On my 91 RS 305, the coolant fan sensor is located next to the thermostat cover on the top-front of the intake manifold. If your fan is not coming on, it my be a bad coolant fan switch. The coolant fan switch is screwed into the block above the starter. It provides a conditional ground to the fan once the temperature reaches 225F. I replaced my coolant fan switch 3 times and my fan still wouldn't come on so I finally gave up and permenantly grounded the wire for the fan switch. So for the last 3 years, my fan runs continuously while the ignition switch is on. I also replaced the fan motor with one with a life-time gaurantee for $25.
AnswerWrong, the coolant FAN sensor is on the right side of the engine (if you are standing in front of the car facing it) under the exhaust manifold, the coolant sensor next to the thermostat only controls the temperature gauge in the car. =) That might explain why you replaced it 3 times and it never worked =)
where is the temperture sensor located on a 2002 chevy trailblazer with a 4200 motor
Yes. A bad or failing temp sensor prevents the ECM from monitoring, and adjusting for, the engine temperature.
It is located on the left side of the engine between the 6th and 8th cylinder on the block.

the knock sensor on a 91 camaro 305 in on the passenger side of the block, bellow the exhaust manifold. its a few inches in front of the bell housing., and has a single wire running to it. looks a bit like a temp sensor, or oil pressure sensor.
Map sensors were not used on 88 camaros. Only maf sensors
Fuel Pump relay on my 87' Camaro 305 TPI is located underhood on the right side of the firewall, its the second relay of the 3 or 4 in a row
It's located behind the passenger side kick panel.
Try replacing the engine coolant temp sensor.

if you have an 84 z28 camaro it has a 305 or a 305 h.o. 5.0L
It is located in the side of the engine block close to the starter . it has a single wire connector and it screws into the water jacket. So be careful when you remove it because engine coolant will come out
