if you have a US ecu then the hiss doesn't matter.

if the ecu isn't locked out by an external sensor then what's to stop it running? chances are you're missing something easy.

Iv found out that the us ecu requires a secon power feed on the white ecu connector iv power that with 12v and even tried 9 v still no start the fuel pump didn't prim iv checked and bypassed the bas sensor with still no luck any idea as to what I could be missing

you're missing something completely obvious then. don't spend a dime on something that's probably a 30 second fix.

when you key on do the FI lamp and HESD lamps come on for a few seconds then go out?

here's the imov wire you need to have

if the red black was dead nothing would come on. pretty sure the OP got past that




OP

start by checking the bank angle sensor fuse (fuse "b")

also check the FI fuse (fuse "g")


if the ECU isn't powering up it's either fuse b, fuse g, the kill switch, the bank angle sensor, or the engine stop relay. that's all there is in the circuit.


i know you said you checked the BAS, but did you verify 12v on the white/yellow? that's the wire that feeds the kill switch, bas, and ign coils. it starts on fuse "b"

Have not verified 12v on bas sensor as of yet I did bypass the kill switch to see if that was the problem

Your not gunna believe this wibbly and meatybeaty the yellow white wire had a very temperamental connection at the fuse box i was testing that wire cause it didn't have 12v like you suggested at the BAS connector end so i went back to the fuse box put my test light on the back of the connector all of a sudden the relays clicked fuel pump primed so i hit the starter and i fired staight up iv never heard this thing run and its beautiful cant thank you guys enough beers on me boys yous are ledgends smile ear to ear
