Cant find info, cold start problem help
 

Hi rx7 lovers,

I recently got a 92FD S6, single turbo running std ECU. I was concerend about this so didint do many Ks till could afford upgrade but it was running/ starting mint in any instance.

Got coin together and got a link G4, also put in rev limit to 3k for low oil or fuel press, changed plugs, lost emissions junk, boost solinod on swith (10psi and 14psi settings), comp check 110/100 I think and had to get new fuel pump cause pressure was dropping of at high boost, new fuel filter and dynoed at a repatable place ( out of my town so not so easy top pop in and ask them)

They specificly kept for extra day to ensure cold start was mint. and when picked up guy told me turn key, listen for fuel pump, turn off and do again before starting to ensure good line pressure.

Started good when picked up and was cold but had been running that day.

Get home, few days later trying to start when stone cold and near run battery flat, if give some throttle seems to start a little quicker but then get back fires and excess fuel etc, still starts no prob when warm and also idol seems fairly steady ( never stalled)

Starts ok if cold but been run earlier that day but when been left o/night/days and is stone cold i have this probelem.

I also noted that the battery had been getting a lil sad when left for days so had tried starting with full charged jump pack attached to ensure that this wouldint be the problem. Any suggestions would be great, I wanna take back shop but its far away and just a pain really.

Cheers
