We are having issues at starting,Batts good,,no jump start,key to start and gauages die and the only light on are the park brake and the engine check light,seems it may be the ECM.Seems the same as LPJs issue back in may,any thoughts?
Have you checked the battery ground cable wherever it attaches to frame, block, chassis. (especially if when you jumped it and hooked the ground jump cable to the battery post instead of another ground on yours ..if you grounded it frame to frame this won't apply)....follow it the neg- big wire and see if it's loose or corroded. If automatic try neutral....guessing...
first check that battery wires are clean and connected including chassis ground
Thanks,will do,maybe a list of the ground points on the vehicle would help,is this available on line?We are down here in New Zealand and its Saturday,so its a weekend fix!
Thanks for the chart,the pre heat light doesn't come on when the key is turned to ignition,would that still relate to a bad ground?
Hi ,just to follow up,it was the ECM,so thanks for the help.
