Why does my Harley hard start when warm?

When the engine is warm it is tighter and requires more from the starter which in turn needs more amperage from the battery. If your hard start is slow cranking when warm I would have checked this first,then checked starter draw,then fuel and ignition.

Are there any problems with the 8.1L Vortec engine?

Common across most Vortec engines, the 8.1L also suffers from common intake manifold gasket failure. Most of the gaskets weren’t designed perfectly, but gaskets are also simply wear and tear items. Over time, gaskets go bad, just so happens the the intake manifold ones go bad a little more frequently than others.

Why does my ttora not start when hot?

If I start it when cold or not up to operating temp it fires right away. I’m just thinking that the coolant is leaking back from the hot head to the coolant temp sensor, heat soaking it and causing it to run a rich start up. I’ve checked the sensor and all the resistances seem to be within spec.

Why is my Chevy 8.1 L engine not working?

The electronic throttle control in the Chevy 8.1-L V8 engine can lose the signal between the accelerator pedal and throttle body. The throttle control normally sends a signal from the gas pedal and into the throttle body, telling it how much power is required. Once this signal is interrupted, the throttle body does not work correctly.

What makes a 1995 Camry not to start when hot?

Forgot to mention that, the Camry is 1995, unlike modern ignition coils one for each cylinder; it has a central distributor and delivers high voltage to four spark plugs through a set of wires. Thanks. I have a feeling that your crank position sensor (or camshaft position sensor in some cars) is faulty.

Why is my Chevelle 350 hard to start?

Fuel pump check valve doesn’t maintain pressure in the fuel rail so it boils and then you have to crank excessively to get rid of the vapor before it will start. Bought a 1972 Chevelle 350 a couple years ago. Every time I drove it it wouldn’t restart easily or sometimes not at all unless I waited a while.

Why is my car engine hard to start?

The starter itself may not be cranking correctly due to the heat impacting the relays which drive the mechanisms (this was a common issue in old air cooled VWs, and with how some newer engines are crammed into engine bays similar things can happen).

Why does my Chevy tracker not start up?

No “check engine” light. Starter would crank normally, but no start. Since the car has a vibration at freeway speeds I checked those relays that I could find ( not quite sure why so many relays when a switch would do). No go. Tried again, started right up and ran the 1000 miles to home. Now a year later same problem. Did the relay game again.

What kind of engine does a Chevy tracker have?

Where are the relays on a Chevy tracker?

With manual in hand I located another flock of relays cleverly located high up on the left kick panel above the cabin fuse panel (there’s more fuses in the engine compartment). Shook, removed/replaced ALL. No go. Jumpered the fuel pump relay (sub’d a wire for the make/break contacts). No go. Cussed.

Why does my Chevy tracker spit and sputter?

My 1999 Tracker just started doing this a couple of weeks ago once outdoor temperatures started hitting the 90s (F). It only does it sporadically, though. I’ve also left it idling in park and it’s died a few times and then it does the ‘spit and sputter’ ordeal again trying to get it started.

Why are fuel injected engines hard to start?

This way, fuel injected engines would not become so easily obstruded by vapors as other engines would and therefore the car would not have the same problems to start as another would. Also, engines might become hard to start while being hot if it coincides with the season in which refiners change from one fuel blend to another.

Why is my riding mower hard to start when hot?

Higher temperatures create higher resistance to the flow of voltage, that’s why coils usually fail when the mowers hot, and starts working again when the engine cools. The enemy of electrical systems is moisture, so a mower should always be kept indoors in a ventilated area. These are the tools that make mower maintenance and repair easy!

What does it mean when Your starter says heat soak?

What exactly is starter “Heat Soak”? Without getting into the physics of thermal conduction or Newton’s law of convective cooling, it is simply a matter of the starter absorbing and retaining heat from under-hood sources such as the exhaust manifold. This absorbed heat adds resistance to the electrical conductors inside the starter.

What happens when you heat up a starter?

Once under-hood heat warms the battery, cables, and starter, a “tipping point” is reached concerning the overall amount of resistance a starter can accept (and still function properly).

Why does my Car start when it is warm but not cold?

Why does my bike start cold or hot?

On cold starts, the engine usually fires right up, but after reaching operating temperatures or when on the hot side, I occasionally have a hard time getting the bike to start. The dealer has already replaced the starter, because it sounded like a thrashing machine.

Which is harder a cold start or a warm start?

As Hillsons said, cold starts are hard. So are warm starts, but to a lesser degree. The engine has no oil pressure when off, and starting it again causes very slight but very bad metal on metal contact. When warm this is much less contact than when cold, as the oil is usually primed and circulated.

Why does my truck shut down when it gets hot?

Same exact problem on my 95 f-150 4.9L. Runs great first start but after 2 miles or if very hot outside, it heaves and misses and eventually shuts down. Starts after sitting for 45 minutes again. I did replace rotor, cap wires plugs and coolant temp sensor as well as the starter. No fix.

What happens when you discontinue power to the starter?

When you start the engine and release the key the circuit will, discontinue the power to the starting motor.

Why does my starter motor not work when it’s Hot?

his idea is that the starter motor won’t work when it’s hot because the old grease doesn’t provide enough lubrication when the starter motor is heated up by the engine and all the metal expands that little bit – but that it will work when it’s cold.

What’s the difference between a cold and hot starter?

If you didn’t have a starter solenoid you would need a huge ignition switch to safely & reliably complete the high amp circuit. On the second question, the fundamental rule is resistance increases with temperature. A hot starter will have far greater resistance than a cold one, as will a hot starter lead & starter solenoid.

What are the symptoms of high resistance in starter motor?

The symptom of high resistance in a starter motor or lead is it will turn slowly or not at all. The symptom of high resistance in a starter solenoid or its associated wiring is the solenoid fails to engage therefore the starter fails to spin.
