Glow plug relay burning
Today i decided im gonna fix my glow plugs. i figured they were my problem, wont start in the mornings if isnt plugged in. tested all 4 on passenger side and all were fine. so instead of pulling valve cover on drivers we figured we'd check the relay first just in case. we figured out the relay was bad,went to napa bought a new one for 80 bucks. put it on, fixed the problem but then the relay started to smoke really bad. the one and two relays in the fuse box under the hood were ticking really bad so we pulled them out and it stopped smoking. with these two unplugged the truck will not start. we are thinking the one and two relay switches are bad or maybe the relay timer under the dash isnt cycling the glow plug relay and just leaving it open. making the relay itself burn out. Just trying to fix my truck and suggestions?
