1990 geo storm sohc is running rough. Parts that are new: cap, rotor, plugs wires,plugs, pickup coil, and the ignition module looks brand new. The coil is old, but is still sending spark through all the wires(spark plug simulater). The cam at 9 o'clock, and the crank on "0" on the cover, and the firing order 1-3-4-2 counterclockwise with the rotor pointing at the #1 plug., it won't start. But if you take the #1 plug and put it in the #4 on the dist.cap, and the rest so on counterclockwise, it will start, runs rough like on two cylinders. The fuel pump is charging up like its suppose to when you turn the key.
The timing is 180 degrees out so ignore where no 1 lead should be and rewire the HT leads to the new position for no1 cylinder. The crank timing mark should be on 10 degrees advanced. Engines are timed off the crank position so forget the cam position.
Or you can start again. Remove no 1 plug and turn the engine over until you feel compression under your finger over the plug hole. Set the timing on the crank to 10 degrees before tdc. Position the distributor so that the point of the star is directly opposite the exciter coil in the distributor. The rotor button should now be facing no 1 cylinder plug lead adjust the HT leads so that they will fire in the 1342 firing order. Start the engine and with a timing light attached to no 1 plug lead adjust the timing mark to specifications by turning the body of the distributor.
SOURCE: 95 Geo metro will not crank no fire
take your timing cover off have a friend look to see if the belt is moving while you crank the engine i would say that the belt is broken
SOURCE: 93 geo storm starting problem. turns over but has no spark.
thts weird possibly could be ignitor
SOURCE: 1991 geo storm only runs on 2 cylinders numbers 2
think it could be the amplifier , thats the bit that de codes the signal from the crank sensor to the ecu,
SOURCE: 1992 GEO Storm Crank normal
Do you have voltage to the positive post of the ignition coil with the ignition key turned to run? You do not mention that you have done any testing for system fault codes either, this is a very important test.
