#376 of 400 CONFUSED FLOAT
Jan 18, 2010 (8:53 am)
I have a 2002 Chevy S10 that I just changed the fuel pump on. After changing it my float got stuck. We pulled the bed and *thought* we fixed the problem but I'm still having to check mileage. The weird part is that for a few days the gauge will stay stuck on full (even when it's not) then all of a sudden it will say its stuck on empty (even after I just filled it up) Any ideas?

Thanks for the heads up on turning the nozzle. I had the same problem with my 2002 S10 (also extended cab 4.3) last week and couldn't figure out what the deal was. Will try that next time.

Well it worked right before the pump change. I would go back to the sender unit, with a meter the resistance should read 40-240 ohms full to empty. If no problem there the connector would be next to check.

2000 S10, 4.3L, auto, 151k: Recently had radiator clog/stop up with red rust. Had radiator, thermostat and resevoir changed out, systen flushed and backflushed. After driving just 3 weeks, the water/coolant is red again. Obviously, I believe rust is still ongoing in the system. How can I stop the rust? Funeralman.
#380 of 400 Oil pressure sender?
Aug 16, 2010 (2:53 pm)
I have an '82 S-10 with an oil leak, not a huge one, but it's dripping down the back of the block from somewhere. I thought I'd try the cheap and easy fixes first, and I saw on this forum a couple of years ago a discussion about oil pressure senders leaking oil. Well, I pulled out my Chilton's, and it mentions nothing about this particular part. I assume it, or something like it, must exist on the truck, but the manual was no help. O'Reilly's carries an "oil pressure switch" for the '82 S-10, but without any idea of where it goes, it isn't much help. Any ideas?

I THINK YOUR OK. I HAVE A 2003 S10 45000 MILES AND MY COOLANT LOOKS A REDDISH COLOR. ITS CALLED DEXCOOL AND ITS ACTUALLY A ORANGE COLOR AND WHEN DILUTED WITH WATER ITS A REDDISH COLOR. PLUS ONCE IT REACHES OPERATING TEMP. IT CHANGES COLOR.

There is a vent valve that opens when you shut the vehicle off to allow the air to vent as you refill the tank. The problem is the valve is located on top the fuel tank, as part of the fuel sending unit/pump module. The service manual suggests to remove the truck box to access this

OK HAVE YOU CHANGED YOUR PCV VALVE YET. PCV (PRESSURE CONTROL VALVE) IS DESIGNED TO RELIEVE CRANKCASE PRESSURE AND FUMES. SOMETIMES THESE THINGS PLUG AND SOMETIMES THEY WEAR OUT AND PULL TO MUCH VACUME AND START PULLING OIL OUT OF CRANKCASE. HINT..... HINT...... DO NOT BUY ONE FROM PEP BOYS, AUTOZONE, ETC... ETC..... BUY ONE FROM GM DEALER AC DELCO. I THINK YOURS IS PLUGGED AND YOUR BUILDING TO MUCH CRANKCASE PRESSURE CAUSING YOUR LEAK OR YOUR NOT PLUGGED AND PCV VALVE IS WORE OUT AND YOUR PULLING OIL OUT OF CRANKCASE. PCV VALVE COST ABOUT 10.00 DOLLARS. GOOD LUCK TRY THIS FIRST!
