pin 7 code 11 after ETA rewire

[larsen]

I bought a 1995 e420 (CA model) cheap knowing it needed a wiring harness and eta. i was able to drive it home in limp mode and i even got it to drive a bit without going in limp mode. I rewired the upper engine wiring harness and trottle body. After installing everything the car no longer goes into limp mode but it it undrivable, the fuel shuts off at what seems to be random when pressing on the accelerator pedal. I consitantly am getting pin 7 code 11 Fuel safety shut-off signal to LH-SFI control module (N3/1). While very confident in the engine harness rewire on the eta there was a light green and teal wire I had a very hard time differentiating from one another in their aged state. Would an improperly wired eta cause these symptons? does anyone have wiring diagram for the eta or upper engine harness?

Another concern of mine is after reading and clearing the codes on pin 19 it no longer gives me any blinks. All other pins will give me 1 blink for no codes, is this ok?

How can I use the led blink reader that comes on CA models that is located forward of the computer module box?

After checking this video https://youtu.be/NldqBgud2ws I can see that S1 which is supposed to be open at idle and shorted when the throttle opens (between pin 8 and 10 on the eta connector) stays open even when the thottle is open. Looks like I failed to rewire the eta properly, pin 6 and 10 were swapped.

I am still curious about the 8 pin CA diagnostic connector and why my dm (pin 19) fails to blink.

Waiting for a reply myself, good question!

Pin 19 (DM) may fail to blink if there are zero codes, this is normal, especially if the CEL is off. There's a mention of this buried somewhere in the factory manuals, IIRC...

I put the car into limp mode and pin 19 happily blinked a code. When I cleared it no blinks. I guess its all good. Got the eta put back together and the car runs and drives without going into limp mode. It still runs quite poorly so I decided to pull off the right side distributor, worse ive ever seen, cracked and corroded.

Good T/A (trial and error) but pictures or it didn't happen !

Help! I'm still getting Pin 7 code 11 fuel safety shut-off signal to LH-SFI control module (n3/1). It is doing this at very light throttle when warmed up. It Wil rev and cut out an bounce between 1000-2000 rpm with the trotted maintained at about 10%. I'm going to warm it up and retest my eta according to that video.

What conditions will cause a fuel shut off signal to be sent to the lh module? I'm aware if any of the switches in the eta and the switch on the accelerator pedal do not function properly it will do this, are there any other senarios? I should ad it idles well when cold at around 500 rpm and poorly closer to 1000 when warmed up. Ordered distributors already, I know they are cracked and corroded.

I don't know the answer to your question... but are there codes on any of the other 5 primary modules (LH, EZL, BM, ABS/ASR, DM)? More specifically, any codes which come back quickly after clearing, same pin 7 code 11?

Also, does your car have ASR or not? Pin 7 code 11 can also mean "Closed throttle recognition signal to LH-SFI control module" for non-ASR.

Car has asr. Pin 6 code 2 is a hard code, will not delete. Front left vss open. I can pretty consistantly get it to throw pin 7 code 11 even when cold now. It is at a very specific trottle position leading me to believe it still has something to do with the idle and throttle switch in the eta. Uploading a video of the symptoms tonight. I'll update if it throws any other codes, it's only been driven a couple of short cycles.

Here is a video. Car does this consistantly at the same throttle position in all conditions. It is very annoying since It starts right at my prefered throttle position for accelerating, a little before and I'm barely moving and pressing down to get past it im accelerating a little more aggresivly that I prefer (best mpg).
