92 accord-starts and loses fuel pressure and dies.it will do this every time i turn it off and back on.when i turn the key to run,fuel pressure is 40 psi.and as soon as check engine light goes out,fuel pressure drops to 0.when i start it,fuel pressure is 65 psi,then drops to about 20 psi.is it a week fuel pump or is there some sort of one way valve causing it to lose pressure?i have already replaced fuel filter,fuel pressure regulator,main fuel relay and cleaned injectors.can anyone help?PLEASE!!!!!!!!!!

 

Who the hell still drives Honda's.

people here will be no help.

 

sounds like a fuel delivery problem.

 

Did you get a tracking number doe?

 

THANK YOU CAPTAIN OBVIOUS!!!

 

What are the traffic conditions in your area? If it's rush hour and you're expecting a fuel delivery, you can expect to wait longer than you normally would.

 

You have a leak somewhere.

Take your fuel pump out and check the hoses on the pump.
Or could be the ecu.
Ecu triggers the pump for a predetermined time then shuts off untill the engine cranks.
If fuel pressure is dropping before you can crank the motor there's no pressure for the injectors to provide the motor with enough fuel.

 

Came in here expecting this

 

OP do you have gas in the tank? I recommend removing the gas cap and smelling for fumes.


I would also check for gas in the ashtray.

 

I have no idea what they are trying to accomplish in that gif lol.

they are facing away from teh bootay? for why?

 

 

Who serviced the injectors?

 

It doesn't get any more scientific than that.

 

mah gawd! he dun slapped dat midget and it didnt even flinch!!

supa bounce midget!!

 

 

Let's get on topic here for a second.


So you've replaced everything except the item that should've been tested and replaced first..... the fuel pump.


If you're pulling pressure from the fuel feed line and it's dropping, then that eliminates the injectors & fuel pressure regulator because both of those items come after the fuel line. If pressure is high, then drops low, that eliminates the fuel filter because a clogged filter will have low pressure all the time. If there's a kink in the lines, you'll have an extremely low or an extremely high pressure but it'll be like that all the time.

So you've pretty much eliminated every possibility of the fuel system except the pump itself and the wiring supplied to it.

At this point you need to put a DVOM onto the wiring to your pump and test voltage output during a start/run/off/start/run cycle. If there's a voltage drop or cutoff in there, you need to test continuity from your pump to your main relay. If the same amount of voltage is applied to the pump during the cycles, then you need to pull the pump out of the tank and measure how much voltage it draws compared with a new pump. If it draws too much voltage, then you need to replace the pump, but if it draws the same, then you need to explore other possibilities by looking at where the fuel is going into the pump to see if there's any restrictions (strainer, dented gas tank, etc.).


I'd say there's a really good chance it's just a bad fuel pump, but you'll never know unless you test everything. You can continue swapping parts til your wallet is empty or you can test items and spend only what you have to.

 

lulz, I hear it helps sometimes

 

I recommend converting your Accord to use the blood of a thousand virgins to power your car like the rest of us have done

 

I only use the tears of RA's forgotten children
