are walbro 255's supposed to have continuity between the power and ground terminals?

i did a test on my walbro and it shows 1 ohm of resistance between the two terminals

this was done with the pump out of the car and not hooked up/ to anything

when i hook the pump straight up to power and ground on a battery it still spins.....

but when in the car, it does nothing, no fuel pressure, not even an attempt to spin(the pump)

i have checked my main relay and it is working fine. there are no loose connections from the pump to the main relay.

the main relay is also getting power to all the coils.......


any crx guru's feel free to give advice

thanks in advance

 

My advice, grab a length of wire and just start attempting to jump the pump to see if you can isolate the location of a possible wiring problem. Start nearest the pump and work your way toward the fuse panel and on toward the battery.

 

ok here's an update on what i did, just put the pump back in the tank and now the fuel pump is building a little bit of psi(20) and bleeding off somewhere. There are no leaks at any of the lines. I measured the yel-blk wire going from the main relay and the fuel pump at the relay and at the pump with the key ON and they both came out at around 11-12 volts right when the main relay clicks. Then after it clicks again the voltage dropped to around 6-7 volts. The other yel-blk wire coming from the ecu measured around 13v constant.

Any advice or suggestions would be greatly appreciated

 

ok so the problem was a bad ground at the pump assymbly......now my fuel pressure regulator won't hold any pressure.....??!?!?!?!?!....... it goes up to 60psi and then drops back to zero a shortly afterwards........took the return line off and ran it to a bottle and it bleeds off a little bit.........also my injectors arent firing? it's got roughly 12v at the main relay(pin 7)........and nothing where the injectors are........


let me know if there are steps im missing

 

any help would be nice
