1988 Fuel injection Sign In

At start up my 88 Ranger revs up to 1800 rpm for 3-5 seconds, and also is loping alot at idle. I've checked all the vacum lines multiple times but haven't found anything yet. Would an injector be able to suck air if the O-Ring is bad? The reason I asked is because it smells like gas all the time. All the lines are good, so it has to be from up front.
Thanks

If you can smell gas that isn't right of course. Try starting up cold for just a couple seconds and see if there's something wet on underhood lines/items right to injectors. Injector is under fuel pressure so it may leak down but not really suck in air??

I checked the lines and couldn't find any that looked like they were wet. But i did notice that after I've ran it for about 10 minutes and shut it down I hear a pressure release. psssshhhhh you know? Any way it's real hard to tell where it is coming from. O ring sets are cheap so I think I'll swap those out and check the resistance on the injectors too.


Thanks
