New opti still #3 wont fire

New wires and plugs, what the hell will cause this same cylinder not to fire? Its just this one, all the other header tubes are hot and this is the only cold and i pulled another plug and it was dry, #3 is still soaked with gas?

Re: New opti still #3 wont fire

is the wire to #3 good?
swap plugs, or put a new in #3

check fuel pressure, if it bleeds down after you shut the car off, pull the rail loose from the intake and turn the key on, see if #3 inj. is spraying fuel


check compression, pull #1, 3, and 5 and check them one at a time, they should be close, post back with the results

Re: New opti still #3 wont fire

i noticed when i tap the gas to rev it idling, the rpms drop a little then rev up like its hesatating but then it does it, im going to run it down the street and see how it acts.

Took it down the street and it was kinda hesatating, it would give it a little gas and it would make like a poping sound im not for sure, im going to check all my wires and make sure there all the way on the opti.
