Re: Overheating Problem?
Wow, quite a list!!! How long has this vehicle been neglected? I am willing
to bet that this truck had quite a few problems even before the no-start
Google 'EEC IV codes' and you will find what these codes mean in some
The usual word of wisdom is to attend to the codes in the order that they
are read, as one failure often affects more than one code. I don't know if
these were all stored in memory or from on demand diagnostics (if you even
ran on-demand diagnostics at all), and whether you listed them in any
particular order or not. You did not mention the engine size either, which
Assuming that these codes are valid and not some accidental misread, here is
my 2 cents:
332, 335: have to do with out of range EGR flow reading (probably not the
reason for no-start, but a wide open EGR valve would make the engine stall
at idle, so not impossible)
10: cylinder balance test failure (not sure which cylinder -- I suspect that
you misread this one)
122: out-of-range throttle position sensor. Doubt if that's the reason for
no-start, but needs attention.
181, 189: lean mixture (vacuum leak or insufficient fuel delivery - see next
543, 556: seem to point to fuel pump relay (or circuit) failure
600-range codes: various transmission issues - not good news, but most
likely unrelated to your complaint.
