Long cold starts

[BRileyNV]

I recently had my car tuned at a local shop and since then when I do a cold start it seems to take alot longer to get it to fire up. New battery, new alternator new MSD coils and NGK iridium 7 spark plugs. Sometimes it wont start on the first crank then I'll do it again and it fires right up. I'm not sure what it is but any suggestions would be appreciated. Thank you

Sounds like fuel pressure is bleeding off while the car sits. Has the PPRV been removed? Try cycling the key on 2 or 3 times before cranking to build up fuel pressure to see if that helps.

I believe that has been removed

PPRV delete will cause longer cranking times before starting.

That's great to finally know, it's been driving me crazy

I did this on a past car and the best fix was just don’t go from key off immediately to start, key on for 5-10 secs or so and then start it. It cranked right away.
