It could be a few things that always happen on these cars:
fuel pump - check if gas is getting to engine
ignition coils - check if either of the 3 or all are bad( each 1 lasts
long so you don't have to go changing them all)
ignition control module (piece that the coils are on) - check if it works (how I don't know but mechanics do)
vacuum lines - all those rubber and plastic tube lines must not have any cracks or holes (i had to replace 3 rubber parts from the dealer because car kept shutting off)
if ur car is also losing power on uphills or at turns it most likely be ur fuel pump. Bad fuel pump will act up more when there is very little gas too (low voltage, loss of power)
Good luck

I have a 01 toyota celica runs and starts fine but once you ride it for about 10-20 mile it will wants to shut down while riding I try to keep it going but most of the time it will die .. Then it doesn't...


This usually happens when the crank or the cam sensor starts to go bad. The crank sensor will get hot and shut the spark off to the plugs. When it cools it will start up again untill it is completely no good. I would replace the crank sensor.

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.


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

Runs fine until it gets warm or hot then cuts off then cools and will recrank


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.

My 2002 jeep liberty starts and after a period of running and driving and when shut off and immediatly try to start again it will not till its cooled down does anyone have any idea


Its a hot start issue.
Can be related to low fuel pressure or problem with crank sensor.

Also it can be weak battery or starter.

But possibilities are to be inspected to confirm what exactly it is.------
