Hard starting after mods??

[kgtalon95]

Hey guys, just installed a b16g and all me fuel mods. Did a REAL boost leak test also
My car doesn't like to start, i have to turn the key for about 5-7 seconds before she'll turn over if it hasn't been driven in like 18 hours. If i shut it down and turn it back she'll fire up right away. Is my starter going out?? I also now suddenly have idle surge between 1-2k, and both started happening at the same time.

I also have a new redtop, so I know its not the battery

PLEASE HELP!!

I noticed you got an AFPR - good job.

One common problem with new pump installs is that the O-ring around the pump outlet neck can bleed out the fuel pressure. This can make it so that when you go to start the car back up, there's no pressure available so you have to wait for the system to prime first, which means that it cranks for awhile. It is very likely that this is your problem if, after stopping the car, it'll start right up, and when you let it sit for a awhile, it's a pain to start.

From the VFAQ:

Be careful when putting the pump up into the fuel feed line - the rubber O-ring should be lubed with some grease, oil, or spit (hey, it works) so that the O-ring slips easily into the feed line. If it does not, the O-ring can kink or tear, and the car will be hard to start after sitting a few minutes, as the kinked/torn O-ring will allow the fuel to bleed out of the feed lines. The symptom will be that the car will take several seconds to start after sitting more than a minute or 2, but starts right up if you turn it off and then immediately start it back up.

If you have a gauge on your FPR, you can tell if the fuel pressure is bleeding down by watching the gauge.

How hard is it to get too?? Would have to pull the whole assembly back out? Where can I get a new o-ring

Yeah, you'd need to pull the pump assembly back out, and remove the pump.

I believe you can get that o-ring from the dealer - otherwise, just a general o-ring from an assortment kit might also work if you can find one around the same size.
