Running on 2 cyl. lsvtec
like the title states, i recently did some work to a friends lsvtec and now im having some issues.
i changed the spark plugs.
i unclipped the injector plugs to tuck some wire out of the way
the car ran fine before all the work.
so the problem is im getting spark on all four connections where the wires go on the dizzy, because i see the spark arcing to the wire.
but only the num 3, and 4 pistons are firing. 1, 2 nothing.
when the car is on and i remove the first two wires there is no change in the engine.
and when there was spark on all 4 i could see an arc from the wire jumping inside the spark tubes.
i will also be testing my first two injectors tomorrow. but any help will work thanks.

Re: Running on 2 cyl. lsvtec
update: there is energy running to all four injectors, so fueling is not a problem
this is where im stumped, there is spark at all four plugs but only 3 and 4 actually ignite when the spark plug is in the combustion chamber. the only way i can get num 1, and 2 is to have them out on the valve cover. but once in the chamber i get nothing.
i swapped the spark plugs on 3 and 4 to 1 and 2 but it didnt change a thing.
both of my grounds are good.
no check eng light.
could it be the spark plugs on 1 and 2 arent grounded?

Re: Running on 2 cyl. lsvtec
Got to agree with mafia.
What do you mean exactly when you say, "there is energy running to all four injectors"
Do you mean there is power, [12V+] at the injector plugs, [wire that is the same color at all 4 injectors]?
If so, have you checked to see if the injectors are getting a ground pulse from the ECU/ECM? 94

Re: Running on 2 cyl. lsvtec
well no matter to any of this, i guess everything was functioning as it should of been. pulled the num 1 spark plug and wow.
the piston smashed it pretty good.
it wasnt a clearance issue but i guess now it was.
;(
the guy who built the engine did a horrible job. oil was already leaking out of the headgasket on to the side of the tranny.
im sure the piston was the main problem having no compression
