Hard to get started when cold no back fireing you have to hold it to the floor and let up and repet it has spark and gas


Check fuel pressure at the schrader value. Pressure should be 41-47 psi with Key-ON, Engine-OFF, and hold (within several pounds). If it drops rapidly, the cause is most often the check ball in the fuel pump. This is one of the common causes for hard starting.

Holding the accelerator to the floor during starting puts the PCM into the "Clear Flood Mode", if this is your issue.

Starts fine cold then starts and shuts off then starts very hard but will start . could this be fuel pressure regulator what what happens to make for lean air fuel mix during cold start in 80's had a cold...


The computer runs the fuel mixture rich when cold and then leans out as it warms up into closed loop, a common problem is the regulator leaking, if you remove the upper part of the intake and then turn key on and watch for fuel leaks, another trick is to remove the throtlebody and use a light to see if fuel is puddling up on the top of the intake, make sure to dissconnect module connectors to avoid a false start or spark that will cause a fire, i would almost bet its the regulator, hope this helps,

My 99 yukon wont start when its cold, I can spray carb cleaner in the throttle body and it will fire,but other wise it wont start unless its warm.


When is the last time you had a tune-up on your truck? During the cold winter months, if the battery does not have a proper level of cranking amps it is sometimes hard for the engine to turnover in the cold. You may need a tune-up or battery replaced.

5.7 Hemi won't start in cold weather.


Cold weather makes the engine hard to start for two main reasons. First, oil thickens when it's cold, which increases friction and makes it harder for the starter motor to spin the engine. Cold also slows the chemical reaction in the car's battery, reducing its power output. Battery output is usually rated at 77°F, below which starting power drops drastically.

You can ensure that your car will start in the worst weather by keeping the engine or the battery, or both, warm.

You may want to consider a trickle charger for the battery to keep the chemical reaction working and an engine block heater to make it easier for the pistons to move freely.

Hard starts in the morning even though replaced most parts


Check the power to the cold start injector. (it's only going to have fire for a few sec. after the key is turned on). If the fire is good, replace the cold start injector. This injector is activated for a few seconds when the engen temp is low to add a little fuel lower down in the intake and closer to the pistons.

1992 F-350 Dsl - very hard to start when cool


are you using cold temperature engine oil!
if not, try changing oil for cold temperature!

hard starting happens due to the cold temperature, air pressure is low during this season so compression inside the engine is low resulting to hard starting!

make sure that all your glow plugs are working.
