2000 s10 truck will not start in cold weather,new battery,coils,fuel pump and filter,crank sensor and heet product in gas tank,what more could i do ,WHAT IS THE PROBLEM

Not an unusual problem.....

Most important- tune-up! Make sure your plugs, distributor cap and rotor (if so equipped), air and fuel filter are OK and have been changed (at minimum) according to your owner's guide.

If your vehicle cranks over slow when cold-starting, consider a new battery. In cold weather, batteries lose efficiency, and older batteries lose more power than new ones.

Next... Gas - the fuel in cold weather states has a formula change in winter months to lower emissions- sometimes going to the next higher grade of fuel (example: from regular to mid-grade) helps.

If you have a garage, keeping the vehicle inside makes a huge difference with cold weather starting.

Keep your fuel tank full. Running the tank down and leaving it near empty most of the time allows condensation, which will result in getting water in your fuel, leading to hard starts and poor performance, and the increased risk of "rusting through" which will cause a leaky fuel tank.

Having the same problem with mine. Did you ever get yours figured out?

when engine is cold to requires more fuel and spark to start. coil or spark plug wires. fuel pump is still a possibility even though pressure is in range may not be just enough

Long cranking indicates a problem with part of the fuel pump assembly or the need for an air filter / tune-up. A restricted fuel filter also reduces fuel pressure to the injectors slowing cranking.

High mileage? Try a few bottles of Gum-out with a tank of gas, not the expensive stuff, just the regular fuel injector cleaner, then repeat & see if it improves. If it does, that would indicate Injectors and or fuel filter.

good luck

It might be coolant temperature sensor or O2 sensor.
Also check the grounding cables. Is it dead completely or crank no start. If it is not cranking it can be starter.
Also check fuel pressure (fuel pump, relay, fuel cut-off switch)
Please kindly let me know if you need more info
I am always here to help
Good Luck

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

Start with changing filter(fuel). Have you changed gas stations lately? Is it cold where you are. (gasline antifreeze or "Heet")

Try changing fuel filter first, if not replaced recently. What's the weather like in your area? Cold, maybe try some gasline antifreeze or "heet" in case of bad tank of gas?

Tune up... its flooding when its cold due to the plugs being worn out...
