Will my car not start if I need a tune up?
2. Difficulty starting the engine. Difficulty starting the engine could be a sign of a number of problems, all of which can be prevented (or at least identified) by a proactive tune-up. For example, it could be that your spark plugs are misfiring and preventing your engine from turning over.
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.
Do you need to override cold start tuning?
Depending on which wideband controller you’re using, it may not operate until it detects engine RPM or won’t operate during cranking. This is obviously at odds with our cold start tuning requirements so you will need to override this if that is the case.
Can You tune the VE at 0 rpm?
1. It’s not strictly possible to tune the VE accurately at 0 rpm as obviously we can’t hold the engine here. It’s a balancing act between the VE value in these cells and the cranking enrichment value as well. The ECU uses both and we could effect the startup by altering either.
What to look for when your engine won’t start?
Check for a blown fuse that may be preventing a circuit from working properly, like the fuel injection or computer system. To operate efficiently, an internal combustion gasoline engine needs a good spark, the right amount of fuel, and good compression (a healthy mechanical condition).
When do you crank the engine to start?
When cranking the engine to start, the ECU only uses the Cranking Parameters (in Ignition Parameters). The “Cranking Timing” is usually set to 15°, and the “Crank to Run RPM” is usually set to 400 RPM. This means anytime the engine is below 400 RPM, the ECU only com mands 15° of ignition timing.
What should the crank to run rpm be?
The Crank To Run RPM is not the actual cranking speed of the starter motor! When cranking the engine to start, the ECU only uses the Cranking Parameters (in Ignition Parameters). The “Cranking Timing” is usually set to 15°, and the “Crank to Run RPM” is usually set to 400 RPM.
What happens to the ECU when cranking an engine?
One engine may require fuel enrichment during cranking and startupto last for a long time while the next engine may need it to last less time. Only trial and error will tell. Once the start cycles are over, the ECU reverts to the engine temp values to supply a richer mixture as the engine warms up. These are also programmable.

How many people own a Toyota Avalon car?
Toyota’s flagship full-size sedan, the Avalon, is so comfortable, reliable, and affordable that it’s owned and driven by over 1.3 million Americans. Like everyone else, Avalon owners face a few obstacles associated with owning a car.
When does a Toyota Avalon airbag failure occur?
Airbag Control Module Failure (2003-2004 models only): When an airbag control module failure occurs prematurely, the front airbags, side airbags, and/or seatbelt pre-tensioners deploy unexpectedly.
How long does it take for a Toyota Avalon to start?
After few more tries, and about 15 to 25 minutes, the engine finally would crank slowly and finally got started. At that time, everything seem normal again, except that all the settings for the LCD display (time, date.etc.) and the audio system all went to the original default and need to be setup again.
