Was driving and my car started to overheat so I pulled over because it shut off while I was driving. Refilled the coolant went to start it again cranks but won't fire. Left it overnight came back for a little bit of gas in it got it to fire up drove it for a block or two then it shut off again. Went and got new terminals and battery got to fire up again drove it another block or two and it shut off again. Now it just cranks and won't fire up. I replaced the terminals, the battery. I test lighted everything everything is getting power up to the coil packs. New camshaft position sensor was installed. I replaced every single fuse there isn't a car with a brand new one. Still cranks but won't start. My key is a chip key and it's broken I taped it and it worked fine for a while. Could that be part of the problem? Now it's not getting spark or fuel. Also since it was overheating in a little bit I checked for water in the oil to see if possibly blown head gasket. I just did the oil change previous to it breaking down on me. Engine oil is still clean no water. Hold the alternator out had it tested four times all came back good. I'm kind of clueless as to what else it could be. One thing to know it's a 2003 Mitsubishi Eclipse RS with an O2 Galant motor 2.4 L 4-cylinder. So the fuse panel doesn't exactly match what is on the car. Where should I go from here? I've been trying everything I can for a week all day long and nothing.

Hello,

Okay, So the vehicle was overheated. Let's make sure the vehicle is getting compression. Here is a link for you to go to down below:

https://www.2carpros.com/articles/how-to-test-engine-compression

When a vehicle overheats usually what will happen is that the aluminum cylinder head and the iron block will cool at different rates causing the aluminum cylinder head to warp. It's this warpage that causes the head gasket to fail causing lack of compression in one or more cylinders. To start a vehicle needs three things, fuel, spark (delivered at the proper time), and compression. Please go through this guide and get back to us with what you are able to find out.

Thanks,
Alex

Also, I have a compression test kit, but I don't have it on me and it's a ways away and there's nothing open I work at 10:00 am in the morning. It's Sunday everything is closed. What would you do?

Hello again,

Okay, let's work with what is available and go from another angle, even though without compression this is irrelevant. Is your immobilizer light flashing on the dashboard when you try to start your vehicle? In the diagrams down below I have included a description of your vehicle's immobilizer system. If there is an issue with your vehicle's immobilizer system a Direct Trouble Code (DTC) will be set, so your Malfunction Indicator Lamp (MIL) or "check engine" lamp should be illuminated. Could you please get the DTC(s) for us. Here is a link down below for you to go to if you are unfamiliar with how to do that:

Please get back to us with what you are able to find out.

Thanks,
