More than likely the choke is sticking, spray some WD40 on the carb components and see if that helps.

1998 olds silhouette hard to start in cold weather


I suspect your car doesn't have a choke if it is EFI.

I'd suspect a faulty coolant temp sensor unit, which is not telling the ECU that the engine is cold.

Some EFI cars have an extra injector called a cold start injector. If fitted this could be faulty.

In both the above cases there may be an ECU trouble code you can read out. In the US Autozone will do this for you.

In the old days the classic cause of hard starting was always faulty engine timing. If your car has a timing belt and it is worn, it may have jumped a tooth or 2., but this is uncommon.

A practical alternative to replacing parts at random would be to take your vehicle in for a comprehensive diagnosis to identify the real cause of the problem(s).

I have a 1987 ranger 2.3 EFI and sometimes it will not start when it's cold. after it warms up outside it starts. When it does start it runs great. It always starts when warm. some times it will


Timing belt being off one tooth will not cause this problem but rather loss of power and hard starting all the time,

in the cold it will not start, the engine will spin but wont fire is this correct?

There are many things that can cause this, a little testing will be needed, the first thing that comes to mind with the ford and cold weather is the coolant temp sensor, it give computer a false reading and can cause hard starting or even no start, a scan tool would be helpful to see what temp it is give computer.
The best way to narrow this down to to check for spark when it wont start, a weak coil in cold weather will cause this problem or bad coil wire to cap, but if you can see if it has spark and let me know,
another test is to check fuel pressure, to see if it is getting fuel, and the fuelpump relay,

Let me know if it has spark or fuel when is does not start, good day

1998 Ford Ranger 4 cylinder will not start when cold, I put gas on the air cleaner and it starts. What is wrong


This is a problem caused by a defective fuel pressure check valve at the outlet of the electric fuel pump inside the gas tank. When this valve fails it allows gas to drain back to the tank from the filter and fuel lines, this creates a lean fuel condition and that can cause hard starting. There are reasons but this is the most common one.

My 1991 toyota 4runner keeps blowing the efi fuse and my engine floods gas. what could be the problem?


Check the EFI main relay, the circuit opening relay, and the fuel pump relay. Inside the fuel pump relay there is a switch controlled by a coil. During start, the fuel pump gets full power for a couple of seconds to build up pressure. Once pressure is good, the fuel pump relay is supposed to switch (via the coil) the fuel pump to reduced power. If the coil in the relay is bad, the reduced power setting is not available and the fuel pump will run at full power all the time. At this heavy current draw, it won't be long until the EFI fuse blows. This would also give more pressure than is necessary to the cold start fuel injector which runs on a timer. This extra pressure during the time that the cold start injector is operating may be the reason the engine is flooding with fuel.

Heater in truck blows either cold air or no air.


It sounds like you have air trapped in the cooling system. Try filling the radiator and coolant reservoir cold. Then leave the radiator cap loose and run engine at 1500 rpm until it warms up and the thermostat opens. Make sure heater is on full warm setting.
