no codes im guessing

test your crank and both cam position sensors just a guess.

what did the plugs smell like, do a compression check

no codes ur right ill update that...


ill check the sensors in the am....

what bout a craping out ecu?? "whats a car do when the ecu is bout to take dump?"

ill check compression tomorrow, cause i need to, but i know thats not the problem right now.. plugs were wet, my nose is clogged up so idk on the smell

the ecu was going to be my next step. or atleast 1 of the next steps.

[JDMGRNAV6]

anymore opinions?

Put fresh fuel in it and check the old stuff for water after you pump it out. Put a fuel gauge on the fuel rail to see what the pressure is at the injectors. If you have good fuel pressure use a noid light at the injector or a analog volt meter to see if the ecu is firing the injector correctly. If there is no injector firing then you have a cam or crank or ecu or wiring problem. Next check the cam and crank signal. You will need a scope to do this. If the cam and crank are scoping out correctly then you need to look at the ecu or the ignition coil. Scope the cam and crank close to make sure the wiring is good. You can also check the resistance across the cam and crank sensor (distributor) and wiring instead of using a scope. If your cam and crank sensor are working right then check your coil for a trigger source with your analog volt meter. If its not getting any signal then its your ecu or wiring in between. Try a new ecu and If the coil has a trigger source then check for spark at the coil not each spark plug wire. That should get you fixed up.

that pretty much sumed it all up...ill work from there thanks

you figure it out?

yeah pm me your questions


and honestly if i hooked my ecu in another sc400, and the ecu was bad, would it do the same thing in that car? and could i use that test to rule out a bad ecu?

[D3UC3S]

He broke it towing it.....:doh:

[JDMGRNAV6]

the tow guy broke it, not me bish, i pulled up and it had already happened.

[D3UC3S]

Take it easy lady....:kiss:

Try searching on club lex. That is how i figure out whats wrong with my sc3. Welcome to the Lex fam :goodjob:.

[RallyMazda01]

hmmm. my sc4 did the same thing after the 4.7 bottom swap. somehow the ecu went bad. a lot of the sc4 have that problem. so i just went and got another ecu and was fine. btw u should go check out clublexus. Lots of good ppl there that know a lot about this stuff. they helped me out. and yes. welcome to the lex family.:goodjob::goodjob:

[JDMGRNAV6]

thanks guys for the help...

and yes club lex is a great help as well

[JDMGRNAV6]

Car is officially running..

The fix was a new ecu

thanks you guys for all your help
