20 Most Recent 1991 Oldsmobile Cutlass Cruiser Questions & Answers


Fuel, spark, air, compression, timing. Essentials for an engine to run. You've addressed injectors (fuel) and spark (plugs and wires), and I assume it's getting air as it is running. The next thing I would do is a compression check. If you have low compression on a cylinder or cylinders, you may have mechanical problems with valves or rings.

One of the following is probably the issue.
1. You have two or more wires connected to the wrong place on the coil.
2. You did not completely seat one or more wires on one or more of the sparkplugs.
3. You have two wires touching or gronding somehow.

First, is the check engine light on ?
You should have a code for the O2 sensor showing the exhaust gas is rich.
Could be a faulty injector, fuel pressure regulator, or O2 sensor.
Even a faulty thermostat would do it.

there are some videos on youtube showing replacement of the lock cylinder on various GM products. from the few i have watched it is more of removing the cosmetic plastic pieces around the steering column as opposed to removing the steering wheel. if the car has an airbag, you do not want to pull the wheel off anyway unless you are trained.

Either fuel or spark is missing. Pull #1 plug wire and insert a small screwdriver into the wire end and holding screwdriver handle place metal portion next to but not touching any bolt on motor. When turning engine, you should see spark jump from screwdriver to bolt. If so, you have spark. Check fuel, either on the fuel rail by pushing shader valve (Looks like fitting on tire). With key on, should emit fuel. Keep face clear. This will identify which system you need to address.

Have you checked the timing? It is an old motor, and chain could have"jumped" a tooth, or just stretched out.

The fan draws allot of amps (30+) from the alternator which puts a load on the engine, if the throttle valve and idle speed control air-bypass valve are sludged up it will cause a stall because the system can not react fast enough to raise the idle to handle the extra load of the fan, clean the throttle valve and air bypass valve, this should do the trick

yes, but you will also need a source of 12 volts, like your car battery.
Or, you can test it in the car by listening for it to click while someone turns the ignition on.
