1997 Toyota Corolla Long crank with cold engine normal start and operation after warm engine

Very long cranking time causing too much fuel in cylinders and copious smoking by the time it does crank, check engine light comes on after extended cranking reporting misfires on all cylinders, once engine is warm and the ecu is reset there are no error codes. Battery, starter, alternator test good, new plugs, distributor cap, rotor, Intake Air Control valve cleaned and replaced along with throttle body, new fuel filter, fuel pump operational, all fuses are good, once cranked I have to rev engine until normal idling occurs and then after the engine is warm it cranks and runs normally and no error codes are produced. Ran Injector cleaner through the tank, How do I logically diagnose the problem?

Hi, i would like to advice you check the electronic idle speed control valve and also check engine coolant temp sensor. The ISC (idle speed control valve) is located somewhere below the throttle valve. the engine coolant temp sensor is located near distributor. it has a two wire connection. the sensor connector is usually green

Good Evening, you might want to check those injectors, I can not remember for certain but that setup was sequential and when one or two have a problem it would take out the rest. Ohm out the injectors and see what you have there.

SOURCE: Engine won't start.

Sounds like your fuel injecters are plugged. Wouldn't do you any good to add fuel injecter cleaner to your gas if engine won't run, so you would need to remove your injectors and clean or replace them. Hope this helps: http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?displayName=Fuel+Injector&currentPage=1&categoryDisplayName=Fuel+Delivery&navValue=14900120&itemId=prod61264&parentId=cat30060

1997 Toyota Avalon. Problem: Mornings, won't start until repeated cranking warms engine a bit, then holds idle well (without pedal assistance) and starts and runs flawlessly all day.

Fuel pressure regulator may not be working properly, allowing fuel pressure to bleed off overnight. Try (before going to crank position on key) turning the key on for 3 - 5 seconds, then back off. Do this three or four times. (The fuel pump will run for 3 - 5 seconds before the ECM turns it off if you don't go to the start position.) This should allow pressure to build to what is needed initially to start the engine. Now try to start normally. If this works, you need a new pressure regulator. It is located either in the fuel rail, or on the fuel pump itself.

Engine died while driving on the freeway, now only cranks but wont turn over/

As with any no start problem, have you checked for spark at the plugs and normal fuel pressure at the injectors ?
Does it crank with normal compression ?

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

Is the check engine light on? How long has it been since the engine was tuned up? A worn plug that is "hot soaked" can create a longer cranking time. Hot soaked means it may have some un-burned fuel in the cylinder since the first cold start. A weak or worn plug has a harder time getting this fuel burned out of the cylinder when more fuel is being added during a warm start.

Ok I have a toyota corolla AE91 ... It starts it runs for 20 minutes or so then it stalls. The engine cranks but does not fully start. It only restarts when the car has cooled down. My mechanic changed the...

One possibility is that the engine coolant temperature sensor is faulty and is stuck in full cold mode. Lots of fuel is scheduled for cold starts, however, as the engine warms up, it needs less fuel. Too much fuel when warm and the engine floods out or riches out. The engine coolant temp sensor is telling the computer that the engine is ALWAYS cold even when it is warm. So, too much fuel is being sent once the engine is warm.

I have a 97 corolla, when I first start it in the morning it starts fairly easy, but when it warms up and im running errands around town, it cranks longer before it wants to restart, and its getting worse,...

The engine coolant temperature sensor could be stuck in the cold mode. This would activate the cold start injector even with the engine warm--and flood the engine with too much fuel, making for long crank times. The engine coolant temperature sensor (ECT) is usually located close to the thermostat housing. It has two wires coming from it. The coolant temperature sender for the dash gauge is not the same. It only has one wire and grounds through the engine block. It is easy to get them confused.

My toyota corolla is always hard to start whenever it is cold day?how can i fix it?

Yourr car have 4 cylinders, there are 4 injectors and 1 cold start injector. You can trace it from your Fuel distributor. Your cold start is operated by a electric valve. It has a normal close state and only open when you start the engine. Its function to inject extra fuel so you can have a rich mixture for easy start. Now it is dead so you don't have a fast start. Have it replaced then you will be happy.

2003 toyota avensis diesal . dificult starting from initial start

I am assuming this a cold weather only issue ?? Turn your key to on before cranking it over for about 5 sec to let the glow plug heat up a moment. Not allowing the glow plug to warm will wear out your starter.

97 caravan has a long cranking time before it starts?

the most common cause of this is a defective fuel pump check valve, if this valve is not working the fuel drains back to the tank and each time u start it the fuel must be pumped all the way to the injectors, then the air must bleed out, this causes long crank times and stalls after starting, the problem gets worse with cold temps of winter.
