Question about 1994 Oldsmobile Ninety Eight

2 Answers

Car frequently dies while driving.

The dealer is unable to determine what is defective. Their research indicates it may be a faulty computer, power train control module or a defective ignition module

They replaced the crank shaft sensor. But it did not correct the problem.

Both repairs are expensive for a car that is 14 years old and I would like to obtain your opinions regarding the most economical and efficient remedy.

Please advise.

    I have the same problem. Check engine light usually goes on but turns back off after car is stopped and restarted.
    Another problem is the brakes seem to slip when almost stopped and then grab with a lurch. This seems to happen less when I turn off the Traction control.

Hi,sorry i was not able to find any other Fixya experts to help with your problem, but I can offer some other generic faults which would cause the symptom you describe.
Most modern cars which use electronic fuel injection and ignition have basically the same components so here we go..

1) Fuel pressure, the fuel pump can cause intermittent shut down of engine as this unit works with mostly unfiltered fuel.
Try starting engine and closely listen to pump which is fitted inside fuel tank, if you here loud humming, this is usually a sign that the pump is not 100% and may suddenly seize, cool down and start running again...can be a little tricky to check, also if you can drive vehicle and fault occurs, fuel pump will only run while engine is running and also approx 10 seconds after ignition is turned on, so you will probably need some else to switch ignition on while you listen.
2) Air flow and throttle position sensors are very hard working components of the injection system, the problem is that they are very difficult to diagnose particularly with the limited information I have to work with in this situation.
3) Ignition system has computer, crack angle sensor and many other too many to mention, but I have found the most common is coil pack/s or ignition power supply solenoid.(The one that clicks in engine bay when ignition switch is turned to the "on" postion.
P.S If you can forward a more detailed descrition of what happens when the vehicles fails maybe I could shed more light on the matter.
Regards MMP

    thanks ,when engine is cooled down it will start right away and you can drive like 30 -45 minutes ,temperature will be normal at gauges ,and will shut down ,i've checked on my watch and have to wait for an hour and will start ,i've also checked on the fuel pressure valve if gas is pumping when it shuts down ,it 's pumping gas normal to the injectors ,i thought the solution was to replace the crank shaft sensor ,but i was mistaken

My car dies while im driving

Hi Infamous, I suggest you take the vehicle for a diagnostic scan. The most common causes of your problem are a blocked fuel filter, an intermittent or defective fuel pump, defective crankshaft sensor, but without more info it's difficult to determine. Regards John

My 2001 Jeep Grand Cherokee started knocking. Multiple local mechanics determined it needed new motor. A "reman" motor was puchased ($3600) and installed. On test drive the car ran great then...

All I can say is do some research online find a REPUTABLE shop and let them drive it until it dies. Three things are needed for an engine to run: spark, fuel, compression. I doubt it is a compression problem being that it is a new engine. Something is causing either spark or fuel to drop out, a good mechanic should be able to quickly identify what is missing from the equation. Find a shop with a lab scope that can test sensors that send signals to the engine computer. It could be as simple as a fuel pump getting hot and quitting. Good Luck!

Car has to be jumped frequently, multiple batteries, and dies when driving

I hesitate to suggest this, but it does work well. After you start the engine, and while running. Unhook the negative battery cable. If the vehicle stalls, you have a bad alternator.

91 Accord Car will initially start then when driving it will die sometimes starts right away sometimes 10 or 20 minutes later but has gotten more frequent about dying and taking longer to start

I have a 1991 honda accord dx that had the same problem. while driving it would just completely shut down. after about 5 minutes it start and run for a while then shut down again getting more frequently. There was a recall on the ignition control module (ignitor) which is in the distributor. call your local honda dealer with your vin # and will tell you if yours was replaced. If not I bought one from parts store for $60 or you could take a chance and buy one from a junk yard. I bought the whole distributor for $20 as a back up.
