So i did this same thing but jumped the wires by cutting them and soldered them together and then plugged the connector back into the fuel pump ecu. My main ecu got fried, could this be because I plugged the connector back in instead of leaving it out like in this video? Thank you for any help, this car is making me pull my hair out
That’s super strange because I’ve heard of people plugging it back in and it didn’t do that. To be honest I’m not sure what could have happened but I think something else might have went wrong. Sorry for what happened to you and the lack of help :(
So, when you bypass the fuel pump module, the fuel pump runs at full whenever the ignition is turned on. Not a great situation if you crash and are unable to turn off the ignition. A disaster waiting to happen.
that ecu literally says A/T right on it if it was a manual ecu it would say M/T. i have a 93 factory auto swapped to a 5 speed and i swapped ecu over to a manual one and it says M/T, automatic one say A/T
Did u guys ever have issues when flooring it? Mine seems to have a slight stutter every minute or so at idle, it cranks for a long time before starting and when i floor it and the car downshifts it doesnt want to rev past 3k..
Sucks with preOBD2 cars to find little issues like this cause you can’t just scan them with a normal OBD2 scanner. This thankfully did fix it for us but it could honestly be so many things like a vacuum leak, sensors etc. I do believe there is a way to use a obd1 Toyota scanner to scan it if you can get access to that!
@@AimlessJP yeah its a pain the ass, but thing is with the issues we are both having its throwing no codes :( but what did u guys do to fix it? i have tried many option and i ran out if them so any input would be helpful!
We thought it didn’t because it stalled after we did the bypass when we turned the AC on but it never did it again so we think it’s actually fixed and he’s driven it for months now without it stalling. Might have just been that the ecu needed to relearn the first time after the bypass or maybe its because the battery was disconnected. Not sure but it did fix the issue :/
@@AimlessJP oh nice im glad he got his working good as new! welp thanks for the info, i planned on going back into troubleshooting this i will try and retrace some steps with how you guys troubleshooted as well. I appreciate the fast replies!
Mat is my favorite Aimless member
Same
You twinks made a good tutorial, gonna do this on my car
Oh word I got the same color sc 🥶
What is the suspension set up and the wheels?

Wire neutral saftey to a switch
He likes the fact that you can start it without pressing the clutch in even tho he doesn’t check to see if it’s in gear :)

When all you have is a auto harness and ecu , you bypass the Nuetral safety switch and you’re up and running

We didn’t have any of those issues :/
@AimlessJP hmm okay thanks for the reply. I can cross this off the list then
@CVBFonzp7B I am having the exact some problem please see this comment and let me know if you’ve resolved your issue
have the same issue with my 97 sc400, after doing the bypass, i still have the issue lol
