Hard time starting when cold, cant give it any gas pedle input, when it starts it does not rev up, engine compression is good, ive looked at the ecu and found it bad (burn't cap & has the smell). Found another ecu out of junkyard, same car & engine but it does not have exactly the same ecu components inside. That somewhat fixed our problem at first (started up alot easyier & didnt die with gas pedle input. We live in cold climate, its getting colder and its getting harder to start agian. im sure its something to do with cold start but i dont know where to look. thanks for any input.

Bad plug leads can also cause cold starting issue. Also a leaking fuel pressure regulator can make terrible cold starts. The fuel pressure regulator will leak large amounts of fuel into the intake plenum , via the vacuum supply line. faulty TPS can sumwut cause this issue also.
