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.

These engines are common for running really bad when coolant temp sensor is bad. Disconnect it and see what happens. That way you can discard those little things. It located on the intake plenum.
If problem persists I would have someone check fuel pressure.
I hope this helps!
