[FIXED] 2001 ACURA CL 3.2 CRANKS/ NO START
Each injector has it's own ground wire to the PCM so you can't scope them all there if you're trying to get injector current ramp. For injector current ramp you need to go to common power feed. But you already captured current ramp so I'm confused.tim.smith1 wrote: how would i scope all the injectors at once off the ground wire?
If you're referring to the injector balance test, that entails installing a fuel gauge on the rail, energizing the fuel pump to pressurize the rail, and individually energizing each injector to check for flow. The balance part means ideally you want each injector to spray and drop psi on the rail, equally, in a set period of time.
If you don't have that tool to pulse injectors, you can energize each injector by grounding each injector control wire manually as right now we're just concerned about flow.

My mistake. When i mentioned "all injectors at the same time" i was saying is so weird to have all injectors failing at the same time. I was imagining an stuck open injector adding to much fuel on cylinders. Anyway, i think a balance test is necessary at this point.

Another tests you can perform. 1. Take out the complete fuel rail, turn on the fuel pump and look for any injector leaking. 2. Taking care of any spark and with injectors firing in the air, crank engine and look for any stuck open injector (I have seen some injectors which only get stuck open when you turn it on).

I suggest you to take this Bad gas and test it and compare it with good one. It's a great chance.
If you have time/lucky, let us know.
Cheers.

I'd like to see that gas if you have a picture. I have two rules for gasoline:
1) You must be able to see through it. It can be yellow, orange or a little brown but if you can see clearly through it after it has been poured, it should combust. (Just because you can light it with a lighter doesn't mean it will run an engine)
2) can't smell like varnish, turpentine or anything that turns your stomach.
I ran strictly junk yard gasoline in my last two trucks over the past 10 years and never had an issue following those two rules.
I've also seen many people break down taking liberties with those rules
We don't have E85 so I've never encountered an alcohol content issue but that can be checked for easily with a clear container and small amount of water.
