Ok, so I'm pretty sure that the huge leak of fuel is coming from my bad fuel pulsation dampener. What do I need to do to change it? What is the easiest way to get to it without a lot of trouble? Any help would be great! Thanks

 

Because of the fuel vapors, it is likely that your vacuum hoses have hardened and you will need to do a hose job as well. Many of the wires and connectors will have hardened as well, so handle them gingerly.

You will need to remove the UIM (Upper Intake Manifold), the ACV (Air Control Valve) and disconnect the solenoid wiring harness so that you can push it out of the way. Replace any paper gaskets with new metal ones and any metal gaskets that are badly flaked should be replaced as well.

This job is do-able, but can be very frustrating. If you have a good attitude, then it shouldn't be a problem.

 

Without a lot of trouble? Sell the car.

ALL you have to do is remove the intake plennum, the coils, disconnect the fuel lines , remove the rats nest and remove the primary injectors body. And remember where you pulled all the vacuum lines from. (Mark them with some tape, etc.) If you have not replaced your vacuum lines, this is the PERFECT time to do so. Just make sure not to break any of the nipples off of the selonoids. The part is about $120 from the dealer.

Hope you are not driving it at all!

Good Luck!

 

93MB, I just went through this when tearing my car down to find my coolant leak, which was the TB coolant hose to the block. I would suggest taking this to a shop to have done. Get the FPD changed and a vacuum hose job done.

Unless, however......you have a ton of time, a place to work, patience, some mechanical skills, patience....and patience.

Mine ended up going to a shop..which now created a larger problem with my turbos

 

Amen on that. Doing a rebuild myself and priced a engine harness from mazda at around $400 which I'm going to need

 

This might be a stupid question, but what are the symptoms of a failed pulse dampner. I think mine is bad cause its flooding out real bad. Could that be a cause of a bad pulse dampner???

 

After doing this job, the biggest PITA is those phillip screws.
even bought that craftsman screw out...did not work for me. The tools that worked for me are chisel, punch and a hammer. the best tools ever!

 

The FPD failing shouldn't cause the car to flood more often. Typically, there are no performance problems caused by the FPD. It usually cracks and develops leaks so you get fuel odor from the leaky fuel.

 

I used a phillips screwdriver bit in a 1/4" ratchet. Mine came right out after breaking them loose.

 

Pull the coil assembly and unbolt the entire rack support from the block, that way you can work on the phillips screws on your workbench, should you need to loosen them at all.

 

You gottea get passed ME!!
