I have a 08 evo x with built engine. One day the car just die on the highway, it won't start. I got it tow to the shop, when the car arrived to the shop, it starts again. First thing it came to mind must be the fuel pump. But I replace the fuel relay first, which it doesn't work. I order an arm fuel pump which is what I'm currently running. It still won't start, the spark plug got oil bathed, so I replaced them as well. I check the oil line to the engine to see if there was any gas oil going into the engine, which was fine. I then replace the crank position sensor, the car finally runs. But 2 days later, the car won't start again. WTF, anyone know why?

 

Why is the spark plug getting oil on it? Only a couple ways that would happen, and all of them aren't good.

Have you done a compression and leak down test?

 

Compression test and leak down won't effect the starting. Two reason that will affect starting of a car, ignition and fuel. I replace all of them, that's why I stuck.

 

Welp, sounds like you have all the answers, good luck!

(pssst. spark plugs aren't supposed to ever have oil on them, that has nothing to do with ignition or fuel)

 

Omg

 

 

(pssst: oil-fouled plugs are hard to start )

 

lol, engines don’t need compression to start? You ask for help then tell people they are wrong for helping you diagnose your problem. Just so you know, you’re wrong.

 

sounds like you need to replace the operator.

for real though, you need to upgrade your humility module if your going to be asking for help on the interwebs.

You need four things to get an engine started/running. Fuel, Spark, Compression and good timing. If any one of these is off, then you'll have issues. Good luck.
