I have posted on this before, my camaro will not start on the first key turn, I have to wait for the alarms to go off and then turn key back to off and then start. I have an SES light. I was told that the fuel pressure regulator is the problem, can it be just taken off or do I have to remove the entire fuel rail, as always thanks for the help.......SFC

 

First get the car scanned and fix the SES problem. You should do a fuel pump and regulator test, as what you describe appears to be that FI system is not retaining pressure when the engine is turned off. This could be due to a bad check valve in the fuel pump, a bad pessure regulator, one or more leaky injectors, or even an external fuel leak (fire danger).

 

Sounds like the pump is in the process of going bad

 

I do not smell any fuel, I had a scan at autozone, it showed bad cannister purge solenoid, I replaced it, it also show a bad fuel pressure reg.will this clear up the ses? I know it is not alot to go on, any thing can help thanks.......SFC

 

The fuel pressure regulator has to be replaced entirely. My car did the same thing, ended up around 350$.

 

this is a 50 dollar part on the fuel rail, if you have not done this or know how to do this please do not respond........SFC
