ATX LSX

Did a coil relocation, extended coil harness.

First issue was driver's side wouldn't fire due to INJ1 fuse being blown (passenger side fired at the time). Fixed that, now passenger side isn't firing.

None of the cylinders on passenger side are firing, manifold is entirely cold.

Checked wiring, it's good. Fuses are good.

WTFBBQ...

Anyone have any suggestions?

wiring isn't good LOL

Did you check voltage and see if you have any faults?

if it wasn't good, then why would they have been firing when INJ1 fuse was blown?

May i make a suggestion and suggest you make sure the grounds are all in place. My buddy's had the same issue when he redone all of his ****. Turned out he had a bad ground connection. Might be different for you but worth a shot

i would start with, Does the pink wire have ignition voltage on the coils?

ATX LSX

No I haven't... not an electrical engineer but I know how to extend a harness.

all Im saying is if the car ran fine before the coil relocate, the only thing touched is wiring... orr what else did you touch?

I'm not an electrical engineer either, but my point is, trace back the path of signal so see where it is that the break is. So if you're not getting spark at the plug, go back to the coil, check so see if the coil is getting a signal to fire. If not, go back to the harness for the 4 coils and check there.

Well..the results might indicate otherwise, and fuses rarely blow when wiring integrity is good.

So do you have 12v at the pink wire ?

How are you confirming you have a no spark scenario ? and is it all 4 coils on one side, or some coils ?

And are you sure all 4 are firing on the other side ?
