Did clutch, car sat a week, now hard to start

[idkiliketurbos]

Hey guys, I just replaced my clutch on my car and it was sitting with battery disconnected and not ran for about a week. I just finished it yesterday and haven't done a ton of driving with it yet either. But when I go to start my car after it has been sitting for a while it takes about 10 tries to start and keep it running. If I finally get it running and take it for a spin and turn it off and back on, it goes fine. It turns over fine, it just dies right away. Also, it seems to idle very rough and low. Now here is what I think it COULD be: I have an upgraded fuel pump with the stock regulator and I can hear it whining now more than ever; or the ecu hasn't relearned itself yet. It smells like it is running rich as hell and I have the stock fuel pump and want to install it, I just haven't got my gas tank low enough yet to do so. I have checked for vacuum leaks and I don't hear any hissing noises like I have in the past from vacuum leaks. Anybody have any thoughts on what it could be?

First of all, if you have a Walbro 255. That is too big for stock regulator. It will over run it and cause it to run a little rich. I think my A/F ratio at idle was 13.X when it is supposed to be 14.7 using the Walbro 255 and stock regulator. So I bought an EVO 9 fuel pump much quieter. A Walbro 190 or EVO 8 fuel pump will be fine too.

I was in the same boat as you about 2 days ago. I just bought an xtd stage 4 unsprung and chromoly flywheel. It was hard to start. Took about 3-6 cranks. Now after about 130 break-in miles and stuck in traffic jam for 2 hours its starting to fire on 1-2 cranks. I think this is why they have break-in miles.

Alright. I was planning on putting the stock pump in the car once this tank of gas got lower but then clutch went out and I had to replace that first and I have about 3/4 of a tank yet. I will get that done asap though and just drive around.

And if my first post was confusing, it starts easy enough, but it won't stay running until about 10 times of starting it and it dying.

UPDATE: I talked to my mechanic buddy and he told me to check the coolant sensor and I found that the wires must have gotten ripped out of the connector for the sensor so tomorow I am going to find one at the junkyard and cut the connector off with some wire so I can wire it up. And what makes me belive this is the problem is that when I finally do get it running that the fan turns on right away and there would be no reason for it to turn on.
