Trying to find ignition relay module , 93 tracker, will crank but no spark, was suggested ignition relay is bad, just can't find the darn thing. sometimes no power/ just loud clicking noise under dash,

In the circuit between the crank position sensor and the coil packs, is the ignition control module. It not only amplifies the crank position signal, but also does things like set the ignition advance curve as rpm goes up. It is expensive, but could be bad. First check to see it it is getting power, and it is not a fuse or a relay before trying that unit.

Yes, the ECM is the last thing to replace after all other possibilities. No spark could be bad ignition coil, bad Ignition Control Module (controls the coil circuits for spark), bad plug wires, the crank and cam sensors (for ECM to determine spark timing).

Check the ICM -it can be tested at a parts store. If good, check the crank sensor.

still bad?
ask for help ,
we have all data on GEOs.

did you check for spark first on all 4 cylinders>?

the ignitor model never fails, 1 in a million
on the 91 ( i have one)
INSERT the diagnostic jumper
crank the engine or 5 second,the flash code will tell you
bad CMP or bad spark if the ignitor is dead, the ECU sees that
and reports that.

the jumper is here. full docs

Suzuki (it really one)
move the jumper every few years, to keep us intertwined.
all jumpers are here.
yours is next to front battery.

Can we assume not a single thing was tested,
& you have no idea, if even one of those parts failed?

You need a wiring diagram & knowledge of how to test any
system or part of it- your trying to get working,installing part
after part- is not a solution

At this point I would suggest a repair shop

Have you checked for fuel and spark? Listen for the fuel pump to buzz for about two seconds when the key is first turned on. No buzz could be a bad pump, relay or PCM fault.

Check for spark. No spark maybe the coil or ignition module.

There are plenty more things in each system to go over. It helps to start eliminating the obvious and go from there.

After you have checked for spark and fuel, get back with me and I'll see what I can do.

4 possibilities 1 crank sensor, 2 ignition control module, 3 ECM, coil/ coilpack. Check codes first this will point you towards the right direction.
If there are no codes then go to the coil/ coilpack

I'll tell you four common failures on 90-93 Accords: 1.) The PGM-FI relay goes bad cutting power to the fuel pump. 2.)The distributor ignitor goes bad cutting spark. 3.) The ignition coil goes bad cutting spark also. 4.) The electrical portion of the ignition switch goes bad cutting power. (Quick check: try wiggling the key in a circular motion while its running, if it dies the ign switch is bad.) Note: Watch the distributor rotor while cranking. If the rotor turns while cranking than the t-belt isn't broken.

could be crank & cam sensor if they do not meet in sinc they will not get spark

Is it not getting spark or gas? It needs both to run. Both main source. If no spark in any cylinder, then ignition module or crank sensor is likely faulty. If no gas, then fuel pressure regulator or fuel pump or fuel pump relay is bad.

makeminelgd,

Did you find a solution to your problem? I have the same problem with my 93 Tracker. Help.
