Question about 1987 Honda Prelude
CAr acts out of gas when at a half tank also won't start after driving to the store or a short distance acts flooded smells of gas and has no pedal pressure from the gas pedal. On the dash three lights pop on Pgm-fi and a small red light in the middle of one gauge comes on if I wait 20 min it usually starts again but batt is good and pump seems to come on the alternator is new, and starters ok
Pedal pressure? the throttle sticks< OPEN?
ive never ever seen a post ever for pedal pressure,
what does that mean? im clueless here, and sounds very scary.
to any mech. after all, throttle valves failures, can be man killers.
when failed does the engine crank over full speed with the starter?
grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr fail to start.
that normal sound of a good starter, yes?
is this an intermittent problem only?
NO start, ? (cranks robustly)
no, lets start at step one.
1: check all fuses. in both fuse boxes.
2: are the Headlamps working at full brightness.
3: does all the normal dash cluster lamps glow , key on.
Charge, Brake , Check engine lamp> all glow, if not, stop.
4: spark got spark at all cylinders, (a test)
my guess is engine is flooding, (smells) and is due to
ever do the 60k mile tuneup this decade?
this very old car has relic, warnings, back then.
the PGM-FI is early name for CEL, check engine
on this engine you must find the ECU (PGM-FI box)
and see the LEDs on the side.
they can be made to blink secret codes. errrors
these errors will be key to diagnosis, i bet.
here is the clue
the cars FSM book covers how to diagnose no starts
or no cranks.
