I've been experiencing hard starts constantly on my car for the past few weeks. I've gotten new injectors 2 different times already. The first set I thought was leaking after the car was off and causing fuel to leak into the cylinders, then got these new GP Sorensen injectors and still had the problem so i doubt theyre the injectors. I also have a new fuel filter as well if it makes any difference.
Then I thought it was my FPR (Fuel Pressure Regulator) since I smelled gas in the vaccum line going the the FPR itself so I replaced it. (might as well since it was old as hell)
I've taken out my spark plugs already to see if they smelled of gas or were covered in fuel at all and they werent but I could smell vapors from the spark plug holes/tubes so no idea.
Then, I decided to replace my PCV valve anyways since the one on the car was old as shit and let me tell you, it was a big pain in the ass. The thing would not pull out and the grommet wasn't even rubber anymore it was hard as shit. After cutting into it for about 2 hours I managed to replace the PCV and grommet successfully. But I could smell gas coming from the intake manifold where the PCV valve vacuum line connects to.
Furthermore, I got my battery tested at my local Oreillys since the battery was from 2009 and it was low on Cold Cranking Amps, it was at about 350 ish and its suppose to be the in 600's+ but the overall battery checked out fine. I will replace it anyways soon but that doesn't explain the fuel smell coming heavily from my tail pipe on startup.
I'm stuck on what to do next on this issue because I still have to get my lude to pass smog and don't want to be running rich or anything. I have a new Denso Oxygen Sensor waiting to be put on along with my pacesetter tomorrow since I finally gotten all the parts in the mail.
Any ideas or feedback is greatly appreciated as always. Thanks!
