Question about Honda Odyssey

1 Answer

Odyssey cranks and runs fine until ot gets hot, then it shuts off and will not crack again. Then, after the car sits and cools down for a few hours, it starts again at the first try.

Car cranks in the morning just fine, then it will run for about 20 mins and will not crank again until cold.

Sounds like a fuel pump with the information you have given me. An Independent garage will be a lot cheaper and more reliable than the Stealership. Good luck

    I think the coil or ignition module is most likely. Replace module first as it is most likely of all.

Ignition module is the likeliest place to look.

SOURCE: 95 saturn won't start when hot

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

I had the same problem. Turns out,( and I didn't believe it when I was told) but, my problem turned out to be cheap (inferiour) plugs and wired. I was reccomended to use NKG plugs and Borg-Warner wires.

SOURCE: 2006 f250 diesel....crank and crank

The first thought that comes to mind is a high pressure oil leak. The injectors have a snap ring on top that sometimes becomes detached and it will create these symptoms.

When you depress the brake it sends a signal to the PCM (Powertrain Control Module) and the PCM increases the idle because it predicts you are about to shift into gear. If the truck has a high pressure leak inside the engine it will have a hard time building pressure initially and once the oil warms and thins out the High Pressure Oil Pump cannot hold the pressure and the oil leaks faster because it is thinner.

You may have a leak around the pump area which is under the turbo also. The IPR which is the regulator that controls the oil pressure may also be bad. It is directly under the turbo as well. The IPR is located under the turbo on the High Pressure Oil Pump cover. You stated the seals were leaking on the IPR itself? If the orings are damaged or if the screen in the end of it is collapsed or even punched through with a small hole it will need replaced. Screen damage is usually a sign of debris entering it from either dirt from a previous repair or something is coming apart inside.

Make certain you have clean oil and fuel filters. Yor may want to check fuel pressure as well. It should be somewhere around 55psi on acceleration.

Additionally, I suggest check for voltage at the connector on the fuel pump. The pump is mounted in the filter housing on the frame and the connector is at the front of it. The pink and black wire should have 12 volts with the key on for about 30 seconds. If the pump has voltage but is not running, then your pump has failed. If there is no voltage then check fuse 2.40 in the central junction box. This is the fuse that feeds the inertia switch through the fuel pump relay. I have included a fuse box layout and a wiring diagram (click over images for zoom)...

Additionally, will need to scanned the PCM to know if some fault code is stored there.

Does it crank over when the engine is hot. If it does sounds like your maybe loosing fuel if so check fuel pressure if t is good check for spark could be a bad crank sensor or bad distributor.

Runs great but sometimes after a hour starts missing and shuts off.


Not positive but sounds like coil pack. There is a liquid coolant in em and if it gets a crack in it then it over heats easy. So after it gets hot it stops working. Then it cools back down and works right. Just basing this on other cars I have worked on. Some have two wires per coil. When it starts running bad pull one of the wires off and seee if it runs the same or worse. And if it is the coil you should be able to trace down the one that is bad. Just trying to help.

1998 Hyundia Tiburon would stop after engine got hot and after cool down would start and run fine. Now after it has been sitting for awhile(7 months) it will not start! (it crankes over good) no gas or no...


It's a sensor. I had one that was cracked. When the car warmed up the heat caused the crack to expand and the sensor wouldn't work. After the car cooled it was fine until it got hot again. The sensor is probably gone for good now. You would need diagnostics or troubleshooting to determine which one. You can get a hand held diagnostic computer for cars. Some auto parts stores check for free. You could see if any does a loan-a-tool.

I have 97 camaro it starts and drive fine but when i shut it off it wont start back up until it sits for a few hours?


We had a problem like this in our 97 Camaro with the V6. It would run fine until my wife went somewhere with it, parked it and then wouldn't restart. When it would sit for about an hour then it would start again. It turned out to be the crank position sensor, when the electronic part of it got hot enough it couldn't sense correctly and tell the computer how to time the spark. All it would do is crank without firing. So once we had that sensor replaced it ran good again. Good luck I hope this helps! I'm on to the next problem it's having, an occasional battery drain and a radio and electric windows that die when they want to and come back later. BuzzieTN

Check the wiring. to Coil, plugs, Crank Positioning Sensor. check to see if the wire is in good condition sometimes if wire is checked, in poor condition it will allow bleed through especially when the wires get hot. This is why it will often start when engine cools down and why it shuts off when your sitting cause it heats the wires up there is not the cool air running accross the wires when sitting. Good Luck and a grt day. Would appreciat 4 thumbs up if this was helpful.

I had the same problem a few years ago. The problem was a cracked coil. The unit would expand and separate when the car got hot and it took a while to cool off and reconnect.

2000 caravan 3.0 stall after 20 min no spark restarts few hours later


This sounds like a bad (probably cracked) ignition coil.

First, the coil gets hot when operating, and this is normal.

If it is cracked, it gets hot to the point where its resistance gets so much higher that it cannot provide enough voltage for spark.

When it cools back down it starts working fine again.
