Depends on vehicle.First check the air filter to see if it is wet.If it gets wet,it will not let air through the filter and flood the engine. you most likely got the ignition component wet allow to dry for a day or so you should also check the condition of the spark plugs wiring
you will have to buy a new motor they are only 7 pound same happened to mine
Check for sparkCheck for fuel
Put gas in it.
Yeah, because you drove it into a river, flooded the engine most likely, fired the electrics...and basically destroyed the car. Good going.
Dead battery, out of fuel, failed starter, failed computer, failed fuel pump, etc.
Check the trans fluid for water, if you have water you have major problems.
I have the same problem, it has happened twice on my 2003 Discovery. Towed it to the dealership and they cannot find any fault, it started just fine for them, it is with them right now for 2 days, cannot figure out the problem.
Possibly the firing order got messed up.
Call the person who repaired the car and tell them what is going on. But what you write above makes no sense. You say, "(wont turn over) (wants to start) by (wont stay running)" If it won't turn over, how does it want to start, and how can it be running in the first place? Did they replace the fuel filter. If not, they should have.
the the cover off of your distrubutor cap.. look and see if the screw is in the post of the spinning disc.. or see if it turns freely.. 3 dollar fix if so..
clutch gone try putting into gear then start engine be ready to shut engine off
