My MGB fuel pump is always ticking, is this natural or should they cut off after its primed itself

do not need to bleed unit

If its Petrol engine, the fuel pump should prime for few seconds and cut out. then it should run continuously once the engine starts turning. Please check if your exhaust has heavy black sooth deposits. maybe the cause for your high fuel consumption may be something else.

Many back then only had a little screen at the fuel pump, others had a single inline with the gas line at the firewall, many were added by owners or mechanics just before the carbs. The main problem with fuel delivery is the points getting stuck on the fuel pump. If its not clicking audibly when you first turn the key, tap the pump lightly to loosen the points. Yes, there are points in the fuel pump. about 2 clicks a second to fill empty carbs.

no start , crank perfectly
so , got spark?
the ECU has programming (ROM) and in fact kills all fueling with no spark , (even if it thinks there is no spark, even if spark is ok)
all ECU use a way to read back spark quality, (ALL){LAWS}
how honda does it in code, i don't know , see C R O M E forum)
turn the key over means nothing to me.?? sorry, it doent/
try saying what postion? cranking? or just keyon.
now some more EFI rules.
The EFI (some) do not activate the pump relay until cranking.
some do just key on for 3 seconds, read the FSM, its free.
need a link to the free manual? read the ECU logic on that.?
and prime has a special meaning, it means purge air,
its not for fuel. some system send a fast prime pulse. to clear air from the pressure lines, this plus does not inject.
that is how EFI works,

the flow
1: key on, ECU sends prime pulse, (air purge)
2: some ecu, run pump for 3 seconds, and pressure hits 35psi? RTM.
3: all ecu activate pump cranking and running.
4: now check pressure. !" 36 psi FSM stated spec"
5: now crank, if the ECU sees no spark errors, it injects
6: if the ECU sees WOT. it stops injection to clear a flood, cranking.
those rules cover most ECU made.

honda this year has a special feature called,
Fuel Cut-Off Control'
if this messes up, it i can cut fuel
does this help?
even better is this site, (has all the facts..)

the pump itself isnt any good. replace it and ride.

possibly the fuel metering solenoid on the injector pump playing up was common
or injector pump itself
depending on which type of injector pump you have the round switch things on top rear section of pump that have a single or 2 wires to it.

PRIME PUMP, OPEN AIR VALVE ON FILTER. OR TAKE THE LID OFF YOUR FILTER AND SEE IF IT STARTS TO PUMP... YOU DO HAVE IT PLUMBED RIGHT? THE PIPE COMING OUT OF THE PUMP GOES TO THE FILTER !! I'M YOUR LOCAL POOL PUMP REPAIR GUY IN LONGWOOD FLORIDA. WHERE THE POOL IS ALWAYS OPEN

Hi,
Here is a tip that will help you..

does it have a fuel pump ?...it could be just priming itself..when the pump is already full you cant really hear the noise that much. Does the noise go away after riding for awhile and then restart it?
