95 Park Avenue Ultra dies for no reason I can find, I've replaced the crank sensor, cam ssensor, spark module, fuel filter, I've had the injectors tested, fuel pump tested, plugs & wires t


As you have probably figured out by now, you will have to treat it as a no start and troubleshoot it when it fails to start. Until you figure out if you are loosing spark or fuel to the injectors when the engine dies you have no direction to go in.

1991 park avenue will start but shuts down it will not stay running. replaced fuel filter still will not stay running


Check to see if the security light illuminates on the dash when it is not starting. If the key is forward and the security light is on, you have a problem with your vats security system. If this is the case, check out this link http://newrockies.com/passkey.

1991 Buick Park Avenue Ultra dies while driving. replaced crank sensor, coil pack wiring harness. oil pressure guage flies back & forth


It is most likely a sensor. It is common in these. You may check them with an ohmmeter.
You may also test relays the same way.

A vehicle needs gas and spark to run. One of them is not getting to motor. You can check fuel pressure on test port on fuel rail for fuel.
You can pull off a spark plug, plug it back into wire, lay it on top of motor, have someone else crank, while you watch for spark, Put back in, move to next plug wire.

The check engine light stays on even after I was told the oxygen sensor needed to be replaced on my 1991 Buick Park Avenue, what else could be the problem?


After repairs are made you must locate a small box in the middle of the speedometer cable under the dashboard and, press a button inside a tiny hole in that box with a small screwdriver this resets the light as, the light comes on only because so many miles have been driven

Car Misses after replacing the coils and spark plugs


Has the service engine light come on? If so, have the codes pulled and it will narrow down the cylinder that is causing the problem.
If no service engine light, have you narrowed it down to one cylinder or is it random.
Let me know and we will go from there.

Check engine light


Check all of the connections to the ECM--twice.

Be sure the four-letter code on your replacement ECM matches the one you removed.

The ECM relies on calibrations performed on some sensors while at the factory. For that reason there may be a switch or a sensor that is reading out of range.

If it seems to be running fine, drive it for a while and get an accurate measurement of MPG. Poor MPG will indicate that things like O2 sensor, MAP/MAF, TPS, IAC, IAT are not reading properly. Check for codes with a OBD-I reader.
