Question about 1993 Geo Metro
Check out the distributor. You have to remove the distributor cap to gain access to it. The distributor is what fires off the coil in
these cars and also controls the injector pulse. Basically ithas what
is more or less the equivalent of a cam sensor, but inside the
The distributors are prone to failure on these cars. take cap off dist and have someone crank engine over to see if your rotor is turning
On most GEO's I have worked on, there is a thick ground wire that goes from the back of the firewall to one of the bolts on the distributor mount. This ground wire can be "unclipped" in the middle. Make sure that wire is present and plugged together. Also, make sure the distributor signal wire is connected properly down by the rear of the head under the intake manifold.
If you hooked the ohmmeter directly to the two wires which go into the distributor, you should have gotten something like 200 onms resistance. If you get an open circuit on that test; the distributor ignition pickup is defective, and should be replaced. That part is Standard Motor Products # LX755, or Airtex # 4P1221, or AC Delco # D1925D. Those parts cost $75, $78, and $89 respectively at Rock Auto online: www.rockauto.com

Two items, the "ignitor" and the "pickup coil" inside the distributor are the next items to check. Ignitor is more likely to go bad. It can be checked at Autozone for free, maybe other stores as well. pickup coil can be checked with ohm meter. If not shorted or open, it should be OK. ------------ also check pick-up plate . ---------- if the coil is getting proper spark and power.if the spark plugs are replaced and still no spark.please check out ignition rotor.if faulty get it replaced. -------------- also check the connection to the coil to the battery and check your distributor ------------------- thanks.keep updated.please do rate the solution.thank you for using fixya.
