Just picked up a 98 gsx limited that I’m trying to get running. I have a no spark condition that has me stumped. Original mpem would not power up gauges but would allow crank but no spark. Replaced mpem with arialtek reman unit from eBay. Gauges now work and I’m getting 2 beeps with key. Neither mpem have powered the white wire to the coil (I’ve checked coil terminal with volt meter and light and also pierced the insulation with light before coil box connector and just coming out of mpem). White wire ohms 1.1 from coil to mpem connector.
—retensioned the pin without any change.
-Trigger coil ohms within spec (278) to mpem and bracket is intact and sensor is clean
-Coil produces spark with bench test and passes all resistance checks
-Fuses are all good and I’ve removed and cleaned grounds on mag cover and in coil box.
Edit: worked on it a little longer and am getting 12v low alarm on gauge while cranking. I am measuring 12.3v on mpem fuse while turning over. Also not getting an Rpm reading while spinning over. Confirmed flywheel is correct for a 98 with 2 trigger pickups.
What am I missing? Thanks
