It doesn't seem like it's that hard of a fix. I have a little exp working with a soldiering iron and working on something with parts that large sounds like a breeze to me. Much better then micro soldiering on a mother board. If I can source the caps then I may be okay. I'll have to swing by the shack when I get off work in the morning. Thanks all. I will let you know how it turns out as soon as I get it done

Radio shack has the caps. Make sure you get the 35W or better. I cant remember if they are 27 mf or 17mf or a few of both. ( and not trying to be a smart azz, but they are electrolytics, so they have a polarity and only go in one way. Pay attention to the old ones b4 you remove them.)

Personally, I'd rather obtain them from an electronics supply house, instead of R-shack.

You can always order higher quality caps off the internet.

yes if the pcm doesn't get signal from the CPS it will not engage the circuit for the coil of fuel pump. this is how the pcm keeps the engine from getting flooded with gasoline.


i know this problem has been solved but since i'm having this exact problem i will be opening up my PCM this coming weekend (my yj has a 93 zj 5.2), so this is also my way to sub for future reference.
