Question about 1989 Geo Metro

Open Question

1989 geo metro lse surges at about 2500 rpm. controlling the throttle with my hand i can watch as the injector cuts out and then sprays fuel again. It also has a rough idle and seems to be running rich fouling out one of the spark plugs. My 1989 Geo Metro surges between 35 & 40 mph or 2500 rpm-ish.

SOURCE: how to change water pump in 1996 geo metro?

I've found the Haynes Repair Manual that you can get at Auto Zone to be the best one there is. They have step by step instructions with pictures on repairing or replacing just about anything on your auto. You can get them for around $20 - 25. Is yours a 3 or 4 cylinder? Auto Zone has a new service where you can actually look up repair instructions for your vehicle with pictures. Here's the instructions for a 3 cylinder for your year, make and model:

  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
CAUTIONWhen draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
  1. Remove the air cleaner assembly.
  2. Loosen but do not remove the four coolant pump pulley bolts.
  3. Raise and support the vehicle safely.
  4. Remove the lower splash shield.
  5. Remove the air conditioner compressor drive belt.
  6. Remove the lower alternator cover plate bolts, loosen the alternator adjusting bolt and remove the drive belt.
  7. Remove the crankshaft pulley.
  8. Remove the coolant pump pulley.
  9. Remove the timing belt.
  10. Remove the oil level dipstick and guide tube.
  11. Remove the alternator adjusting bracket from the water pump.
  12. Remove the water pump rubber seals.
  13. Remove the water pump mounting bolts and nuts. Remove the water pump from the vehicle.
To install:
  1. Clean the gasket mating surfaces thoroughly.
  2. Check the water pump by hand for smooth operation. If the pump does not operate smoothly or is noisy, replace it.
  3. Install the pump using a new gasket. Tighten bolts to 115 inch lbs.. (13 Nm).
  4. Install new rubber seals.
  5. Install the upper alternator adjusting bracket and tighten bolt to 17 ft. lbs.. (23 Nm).
  6. Install the oil level dipstick and guide tube.
  7. Install the timing belt.
  8. Install the water pump pulley and leave the bolts hand tight.
  9. Install the crankshaft pulley.
  10. Install the water pump/alternator drive belt.
  11. Install the lower alternator cover plate and tighten bolts to 89 inch lbs.. (10 Nm).
  12. Install the air conditioner compressor drive belt by releasing the tensioner pulley and installing belt.
  13. Install the lower splash shield and lower vehicle.
  14. Tighten water pump pulley mounting bolts to 18 ft. lbs.. (24 Nm).
  15. Adjust the water pump drive belt tension and tighten alternator adjustment bolt to 17 ft. lbs.. (23 Nm).
  16. Install the air cleaner assembly.
  17. Refill the cooling system.
  18. Connect the negative battery cable.
  19. Start the engine and allow it to reach operating temperature. Check for leaks and refill cooling system as necessary.

1991 geo metro engine light came on and it die now won't start motor turn over but won't start


did you try cranking with throttle open 100%
this clears flooding this cuts the injector(s) dead.
does it/
try fresh spark plugs, are the 10 years old?
try test fuel (spray)? run for 3 seconds,
if not, you lost spark check fuses.
if you have spark and it wants flood is the cam belt 10 years old too, if it slips it will not run again, ever.
until that is cured.

97 geo metro replaced fuel pump, has new timing belt, gets spark to plugs will run with ether sprayed in carb but wont stay running, has new water pump, new fuel pump relay, ...someone said check the ECM...


The cam sensor controls the injector pulse. No cam signal = no fuel. Also these cars are known for wires chaffing through on the injector harness. If any of the wires are shorted out it will kill all the injectors and result in a no fuel no start situation. Check the wiring first, normally a no cam signal will set a code and a check engine light. Make sure the fuses are good also. Hope this helps.

New fuel pump not pumping fuel 91geo metro


Check your fuel pressure regulator. Pull out one of the fuel injectors and put it up to a towel, have someone crank the car and see if it sprays fuel. If theres no fuel being sprayed then you know there's something else wrong along those lines.

1992 geo metro 1.0 engine seems to flood and idles high can't adjust idle it's low as it goes and still idles high timing is right on any suggestions?


You might also check the single injector, had a friend's that the fuel pressure regulator had been messed with and was over-pressurizing the injector, that weakened the injector allowing it to flood at idle and also when cut off (the injector was leaking)
