Hard starting on cold engine

[skipdownstairs]

I have 255 walboro pump, aromotive fpr, 850cc fic injectors and a stock rail I see alot of these threads that are not going anywhere!! I have noticed on my gauge after I turn the key off the fuel pressure goes down to 0 in less than 2 sec. is my fuel pump bleading off the pressure? and how long should it take for the pressure to drop to 0? The engine starts fine after it is warmed up. I was wondering why it starts ok warm and not cold could it be the isc or a coolant sensor Please help me as much as you can this is very annoying
Thanks, Andy

check to make sure the coolant sensor is connected properly.. that should fix the problem!

It should take hours, not seconds. If the pressure is dropping off immediately, most likely it's either fuel pump/spacer/o-ring related, or a defective AFPR, more likely the first case. Re-check your pump install.

Judging by your injector size, you should have tuning/logging capacity, what is the coolant temperature reading before you start the car?
