Electrical issues

Hello, bought a 2005 base model 4wd recently, V6 as a hunting truck. Runs great, engine and transmission very smooth. Have several issues with instrument panel I’ve been working on. Speedometer and odometer don’t work, and gas gauge will go to full but never drops below 3/4 even when empty. ABS, check engine, and parking break light always on. Had instrument cluster tested and no issues with it, replaced transmission speed sensor and all four wheel speed sensors with no luck. Dropped fuel tank and tested the fuel sender, resistance tests out and is working well. Tested a new fuel sending unit and fuel gauge still won’t correct. Does this sounds like a ECM issue. I’m no mechanic, just YouTube trained. Thanks for advice

 

While we wait for @TnShooter and @Dm93 and @Bishop84 to show up let me ask if there are any codes you have pulled? And if the brake master is full of fluid and the e brake is fully released.

 

I don't delve too deep anymore.

DM93 has a great resource page for this kind of stuff, including code P0500 which I assume is stored.

99% sure the only code that showed was P0500, the brake fluid is full and parking brake release

 

What codes

What code(s) are in the ABS module? You need to address any codes related to the rear wheel speed sensors before proceeding with diagnosing the P0500 code.

 

And here ladies and gentlemen we have another example of unfinished business.

 

That seems to be the case with nearly half the threads these days.
Question is asked, some answers are given, OP may make a couple replies then never returns.

 

Cats ate his face.

 

That sux

 

This truck is a side project, been super busy at work and haven’t had a chance to figure out the ABS codes yet, I appreciate you guys help. Hope I can get around to it in the next couple days.

 

No worries, everyone just figured you weren't coming back since you hadn't responded for a few days.

 

I finally got around to looking, I got ABS code 32 when I manually tested

 

That's for the left front speed sensor, that shouldn't cause it to stop reporting vehicle speed to the cluster unless there is another issue.

 

That’s what I thought, I’m just stumped as to what to check next

 

I'm asuming your tach and coolant temp works properly?
Have you verified powers and grounds at the imstrument cluster?
If that's all good go to my steps for diagnosing the P0500 code in the thread below.
