2007 Toyota Tacoma v6. Hard to start about 1 hour after initial cold start, longer cranking. Problem?

1. Cold weather: Cold temperatures can affect the performance of the engine and make it harder to start.
2. Battery issue: A weak or failing battery can cause the engine to take longer to start.
3. Starter issue: If the starter is worn or damaged, it may struggle to crank the engine, especially in cold weather.
4. Ignition system problem: If there's an issue with the ignition system, such as a faulty spark plug or ignition coil, it can cause the engine to crank for a long time before starting.
5. Viper DS4+ installation issue: The Viper DS4+ remote start system may not have been installed correctly, or it may have a defect that's causing the issue.

Could you give more detail as to what it's doing exactly? Is it having a hard time cranking the engine or does the engine crank but not want to get started?

93 mirage doesnt have a choke, it is fuel injected! What exactly do you mean by hard to start? Does it take longer than normal to start, does it initially crank slower than normal? You could try cycling the key before attempting to start it! By this i mean, thrn the key to RUN, wait a couple seconds, turn key to off, turn back to run, wait a couple seconds,, turn to off, then attempt to start! See what that does!

indicates an ambient air temp sensor or BARO sensor problem
run the fault codes
the ECM tunes the engine every 60 seconds from reports for sensors so the old fashioned tune up is not longer cost effective
better to have the fault codes read on a regular basis
an occasional can of quality injector cleaner in the tank is a good investment

how about the fuel filter. I didn't see this on your list and it should be done every 20000km and the air filter. I think its a fuel filter. not the pump. could be the coils but I would start cheap and change fuel filter first. when the pump is cold it pumps with more psi to blow passed the clooged filter after warm it is weaker and has a hard time pushing through the clog

MAKE SURE YOU ARE USING THE CORRECT OIL WEIGHT. SOME WEIGHT CHANGES IN COLDER WEATHER IT WILL BE IN YOUR OWNERS MANUAL.2ND BATERYS TEND TO HAVE A 3 YEAR LIFE DO A LOAD TEST ON BATTERY AND I THINK YOU WILL FIND YOUR PROBLEM

Yes,need to make sure crank is at TDC as well

run the fault codes
look for a problem crank/cam position sensor

no.. u need to have a dealer do it.. they also have a tool ti check it the remote is transmitting a signal as well

Try cycling the key to just on, then off, on, off, 2 or 3 times & see if that helps with start? (priming fuel system) to see if maybe pump is getting weak or possibly filter plugged.
