Sup DSMers,

'95 Eclipse GS M/t. Hasn't run since January.

What's been done so far:
- New battery (always charged ready to go)
- New fuel pump/pump assembly
- Cut wire for anti-theft system (kept it from cranking before)
- Made sure CTS was cleaned up and connected securely

How do I know it has fuel?
-Fuel getting to fuel rail at pressure
-Spark plugs appear wet with fuel, but can't confirm fuel is getting through injectors at pressure

How do I know it has spark?
- Pulled each plug, connected it to plug wire and battery cable while cranking and visually got spark (done with each wire)

I've just been guessing at this point, and trying to find little things here and there that may be it but I can't find another thread that has the same or even similar issues, at least with a solution. Maybe I'm not looking hard enough.

Anything helps. I'm pretty novice to this so, I may have easily overlooked something simple. Thanks!
 
If the plugs are wet with fuel, then it is most likely lacking spark or compression. Have you tried new spark plugs? If so, run a quick compression test. Also be sure that the plugs are wet with fuel and not oil... WTF
 
You'll be able to tell if the plugs are wet from fuel or oil, they are each different visually. Smell the plugs as well. I don't remember if the 420A engine has a check valve on the end of the fuel rail or not. The 4G63 doesn't. So if your engine does, push in the valve while someone cranks the ignition. If fuel comes out, you should bee getting enough fuel, but maybe not enough pressure. If no fuel comes out, check the pump relay. If you are checking for spark properly and seeing spark, then the ignition should be fine, and perhaps the compression is down. Test that while doing everything else. You may be new-ish, but at least you're asking for help, and not assuming you know everything and deciding not to ask. Good luck.
