I really think your starting problem is the fuel pressure regulator. There is a write up on how to check it and replace it in the tech tips section, with pictures.

~Yes that included $45.00 towing fee. Can somebody send me the link on how to check the fuel pressure regulator? Yup I think next time I go to Mc Cartys Auto Repair Im going to ask them to take me on a date first before they pull out the vaseline

~ Im definatly going to be getting to know my Caddy on more of a personal level so I can access things myself and who knows possibly fix it

Thats the only way I will know Im not going to get screwed.~

~Thanks for all the great info and Im going to be asking quite a few more questions later on when I start inspecting my girl~

Cutie, check the link misfit gave you. No need for a date or vaseline. You can do this yourself.

She still hasn't told us the year of the car.

The vacuum line, maybe plastic with rubber angle connectors, comes from the top of the throttlebody and runs about 8" back toward the fuel pressure regulator (remove the engine beauty cover). If you carefully twist and lift the connector on the little round thingy in the right rear of the fuel rail you'll see the vacuum connector nipple. That connector and the end of the hose you pulled off should (must) be dry.

~Wow I just had a scary experience. Thought my Caddy was going to catch fire on me. I went out to run to the store and took extremely long to crank. The first try it didnt start but when I let off the ignition a loud POP came out from under the hood....and immediatly seen SMOKE coming out too. I popped the hood and under the "Beauty Cover" smoke was coming out. The Check Engine light also came on. She started right up after that....but now the Check Engine light is off. What in the hell happened just now? Does it still sound like the Fuel Pump Regulator? Smoke came from under the Beauty Cover but not exactly sure from where. Is it safe to check the FPR mid day like it is right now? I smell gas pretty strongly~

Shoot my camera batteries went dead before they saved the pics of my FPR but heres the one of the inside of the cover where you can see it burnt/singed the black cushioning inside it.

I will get pics tomorrow. Im a BLONDE so you will have to explain to me in BARNEY terms what youre talking about. I removed the little rubber hose coming out of the top of the FPR and there was alittle wetness of gas there inside the rubber hose. Also my FLR looks to be welded to a metal pipe there. How do you remove it if its welded together to the pipe? I will post pics tomorrow because my batteries are dead and its getting dark outside now.

we are talking about releasing the pressure through the schrader valve on the fuel rail. it will have a cap on it. before you do this i suggest picking up a fuel pressure gauge with a push button to relieve the pressure. it should have a hose with it to drain the fuel into another container of your choosing. there shouldnt be alot, but it's worth having a catchcan for.

the FPR (fuel pressure regulator) should be held on to the rail by a clip. if you remove this clip, it will pop right out with little effort.
my 97 was this way and i doubt your 96 would be much different.

that pop could've been a backfire of some sort. fuel/oil puddling, reversion, ignition...BOOM...likely popped the pressure valve on the intake and the snapped it right back shut...

~Could somebody give me a Carfax on my vin? 1g6kf5297tu297784
Service history etc so I can at least have an idea of whats been going on with my car. ALSO could the recalled fuel rail have anything to do with my problem? How do I find out if my car falls under this recall?~

**Ranger** · #27 (**permalink**) 05-06-08, 11:06 AM

Cutie, Your description sounds like a leaky FPR. There should be no gas on the nipple or vacuum hose. Raw gas is leaking into the manifold. That is what you are smelling and what caused the backfire. Have it changed.

Cadillac_Cutie · #28 (**permalink**) 05-10-08, 12:43 PM

~OK I think I made a boo boo on a very simple FPR test. I de-pressurized the thing that looks like where you air up your tire. Had a rag under it and used a screwdriver wrapped with another rag. An oz or so came out. Then I pulled the little rubber hose off the FPR and turned the key until the lights came on the dash but not to start it. I washed the little nipple thing and after a few seconds a SLOW drip started to form on the tip of it. So I guess my FPR is bad right? ~

~My problem started when I went to take the FPR off. I removed the clip but then all this gas started coming out from under it so I had to hurry and clip it back down. What did I do wrong? I de-pressurized it before doing all of this? Why is there gas coming out of it?~

~Heres a few pics...they arent very CLEAR but just to show what I did. Umm sorry I didnt get a pic of the gas squirting everywhere haha kind of was freaking out and trying to clip it back in place so that my car didnt CATCH on fire haha. My motor was pretty HOT so I was nervous thinking I was about to catch my Caddy on FIRE!~

You can see pics here

~lol OK so I changed out the FPR. Quickest 5 minutes of my life. Wow I cant believe I paid $45.00 for the part and did it myself instead of spending $160.00 for the auto repair place to do it. So far its starting like a dream. Cold and hot starts. Only thing was the NEW FPR only had 1 rubber seal and was alittle different looking than the old one. I started her up and nothing was leaking...so I guess all it needs on the new one was the one seal. The old one had 2 rubber rings but so far this one is doin great. Will know tomorrow....trying to drive her around and then let her sit to see how it goes.

You guys are the greatest! Would NEVER have attempted to change it myself if I hadnt come to this group~
