it seems to be fine now , i may have another issue with #5 , but atm its running great, with the 3rd replacement ecu. Only thing i notice is it has a light gray mist when cold , but after its warmed up its all good

i will probably do just that. im assuming the drivers were bad in the old computer , as it hydrolocked the engine but with the new engine it runs fine , i wonder if it was a combination of the two both stuck #5 and an ecu . maybe thats why the engine runs a little rich when cold

So i wanted to give an update on the engine flooding issue. I received a new used ecu and cleaned out all my cylinder of fuel. i cleaned the spark plugs and reinstalled them. I noticed that the #5 cylinder was full of fuel when i took out the plugs. All the plugs were black and wet with fuel...

do the injector grounds pulse when they fire?

So update on engine issues. the new ecu didnt change much, i still idles right , but it still has smoke coming out that smells like fuel. i havnt tried driving it to see if this is just residual fuel or what . Injectors maybe? . #6 cylinder was flooded when i pulled all the plugs out. it was the...

im guessing the injectors stay on all the times when the output is grounded?

nvm i just watched your youtube video, test seems similar to swapping around ignition coils for leading and trailing misfires

ive already sent out the " suspect bad ecu" but just for my own knowledge, how do u test to see if the drivers are bad?

have you seen issues with injectors over fueling due to ecu issues ?

i dont have the rear 02 sensors wired , but the front ones appear to work fine. I Don't suspect o2s to blame . it didn't affect the drivability prior to the 1st computer. i replaced the old computer due to it losing m-rel power out. Im more concerned the engine hydrolocked when i was trying to...

SO i have a 88 cressida with a 95 ls400 engine swapped I had to recently replace my Ecu with a used one , due to having a power output issues on my m-rel on the original ecu. now i have major issues after the computer swap!!!! The first day i installed the new ecu it idled really low but...

fair enough.. guess im getting a ecu

so this is a common trait of the ls400 ecus to happen?

Ok.... so updates. the aftermarket relay didnt work, but i got me thinking.. So the m-relay only comes on when there is a constant power supply (which it has) , and a switched power from out the ecu that is turned on with the ignition to the run position, and a ground (which it has). I checked...

im going to install a aftermarket relay tonight so fingers crossed . im still confident there is a short somewhere . its just hard to find
