Question about 1995 Geo Prizm

1 Answer

Fuel pump problem

Sirs,
I just replaced the fuel pump in my 1995 geo prizm because the old one wasn't running. New one doesn't run either; what do I do now?
Is there a fuse or sending unit relay switch or anything of that order that I am missing?
I am thanking you in advance for any and all help you can give to me,

    No, I didn't.

    But, since i installed a new pump and it doesn't work, isn't it safe to assume that there isn't any popwer going to the pump.? you can bet that I will test it now, however!

Did you check voltage to the pump before you replaced it and did it have voltage then?

    First of all, make sure you have good ground from the pump to ground, use an ohm
    meter. If ground is good then get
    a good schematic for the car and that
    specific year. The wire from the ECU to the relay can be easily checked with an
    ohm meter, if that wire is OK then disconnect the positive post on the battery.
    Get access to the ECM, disconnect the connections from the ECM one at a time,
    and plug them in. Now, hook up the battery and try starting again.

    Good
    luck,

Where are the fuel injectors located on a 1995 geo prizm


are you dealing with a no start or with a poorly running engine? if it runs very poorly and shaky when cold but then improves as it warms up, it could have clogged injectors. if it's not starting, then I doubt that clogged injectors could be the cause; more likely it would be that they aren't getting juice at all.

95 geo prizm wont start


wont crank or will not start.? 2 unique things. no crank always results in , no start (unless you push start the car)
hot wiring the fuel pump relay or any relay in the EFI system , invites
blowing the ECU to kingdom come, bad to the bone that.
I fixed them for 50 years. (electronics controls, so know it !)
you do know its really a toyota right?
what ENGINE? each works different.
my prizm text dump.
89-02
joint venture, GM/toyota with 3 engine used.
1.8L or 1.6L
toy engine, 4aFE, 7AFE or 4AG
open hood look
or use the GM RPO tag
or Use the VIN to find motor used.
for docs?

does car start with test fuel and run, until the fuel runs out.
do you have fuel pressure, while reading the FSM , way of doing it.
some cars only make fuel pressure, cranking and runing.
other make pressure, for 3 seconds key on, and cranking and running only, and all cars drop pump and injections when ECU sees spark die.
that is why stating which Toyota engine YOU HAVE, helps with diagnosis. and please stop hot wiring your car and learn to use a voltmeter. Ive seen $3000 ECU blown up do to bad mechanics.

1995 geo prizm hesitates in summer not winter


My first guess would be lack of fuel. Did you check fuel pressure after replacing the pump ? Did you also replace the fuel filter ?
Is the check engine light on when the engine is running ?
There is a long list of choices.

Have 95 geo prizm with no fuel pump relays and fuses are good. when i jump the relay i can hear the pump work.. is there any other sensors that would cause the pump not to work


The oil pressure sending unit will stop the pump from running. This cuts the car off if it senses no oil pressure. Same sensor that gives you the pressure reading or the dummy light.

I need location of a 1995 Geo Prizm 1.8 fuel pump relay


I think it is under your rear seat cushion. Remove the rear seat cushion, you'll see the gas tank cover.
