Strokermjcomanche Posted October 8, 2017 Share Posted October 8, 2017 So you aren't getting a signal to trigger the injectors to fire ? I know you said you changed the CPS , what voltage are you getting at the CPS plug when cranking ? Link to comment Share on other sites More sharing options...

DirtyComanche Posted October 9, 2017 Share Posted October 9, 2017 I think you have a ground issue, or some wires melted together, based on the whole bizarre issue with your brake light switch engaging your aux fan. Might want to do a quick visual on your underhood harness, check your fuses and fusible links, and look at all the ground points. Link to comment Share on other sites More sharing options...
carnuck Posted October 9, 2017 Share Posted October 9, 2017 Put a spoonful of fuel in the throttlebody after all else. Then if it doesn’t start you may have a burnt through ignition rotor. I would go after Cruiser54’s Renix maintenance first. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
