Runnin on 3 cyl. help

[SRK420a]

Ok so my car is currently running on 3 cyl. 1996 Eagle Talon. I changed the plugs and wires because i thought it wasn't geting spark but when i cut it on Its still the same i pull the wire of cyl. 1 to see if its getting spark and it is but the cyl is not getting it every other cylinder is pumping fine what could be the problem .....bearing.....piston...blownheadgasket...any help is apreeciated and repped.:thinking:

if its not spiting out water than it's not a blown head gasket since the cylinder isn't firing.
ONE Question...... have you check the injector wiring? on older cars, the injector wire can wear out and break off, so the injector isn't getting signal to let gas into the cylinder.
bad bearing or piston wont keep the cylinder from firing.

Its rainin so i cant tell wen it stops i will take a better look but so far from the view i had the wire looked fine my friend says i need to do a compresssion check because he says i could have an f'd up piston or ring

[jcs]

also take and switch a injector and see if the problem will switch from that cylinder to the one you put it on if so you know its a bad injector....still nothin then get a comp test and see if its low on that one.then its possibly a bad ring ect

[ballistic08]

definatly do a compression check.

[Theycall_Metue]

even with a f'd up ring, it'll still fire

Could it be a bad piston or ring?

[EmminoDaGreat]

Yes it can be a bad piston.

I would look for, burnt or bent valve, melted/broken piston.

Ring Lands Break all the time is the car boosted
