Why won't this bastard start?

2008 VDJ79 DTCs P062E and P062D, everything I test is OK WTF!?!?!

Oh what a feeling!

[@mikebarton]

What was the end result?

[@shooterjohn7508]

Check the green wire which is ground coming from the ecu

[@donne8694]

Checking continuity with ohms. Doesn’t mean good , it could go open under injector load , back probe the injector and check voltage under load , and also check voltage drop from Ecu pulse at injector make sure it is pulling negative to ground , because you swap the injector driver plugs and problem moves from half to other half , I’m thinking you have a input to driver missing or power dropping out under injector load ,

[@shooter5niper]

That's a good idea, I had considered just running new wires (white, pink, black, greena and blue) to the grey plug from the ecu but I didn't have enough evidence to convince me it would be worth it, I'll give that a crack when I get a minute

[@HustlerDrill]

I’m going to go completely off script and disregard the ‘sparkie’ diagnosis and play the ‘dropped valve’ scenario. Yeah, I know “put down the crack pipe.”

[@shooter5niper]

Ok, but how does a burnt or bent valve stop pulse getting to 2 injectors on one bank, 2 on the other, then switch cylinders when you swap the output plugs and follow the input plugs when they are swapped?

[@HustlerDrill]

Yeah, ya got me there. Didn’t think that through did I? The start up just sorta gave me the impression…had a C32 ‘fart and carry on’ like that…ended up being #5 dropped valve. I’ll go back and pull my head in…shall I? 😃

Needs a New engine computer

[@donne8694]

Also check for the input to injector driver module , what triggers it cam or crank sensor ,I’m not familiar with Toyota land cruisers maybe it has two cam sensor s and your loosing one of them causing no injector pulse on 50 % of them, do you have a rpm signal ,looking at data stream in your scanner .

[@shooter5niper]

RPM yes, I had this thought but I figured I would have lost one bank alone if I lost one cam signal
