REFERENCE INFORMATION

The fuel pressure should always be greater than 3 psi

(21 kPa). If you get about the same pressure with the 2

transducers,

then you have a fuel system problem.

Remove fuel pressure transducer

(para.

4-30). Make sure

the STE/ICE-R

is powered

by a W5 cable.

You will have to decide if Test 24 gave the

wrong result.

If Test 24 gave a substantially

different result than Test

49, answer NO to this question.

NOTE

VEHICLE

foldout page for a way to run the rest of the DCA tests

in the TK mode.
