Why does it stay on?

[Jonsey]

so today was the coldest day of the month, thus saying winter has come.a brisk 32*F.the car is in the garage as usual.i turn the key and and the fuel pump prime noise comes from the back as usual, but now, it stays on after i turn the key off.This happened last year when it got cold and it would turn off after like 10-15 minutes after i turned the car off it also turns off like that now.Im just wondering, whats the problem?i changed the starter solenoid a few months ago.Is it going to wear out something or drain my battery?

[mrltd]

sounds like the fuel pump relay is sticking

[Jonsey]

is that an expensive part?and where is it located?

[86VickyLX]

not expensive, it's under the hood, on the drivers side fender near the washer fluid reservoir, there are three relays there. The green one is for the fuel pump.

[Jonsey]

hmm ok.so could the temp be whats making it stick?Because it only does it in cold temps

[Tiggie]

Cold temps could easily cause the relay to stick.

[Jonsey]

so i should replace it then.i went outside and turned the key and it stayed on, but this time i tapped the relay and it stopped lol.Is that wierd or am i just dumb

[Blaze86Vic]

That's a definitive result then. Time to replace it. Tapping it will jar it loose and let is open again so that the pump turns off.

yeah, tapping the relay un-stuck it. It needs to be replaced. Its probably a less than $20 part.
