sound you have a blown clutch slave cylinder

Just to clarify what you said, if it cranks it turns over.
If it won't start, you would check for spark at the plugs and fuel pressure at the rail. Vortec engines need at least 60psi fuel pressure to start. If you have spark you could try spraying carb cleaner into the intake hose to boost the amount of fuel as a test.

Go to your local parts store and ask for the diagram, you can even go to the delers and they will help.

My first thought would be: If you repaired an emissions hose, take the car back to Auto Zone (or another parts supplier) and let them tell you what code comes up now. You eliminated one problem, now you have to find another.
I wouldn't do a fuel pump without more information.

I need to know which wiring diagram you need, powertrain, exterior lighting, engine management?

It's not worth doing all that conversion, buy the time you spend the time and money to convert the 89 4.3 to work on the 98 blazer, it would be cheaper to install a 98 vortec rebuild. The 89 4.3 have a TBI fuel injection system and the ecm on the 98 will not work and the bad news is that the ecm on the 98 also controls the transmission shift points and the 89 will not, so even if you swap the ecm to have the 89 4.3 engine work. the transmission will not shift. Sorry for the bad news but it would be cheaper to replace the 98 engine with the years of 1996 to 2001. Good luck and hope this helps. 

you have to remove the cover over the torque converter 4 bolts holds this on .you may be able to just move it out of the way. and yes it does sound like a starter problem.i hope this helps

i have a 1993 blazer 4.3 w code 4x4 with a 4L60 E . my truck wouldn;t go in 4 hi or low. so i changed the transfer case motor and it works fine now. If you turn the ignition key to on but not crank the engine and open the driver door and push 4 hi button, you should hear the transfer case motor cycle for 3 or 4 seconds every time you push button and the light will flash until it goes in 4wd If the 4 hi button light doesn't flash during cycle then it could be a bad switch. if the transfer case motor won't cycle it could be a fuse or a bad transfer case motor . Hope this answers your question.
