1991 Toyta Camry poors starting in cold weather

[fromthestars]

Hi,

I've owned a Toyota Camry 1991 4 cyl for almost 5 years. Hot or very cold, it would start on the first crank. I took it in for a major tune up to a reputable mechanic this past September. I noticed that as the weather turned colder it became harder to start. If the weather was about 40 degree F it would start immediately; if 20 degrees it would take around 3 cranks; if 10 degrees, about 8 cranks.

During the past week, the battery has been replaced, timing belt, thermostat, water pump; related seals have been replaced (all as part of normal preventative repairs). And yet, when the weather is very cold, it still takes multiple cranks to get it started. Before it starts, the cranks do not cause a partial start (sputter) until the one where it starts up, sputters a bit and then stays running.

Should I focus on anything where water can cause a problem in the fuel system when the temperature goes above freezing, the problem is minimal to non-existent. As it gets colder and colder, the problem worsens. Water freezes below 32 degrees and freezes more and more as the temperature drops and drops.

Does this make sense and what would you specifically focus in on? I'd appreciate your thoughts.

Thanks,

Nick

better check the coil on the distributor it's usually the cause for the car when it has a problem starting with moisture in the air.

Thanks for replying... but as I understand it the coil/distributer was replaced when the car had a major tune-up several months ago.

The 3SFE engines had a cold start injector and a cold star injector timing switch. Check the resistance at different temps on the timing switch and check the fuel flow on the injector itself.
