I was driving it and it died at a stop sign,it has gas. It turns over but won't start, I removed gas cap and listened for fuel pump and its working. Any suggestions?

I just installed one on my truck and all it does is turn over. And it seems like the new key and cylinder are getting stuck on the on position, causing the new starter not to disengage

What is the issue. ?

Position. Because I hear a grinding noise when the engine is running, when I press the brake pedal the notice stops, how do I fix that. ?

It in 1st, 2nd, 3rd, 4th, 5th or reverse. How do I fix that problem.?

Greatly appreciated, thank you and it's hard to shift into gear

I put in a motor, but it doesn't want to start by itself, I did get it started by passing it thru the fuse box in the engine compartment

Super easy without any pressure

Mine didn't. Now what can I do or what are my options

Did I do something wrong or is that I need to start it up to get the hydraulic fluid flowing

I know that the tensioner only goes in one way

Is there something I have to replace to make the belt fit

My truck doesn't have a 4.3 vortex but the blazer does

It will run ok on flat land. It seems to shift ok when in town. But if you throttle it to pass or climb hill, it falls and acts like it is braking and downshifts.
