Geo Tracker will crank over but won't start
#4
94 2door tracker, the Cal cars are all 16v but not federal 48 cars in USA< I can not speculate as to what engine you have. sure 1.6L but what head?
how many injectors do you have.

is the car in fact a 8valve TBI engine car. or 16v MPI?

i think to get cel work first, this is best plan on all cars 89 to present. what if it has critical failure information?
the ECU does not send voltage to the CEL lamp.
the ecu can only ground it ,
the lamp has 12v on once side of the lamp and the ecu grounds the other side and bingo, it glows.
i have a good schematic for this.

weak spark can just be a low battery, the starter overloads a weak battery and spark is weak. charging the Bat. to 12.6v (room temp spec) will solve that. this is not HEI , not like new car,
is medium power ignition, good for .028" gap spark never or .050" like new cars.

i wish i knew for sure what engine you have.?

ill guess as 8v TBI 8v and show a drawing.
see the 12v on top the ecu ground the CEL, the ECU grounds this lamp at pin B13 (this is the simplified drawing only for 8v, ) Suz calls the B13 and GEO /GM A13 (a silly GM trick)

now details. (all seen on my schematics page)
the ecu pin

the cluster wiring. see page one here, this is exactly what you have every detail.

one of the ways that the eCU tells you, that it is sick , is NO CEL ! or stuck on all the time.
CEL glowing key on, means the ECU did its self checks and its happy, so far.......

to test the lamp is easy.
unplug the ECU connectors, and ground the Violet-yellow wire is , CEL. (violet body with yellow stripe)
the connector with the large pins is power and is green and the CEL wires to pin 13 on this connector. GM A13
here is the actual FSM page showing how to test this CEL pin..
its clear.
Keep in mind GM calls this A13 and Suzuki B13 , and the wire color is the #1 clue. If i only know what engine you have or the VIN?? all this gets easy.
