Question about 1991 Geo Prizm

1 Answer

Comes on and then turns off

My dad has a 1991 Geo Prizm which has been sitting in our garage for the past 3 years and has over 100,000 on the odometer. Recently my dad wanted to start it up so he replaced the battery and fuel filter. When he twists the key into the START position, the car turns on but as soon as he lets the key go back into the ON position, the car turns off. What could be the issue?

SOURCE: 1995 Geo Prizm won't start

I just checked the battery connection and what I thought was a good connection wasn't. It need new connectors on the post. Runs fine after I tightened them more.

SOURCE: 97 geo prizm has fire and fuel wont start

check all your relays with an ohmeter to make sure they all operate. A code would go off usually only if it is an electrical problem. If you are getting fuel and fire, and no codes it is most likely a relay. If you did have codes then I would say sensor. So check those relays

SOURCE: My 1990 geo prizm will turn over but won't start.

Being you replaced the fuel pump and that had no effect I would now check if you have spark if theres no spark check your distributor or coil packs if you have coil packs check the crankshaft position sensor that sensor if its bad could cause a no spark condition...

Gear lube where to add

on a 1991 geo prizm auto trans.. differental oil should be put in through the speedometer gear housing. this is the simple way. now i actually put mine in in by reaching behind the driver front wheel and you can see the fill plug "bolt" keep in mind i had a wrench bent for this. mine leaks gear oil and have to add it once a month. anyways, i took about a 1/2 inch tube two and half feet long. with an elboe on it so i could pop it in the hole and fill it. anyone that has a geo prizm 88-93 i think should get this differental oil check or check it. i was on intersate and went from 65 mph to 45 mph very quick. the gears ate the housing up. had to look two weeks to find a trans for it. then found one sitting on the side of the road with a rod through the engine after driving four hours only to find out it was the same way mine was. Has anyone else had this problem?

1991 geo prizm, battery light and brake light in the dash stay lit when you start the car. The car still runs fine just the dash warning lights stay on. The alternator was replaced maybe three years ago,...

Yes, it could be. Or you can check your battery. And try adding brake fluid to your master cylinder. That sometimes will cause the brake light to come on. Or check your emergency brake. Hope this helps, James Booth.

sounds liike a fuel problem, turn key on without starting listen for fuel pump kicking on if it does now check the connections at the pump/fuse if it is kicking on the you can check the fuel pressure by checking the little valve on the fuel rail next to the intake looks just like the air valve on your tires if there is no pressure then check fuel filter.
