checking for spark on LS1?
#3
but would i still be able to see spark if i just grounded it to the head? im trying to figure out why it wont start. i know im not getting fuel past the injectors for sure. they sat for a LONG while but i boiled them for about 20 mins and that got alot of crud out. my question is even though the motor isnt firing up, would the porcelin portion of the sparkplug near the tip still have brown marks if the plugs were igniting but the motor not being started? my plugs were brand new but i pulled them and looked at em and they have brown marks on em

Pull the plug wire from the coil to check the coil leave the wire close to the coil so it will still make contact get someone to crank it if it sparks its good next plug the coil to the wire then pull the wire off of the plug leave it close by so it will still make contact crank it again if it sparks the wire is good next unscrew the plug from the head connect it to the wire and crank get some one to crank it if it sparks then its good
