aerocorey Posted February 29, 2008 Posted February 29, 2008 ...or maybe not. I finally got the truck to not start in a place where I had someone who could crank it for me while I play with the multimeter. With the key in ON and START there was just under 5V at the yellow wire going into the ignition module. That wouldn't be odd on some vehicles, but I don't see on the diagram if there's a resistance wire between the ignition switch and the ignition module on this truck. If it's supposed to be 12V I'll just have to find the resistance that's not supposed to be there and eliminate it.
TNT Posted February 29, 2008 Posted February 29, 2008 Poor connections cause resistance which cause voltage drop. Check the bulkhead connector at the firewall since they have been known to cause problems. You can even test connectors by performing a voltage drop test across the connector.
aerocorey Posted February 29, 2008 Author Posted February 29, 2008 I messed with it again. There's a chance that I'm a retard. There's 2 yellow wires going into the ignition module. I think I tested the wrong one.
