Restating 2000 odyssey after warmed up


not sure what that means.
lets start over.
your saying car runs great, cold then hot.
then hard to restart a hot engine, right?
the light thing i dont understand
first off, when you stall and engine or just key ON.
the lamps all self test (read the operators guide there)
this is only a lamp test.
odd, the most important is skipped the CEL, check engine light.
is the engine stalling?
hot restarts, fails are: many.
  1. injector leaking at shut down.
  2. ECT reads to cold when hot. can be below caused
  3. Engine thermostat stuck open and restarts are over rich and floods. that hot engine must be at 180F or more,
  4. never did a 60,000 mile tuneup this decade?
  5. Fuel pressure too high.
i do tune ups first.
then check coolant temperatures, hot. 180F min, and holding or i kick the thermostat to the curb (new stat time)
if it sill dont want to hot start
out comes the scan tool
i scan it, got DTC errors.
is ECT reading 180F ? or above?

that is start on diagnosis.

Hot Starting Problem


hard starting problems when engine hot could be restricted air filter.restricted clogged fuel injectors.engine could either be diesel or gasoline.if engine dont start and starter wont turn over engine. could have bad battery ground cable or battery positive cable could have broken place when cable get hot crack increases cause less current engine wont have enough power to turn over.

I have a 2000 Jetta 4 cylinder, 2.0 engine. It starts fine when it has not been started but once the engine gets hot and car is completely turned off it won't start. It sounds like it wants to start but...


Hi.. I had a very similar problem recoverrd to are workshop by the A.A around a month ago.
Exactly the same problem (left to cool started.? Once worm or hot engine just turning over ?)
Afdter reading all known folts and finding nothing to do with what I'd wanted. It took some time ?
Cutting it sort if found when I replaced a intermittent faulty fuel relay and run till engine hot (untill cooling fan cut in) Then turned off engine .. on turning key to see if this had cured my problem?
The engine started frist turn of key after repeating this a number of times .. this car was now starting fine (whether hot or cold)
Problem fixed..
Hopefully this will be of some help to yourselves

Will not start on hot day's in the sun.[engine cranks normal]


The normal reason why a hot engine doesn't start is the choke. Your fancy new range rover will have a computer controlled choke that will be activiated by a temperature sensor. maybe this has failed or is disconnected
In my ancient range rover I have a manual choke but essentially the same engine. I know that if the motor is hot I can't start it with the choke on.
The way the choke works is it restricts the airflow into the engine so that there is a richer fuel / air mixture which is needed for a cold start. If the engine is hot and the choke comes on the engiine floods with petrol and there isn't enough oxygen for it too ignite in the cylinders. To start a flooded engine you have to open the choke and crank the motor without pressing the accelerator. This pumps out the petrol vapour and eventually it will fire and start. If the computer thinks it is cold because of a disconnected or faulty sensor it will put on the choke whenever you try and start and the engine will flood.
I think a vapour lock is unlikely unless you driving in extremely hot weather (above 40 degrees celsius).
