truck has no bus checked all grounds and fuses.there is 12v power to the lt green wire at the fire wall was told that is what feedsw the pcm power,cluster not working either lights up and all then gos to no bus. but the asd relay is going nuts as soon as you turn the key on checked voltage there it has 12v also. im stumpped? anyone have any ideals..
 
i am having similar issues, esp with the asd relay clicking. try putting a big battery charger on the bats to top them off. on my truck the alternator isnt charging and my relays stopped clicking after i had a full charge on both batteries. could be pcm, cps, did you check the large common ground behind the drivers side headlight?
 
Pull the plug off your ecm and clean it with some di electric grease and see if that helps out.
 
checked all the grounds and cleaned them today and still no luck.ill try charging the batts next. and clean the plug and see what happens.
 
you work on things yourself??

dont have your money to pay someone to do it for me.:shake:


took apart the fuse box under the hood. the ends on the engine control 20amp
fuse wires were smucked up cut them off put new ends on. runs like a top again.
