2 fuel pumps in one month!!! please help!!!

I just got a 90 240sx coupe w/ a ka24de swap a month ago, and I have already burned out 2 brand new fuel pumps. What the hell would cause this? If you have any info whatsoever, please e-mail me at baggerofteaness@yahoo.com . Any help is appreciated!!! Thank you.

hmmm... you wouldnt need a ka24De fuel pump would you? it might still have the ka24e pump and it works too hard to supply it maybe bigger injectors. idk much about the differences in the two but it seems like it might be working too hard.

Same pump as DE. All of the pumps are the same. 89-98.

did you replace the sock? Replace fuel filter? Check wiring. Check grounds.

alright. thanks for clarifiying that for me...

wiring is good, fuel filter is branf new, but I just got a new sock today. Would that cause it to burn up twice though? I'm scared to drive it anywhere now, due to getting stranded. Thank you for the reply!!!

sure its the pump then?
its entirely electrical(as far as anything that can really fail) so its gotta be wiring of some sort, either internal or harnesses


or...
trace the wires back to the fuse box to see if anything else uses the same fuse or ground. im not sure if it does but check the condition of anything that uses the same fuse or ground.

Ok, I just replaced the fuel pump sock this morning, and hopefully it was the problem. I would still like some answers though. If anyone has any clue what else would cause this, please inform me. I appreciate all the halp I can get. Thank you,

I couldn't tell you with 100% confidence that it is/was the sock. But you def need to replace the sock when replacing the pump.

I talked to my dad this afternoon, and he said to check the fuel pump relay. He's a big ford guy so he didn't know where it would be at on my car. Does anyone else know where it might be? I really appreciate the help guys! Thank you,

im sorry about the basic question. or to interupt your thread. whats a sock?

you could be running to manny volts to the FP. have you tested the load in the wires? do you checked/replaced the fuse with a lower rated one or prehaps rewired the pump yet?

A sock is a pre-filter for the pump. It attaches to the pump inlet to keep large debris from entering the pump.

Looks basically like this. Mind you, this is not a 240sx fuel pump or assembly. Its from a mustang, but same basic idea.

There is no relay to my knowledge. Too much voltage is unlikely. Too much load on the pump is more likely than anything. Lets see if that new sock works.

Ok man, thanks a bunch for the reply. I really appreciate the quick posts. While I have a thread, does anyone go drifting in K.C. (area) Missouri? If so, where at? Thanks again,
