Thread: Long cranking time

The check valve is located inside the fuel pump, accessible from a hatch under the rear load area carpet. It isn't separately serviceable. The pump can be replaced with a generic Holden Commodore pump but you must be extremely careful to not damage the plastic pressure hose on the outlet. If you do you'll need some special submersible EFI fuel hose to replace it at around $30/foot.

Also check that your fuel pressure regulator (at the back of the engine) isn't leaking from either the vacuum port or the outlet hose when the engine has just been switched off.

Thanks Bee utey, I have checked the vac hose from the press reg to the plenum and it seems ok, although i did cut 10mm off it to get a better seal. I will see if that makes any difference.
With regards the fuel pump, are you saying the fuel pump is interchangeable with a Commodore one? Do you have a part no and can I get one from Bursons or Repco? The manual shows a special tool to remove the pump/qty sender unit from the fuel tank, can it be done without this tool? If I don't change the pump I suppose life will go on just requiring a bit more cranking.

1. You can purchase a good quality Bosch pump kit part number BFP772 to suit various vehicles including Commodores from any store that stocks Bosch products. I forget where I bought the last one, could have been Bursons as I have an account with them.

2. To start your engine without a long cold cranking time, just switch the ignition on and off a number of times before cranking. Each time you turn on the ignition the pump should run for a second or two.

3. A large hammer and a blunted flat screw driver can usually loosen the pump locking ring so long as you aren't brutal about it. Don't belabour one tooth of the plastic collar, a few blows to each tooth in turn will get it loose. Blow all the crud away from the top of the tank before you proceed though, you need no extra sand in the tank.

Thanks bee utey , at least now I have a part number. I have found that pump online at Bosch, $83. Is it just a matter of removing the pump/ qty sender unit from the tank and swapping the pump assembly with the new one from the kit? Does the kit have everything I will need? Sorry to go on about this but I want to know what I'm up against before I start disabling the vehicle by removing the pump.

If you doubt your ability to replace the pump perhaps you should just leave it alone. The plastic outlet hose on the pump can be difficult to get off intact, I've used a small hammer and a block of wood to crush the plastic outlet fitting of the old pump and removed it in pieces. Otherwise get yourself some proper submersible fuel hose to replace the plastic with, e.g. :
