Those connectors were poor. I plan to. Finally got the old one out! Whooooohoooo!!! Need to read about your mod to this too! Link to comment Share on other sites More sharing options...
cruiser54 Posted April 19, 2023 Share Posted April 19, 2023 Gonna drill the upper hole? Keep this in mind when going back together. Link to comment Share on other sites More sharing options...
ratrapp Posted April 19, 2023 Share Posted April 19, 2023 i second the suggestion of bypassing the connector.i have personally done it several times on different renix 4.0s over the years. Link to comment Share on other sites More sharing options...
NC Tom Posted April 19, 2023 Author Share Posted April 19, 2023 The tape is ready for deployment. I don't see how you get a drill up in there, so probably not. I'm actually kinda backing off the whole mod thing. After reading about all the people breaking their new CPS! I can't afford to keep buying those things.

I really thought I read on your site to drill out the bell housing with a pic if the bell housing. I'll have to check that again. I must be having a serious senior moment!

NC Tom Posted April 20, 2023 Author Share Posted April 20, 2023 My Dr. likes to say. "As we age . . .", before the bad news hits. Here's the image that cornfused.. I did even notice the CPS, just the bell housing and the hole. 2+2=7 in my head. Ugh! Link to comment Share on other sites More sharing options...

JZLAJeep Posted April 20, 2023 Share Posted April 20, 2023 I thought I had a picture, but can't find it. We replaced the CPS in December. I had purchased a cheap one on Amazon, and it worked, but only after some modification. The holes on the CPS didn't line up with the holes in the bell. Fixed that with some cutting and grinding to make slots on each end. Then the pins of the plug on the new CPS were mangled so cut it off and spliced in the old plug. But after that it worked fine...

Whew! I thought this was going to be a horrible experience, but it worked out. Hoping my NAPA part will work right off. Link to comment Share on other sites More sharing options...

Still no start. Notched the cps I'm getting .08 volts. That's worse than the old one. It's a Napa part. I'm pulling my hair out!!! Link to comment Share on other sites More sharing options...

cruiser54 Posted April 21, 2023 Share Posted April 21, 2023 Maybe you should drill out the hole in that and use it. Did you drill the new Napa one? Link to comment Share on other sites More sharing options...

cruiser54 Posted April 21, 2023 Share Posted April 21, 2023 Only improved the output. Did you hold the sensor down against the bell housing while tightening? Link to comment Share on other sites More sharing options...

ratrapp Posted April 22, 2023 Share Posted April 22, 2023 i think you really need to take a step back.first where ive read youve never actually checked fuel pressure,just pushed the schraeder valve in and seen some fuel.harbor freight sells cheap enough fuel pressure gauge kits.then if you have proper fuel pressure and flow,check for spark.i persoally wouldnt have worried about modifing the cps sensor until i had it running again.i know you did put a new pump in it but i own a garage and you won't believe the amount of bad new parts i get a week(good american quality lol)you can also buy cheap spark testers from harbor freight.also you havent checked for injector pulse either with a noid light which also can be picked up at harbor frieght pretty cheap.most of these harbor freight tools are decent enough for the diy'er.
