Ok hey guys I've been on the forum awhile I lost my other account info so here's my new account but anyway,

I have a 98 and it's got a new alternator, starter, cap,rotor, plugs wires, cksps, coolant temp sensor, and new battery.

It's throwing a couple tranny codes and the NSS sometimes Dosent work.

I had it running earlier today but it was running like garbage ran codes and it was a p1694 which came out to be for the crank sensor. Replaced that then go to start it and the starter just clicks and clicks.

I bought it has a donor but I need to know if it runs good enough to swap the engines.

The battery is fully charged and new and the battery gauge on the dash is only reading 8-12 volts and fluctuates from there.

I used my power probe to jump the brand new starter and still it just clicks.

I'm thinking the computer is fried.
Would a 2000 computer work on the 98? The throttle body's switched over but will the computers?

If you're jumping the starter, then the ECU isn't involved in if the the starter cranks. I would check your battery connections and grounds.

It started fine this morning tho multiple times EVERYTIME I tried it would it was just running like crap. But in the time it took me to replace the crank sensor it stopped working.

I get that, but if you're jumping the starter, and its just clicking, its either a starter issue or a power issue, because by jumping it, you're bypassing the ECU, the NSS, etc... I'm not saying your ECU isn't messed up, but it isn't what is causing your starter to just click when you're jumping it at the starter.

It's blowing my mind I have good solid grounds and have 13 volts at the starter. The starter is 3 hours old. I just went and exchanged it.

What would CUASE my volts gauge in dash to only read 10 volts and act like it's only got ten volts?

Well I figured it out guys.

I brought my DVOM home from work and found that I have very bad ground wires with very high resistance 3 volt drop in one of them.

Not surprised.

^X2 all to often I have saw this happen over the years on so many different things. That is the only way to find it and at times that has failed me unless the wire has to be moved to find it in the connection interment.

Correct. Unless you have super-powers and can SEE electricity, never assume the basics are good.

Thank you for the follow up. This should help someone in the future.

I guess I should be more specific, it was the battery ground to block that had all the resistance

That's one of the most common wires to go bad, as it is exposed on the ends and suffer a lot of heat/cold cycles, along with water splashing from the road, and sometimes even salty water.
