my R33 wont start.

[trev.]

R33 wont start. found blown fuse in fuel pump circuit. swapped out relay. proved ok, fuse still intact. Pump mounted in the bottom of the tank, unlike any of the examples I can find on line. Cant get fuel pump or float mechanism to release. need help pse.

So, let's unwind this a little.

1. You had blown fuse. Replaced it, and the relay. New fuse remains good.

2. ???

3. Profit?

But seriously, is the pump running? If it is not running, is it at least getting power onto its wiring when it is supposed to? What tests have you done? Listen for pump? Multimeter on the power wire? Fuel pressure gauge?

If we presume that it is not running, having failed any or all of the above tests, that would explain why you're trying to pull it out, yeah? So at what point in the process of pulling it out are you having trouble? Have you unscrewed the clamp ring? IS the plastic hat just stuck on its seat/o-ring?

Can you expand on this? If the fuse blew then there is a fault that needs further troubleshooting. A relay is highly unlikely to blow the fuse.

And you don't want your float mechanism....it has f#ck all to do with any issue you have.

If you are trying to get your fuel pump out I suggest you have a look in the tutorial section of the forum....quite a few good people have contributed threads on this sort of topic.

Just check if your pump is working, i had the same problem, easiest way to check is find your fuel filter follow it to your engine, disconnect thr hose, get some rags around, and try to start your car, if fuel piss out then you know your pump is working, if nothing comes out then you know its your pump
