How long do you have to crank the engine before the engine starts?
On two separate occasions in the last couple of months, I had to crank the engine for a long time (30 seconds or more) before the engine would start. After each of these occasions, it began starting normally again until my recent problem.
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.
How long does it take a Ford PowerStroke to start?
About a week ago, my truck started taking a long time to start while cranking. So far, it has started every time. However, it takes anywhere from 10 to 30 seconds to start. It used to start after a couple of seconds. If I turn off the ignition and start it again, it doesn’t seem to take as long to start, but still longer than usual.
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.
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.

Why does my car make a long crank when starting?
The reason for this is that the fuel viscosity is lower when the engine is warm also the clearances in the engine (injectors, CP3) are bigger causing more leakage. The CP3 needs to make 3000 psi in the rail before the computer will fire the injectors for a start. The case that is being described here is backwards from most cases I have seen.
