I have a 1987 GN that I bought new, but have not driven so several years. I do drive it around the block occasionally to keep it going, but it kept running rougher and rougher until it would not start anymore. I have no spark at the plugs and no spark coming out of the coil. I also do not have an SES light when I turn on my ignition. I have read several posts about trouble shooting this problem, but most are over my head. I did hook up my OTC Monitor 4000E (don't make fun of my ancient technology - it is all I have) to the portal and pull of the following codes in the order of most recent. Could someone please look at these and give me an idea what I need to replace? Code 55 (ECM Error); Code 52 (Cal Pak Error); Code 51 (Mem Cal Error); Code 45 (02 Rich); Code 44 (02 Lean); Code 43 (ESC Ckt Error); Code 42 (EST Error); Code 41 (Cam Sen Ckt Error); Code 34 (MAF GM SEC Low); Code 33 (MAF GM SEC High); Code 32 (EGR Ckt Error); Code 31 (Waste Gate SOL Ckt); Code 25 (MAT/IAT Ckt Error); Code 24 (VSS Ckt Error); Code 23 (Waste Gate SOL Error); Code 22 (TPS Ckt Volts Low); Code 21 (TPS Ckt Volts High); Code 15 (CTS Ckt Volts High); Code 14 (CTS Ckt Volts Low); and Code 13 (02 Ckt Open).
Any help would be appreciated.
