My van runs better with etc sensor unplugged

Asked by Apr 13, 2018 at 11:02 PM about the 1996 Chevrolet Chevy Van

Question type: Maintenance & Repair

I have a 96 Chevy g30 van. It will hardly idle, and
will die when put in gear unless I remove the ect
sensor, in which case it will run great when first
starting but shortly gets rougher, eventually dying
at idle and loosing power at speed. A new ect did
nothing for me. The van has new spark plugs and
wires. New distributor cap, and rotor. New fuel, and
air filters. New ignition coil, fuel pressure regulator,
thermostat, and housing, throttle position sensor.
And both Map, and IAC sensors are both new. It
throws codes for high vacuum, and low coolant
temp, along with fault in the fuel pump circuit. But
the fuel pump seems to be pumping away. I am not
a seasoned mechanic, and am at my wits end.
Hopefully someone can point me in the right
direction.
