Sup HT, I got this problem with my car not starting up when it rains or gets hot outside, but it does start up when it is in the morning or night. So, earlier around 9ish I went outside to go start my car up, and when I turned the key to the on position my check engine light did not click off and I did not hear the fuel pump. So, I pressed the gas pedal a couple times and my check engine light clicked off and then I heard the fuel pump and my car started right up. Does this mean that my fuel pump is going out? If so, does this mean that when my car doesn't start up when it rains or gets hot outside is cause my fuel pump is going out? Thanks for reading.

i would check some grounds, that can be the culprit to weird things like that sometimes. You may want to give the ect sensor a check also. The cel going to with the pedal pushing then the pump going, i dont really know.

Sounds like the main relay is bad. You also might want to check or replace the plug wires.

main relay wont cause the cel to come one though will it and why would pedal pushing make it work oddly? Usually with the main relay if its bad you can try cycling the ignition key a lot and it may work a couple times?

A bad main relay frequently causes the CEL to light.

This is likely a coincidence.

Yes, a main relay problem can be intermittent until it completely fails.

I am also having similar problems. when i go to start my car i can no longer hear my fuel pump. Im hoping its the main relay.
