need help regarding my truck. Last night I turned the key off, and instantly went to start it back up and the starter wouldn't turn.

I've changed starters in this truck before, so last night I put in the new starter and same problem. I left the truck over night. 1992 GMC 5.7 350 automatic transmission.

so today I went back and really went through things. My first thought was maybe i had seized my engine. So i decided to check the flywheel and crank pulley to verify they'd move by hand, they did. (Did a full turn on the pulley) I ended up buying a third starter and verifying my wiring was correct.

What is happening is my starter is engaging the flywheel but not spinning. After releasing the key the starter stays engaged, until I turn the crank pulley, I can hear it click back into the solenoid.

I'm feeling like perhaps this is an electrical issue(Not enough juice at starter) today I did hook up starter number one and two to the battery but not connected to the flywheel and the starter engaged and spun just fine. Makes me think it never was my starter.

I know I need to take a voltage meter and do some readings but I'm also curious is there a starter relay? I can't seem to find information about this online.

thanks in advance

The freon was low, so I added 2 cans & a can of the oil additive. It brought the pressure back in the correct range and worked fine for a few days. Now it is blowing extremely hot air & the pressure is still correct. The compressor seems to be running ok. Any solutions?

its a 2 wheel drive ext. cab

Truck won't idle. Stop sign have to have foot on gas & brake.

I have a problem with my 96 2500. Sometimes, usually shortly after starting, the engine runs a little rough like it's running out of gas and wants to die and does die if I don't keep the RPMs up. It is difficult to start right after it dies. If I wait 5 minutes, it seems to start up ok. Seems to be a fuel related issue. If I spray some starting fluid in, it will start right up. It runs ok after it runs for a while. 116K miles.

Cold or hot it only has 115000 miles on it.had it hooked up to a code reader and it says tps but it's brand new.replaced 4times to make sure I didn't have a bad one.

will restart but kill again. after sitting a couple of hours sometimes runs great again. code reader came up egr decel fail. no other codes. runs great when it runs.

The car is dropping transmission oil across the transmission

I have a 98 k2500 with the 6.5 diesel and a 5 speed manual the repair shop can't give me an accurate estimate without knowing if I have the nv4500 or a different transmission. the vin is 1gtgk24fxwz502196. Any help would be great as the estimate doubles if it doesn't have the New Venture. Thanks.

I have had a 95 GMC in the shop for 4 months and it still running the same. Had rebuilt transmission, replaced TPS sensor, reground all wires, replaced 4 wire harnesses, replaced Alt. The problem is Once in awhile the Check Engine light comes on and the truck wont shift into 3rd gear, unless I park the truck and wait a few minutes and restarted it. Any Idea's what this "Gremlin" is?
