SOURCE: Head bolt torque specs?

I really really really hope you turned the bolts an additional 90 degrees after torquing to 22 Ft-lbs. Otherwise, you may be taking that head off again.

Best of luck,

1997 geo prizm not starting getting too much gas

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?


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.

  1. 12vdc power to all EFI parts. electric power over 10v.

  2. good compression over 150psi all 4 cyl. (new timing belt?)

  3. tuned-up and hot spark timed right.

  4. good fueling. not to rich or too lean.

  5. 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?


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.

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.

engine size/capacity required ?? all the one's I've seen upto now would damage the engine if belt snapped. You need to know if yours is a non-interference type ie the valves do not intefere with the tops of the pistons at any point in an engine revolution.

1.8L stumbles when hit bumps in road. Messed

Wow, this kind of a problem can drive ya nuts. There are 2 different engines for this car, one is a model 4A-FE and the other is a 7A-FE. The problem sounds like a coil breakdown..I know it sounds nuts because it happens when you hit a bump, but it could be coincidental to a coil breaking down when under load. You will need a decent Ohm Meter to do the following. Check the coil primary resistance [4A-FE & 7A-FE both = 1.11 - 1.75 ohms], then check the secondary resistance [4A-FE & 7A-FE both = 9.0 - 15.7 kilohms]. If either of these values is out of spec, the coil will need to be replaced. If everything is OK, next check the air gap between the signal rotor and the pick up coil projection (CAUTION; use a non-ferrous feeler paper, brass or plastic). For a 4A-FE and a 7A-FE engine it should be .008 - .0016 in. If this air gap is not correct you have to replace the distributor housing. I hope that this helps to find / fix, or eliminate the distributor. If all this is OK check the lead wire from the could have a broken wire inside of the plastic cover. If still no luck, write back and we'll try again.

'95 Corolla Engine Question

An engine from another Corolla up to 1997 will fit. There are 2 engines though. 4A-fe (1.6L) or a 7A-fe (1.8L) They look similar but run different Engine managment computers. The 4A-fe uses a 3spd auto trans and the 7A-fe uses a 4spd auto trans. Also some of the wiring may be different.
Hope this helps.
