cranks fast but will not start.
which engine?
ever do a full tuneup on it, the 60k mile service (interval)
????????????
this engine really is a toyota corolla.
getting too much gas
what does the mean,?
spark tips soaking in fuel.
fuel dripping out exhaust ports to ground?
what?
if flooding did you crank wide open throttle yet, (per oper. guide ins)
????????????
this is called super secret unflood mode, it cuts fuel cranking,
all cars, do that.
this should be your engine, to fix engines, know what you have.
late 1997 change.?
1.8 L
1ZZ-FE (LV6) I4 (
gasoline)
DOHC 4valve.
chain cam.
here is the secret to running.
- 12vdc power to all EFI parts. electric power over 10v.
- good compression over 150psi all 4 cyl. (new timing belt?)
- tuned-up and hot spark timed right.
- good fueling. not to rich or too lean.
- EGR not stuck open, clean it. or ISC stuck closed, clean it.
The ECU works overtime to start and sustain running.
so it failed. this means something is very wrong.
check engine light on key on,? if not fix that.
then connect scan tool and crank for 5 seconds.
got CMP/CKP or spark errors DTC , any at all?
or scan RPM at 0 cranking?
bingo.
scan the ECU. 1st after checking all fuses.
tuned up,, that is 1st.
if car as VVT-t , option it can fail and cause retarded timing and hard starts.
see the valve cover, here. got VVT-I? I think you dont have this motor.
http://en.wikipedia.org/wiki/Toyota_ZZ_engine#1ZZ-FE i think you have this
1993-1997 Geo Prizms were powered by the
4A-FE or optional
7A-FE engine.
as you can see ,knowing what engine is in your car is everything.
4a/7a engine is a belt drive cam.
so did you skip the belt service, ?
if you let it slip, it will not ever start.
the 7a motor will bend its valves, if the belt is ignored.
it is a DOHC , interference engine. so....
the service schedule for the 7A is. 60k on belt
spark plugs and filters
dizzy (distributor engins) new cap/rotor and spark wires too.
