Hello everybody, I'm new but I promise I'm not a "hi-bye"! I just bought a 92 sc300 and 5 miles down the road the dash lit up. Check engine, oil temp and oil pressure lights. There's tons of white smoke (it's not the head gasket, no coolant loss and good compression) and it smells like raw gas. Tons of gas in my oil. I trailed it home. It's not the valve stem seals, there is no oil loss either. 200k on the clock, but it feels like it would run great if it wasn't DUMPING fuel. I'm almost positive it's the ECM. It has water damage, and the FPR has no fuel in the vacuum line, so the diaphram is ok. I'm really just asking to confirm my thoughts, to see if anyone else has had a similar problem or if somebody has an ECM they could sell me. My part number is 89661-24310. Auto with traction control. 1992. I've been told the're NOT interchangable, but I've read 92-94 are if they have identical options. (california, auto, traction control) Thanks for any advice, I do appreciate taking the time to respond. I'd like to drive the old girl, my 5-spd 944 kinda sucks in morning traffic! -cale Minneapolis

Hello fellas! Just bought myself a half-decent SC300. 1992, Champagne, tan interior, cheap chrome wheels and a fuel delivery problem I found out about 5 miles down the road after I bought it. It's DUMPING fuel, the oil fills with gas after a few days, smokes like crazy and smells of raw, unburnt fuel so it's undriveable a this point. The check engine light came on along with the oil pressure and oil temp lights. I towed it back. Hopefully not too much damage was done. I bought some 10-30 royal purple, does anybody recommend some sort of additive? Lucas? Prolong? Slick 50? There is no coolant loss, so it's not the head gasket. It could also be the notorius valve stem seals, but there is no way to tell until I fix this fuel problem first. I've read the computer is the likely problem because the regulator vacuum hose is dry and the pump is feeding plenty of fuel. I've also been told the only way I can replace the computer is if it's the exact same part number. Does anybody have any suggestions or similar problems OR parts? I'm pretty sure it's the computer, there was some water damage and was not repairable. (Yep, I tried to repair it.) I'd really appreciate any help, suggestions or clues to fixing this fuel issue. If there are any checks or diagnostic tricks you guys know of I'm up for those as well. Thanks! Cale A. MN
