Question about 1991 Geo Storm

1 Answer

Lack of power and aweful gas mileage

I had just replaced all of the ignition components like the coil, distributor cap and rotor, and i have a brand new alternator. but ever since i replaced these i have only gotten around 8-12 mpg in the city but great mileage on the highway. Also it only has good torque before its warmed up. as soon as the engine warms up it barly accelerates. could it be that the distributer timing is off?

1989 chevys10blazer won't start turns over but won't start one mechanic said it jumped time another one said ignition. Coil or distributor cap put gas in carburetor but it still didn't start


Pull off a spark plug wire and ground it over the engine. Crank the engine over and see if there is any spark from the wire. Sounds as if there is no spark to light the fuel you are putting in the carb. If no spark, possible ignition module/pick up coil inside the distributor/defective distributor cap/rotor/ignition coil/ wiring

Car started and ran fine, quit while driving and now there is no spark and turns over.


Hello first of all

In reading your issue at hand not having no spark there is only a few things that can cause this being that its a 1988 car i will list below what you need to go over and check.

1.spark plug wires
2. distributor cap
3. ignition rotor
4. coil pick up
5. faulty distributor

That being said most are a easy and cheap fix plug wires run about 20-35 bucks autozones duralast brand , distributor cap runs between 7-18 bucks , ignition rotor 3-8 bucks , coil pick up about 15-30 bucks all at autozone.

Now there is no real way to tell if there bad but a good examination of the distributor cap and rotor should tell you corroded inside cracked worn down.

i would start with distributor cap , ignition rotor, coil pick up if the car starts after this replace spark plugs wires. If that does not fix it most likely you distributor is faulty itself.

i hope it helps if so could you leave me so 4 thumbs up feedback thanks so much

Motor will turn over getting gas but is not getting fire to the sparkplugs


A complete lack of spark in a modern car can be any of the following:
-Ignition Fuse
-Coil (or coil pack)
-Coil wire
-Cap / Rotor (or the screw holding the rotor down)
-Ignition Switch
-Main or Ignition Relay
-Timing Belt Broken
-Distributor Gear sheared off
-Cam Sensor
-Crank Sensor
-Shorted or Open wiring fault
-Theft Deterrent System
-PCM / Computer

You need to find the proper test procedures for your vehicle (buy a shop manual) and work your way down the list until you find the broken part.

It stalled and won't start. It has gas, the battery is fine, I changed the spark plugs. I did get it to start rolling it but it soon died again. When it was running in sounding like it was arcing.


most common problem : igniter , distributor cap and rotor.
Open distributor cap , look inside.
probably cheaper to replace distributor assy. , as it comes complit unit with coil , igniter , hall sensor , cap and rotor.

I have a 1996 GMC Jimmy with a 4.3L. The car is hard to start after it sits for the day. I found an oxidized distributer. I sanded the posts and it ran fine for about a month. I then replaced the...


moisture in your cap causes oxidation. You should check to make sure the seal for you distributor between the distributor and the cap is still good. Also a faulty ignition system such as a problematic coil or high resistance in your ignition wires can lead to ignition related problems. Doing a partial tune doesn't always work. Do the wires, plugs, cap, rotor, fuel filter, air filter, PVC valve and depending on the mileage the ignition coil.

Poor gas milage


Poor gas mileage can have many roots but the best way is always to start with the ignition system. Have a look at the sparkplugs, if you've got the I6 4.0 engine it is easy to check them. Spark plugs are cheap and easy to replace. Also check the spark plug wires, be sure the connections are tight and free from rust. Check the distributor cap and rotor and if they are rusty/greasy clean them up. After you've cleaned and checked the ignition items (spark plugs, wires, distributor cap and rotor) you can move on to the fuel injection system.
Replace the air filter, it is cheap and most people overlook that single item.

When was the last time you replaced the fuel filter? A clogged fuel filter reduces power drastically which in turn affects fuel mileage.

93 ford probe no spark,gets gas,checked compression replaced cap


you should check power at each one to verify that they have power, which engine do you have 4 or 6 cyl? the 4cyl the coil is seperate from the distributor and the module is located on the side of the distributor, the 6cyl it is all inside the distributor, but to replace parts without verifing power is not cost effective. The most common ignition failure is the ignition module, but you still need to verify that it receives power.
