I don't know much about blazers, but i recently got a 1990 t10 blazer wich ever is 4x4. 4.3L engine.

about a month ago the engine started getting weaker and weaker. one day it wouldn't even move. it seems to move until it warms up.
i have put a new: ditributor, new computer (twice), Map Sensor, spark plugs/wires, Checked the injectors, Checked the fuel pressure, New rotor cap, and i checked the throttle body.
i have heard some comment about the injectors/harness maybe being grounded out. i have yet to check this, as i do not know how.

please send me your thoughts, i really want to keep this truck but i have a deadline of 1.5 months or i have to get rid of it.

does it turn over slower and slower? or will it just not start. How warm are we talking about before it starts?

 

oh no, it's starts fine every time. im not really sure what temperature, but after about a minute its hot enough to stop.
