Default Does sc300/400 use the same fuel pump

Will the same fuel pump fit on a SC400 and Sc300. I have a 1992 SC400 and my code says that the fuel pump controler is bad. I am in search of the right fuel pump. I need to take fast action fax or call 478-737-1704

Yes same pump and why not just do the bypass mod if your fuel pump ecu is bad?

Default still will not start

The fuel pump bypass did not start car does this mean that my actual fuel pump is bad?

or it could mean you aren't getting enough voltage out of the wire to the pump(like me)

What about jumping the under-hood connector? Connect Fp to B+ and the pump should run any time the key is in the on position.

(I assumed you meant you previously bypassed the FP ECU at the ECU connector)
