2.0 Efi Fuel Pump

[Guest neil gale]

My 2.0 efi pinto has a new cosworth fuel pump, and runs smoothly all the time, but for some reason the fuse blows now and again.

 

Its not a regular occurrence, but has happened twice now in 200 miles or so, but only when the engine is warm (or seems to be the case)

 

Anyone any ideas???

Does the cosworth pump use the same rating fuse as the 2.0 EFi pump?

 

is it a more powerfull pump that takes more current that could age the fuse?

I reckon it's probably a dodgy wire somewhere shorting to earth every now and again. If the pump does want more than 30Amp then don't just replace the fuse with a higher rated one. The wiring is only 30Amp. If you increase the current the wiring may burn out, over heat, or even ignite!

Hi

 

Does the pump have a power rating writen on it? A pump drawing 30 Amps would be rated at about 360 watts which seems like quite a lot. If you have an ameter can you measure the normal current draw?

 

Cheers

Im not sure if the pump has a rating, but like you i suspect if it draws more than 30 amps then its a wiring problem, even cosworth fuel pumps arent that powerful.

 

Will have a look and see if i can find a rating somewhere on it, and check all the wires.
