting my engine (which would resupply my battery charge). As mentioned before, I am currently charging my battery.

when battery is charged

can you test if injectors are getting current

I am thinking ECU .. it needs 11.5 volts to work

and does your car have an emobiliser

make sure you have 12 volts every time you crank
a flattened battery will in time be damaged .if it goes flat often eneough warranty isnt honoured

fuel pump and filter might be ok if you can smell petrol

thinking on the rest

thermostat not an issue



this may help a bit

is the timing ok .. belt may have slipped a tooth ?

can you do this on your 97 -eclipse using a test light and count the flashes ?
just about the pin connectors .for fault codes...... the rest of the video is not relevant to your problem

have you checked the fuel pressure? There could be very low fuel pressure in the system, or no fuel pressure at all. When cranking , does the engine sound like spaced surges or like a fast whine?

Thanks guys for your responses!
I will most likely try to upload a few videos so that it would be easier for us to identify the problem.
However, I will do all the suggestions and periodically report back on what has been done.
Time is not in my favor so I apologize if I were to take up to a week to respond.

thats ok we have the time.. see you in a week

this bit concerns me .on an eclipse engine

the engine felt like it was giving up and that the pistons were moving at a slow 1-2 speed


..is it ceasing/ oil pressure / sticking valves or lifters /bearing problem or loosing compression

Have you looked into the possibility that the spark plugs emitting orange spark is a problem due to the crank shaft or cam shaft position sensors?
Also, I can't seem to find where those sensors are located. I think I know their location but not quite sure.

Orange spark , possibly means weak spark. Is the check engine light on. Have you checked the fuel pressure or is fuel delivery ok? You can check compression , also you can check a few other things , are the ignition leads to the plugs seem like original? Is the ignition timing correct? Is the battery fully charged? Is the alternator charging? A weak battery may not rurn the engine over fast enough to give a powerful spark as it should . Also turning over to slow can possibly over fuel the engine.

Okay so I didn't have enough time to check all of the above but I found something new.
For one thing, my spark plugs are now all fine and giving a white spark (as it should).
That being said, the only thing to look at is the fuel. So I did a test with my car and sprayed gasoline (or starter fluid) into the manifold intake
and it started but after about 2 times of starting the car, it stopped starting and it just cranks again. I tried disconnecting and reconnecting the battery but nothing changed.
The weird thing I found out when I did manage to start the car was that when I connected the PCV valve to the manifold intake, it turned off the car.

***Problem Solved!***
I finally got my car to start! It was a surprisingly easy fix too! All it needed was a new PCV valve which cost a couple of bucks!
Thanks so much for everyone's support

I guess an open vacuum source at the intake plenum can sometimes cause this issue, its very new to me in seeing this happen

**** Chrysler engine management systems LoL ( which this model has) except for the GS-T and Spyder models. I guess not having an AFM and a passive BARO meter really hinders it
