Smoking and gas issues?
Smoking and gas issues?
Hello, first I would like ot thank everyone here ont he forums who have been helping me out with my car. It is back running now, how ever I am still having problems with it. When I start the car a big plume of blue smoke shoots out the back along with a rough idle. The car will idle normal after about 5 minutes, the smoke however continues. The smoke is blueish in tint, and smells like fuel and oil. Which brings me to my next point, the car is also using a lot of fuel. Its using more than normal, and when is low on fuel does not want to run good. It bogs and dies on me. Just recently replaced the fuel pressure regulator, and prior to that the engine was flooded with fuel. Dont know if that helps, but what should I be checking for?

Yup, that would be it...
Sounds like you have at least one leaking injector. Dumps all the fuel into the intake while not running.
You can take em out, plug em into the fuel rail with the little clippy things so they don't pop out, hook it all back up to the fuel lines but not the electric plugs, turn the key On a couple of times to prime it, and see which one(s) drip(s). Watch the FPR fitting as well and see if fuel drips out of it, just in case your new one is bad.

Ive tried to get to the injectors but could not figure out how to get the entire rail off. After putting it all back together the car now runs even worse, when I give it gas in drive it just bogs down and loses power, however in park it does just fine with the engine taking throttle. What could have possibly went wrong?

Re: Smoking and gas issues?
I'm sure you saw the 4 bolts that hold the fuel rail down. Just lift it stright up. On an 87, there is another cold start injector (near injector #5) that you will have to remove in order to lift the rail. You'll have to temporarily reconnect it to the rail to test if the injectors are leaking.

Ive pulled both runners, and the rail still is barely moving, I am lifting on it with more than I know is necessary force and it just wont lift. What could be possibly holding it on? Can someone tell me everything that should be disconnected and the bolt locations?
