Tim.smith: According to pictures of spark plugs, i was expecting totally wet ones.
I mean, wet without resistors and dry with resistors (if it's the case, we can conclude something).
did you notice any diference with and without resistors?
I can't still conclude wheter is lack or to much fuel
okay so let me make this clear the plugs i took pictures of were the plugs that came out of the car when it first came into my shop.

I don't think cam crank is an issue because there are no codes, there's injector and spark control, and my initial suspicion concerning the missing injector ramps after all of them fire, well, if the cam crank was an issue the missing ramps would be consistent throughout the capture, not just on initial crank, so that leads me away from cam issue.

I've think it's time we have a look at your cam and crank signals. When you have outputs that are not being turned on, like fuel injectors, it's probably due to bad inputs. Just look at the missing ramps !
You second question about the signals jumping around. That looks like a scope sample rate issue, if you had peak detect turned on you wouldn't see that. Long time bases cause this issue
Don't be a parts changer!

I hate to disagree with Paul here, but I think this is actually a scope ground issue. :blush: :lol: Ignition coil trigger signals (and other signal circuits) look like this when the test lead is connected to the coil, but the scope ground either isn't connected or connected poorly.
That doesn't stop the amp probe from reading correctly, however, as it doesn't need an external ground. It makes it's own voltage, and doesn't need to be grounded to the car to work. That's why the amp trace looks OK, but the trigger doesn't.
For example, I got this off my car. Green trace is connected to the #3 coil, but no scope ground is connected.

I then decided to unplug the fuel pump and see if I could make the car only run on carb cleaner only with no fuel pump it did and quite well once I got the mixture right.

How about a balance test? but all injectors at the same time?
cheers.
This ^
The ramps look fine now at ~1 amp each
