Ls400 hard cold starts
Hi, I have a 1992 Toyota Celsior (Lexus ls400) and its having a hard time cold starting. When its warmed up it fires right up on first or second crank. After sitting over night it cranks for about 30-45 seconds until it try's to fire up. The car runs fantastic when its started and only has 40k miles on it. I'm not sure what to begin checking in this, I'm hoping someone else has experience. The battery cranks the motor very fast so I know it's not that. I'm thinking possibly cold start injector? Maf? I honestly don't know where to start. Any help would be greatly appreciated! Also no check engine lights or anything.

Problem solved, same as the tach problem. Soldered in new capacitors in the Ecu and the car fires right up now.
