1991 Dodge Stealth SOHC Ignition Problem

\015 The engine turns over but there's no spark.\015\012History:\015\012\015\012The car died, wouldn't even turn over.\015\012We tapped the scan connector at pins 1 and 12 initially and the voltmeter reading indicated a bad ECU. \015\012We shipped it to a company in Florida who repaired it. The engine now turns over but with no spark.\015\012With a voltmeter connected to pins 1 and 12 on the diagnostic connector and the ignition on, the needle fluctuates at a steady rate between 2 volts and 10 volts, indicating no codes present.\015\012The ignition coil primary and secondary resistance is correct.\015\012Connecting 12V to the primary and then disconnecting it generates sparks at a plug connected to the coil.\015\012We successfully tested the (Ignition Control Module) using a 1.5V battery to forward bias the power transistor and an ohmmeter to check for a drop in resistance, per the documented procedure.\015\012Questions:\015\012a) The voltmeter indicates no codes present at the diagnostic plug. The There are diagnostic trouble codes for the crank angle sensor and TDC sensor which are part of the distributor. If I disconnect them, why do I still get no codes at the diagnostic plug? \015\012\015\012b) The manual says to "check the distributor". How do you do that? I don't have any special tools. \015\012\015\012c) Could a bad condensor/noise filter cause this problem?\015\012\015\012d) The manual lists a Theft Deterrent system. I haven't explored that yet but could that system kill the ignition without generating diagnostic error codes?\015\012\015\012\015\012\015 Posted / edited by AnonymousUser on : 21-05-2018
