My car won't start but everything else comes on
My 2003 Honda odyssey was running untill I turn it off to
put gas in it then when I went to turn it back on it would not
start but my lights horn and radio still works what could be
It could be a bunch of different things, i had a customer bring their car in for an oil change and it pulled in the bay just fine and my guys pulled it out just fine but when my customer went to leave it would not start. after looking at it i found that the Fuel pump had gone out. when you turn your key on check to see if you can here the fuel pump turn on, if its not making any noise then tap on the gas tank. you can also check the fuel pressure but hooking up a gauge on the fuel rail.
1. If this happens just after adding gas, it's a failing EVAP system component. Could be a vacuum leak or a defective purge valve. Could also be the result of overfilling where gasoline flows into the EVAP line. 2. If this also happens elsewhere, it could be a failing fuel pump. when fuel in the tank runs low, it's no longer cooled by the fuel. When you attempt to restart a hot pump with cool fuel, it can cause internals to not function correctly; it's like cavitation. 3. Did you check the battery? Maybe it's just dead.
