In the morning it starts right up. After running it for a while, and letting it sit for a while, it takes alot of cranking to start. Like 5 seconds. Also, every once in a while I smell gas. I have a nitrous system from Nitrous Works, and the solonoid for fuel goes into the schrader valve on the rail. Also I have an AFPR. Any other ?'s? I'll answer them to the best of my knowledge.

 

Sounds like your A/F ratio is okay for open loop ...but when in closed it is going rich for a reason

 

Open/closed loop AF has nothing to do with this problem.

How high is your fuel pressure set? It affects cranking fuel (maybe too much when warm).

Do you have a pressure gauge? Maybe there's a problem with the fuel pump relay when warm, and it's using the oil pressure to activate the fuel pump instead.

Could be leaking injectors flooding it a little at key off, and not giving it enough time to dry out overnight.

Could be many things. Get a pressure gauge, and start diagnosing.

Good Luck

 

I'll try that, thanks.
