Hey all,
I've been wrenching on the FJ80 a bit doing some PM/chasing a hard start problem. The problem I have is when I crank the engine, it will turn for what seems like a long time(~5 seconds), and then when it turns over, it will sometimes act as if choked. Like you put carb cleaner in the intake. It will then rev up to normal idle rpm. I have not seen a pattern of when it stumbles.
I have changed out fuel pump, damper, regulator, fuel filter, cleaned injectors and cold start injector, ran some carb cleaner to clean the TB, checked and charged the battery, and all the normal maintenance items (minus a valve adjustment, kickdown cable adjust, and accelerator cable adjust). The truck runs great otherwise.
In my limited knowledge, have narrowed it down to 4 possible parts:

In my limited knowledge, have narrowed it down to 4 possible parts:
- Cold start injector (leaky or doesn't open)
- Cold start injector time switch (won't tell CSI to open)
- VSV
- Starter Motor (not enough power behind the crank)
