Yes sir , you have a failing valve, soon it will snap in two....please have your head checked. You can do this yourself by placing a long-handed screwdriver , business end down to each cylinder while pressing your ear to the handle(while engine is running)...you will notice a definite difference when you hit which cylinder has the bad valve. Also makes sure the egr valve is clean and your exhaust recycle valve is not stuck.( located in the crossover pipe)

Engine just shut itself off while driving and starts a a few minutes after


The engine temperature is normal?
If any warning lights have appeared on your dashboard, this may point towards a faulty sensor such as throttle position sensor, Oxygen sensor ..

If you have no warning lights it sounds like a classic case of a faulty/failing fuel pump.

A quick check you can do is to disconnect the fuel line somewhere in the engine bay and turn the ignition on. Fuel should literally spray out.

Before buying and fitting a new fuel pump get somebody - a workshop - to do a pressure check on it/ confirm that it is the fuel pump.

A faulty/failing fuel pump can work intermittently. One minute it's fine, the next minute it stops working.

2002 Buick rendezvous air pump fuse good relay switched with known working one no power to air pump could a bad ignition switch cause the problem ? The key never gets removed.


If you are referring to the suspension air pump, it is automatic and will only operate if necessary to re-level the vehicle. If the vehicle is not leveling properly, check the level sensor at the rear axle for proper operation.

2001 mercedes s500 air ride suspension problems compressor, just replace compressor the old one stopped. Now the new one won'y go off. what should I do to get it to go off the correct way?


Usually when they stop working it is because they have burned out from running too much due to a leak. Sometimes the leak is on the pump itself at the older T line fitting on the side. If it is the new one with the updated line and it is still running, chances are there is a leak somewhere and that is why it continues to run. It could also be the relay. Usually when I replace the pump, I replace the relay as well. Try a new relay, if it continues after that, you will need to have it properly diagnosed by someone familiar with the airmatic system.

Check the suspension switch on the trunk, I think is on the driver side, something should happen if you turn it on/off.

Air suspension is not working


It just happened to me. I took it to a spring shop and had the air bags replaced with coil springs. It is an identical fit from a Crown Vic and only cost $200.00 total! Too much can go wrong with other parts of the air suspension. The ride is the same.
