What should I do if my long crank wont start?
Just a recap of what you should do first to determine if your long crank before starting is fuel related or not. First, before you try cranking the engine over, turn the ignition key to the run position then back off without cranking the starter.
What should I do before cranking the engine over?
First, before you try cranking the engine over, turn the ignition key to the run position then back off without cranking the starter. What this will do is run the fuel pump and in most cases, you will be able to hear the fuel pump running. Do this 3 to 4 times before you try starting it.
Why does my car have a hard time starting?
As you know, a liquid cannot flow quickly if it is condensed. In that case, the engine has to push around a lot to spin and start because not much oil can get into the fuel line and the engine. You will need to change the oil filter regularly too if you do not want your car has a hard time starting.
What causes engine crank time to be extended?
Another common reason for extended crank time for engines is a vacuum leak. Engine vacuum must be a sealed system which the mass air flow and map sensors depend on to send feedback information to the main computer which in turn sets the stage for the engine starting sequence.

Why does my Car Crank for a long time?
When my oil gets to the end of its life i get the same thing. It cranks for a little longer to start. The oil gets really foamy and it take alot of oil pressure to run the injectors. I think the oil breaking down just takes more to pump the injectors.
What causes a Chevy pickup to hard start?
If after you have circled the key a few time the engine starts normally then you now know for sure you have a fuel pressure leak down problem causing your hard start. If this video was helpful please help support my youtube channel by subscribing here: https://www.youtube.com/channel/UChCX…

Why does it take so long to start a 300K engine?
Sure why not. On high mileage engines (200k to 300k) the pistons ring can wear causing low compression which increases crank time and causes hard starting. This is because the compression ratio is low and it takes time for the engine to gain enough speed cranking by the starter to ignite the fuel air mixture.

What causes a car to not start when cranking?
The glow plug circuit will not cause a no start. P0381 is a glow plug indicator lamp circuit code. P1670 indicates a possible fault in the EF (electronic feedback) circuit between the PCM and IDM, and is not a camshaft position sensor code. That code is often set after cranking with low battery voltage.

How many times does a Ford 7.3 start?
My 99.5 250 hp 7.3 has just started doing the long crank issue. Truck has always started on the second to third time the engine turns over. Now its 8 or 10 times before it starts. I went to the store and it started fine, went to leave store, and it was 8-10 times and has been that way for a week now.
What does it mean when your car cranks longer than normal?
The kit comes with 2 copper contacts and a plunger. It takes around 20 minute of work to replace. After the car is sitting for ~3 or more hours, it takes longer from cranking to starting. Does this mean the starter motor is running whenever you want it to, but sometimes it cranks for a longer time than usual before the engine starts?
What kind of truck won’t start after sitting?
Repair manuals and support for cars and trucks manufactured by Chevrolet, a division of General Motors. 2003 S10 V6. If the truck is started everyday it starts right up with no problems. If left sitting for at least 24 hours it is hard to start it.
Why does my car not start when I crank the engine?
If the engine doesn’t crank, or makes an unusual noise when cranking, you may have a starting system problem. The car’s security system may have made an error that disabled the fuel or ignition system, or the chip in the key may have failed.
What causes a car to have a hard start?
This guide will help by starting with simple fixes and conclude with the more difficult. What goes wrong? Normal wear and usage can cause a hard start condition due to lack of fuel pressure, poor intake air management, false readings to the car’s computer or weak spark.
Why is my Briggs and Stratton engine not starting?
But at starting speeds, it’s essential, otherwise the starter just can’t turn the engine over. If the engine will turn over easily and hiccups, won’t rev or make power, or just won’t start, then you may be looking at a fuel supply problem. This guide will help you diagnose and fix your hard-to-start Briggs & Stratton engine.
What should I do if my engine won’t start?
You should hear the pump start in the fuel tank for a brief period and then stop, cycle the key “OFF” then “ON” again without cranking the engine over while listening to the fuel pump, and do the cycle one more time to make three subsequent cycles.

Why is my engine hard to start or extended cranking?
So if the engine is warm or cold, this sponge has to be saturated and begin to drip before the engine will start and extended cranking is one of the classic symptoms. By trying the fuel additive and thinking of this as a diagnostic procedure, if your problem gets better, continue to use the fuel additive. No change, stop using the additive.
What causes a car to have a long crank time?
Many sensors report to the computer, who then takes that input and controls fuel or air delivery, is suspect when diagnosing long cranking times. A bad coolant sensor, a bad throttle position sensor (TPS), a bad fuel pump or a plugged fuel filter can all cause a lean condition causing long cranking times.
Is there a problem with the crank sensor?
First we changed the crank sensor, after about a day the problem came back. We then changed the cam sensor, its been about 2 wks. and haven’t had any crank issues since. Hopefully this helps somebody out there! Welcome to the forum Canpackfan97. When you have a chance, head over to the Newbie Section and say “Hi”.
When to run the fuel pump before cranking the engine?
Some systems will run the fuel pump for a short period when the drivers door is opened or when the key is turned to the ignition stop before being turned to crank. If this isn’t happening for some reason, you may be having to wait until the fuel pump provides enough pressure at the fuel rail to start the vehicle. My vote is for the injectors.
What should fuel pressure be on long crank?
NO MISFIRES AT PRESENT TIME TEST FUEL PRESSURE ON LONG CRANK. LET IT SIT FOR A LONG PERIOD OF TIME FUEL PRESSURE WOULD BOTTOM OUT AT 5 PSI AND TAKE AWHILE TO COME BACK UP. ONCE IT 5 PSI IT STARTD. RETURNLESS SYSTEM. FU 0 J REMOVE FUEL TANK AND DRAIN.
What causes engine to crank for long time before it starts?
When an engine cranks for a long time before it starts, either spark or fuel is missing or weak and each has its own reasons. Most of the time, the air / fuel mixture has been disturbed and there is too much air or not enough fuel.
When does the long crank start on a Cummins?
Long….. Long Crank when starting Long….. Long Crank when starting Location:Vancouver, WA. Need your help. I started having the long crank issue 2 months ago. I was still on the original batteries and had read somewhere that as they go they will still turn the engine over but not have enough to send the signal to the fuel system.

What causes a car engine to start cranking?
Normal service items: Prolonged cranking can be caused by a dirty throttle bore which can disrupt the airflow into the engine. The throttle actuator (throttle bore on older vehicle – cable) is an electronic throttle control which will get a condition called “coking” which is a kind of light tar like goo on the butterfly and its inner body.
