Cold start cranking too long

[bizzo15]

Hey guys

My '91 seems to take longer than normal to start when it sits for a while I've taken a vid of it to post to make sure i'm not crazy. After it runs it will start back up first crank no problem. Here's the video:

I also get an odor of fuel under the hood but I can't tell where it's coming from. I've checked the fuel lines going to the tank and they're a little rusty but they don't seem to be leaking. Where's the fuel pressure regulator located on these TBI motors?

I have them same problem with my 94 suburban,i just replaced the egr and still doing it too.So am going to bump the timing 4 degrees and see what that will do too,i will let you know if this helps or not.

I would check fuel pressure.

EDIT: Just saw the vid and that seems pretty normal for TBI's.

TBI motors release the fuel pressure when the truck is turned off so it has to build up a little more pressure to turn on, IIRC. My Vortec always starts faster than my dads TBI.
