So a while back I had a cracked bellhousing, I changed that n ended up having to replace my clutch so I bought a new clutch kit, now when I go to start my truck it will turn over but slow and then it does a grinding and u can hear the starter winding I think. And now my battery will sometimes not be charged . I've been pop starting my truck and it starts rite up. Now when I'm driving it starts to act like it's not getting fuel n will die sometimes . I've been stranded on side of road many times n I don't know what to do .. my truck is a 1980 gmc Sierra grande 4x4 4 speed with a 1985 454 out of a motorhome

What is exactly meant when you say the battery “will sometimes not be charged”?

Given your doing cranking without the engine firing it can be more amps are being removed that the alternator has run time to restore. This then leads to the question of whether you are using a charger to pump the battery back up between cranking rounds?

Have you checked battery voltage with a reliable gauge? If so what is the value? Additionally with engine not running if you load the battery with lights on, stereo on, etc. where does the voltage go and with everything turned off in like 5 minutes later does the original voltage return or not?

What I’m trying to get at is whether the battery is holding up its end of the bargain.

I figured out the fuel problem. Fuel pump was not pumping enough fuel so went bigger.
As for the starting.. it turns over but starter makes awful sound like binding up . So I'm trying shims now.
For the battery issue when I turn lights on all my gauges quit working and my blinker lights inside stay on .. when I turn lights off everything works again but my voltage gauge will be between 8 and 13 after I drive a while it goes to 13 or just above 13 but if I shut off n try n start it goes down n won't stsrt..
