fuel pump not working .

[cowboy wayne]

I was driving my 88 ezgo and the back tires locked up . I started it up and drove 100 feet and it quit running . i checked the compression it was 130 . It has agood spark . but the fuel pump isnt working for some reson . can someone please tell me what to look for

Missing or cracked, loose pulse line.
pulse line full of fuel is a ruptured diaphragm.

Is there anything that could have came loose internily or is it a simple fuel line or fuel pump ? thanks for your reply .

[cowboy wayne]

All fuel lines are new .

Do the simple stuff first. Has the tube inside the tank fallen off? Is the fuel filter blocked?
If this checks out then either the pump is shot or the crankshaft seals are worn. You can remove the pump but it can be hard to see a hole in the diaphragm. If it is split the cost of a new pump is slightly higher than a repair kit so you may as well buy the pump.

I checked all the lines and pickup tube . I also checked the diaphram , but like you said I coulnt see a crack or a hole .do the fuel pumps go out that sudden ? Thank you very much for your reply.

[Dave Box]

My experience is yes. One day it works and the next it is dead. That said, the pump needs the crankcase pressure oscillation to make it work. If the seals are shot you will have the same symptoms. You cannot see the front seal but you may be able to see if the rear is leaking by looking behand the clutch with a lamp and a mirror.

Thanks again for your help . After further inspection i found the rear seal completly blown out . Will change the front and rear seals this weekend .

[Dave Box]

When you replace them apply a generous amount of 2 stroke oil to the inner rubber surface and I like to apply a bead of Loctite Blue bearing sealant to the outer metal edge.
Good Luck
Dave

Will do AND THANKS again . As I started taking the drive clutch off I noticed up and down movement in the crank . Is there a bearing on the crank that iI need to replace ? And if so is it a good idea to put a crank kit in it while its apart?
