Slow start and jumpy on startup until warm

[TTUhouston]

So, this just started yesterday but for the first startup of the day is super slow. When it does startup the idle is pretty bouncy for a few seconds. If I rev it for a sec it is normal and i can turn the car off and it starts right back up. If I try to drive it bogs first then goes until its warm.

To me it screams fuel maybe a leak or something in my new setup or at the fuel pressure regulator? I dont see any drips anywhere so it seems fine. Going racing tomorrow, car runs great once warm. Any ideas?

How many miles are on the car, and how long was it between now and the last time you drove the car?

This happened to me a few times after changing fuel system. Dont know if same issue. I started to turn on car with out cranking it for 10-15 seconds everytime. Fixed issue & never happened again.

hah that is the same thing I have been doing today. I prime fuel pump once, turn off key, turn back on, and it starts fine. Funny!

Yeah I sit there for 15 sec until I hear everything up & running, then crank it & issues went away.

Cars on E85 have a harder time starting in cooler weather. As we get deeper into fall if this gets worse contact your tuner. They have a few tricks they can do to help it fire faster.
