Re: Please help, unusual no-start condition on '97 Vortec 5.7L
The IAT (Intake Air Temp) sensor is located in the inlet tube just as it comes out of the filter box. The MAP (Manifold Absolute Pressure ((AKA manifold vacuum)) ) is located between the throttle body and the dist.
Really should hook up a scanner that can read these sensors and see if they need to be replaced.
The IAT should read ambient temp and the MAP should read current barometric pressure (engine off-key on).
Also need to check the TPS (Throttle Position Sensor). With the throttle closed the voltage should not be more than 2.5 volts.
