N cold weather hard to start

I had a new fuel pump put on my Dodge Pickup and a week later it stalled . I checked the injectors to see if they were getting fuel and it shot gas out like it had fuel but the pump they put on was defective it was pumping fuel but not enough to start it .
I would take a spray bottle and gas in it . Unhook your air filter and then squirt fuel into the intake . If it starts for a second you will then no within a shadow of a doubt that the fuel pump is not pumping enough fuel.
Also check to see if your in line fuel filter is clogged . I don't know what part of the country you are in but a cold climate can cause a dirty gas filter to gel and not allow enough fuel to get past.

change plug wires fuel filter and cap and rotor if ur ccar has one

this is most likely a fuel vapor issue.

fuel boils in the fuel rail causing a hard start after a 'hot soak'.

the fix is to replace the fuel pressure regulator and the pcm. good- day !!

with many new modern fuel injected vehicles its hard to give them a tune up without plugging them into a computer or getting an aftermarket computer chip and programmer.

however, if your toyota is running a little rough and getting bad gas mileage i would reccomend a new set of spark plugs and wires. and maybe a new fuel filter, i would do the spark plugs first, if the results are not satisfactory then change the spark plug wires, and if the results are still not up to your standards comparing the way it used to run to how it runs now then change the fuel filter. doing all these things will make the vehicle run clean and efficient like it should. and if it doesnt than im sure you have a vacum or oxygen sensor problem.

just wanna hop up the performance a little bit and get better fuel mileage?
then i would suggest and personally recommend a complete K&N cold air intake kit.

check your air filter and your fuel filter when you start it dont push the gas down its injected. A block heater can help. It might have one there is a plug near the front bumper inside if it has one. Try running some fuel injection cleaner through it. I like Techron Make sure you check your air filter and clean the screen in your mass air flow sensor with the special aerosol spray

Have you the vehicle tuned up lately? Bad spark plugs will cause hard starting in cold weather also, the fuel filter could be plugged or it may have moisture in it. I guess, I would have those items checked and also, have the fuel pressure checked, the pump may be getting weak.

Turning is good, but does it have spark? How do you know fuel pump is good? whats your fuel pressure? Spark plugs? I know these may have a problem in cold weather, Put a little oil in each cylinder, new spark plugs and hold the gas pedal to the floor and see if it starts. Make sure you have a good battery.

check your main relay it may be in default it is the signal that sends the gas pump is located below the driver side dash give me the new

The correct spark plugs are very important. Glad to hear you got it fixed good.

Check the condition of the wiring coming off of the ECM. at the fender. I've seen the wiring insulation rub off causing no starts.
