Hello, I have a question, I am replacing the intake manifold gasket and I up to the point of removing the fuel rail. The Haynes manual says to just unscrew the fuel inlet line and disconnect, but I have unscrewed it and it won't come out. Can anyone tell me if I need a disconnector tool? Any advice will be appreciated.

Normally they are hard to get loose as the o-rings holding in the fuel injectors stick. Assuming everything was disconnected according to the manual. Kind of pry up with a large screwdriver. Try each end be careful and don't break anything. If you missed a bolt you will see where it is. When reinstalling lube the o-rings with vasoline.

Thanks rhandwor. The injectors are free, it is just the inlet line that won't come loose. I have pryed pretty hard.

The gas line should have a flare nut that attaches the fuel line to the rail.

Patrick8475 · 10-03-2006, 01:41 PM

It does, I loosenend it, and it is totally off of the rail and just sitting on the line.

I think you have it ready to pull off. If not run your hand along the rail you will feel anything that is holding it. At the end look for a short legged U gas line for each side. Their should be a supply and a return gas line. A vacuum hose for the pressure regulator is this attached. The regulator to a brace. And I think 3 braces for each line. That should be all their is and maybe more than what you have.

Thank you for your help. When I get off work I am gonna try to get it loose.

Success, one blown head gasket and a new IMG and I am good to go. Thanks to all for the information in this thread.

I just replaced the Intake Manifold gasket on my 98 venture also changed my spark plugs. Now the damn van won't start. It turns over but won't start. It is getting spark. When i tried to hold it open to make it start it backfired. I took one of the spark plugs out it smells like it is getting gas so definitely a back fire.The battery is fine. Does anyone have any suggestions?

Patrick8475 · 10-06-2006, 09:45 AM

I am in the process of replacing mine, that is my worst fear is when I get it back together it won't run. Do you have a Haynes manual? I would check all of the electrical connections to make sure they are connected to the right spots. Follow the diagram to ensure they are.

Tree003 · 10-06-2006, 09:54 AM

Thanks for the advice. I did check it but the damn thing is driving me crazy! I made double sure everything is back in order. The only thing I can think of is if The Fuel injectors are not tight enough? I only pushed them down in.

Patrick8475 · 10-06-2006, 09:58 AM

That really sucks. Maybe check for spark, and if it is sparking check to see if it is getting gas. I am replacing it on an Alero, and I had to remove the fuel rail. I am not sure if yours has the same kind or not. I have a pressure relief on the far side of it. Maybe the fuel systme has to be pressurized. Just guesses, but with spark and gas it should run.

I would go over your work it is easy to forget to plug something in if you don't do it every day. I always lube the injector o-rings with vasoline so they go in easier. Are all connections on the air intake tight with no cracks. Is the mass air flow sensor plugged in. temp sensor. Is the injector harness plugged in. Did you remove a ground and forget to install it this is very important. If you have a test light check an injector a test light across both prongs from the harness should flash. Use a flashlight as you hunt for something unplugged.
After you get it running if rough spray around the injector base and intake manifold with carb cleaner if you find a leak it will smooth as you spray.
If the injectors aren't leaking and you were able to bolt the hold down clamps
tight it should run. Did you hook up the vacuum for the pressure regulator.

Double check your plug wires are in the correct order. Very easy to mess up. Mine were numbered before I removed them, but the numbers didn't match the cylinders.

Tree003 · 10-07-2006, 04:52 PM

Thank-you so much all of you! And a very special thanks to rhandwor. The injectors were lose and i did what you said. Worked like a charm. It is running a little rough now so i am going to spray the carb cleaner.Thanks a million!
