'91 744 turbo. Last two days, it doesn't want to start in our 20 degree mornings. It sort-of catches, you can hear it fire every once in a while but not enough to get up and run. Once it starts, I rev it a few times, it clears it's throat and runs perfectly. After about five start attempts this morning, I disconnected the AMM and it very reluctantly started. I reconnected the AMM and it set an engine code which I haven't checked yet. It starts fine in 45 degree afternoons after being parked eight hours. The tank was pretty low last two days but is full now so I'll see what happens tomorrow. Had to resolder the OD relay recently and am going to pull the fuel pump.. oops MFI... relay next and resolder it.

Any ideas? is there a cold start injector on LH2.4? Am I barking up the right trees here?
