My first post here. I bought my 93 SC400 in August 07 for 1,500.00. The owner told me they wiped out with it and hit a curb. Looked more like a median with some light rear quarter damage. When I got the car on a lift I seen that all of the drivers side rear suspension had to be replaced. Being a mechanic, I bought the axle, strut, upper control arm, spindle and everything else associated with the rear for 300.00. The car has 186,000 miles on it and runs beautiful. The only otherthing i had to do was replace a weak battery and it been great to me ever since. I do have a slight problem though, after the car sits for a couple hours, i will go out and start it. It runs for about 3 seconds then shuts off. I have to pull the key out, put it back in and try it again. Because if i try to start it with the key still in the ignition it wont fire at all, i have to keep taking the key in and out inorder to start it......after about 5-10 mins of doing this it fires up and runs perfect...im still trying to figure this one out. Other than that its been a smooth, reliable ride...not bad for 1800.00......I finally have my 2 favorite cars i have always wanted...The SC400 and my 95 300zxTT.

I just bought my 94 sc400 and i had the same problem, what had happened was whoever had the car before myself, put regular fuel instead of premium in it, so they had to flush out the fuel injectors, replace them, and fill em up with premium and let it run for a second, after that was finished, its run smoothly ever since, might want to check it out and see

This is a comon problem wiht the sc400 its your fuel ECU located on the driversice rear panel "Under the rear side window" There is a paperclip method (jumper 2 points in the engine compartment diagnostic port) to test this there should be a post sowhere in here with more details... but I can say with a 99% confidence the FUEL ECU is the problem..
