I think most likely it got mixed up, that would be an easy fix if that is the case.
Def the first thing you should check, I am off friday maybe I can come and help you diagnose some more. I remember we used the other cam wire for the ground for one of them, it should have been for the cam ground if we did it for the crank ground then we got the grounds switched 100%

This was no crankwalk because it started to happen again on the new short block ,it from the 12V fuel pump mod is distroyING my crank pulley,flywheel and crank gear when you remove the key out of the ignition there is a delay the car will stay running and as soon as you insert the key in the ignition it will start pumping and spraying fuel and fill the cylinders with gasoline , so when you try to start it it will lock up it sound like the starter was hanging on the FW.

So you wired the ecu back in? What is controlling the hi/low inputs, the aem?

Yes i installed the ECU back in there, and i guess it's being control by the AEM.
My friend Slow_SC3 is running the same setup and he doesn't have the 12V mods on his SC and he is making some serious power, so i know i will be fine.

How is you car coming along?

Slowly. Was out of town all this weekend but I have 4 day weekend coming up and all my parts are in. I hope to have it in and running this weekend. Seeing your latest fuel system woes, I think I will run sans 12v mod and see how it goes. Are you running a denso or walbro or something else?

If you have a 300 you can do and you won't have any issues, i did it on my SC300 and i've never had any issues with it.
I think it's the way the SC400 is Set up from the factory.
I got the 044 inline and Walboro in tank but the walboro will be coming out and the 044 will be in the tank.
300 and 400 have alot of differences bro we always think they are the same lol.

Yeah, must be. I was looking at the wiring diagrams and saw no noticeable difference in the fuel pump circuits between the two, but depending on year, etc, we know there can be discrepancies that are not noted.

It is a curious issue though. I almost wish I could look at a car that was doing it so I could put a probe on it and see where the stray voltage was coming from...

I assume you could hear the pump running when you took the key out? Or was it just barely getting voltage to where it was too quiet?

it will run, mine runs for about 5 seconds after pulling the key with the 12v mod, but the injectors don't normally do any injecting cause the ecu knows its shutting down. maybe its a sc400 thing, still have no idea why quickgs's car was doing that.
If his runs fine i will probably put my fuel ecu back in later as mine works fine.

Hmmmm. I'm actually considering just running a dedicated feed on a relay and skipping the stock circuit completely. With my Aristo ECU, I am not sure what the trigger voltages are, so I may have to figure something out with that.

Sorry guys for the late replies , i was on vacation for the last 10 days.

I got the Car Tuned, last Tuesday it been running great better than ever, I had AliSC3 tune my idle so i told the tuner not to touch my idle.
We street tune it up to 20lbs and it will break loose till 3rd gear.
The only downside on this setup is the "Lag" it's a little laggy compare to my Old setup.
I went from 1.3mm HG to 2.0mm and there is a big difference.
I was pushing 24lbs on the last setup on high C.R that's how i had BHG lol and on this setup 20lbs on 9.2 CR so it's definitely slower than before.

The Fuel Pump EcU was installed and no more cylinder fuel of gasoline.

just FYI:
you shouldn't be going over 15psi on 9.2:1 compression on 93 octane gasoline.

really ? well with 9.2.1 cr I ran 19 psi and made great power with no issues.
lexforlife made 600 rwhp on the same setup, mine was never dyno tuned it was 2hrs street tune.
I had 9.8 cr and made ridiculous power at 17 lbs... so it can be done and when I was getting to do my setup no one believe that I could make 600rwhp on 93 oct on the ge with TT hg with the right EMS, right setup, right tuner it can be done and has been done.

I blew my hg because my MBC was garbage.
