Cold start sr20det help?

[SilviaT]

I have a red sr20det,440 injectors, t28, headers, turbo back with a cat-delete. Its a s13 hatchback with a veryyyyyyy annoying cold start problem. fires right up when warm (after i used starting fluid to make it fire).
Recently had a new: 02 sensor, water temp sens, complete wiring harness, stock sr ecu w/ map, z32 maf.
But still hessitates to start when cold..Compression was down a little also, but was perfect like a month ago before i put it in the shop to have my wiring harness done. So i dont know what to think besides having my injectors cleaned out. Also, 3 of my plugs are fine, but my 4th was coated in oil.....? Recently had an oil change with 10w-30 mobile1 synthetic but maybe a litttttle bit over filled because of stupid jiffy lube.
PLEASE HELP..
Oh, and one more thing. FORGED PERFORMANCE is the shop that is helping me out. they said that the remaining factor that it could be is a bad ring..? That when its cold it has a harder time getting loose, compared to when its already warm and running/starting perfectly fine.

im having the same problem...it starts cold but just take a lil bit of time to crank, also the same issue with the 4 plug being covered in oil...going to swap out gaskets and we'll see what happens.

Bringin up an OLD thread. So i had my engine rebuilt at my local shop that my family has known for a while and who do quality work.. Looks like i had a chip in my 4th piston due to over reving from the guy i bought it from.. Ha. Found out my cylinder walls are fine. I had the block hot tanked, balanced and a valve job. Bought a complete engine rebuild kit including
Forged CP pistons. 86mm 9.0.1
Clevite connecting rod bearings
Clevite main bearings
Clevite thrust bearing
OEM full engine rebuild gasket kit
Apexi head gasket 87mm T=1.5
OEM Sr20det timing chain, tensioner, guides, guide bolts
OEM water pump
ARP head stud kit
and OEM oil pump, and timing chain cover.

So the chip in my #4 piston explains my cold start issue: loss of compression.
I have a TURBO SX dual stage boost controller and i want to run 8lbs during my engine break in process, and after about 1500 miles, hook up the 2nd stage switch to 12lbs.
My question is, how do i turn down my boost and how do i check its level?
Other question is, i have a mapped SR ecu that is running my 440cc injectors, and about 12lbs. Will that be fine with my setup? I'm going for daily driving, but also a healthy reliable engine that will handle some aggressive driving at times, but not all the time. This car is my baby! Ya'll know how it is..
Thank you guys for your feedback i really appreciate it. especially on such an old thread..
