Hi, My 1990 240 5-speed wagon will crank, but no spark. Was running fine when I pulled in at home the other night. The only gauge lights that come on when key is in On position are Service, Check engine, and the yellow arrow on the far right that I think is shift position. Usually all the various lights come on in the pre-crank test display. The coil is hot at the primary terminal in that key position, but no spark at the secondary when cranked. The coil checks out ok with the proper ohms. I would guess the instrument problem and the no spark are related, but my manual isn't much help with that question. Thanks for any tips, Chris
