Question about 1993 Geo Tracker

1 Answer

93 geo tracker gets fuel, has spark, cranks but won't start

Put car back together after it sat for 3 years in a field.... gets spark, fuel in the carb, pressure a little low in #1 and 2 cylinders (70), distributor set at #1 straight on. Getting frustrated-no one can tell me what the problem might be. Have checked fuses; rewired O2 sensor...any suggestions?

Since it gets spark and fuel I suspect the low compression to be a large factor. What is the compression in the other cylinders?

    That is quite a difference. Could be: head gasket, rings or valves leaking. I would think head gasket first as low cylinders are adjacent.

    Makes sense, good job!

Car turns over but won't start. Boyfriend checked the spark plugs , says vetting spark. It says he did a compression check to it. Starter is a year old, battery new, we replaced fuel pump 3 weeks ago...


A thumb is not test for compression as 10lb/sq " will blow your thumb off. Have a proper compression test done. Next although it is sparking the question to ask is it sparking at the right time and to the right cylinder. Pouring fuel into the cylinder is a waste of time as the air/fuel ratio will be too rich to ignite even if the spark was occurring on the compression stroke. So here are some simple steps to follow to get it going
Have a compression test done to determine if there is sufficient compression to ignite the mixture
2 check that the spark is occurring at the cylinder at the right time ( no 1 cylinder on timing mark on compression stroke.)
3 . If it is EFI engine then check that the injectors are actually squirting if carby engine check that the fuel is in the fuel bowl With engines you have to have a combination of 3 things for the engine to work They are compression -which you will be checking for--2 spark timing--- which you will be checking for and lastly 3 fuel into the cylinder at the right time ==which you will be checking for
you only have to be missing one of these and you had best take it to a professional mechanic to get it started.

My 78 power wagon 150 with the 360 four speed tranny cranks over, has spark and fuel going through the carb but no fuel gets to the cylinders, timing chain was replaced and i just got it back together...


How do you know for sure its getting fuel through carb? You can usually see a squirt from the power pump when you step on the gas, but usually nothing else while you are just starting it.

Have you tried to putting a little gas in the carbs before you crank it? Not much and remember.... Its GAS.

You could also try some ether. Its safer and will help dry out a wet cylinder/sparkplug. Just don't use to much of it for to long. If it doen't fire with either then you need to recheck for spark on all the cylinders

I have a 1987 Ford F-150 4.9L Straight Six... it has been sitting on a field for about 3 years. When we went to get it it started moved about 10ft and died. We have put new spark plugs, new spark plug


could be the other fuel pump. they have a low and a high pressure pump. still could be the one in the tank even though its running doesnt mean its pumping. also have the ignition module checked

1986 Ford F150 6cyl, carb., spark good, fuel in throttle, dry spark plugs,...what is problem? Just swapped motors, but same everything except 85 motor.


Because there is no fuel to the plugs I would pull the 02 senor out of the tailpipe and see if the catalytic converter or muffler is plugged. If they are they put back pressure on the engine and not allow the fuel to be drawn into the cylinder and fire.

My 92 geo tracker wont start. All it does is crank crank and crank more. My uncle has it rigged and have no clue what wires go where. So a wiring diagram for it would be nice. We checked everything, it...


Have you checked the fuel regulator and the pressure from the fuel pump to ensure it is not weak. In addition, you might want to check and see if fuel is going into the cyl. the catalytic converter may be plugged based on the year of the car. To check this you could pull the o2 sensor out of the exhaust and see if it keeps running, realize it won't run at 100%. If it is the back pressure will not allow fuel to come into the cyl.

MY 1985 FIERO GT V6 CRANKS BUT WILL NOT START. IT SAT WITHOUT BEING RUN FOR 2 YEARS. IT STARTED UP FOR ABOUT WEEKS AND NOW WHEN I TURN THE KEY ON IT JUST CRANKS BUT WON'T START . HAD FUEL PRESSURE...


More than likely since the car sat for so long with fuel in it that it separated. There is water in fuel and when it sits for an extended amount of time it will rust in side the tank and get into your fuel lines and even your fuel pump. First thing you could do is by some fuel treatment and run it through. it should hopefully break up anything inside there that could be impeding the fuel from getting into the carb.
Also check the leads inside the distributor. when a car sits for that long the seals can dry out and allow moisture in, corroding them and not allowing a spark to enter the cylinder and ignite the fuel.
Just remember that a car needs only three things to run 1. Spark 2. Fuel 3. Air
If you have all of those then the car will should start. Hope this helps. Good luck.
