parts store or dealer item..

what about the temperature sensor which is the one according to message given to ECU get the correct quantity of fuel ?

if you can't get it to open from inside or out the lock broke get a new lock the open the window look down at the lock with a long screw driver break apart the lock it plastic

Try giving it a shot of starting fluid. You don't say if it's actually firing. If it tries or runs for a few seconds off of the starting fluid then try changing the fuel pump relay. It's inside of the glove box on the left hand side behind the little door. If that doesn't work it's most likely the fuel pump.

Go to your local parts store. Ask them for a AC bypass pully. You will remove your AC pump and replace it with the pully and bracket. hope this helps.

bad relay or a bad wire

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.
