additionally, the p0431 and p0421 are back after about 300mi since the rewiring and the CEL turning off. i was intending on starting a new post for those though.

note taken on the Kreen. i had read something of that sort on another forum about the stuff.

the red loom wires are right up to the ground strap at the base of the battery behind the firewall. i...

So, as of now which is 350mi from the following repairs:

- new ECM from Jack.
- new OXS's...

hahahaha. i love the acronym. i'm going to borrow that.

i got your email btw. :D

i'm waiting for the charger to finish trickling into the battery overnight. i've also gone back through wiring...

dually noted.

i've just checked timing and all marks line up as they should.

luckily, i'm pretty sure that i can isolate the EFI and ignition by removing fuses to ancillary components.

there's one missing at the moment, but D23 goes to the gn wire to the 87F at the FPR.

also, the FP relay gates the coils, correct? could also be an issue there for low spark V?

note taken on timing and jumpers to 15. how would one check the oil pressure regulation?

also, what about using ether to see if it fires?

ok. so with yet to use the brake clean and et al., i have just tested voltage from the T3 pin 15 to coil and get 10.5 when battery is 11.7 during crank. the spark from the plugs with coil removed is...

thank you for that. i'll get on it.

how might you suggest to get the Kreen out? just keep turning it over?

well, i guess the issue is now is that i'm not getting firing at all really. except from what is stopping rotation. although, i guess that would be the top limit of a misfire; if nothing is really...

Gotcha.

I don't think there is much carbon buildup, but I feel that you aren't meaning inside zyl?

I mean, I have done the volume test and I do have spark, but how much spark may be the...

i love that table. lol

i have identified all injectors to certainly be working fine now and the volume is ~160ml @ 30s.
i am still having the partial firing which stops the crank rotation, but i...

thats interesting. i had a high volume on my Benz once and then swapped the two pumps(yes there are two on the '87 300) and it normalized. wasn't up by that much though.

i meant that since the #1...

i can't see any oil on the plugs and i rolled up a paper towel nice and thin and put it down the plug hole on zyl 6 and didn't find oil. no oil on any of the plugs either. just fuel smell.

i also...

hey Jack,

i've been back at it this week and i have rewired all grounds from coils and POS's. i had to order a new Beru POS and a new Bosch FPR, which are installed and working.

First off, i...

So you're saying just to run new grounds from the stages in addition to the coils? I'm just clarifying

hey guys, (@jack)

i've rewired the grounds from the coil connectors with heavier 12ga wire to battery neg. I am currently testing the functionality of the power output stages and i need to access...

@ Jack.

i'm back working on it today. i have gone through the continuity for the coil looms and have not found any high resistances.

connectors to ground

#1 (br/bl) ...

certainly. i had mentioned the heat just because if twisted pair then i would use high heat capable auto wire instead of say coax, which might not handle heat as well.

so, you had suggested that...

@Jack,

Getting the money in order tonight.

Additionally, I've read the post from Kahlua, one thing, WOW!! lol. Don't bite the hand that feeds you. Geesh.

Do you recommend the twisted wire...
