CPS Plug inspection. Is this normal?

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. 

You're right. I'm going to HF today.

I know the fuel pressure is low as it doesn't spray. However, a pressure gauge will be helpful. The injectors work. I had them all out, cleaned and tested them. Will test for spark tomorrow.

You're only 3.5 hours away. Just swing by tomorrow! LOL!

I admit it. My troubleshooting skills lack organization.

a noid light will determine if the injectors are getting signal to operate,not the actual function of the injectors.remember an engine needs spark,fuel and compression to run.i doubt it suddenly lost compression but i have seen stranger things but its highly unlikely.trust me if i were closer i would swing by.

Just to verify. https://www.harborfreight.com/11-piece-noid-light-and-iac-tester-set-97959.html

 

Thus will work for renix MJs?

[ratrapp]

yes,even the renix 4.0 uses ev1 style injectors that are pretty common.

[ratrapp]

there will be one in the kit to check injector pulse.it might not be labeled ev1 but there is one in there.

Well, I have spark. Fuel pressure whilst cranking starts at 39-49 then suddenly drops. At the same time this is happening, I noticed fuel dripping from the fuel pressure regulator/fuel line connection. This may be the problem. Thoughts?

that's a top priority.

That's tomorrow's plan!

did you verify injector pulse and you said you have spark,but did you just spark at the wires or did you pull the plugs to see if maybe theyre gas fouled?
