First off all, thanks Marc for your help earlier, you figure with what we came up with it would have fixed it... Here goes... 88 GTS, 3SGE... Will not start in cool/cold weather. I crank it over till the battery dies... nothing Go out when it is warmer in the afternoon, starts right up. Replaced the cold start injector, cold start time switch (brown plug sensor), and EFI temp switch (green plug sensor), both known working spares. Checked for bad wires, checked grounds (all I know of and can see) Changed fuel filter/air filter back to standard paper, removed K&N Checked timing MAF seems to be working, or else it wouldn't run at all. Higher octane gas, mid grade. Fluids up to level and spec. Am I missing something ????
