What causes engine crank time to be extended?

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.

What causes a GMC truck to turn over but not start?

If the engine starts up normally after doing that, it means that fuel pressure is bleeding off and the fuel pump needs to prime the lines before it can start. It can bleed off from one of two places. 1. Fuel pressure regulator has an internal leak, and fuel is bleeding off back to the tank though the return line. 2.

What to do when your car engine is hard starting?

A visual inspection of all vacuum lines inside the engine bay you may discover a broken, torn or dilapidated hose that needs replacing and for harder to find leak a smoke tester can be used or when the engine is cold a can of carburetor cleaner which will cause the engine to idle normal or speed up for a brief period.

How often does my GMC Truck turn over?

So far this has been the case pretty much every time i am starting the truck cold. I’ll try to start it and it will turn over for about 3-4 seconds (have tried a bit longer, still no go) then i’ll stop and try to start it again, and the second time it fires right up.

What to do when your GMC Truck won’t start?

Try turning your key to the run position a few times (with out starting). Then try to start it. If it starts, sounds like what mine did. I replaced the fuel pump assembly and that fixed the problems. Very common problem.

Is there a way to reset the index of Git?

Alas, sometimes it takes us a bit longer to realize that we are on the wrong track, and by that time one or more changes may already have been committed locally. This is when git reset comes in handy: Be careful with the –hard option! It resets your working tree as well as the index, so all your modifications will be lost for good.

What’s the best way to fix a Git problem?

Git Tutorial: 10 Common Git Problems and How to Fix Them 1. Discard local file modifications. Sometimes the best way to get a feel for a problem is diving in and playing around… 2. Undo local commits. Alas, sometimes it takes us a bit longer to realize that we are on the wrong track, and by

How to avoid common mistakes with git hooks?

Avoid common mistakes with git hooks Some mistakes happen repeatedly, but would be easy to avoid by running certain checks or cleanup tasks at a defined stage of the git workflow. This is exactly the scenario that hooks were designed for. To create a new hook, add an executable file to .git/hooks.

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.

Why is my car cranking but not starting?

Your vehicle may still start with your battery as low as 50% but at that level, it may also leave you stranded on a cold day. If you’re having other starting problems, we’d like to help out with that too! Why is My Car Cranking but not Starting? If your engine will turn over but just won’t start you could have a few different problems.

Why are Hall effect crank sensors more troublesome?

Hall effect crank position sensors are more troublesome because they’re vulnerable to electrical problems in the wiring and internal circuit components. Hall effect crank sensors typically have three wires: voltage supply, ground and signal return. They produce a digital on-off signal rather than a sine wave AC signal like a magnetic sensor.

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.

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.

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.

What to do if your truck starts and runs then dies?

If the problem isn’t your body control module , fuel pump, injectors, nor ignition switch. Flip over engine compartment fuse block carefully and check for bright green coloring around wire port. If any color is present use an 8mm or 10mm socket and loosen the bolt holding the wire connectors on the bottom of fuse block.

Why is my GM 3.1L engine not cranking?

A no crank condition means that the engine is not cranking when you turn the key to crank the engine. This is usually due to a bad starter motor, bad ignition switch, bad neutral safety switch, or maybe the engine threw a rod and is locked up.

What causes a cranks but not start condition?

PASS-Key/Passlock system failures are a very, very common cause of no start conditions. As you can see, quite a few things, when they fail, can cause a cranks but does not start condition.

What happens if the crankshaft on a Duramax goes bad?

Perhaps the most devastating of all Duramax failures is a broken factory crankshaft. Not only does this mean game-over for the engine, but it results in a truck that’s down for weeks (if not months) and a huge chunk of change missing from your wallet.

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.

How to prevent fuel from draining back into the tank?

After sealing the pump (made a paper gasket and this stopped the leak) it still takes a long time to build up fuel pressure. I have a new fuel pump with a large bowl (automatic with air type) and the fuel filter is quite large (clear plastic type ~2 inches in diameter).

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.

One, your engine is having trouble producing a spark. Two, your engine is having difficulty obtaining fuel. Three, your engine is creating compression. What is so pivotal about these three components is that to successfully run and drive the vehicle the engine needs fuel, compression, and a spark all working simultaneously.

When do you know something is wrong with your exhaust?

To do this, you need to be able to notice when things are going wrong with your car’s exhaust (such as unusual exhaust noise or exhaust blowing) and how to fix it.
