Old Man Posted December 2, 2023 Share Posted December 2, 2023 I have no electricity for exterior and interior lights. Batteries almost new. I crossed the starting solenoid on the firewall and the motor turned over like normal but failed to start. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 2, 2023 Share Posted December 2, 2023 the starter celenoid on the firewall is a main power source to the truck.. check the terminals and cable ends.. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post JoeH Posted December 3, 2023 Popular Post Share Posted December 3, 2023 RD models ran 2 solenoids, not including the one on the starter itself. One on the firewall, one under the dash. The one under the dash runs power to all accessories, gauges, etc. The one on the firewall runs the signal to the starter. Being a 1999, I'll wager you have a Vmac III ETECH engine. If you don't have power to the EECU then you won't be able to start the engine, even if you can get it to crank. Check your fuse diagram for the EECU power fuse. It should have power to one side when the key is in the on position. If not then you need to fix your power fault. I'd guess you have an accessory relay gone bad, given your lights arent working. 3 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 3, 2023 Share Posted December 3, 2023 (edited) Its a CH, still has an acc. relay in the dash, probably a cube style plugged in by the fuse panels, left side.. JoeH, i'm pretty sure that on the firewall celenoid there is a large power wire that goes the the cab, then through the cab relay as you have stated.. With respect, Jojo and yes, My bet is its an E-Tech... V-Mac III like you say.. I forgot to add the on the firewall next to the starter relay there is a black one.. that is a ground breaker.. If it fails, it will cause the issue you have. you can jump the terminals for a minute to see if she lights back up..

Old Man Posted December 3, 2023 Author Share Posted December 3, 2023 adI crossed the terminals on the black ground breaker with the key on and could hear a humming sound from the black box and a clicking sound from somewhere. Had my son hold the key in the start position then I crossed the terminals and motor started and ran for about 2 seconds . I've had the truck probably 10 years but only put maybe 5k on it on a year. You can't offend me, I grew up holding the flashlight for my dad. 1 1 Quote Link to comment Share on other sites More sharing options...
