This vehicle is fixed. A simple fix really, but there is a
point I'll make later.
I have an apprentice for the last 2 weeks. Smart guy, 34 yrs
old, IT professional, going to vocational school and making
the move to auto mechanics.
Complaint on the RO reads "Customer was at Jiffy Lube when
vehicle died. Cranks won't start, white smoke coming from
tailpipe". One hour diag. So we walk out to the car with
Tech 2, testlight, plug socket and screwdriver. Quick scan,
no codes, cranks strong, no RPM while cranking. Check for
spark, no spark. Pull random plug, clean and dry. Check
fuses, blown 15A fuse marked ELEK IGN, swap with 15A CRUISE
fuse and car starts immediately. Drive it in shop, leave it
running...seems to run fine, fuel trims perfect. All fuses
appear original, very old.
So here's a chance for a lesson...what blew the fuse and how
much time do we spend looking for a short? Go to Alldata and
print a schematic, this fuse feeds the ignition module.
Quick visual, engine harness intact, correctly routed, no
sharp edges, no exhaust contact, no rodents chewing,
nothing. Hook up my 20A Fuse Buddy in place of Elek Ign fuse
and get this: Amp draw
What's next? Can we ship it?
