I recently purchased a 92 SC400, everything's fine except the cold start. After the initial start, it always cranks over good.... let it sit for 4+hours and then try to start it and it sounds like it just won't start, and then it finally does. What could be the possible problem/solution to this?

 

Sounds like the engine's flooding.

Try searching, might come up with something?

 

Might try a can of "BG 44k" fuel injector cleaner.

This brand has had good reviews here.

 

don't think the engines flooding from sitting for 4 or more hours and then starting it.... just put an entire bottle of sea foam in gas tank so i'll post back on results of this.

 

Seafoam didn't result in anything, still had a rough start after work... any ideas?

 

bump...???

 

Have the vehicle professionally analyzed.

 

lol... If I was going to do that I wouldn't bother with the post
