cold start not in open loop/ fuel pump Q

[mk3tattoos]

when i start the car the A/F's start to go to 14:1 after 4sec, it used to stay in at 11:1 and slowly go up as the rpm's come down from 1900rpms and then idles at 750rpm's. if i touch the gas after it goes to 14:1 after the 4 sec it will go rich to 10.5 to 11:1 but then goes back to 14:1. is this a problam or am i being over worried about it.

i have one more question, when you first turn your key, should i hear the fuel pump prime? i hear it prime after i turn the car off, its a walbro 255.

I hear my Walbro prime when the key hits the ACC position.

my car never raises its idle much for some reason or another (1000 start up/ 800 warm), even when it's cold outside, though that may have something to with the tuned ECU/AFC.. when it first starts, it's somewhat rich ~11-12, and then it moves to ~14.7-14.9 when warm.



hopefully others will chime in.

im not sure if thats a problem that i dont hear it prime but it seems very strange that it does not, it did not prime with the stock bosh either. is there a way to make the pump prime manually to test it?

i turned the key to the ACC position and went to see if i was getting any voltage to the pump and i was not. so i put a jumper in the diagnostic box on fp and b+, and i heard the fuel pump turn on. what should i check next to see why the fuel pump is not priming when i turn the key to ACC.

i would just leave the jumper in, but i have the innovate wideband and i have to wait for the sensor to heat up, and that would leave the fuel pump just running the hole time.
thanks for any help!

I'm hoping someone else with better trouble shooting skills than me answers the question.. I apologize for my relative lack of knowledge on this issue.
