Title: no fuel being pumped Post by: jack1 on March 15, 2011, 11:29:21 PM hi all,,all fuel lines are clear and a brand new pump fitted and plenty of fuel in the tank,,,,is there any reason that the pin behind the pump would not work???
Title: Re: no fuel being pumped Post by: mirafioriman on March 15, 2011, 11:37:25 PM Is it in contact with the cam inside? Some pumps use a spacer block some don't.

What do you mean by the "pin"? The lever that makes the pump work is part of the pump so it can't be put in without it. Does the rotor arm in the distributor turn when you crank the engine? (check by removing the distributor cap and cranking the engine) Title: Re: no fuel being pumped Post by: jack1 on March 16, 2011, 01:01:20 AM 'pin' the pin about 2inchs long that hits the lever in the pump to make the pump work

Title: Re: no fuel being pumped Post by: david on March 16, 2011, 09:03:51 AM Maybe the diaphram inside has a hole in it? this would stop it pumping.
Take it off the engine and get a piece of pipe and some fuel and check it by hand if it doesn't work will probably be dud diaphram.

[/quote thats not what the pump looks like,,,feed goes in from the bottom and outlet is from the top ,,pin is about 40ish ml long and slides into the block and then the pump slides on over the bolts and into place Title: Re: no fuel being pumped Post by: kev131 on March 16, 2011, 11:14:37 PM Maybe you should describe the car and engine Ivor...? ;)
Title: Re: no fuel being pumped Post by: jack1 on March 17, 2011, 02:26:57 AM Maybe you should describe the car and engine Ivor...? ;) [/quote yes that might help,,,its a 1980 128 1300 Title: Re: no fuel being pumped Post by: kev131 on March 17, 2011, 08:20:42 AM I see you have a 132 1800 ES on your signature now as well - Reality or an ambition...? :)
Title: Re: no fuel being pumped Post by: Thotos on March 17, 2011, 10:56:24 AM yes that might help,,,its a 1980 128 1300 Oops, sorry! I just assumed it was a 131. Ignore everything I've said in that case. I love 128s (I want a green 1100 as a daily driver ;D ) but I know nothing about their fuel pumps. Title: Re: no fuel being pumped Post by: stathe174 on March 17, 2011, 11:44:10 AM Try to suck some fuel to the front from the reservoir and then try throw some directly in the carb. This should make the pump going ;)

Title: Re: no fuel being pumped Post by: mirafioriman on March 23, 2011, 11:13:30 PM The fuel can not be getting to the cylinders. Is there fuel in the float chamber?
Title: Re: no fuel being pumped Post by: jack1 on March 23, 2011, 11:47:02 PM i know the plugs seem like there getting no fuel dave and dont smell of fuel after continuous turning over??? float chamber??
Title: Re: no fuel being pumped Post by: mirafioriman on March 23, 2011, 11:52:02 PM Has the car not been used for a while? Perhaps the needle valve in the carb is stuck shut?
Title: Re: no fuel being pumped Post by: jack1 on March 24, 2011, 12:06:11 AM needle valve??
Title: Re: no fuel being pumped Post by: mirafioriman on March 24, 2011, 12:10:24 AM Need to know what carb it is really but on most you remove the top cover, the chamber should contain fuel.
Title: Re: no fuel being pumped Post by: jack1 on March 24, 2011, 12:18:01 AM hmmm,, its a weber carb flap on top worked by choke and a flap down at the bottom ,,when you pump the accelerator by hand it lets the fuel into the carb
Title: Re: no fuel being pumped Post by: Tas131 on March 24, 2011, 03:32:40 AM when you pump the accelerator by hand it lets the fuel into the carb If your accelerator pump is delivering fuel you've got fuel in the float bowl. If it won't fire when turning over and pumping the accelerator, it's either flooded, (plenty of fuel) or you've got a spark/timing problem. In which case it should still cough and fart if the timing's anywhere near where it should be. Title: Re: no fuel being pumped Post by: Thotos on March 24, 2011, 11:10:02 AM It's rather common it seems to get the timing 180 degrees out (I certainly fell for that one :-[). With the timing marks aligned it is number 4 cylinder at TDC and ready to fire and not number 1 as most assume. So double check the ignition timing by setting up the camshaft/crankshaft marks and removing the distributor cap to verify that the rotor arm is pointing at number 4 cylinder position.

[/quote plugs are bone dry(if flooded wouldnt they be wet?) got spark at the plugs ,,, have checked the timing and everything seems to line up spot on???????

[/quote firing order is 1,3,4 and 2 ,,,,,,, isnt (2 ) actually cylinder 4 so rotor arm should point at the third cap on the dissy ?? does this make sense Title: Re: no fuel being pumped Post by: Tas131 on March 25, 2011, 12:35:01 AM It's rather common it seems to get the timing 180 degrees out (I certainly fell for that one :-[).

Yes and number 4 cylinder is the one nearest the bulkhead. |
