I purchased this car for $400 and many things didn't work but that was to be expected. I have replaced two injectors and the engine computer because of a hard electrical short at the time of purchase. My problem is that after these two events the speedometer stopped working. I have checked the speed pickup sensor and all related wiring for continuity and it apprears to be correct and working. There is no signal at the instrument cluster in the dash (but the speedometer comes off bottom on engine start) I can locate only one firewall penetration which has been cleaned and reiinstalled. Any guideance on where to go next would be appreciated.
