FJ40 I call Shipwreck

[DanStokes]

I know the feeling! Added 6 feet to the width of my driveway so I can back trailers out. Few days after fixing it, school super's wife backed a brand new Blazer in the ditch.. I never shifted an auto transfer case before, she wanted me to unhook trailer and pull her out. Naaah. Switch in 4by and jumps out.."My husband will never know, will he?". Nope lady, unless you tell him. Garbage truck turned around in neighbor's driveway. Wider than mine, MISSED IT! Took 2 huge wreckers to pull him out... I laughed too hard!

Two words: "situational awareness".

Did FiTech tell you what they fixed?

[Beagle]

and then what? you'd rather I not post my adventures? seriously, stop trolling.

not trolling - I'm trying to help. Your problem seems to be transient, moves around.. computer junk usually dies immediately or lasts for a long time. It seems like something is changing in your environment because things work, then don't work, then work. Like I said, no worries, I'm just throwing ideas out for thought. It wouldn't be any effort on my part to stop.

Hope they find the issue, and get it back to you quickly.

I contacted Holley recently with a very simple question. What size are the factory jets in my Quick Fuel 650 double pumper as they go out the door. Of course I could pull the bowls easily to find out, but wanted to know before pulling the bowls. It only took them a week to finally tell me they're 71 primary, and 74 secondary. Way to big for my 350 SBC.
I emailed back to tell them their response time was horrible, and I'd already gotten tired of waiting and pulled the metering blocks to see for myself.

[Beagle]

the sarcastic in me suggests the only reason it was running was because of the rpm noise issue. I fixed that issue, then it stopped running.
and I'll say it again, even more directly, there is not a grounding issue. something within the computer was unhappy and it stopped triggering the injectors....

I'll just quote that for posterity in case it happens again. I own Nike stock, no worries.

[Beagle]

ground loop interference, low voltage, low current devices... it doesn't take a whole lot of noise to get a bad signal. Just throwing it out there for consideration.

go back a couple years to where I'm ranting about Dakota Digital and their grounding demands (that you cannot use the frame as the ground) and which didn't f ix the problem....the grounds have redundant grounds

So, the Holley folks were adamant that you run a dedicated ground from the battery to the ECU. I too have a ton of grounds (3 power train to frame and 2 body to frame) but got tired of arguing with them so I added the one they wanted. They also were quite clear about wire routing to minimize "noise". Seems "clean" power and grounds are important to EFI systems.

[Beagle]

do you ground the efi sensors back to the efi controller or use chassis/battery ground?

[silver_bullet]

Wow

‘90’s TBI in general does a good job of proving how simple it can be to make an engine run. I’ll never forget the first time I saw fuel spraying the top of a closed butterfly valve.

FGZ.. that needle/seat spring CAN and DOES fall off.. Have had it happen..

[fatguyzinc]

guaranty I'd die on that 35% plus hill that I took a picture of... since when is an electric pump not mechanical?

the spring loaded needle and seat set works WONDERS for
an off road application. ask me how i know...

as for hating EFI, i hate EVERYTHING computer controlled.
if theres any job in the world with built in job security, its IT tech.

i like carbs and mechanical fans and mechanical pumps and
such because they have rarely left me stranded--but EVERY
electric fan, holley blue or red pump, aftermarket efi, etc has
done it to me and lots of other people i know of.

[STINEY]

Wow. Good thing they already have the big name. They would never build a new name with any intangible value with that attitude towards customers.

[1946Austin]

Sounds typical. Instead of answering questions promptly, they instead make excuses. And instead of doing a little research, or reading up a little, they ask questions they already have the answers for. So sad that companies seem to hold good customer service in such low regard, and use covid 19 as an excuse for providing poor service response time.

You're right about the EFI and how it's shown on TV to be just a plug and play affair. I didn't even know that any systems beyond the really high end systems had tuning ability? Thought you had to spend over $2500 to get a tuneable system you could tune with your laptop.
