hey guys. would one bad glow plug stop a truck from starting? i just tested all mine with a testlight and one plug is bad. im going to test all of them with a meter now to check ohms bc ive heard a testlight can read a good plug when its actually bad. and also how would i check the glow plug relay? just because the plugs might be good doesnt mean there getting the juice right? lol
