I have to crank my car twice before it will start The first time I do it, I crank it for a good 3 seconds and it would not start, then I would do it again and it would start right up. This only happens when the car is sitting overnight or while I'm in school so could it be something with the fuel?

 

Motor is a b20b

 

loss of fuel pressure from sitting most likely. Prime the fuel pump first (turn key to on (II) wait for the fuel pump to prime and shut off again, turn key to start engine. If that works you're loosing fuel pressure while sitting (hole in the fuel tank, leaky gas cap, etc.

 

Thanks, it works the way you say it. Is this a big issue or is it minor because I have other issues to fix and I want to fix the most important ones first.

 

It depends. If the fuel tank is leaking and you've got gas dripping you should deal with it right away, if it's an evap line or gas cap it's not a big deal.

 

Yeah there's no leak at the gas tank so I think it's ok for now. Thanks

 

Gasoline is very volatile, which means it evaporates quickly. So if you do have a gas leak, it would have to be small. Like a drip every 30 seconds, maybe every 15 on a searing hot day. But you can never be absolutely sure unless you video tape it for an extended period of time.

 

could be the fuel pump is going bad.
loosing pressure over several hours or overnight is a possible sign of a bad check valve inside the pump .
theres a video on it on eric the car guy when he visits fuel pump company on youtube .

 

Thanks for the help guys, I will try to look forgas dripping. And thanks for the video, I will be sure to look into it a bit more after I fix my tranny oil leak.

 

Fuel leak is so unlikely. Pinch the fuel pressure return line off with vice grips while the car is running, then shut the car off and leave it overnight. If it starts right away in the AM with the vice grips still pinching off the return line, then your Fuel pressure regulator is faulty. If it doesnt, then its most likely a faulty anti-drain back valve in the fuel pump assembly. *Before you do this though, listen and make sure the fuel pump primes every time you turn the key to the "ON" position, cuz if it doesnt, then try replacing the PGM-FI Main Relay
