Lets start with this. I've changed my starter like last week. It was the problem because I pop started it and it worked fine. I drove to maywood mitsubishi to get a new starter. The car now started like a champ again. Like never before.

Now, the car won't start!!! Can someone guide me on how to diagnose this problem?

It cranks, but just won't ignite and stay on. I believe it is the some kinda problem with ignition because I pull the plugs and its wet of gas there. Also, its a little oily too.

I've got new optima battery and starter right now. I've also checked all the fuses in the engine bay and under the dash. Coil packs are going to be tested tonight. I guess try to see if they spark. What happens if they don't? Where do I fix that?

I've also checked the compression and its 170-180's. Coolant is fine and Oil is good.

The car is has

AEM EMS
880cc injectors
50trim turbo kit
revolver cams
HKS DLI
Stock HG with arp headstuds
and a buncha other stuff.

Lastly, something strange happen before. I got it too start before and stay running. Then the A/C compressor started burning. Kinda like the pulley rubbing metal on metal. So I shut the car off. Now, it won't come on again.

My friend says its could be a blown headgasket because the plugs get oily and stuff.

Before I take it to a professional...I would like some input.
Thank you soo much.
