Try metering the wires to the fuel pump first with a voltage meter. If you're getting no voltage whatsoever, locate the fuel relay. Somewhere along the firewall should be at least 2 relays mounted. One of these should be the fuel relay. Meter the wires going in to the fuel relay, the the wires coming out of it. If you have voltage on the wires going to the relay, but not going from the relay to the fuel pump, then you'll have to replace the fuel relay. They're usually inexpensive at most local parts stores--usually never more than $20-25. If you have voltage on both ends of the relay, it's possible that the emergency fuel-cut-off switch has been tripped. You may have to refer to a manual to find the actual location of this switch, but on most vehicles, it's usually in an access panel in the trunk around the wheel-well on the side that your fuel door is on. If it has been tripped, all you have to do is reset the switch (Usually just have to pull the switch out...you'll understand once you locate it. Hopefully this solves your issue.

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 !)

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.

Why won't my 1992 geo prizm fire at all???


1. Though the relay may be clicking test the wires coming into the coil. Use a test light to probe the auxiliary wires if it does not light up, trace the wires and look for a break. If it lights the test light refer to #2.
2. Try to start the engine while testing the wires, if no power coming into coil follow wires to fuse box.
3. If no breaks found on wites look into getting a new PCM

Where is the emergency shut off in a 1995 geo prizm?


All cars, EFI. (some have 3 fuse to operate ECU/spark/ fuel) check em yet?
check power to pump 12v cranking?
no, ? 12v, or 6v? (6v or near is corroded wires /conns)
check power (12v) from fuel pump relay cranking, got 12v there.
if yes , the the path is broken to the rear ) (inertial switch?, not in 95)
if not,12v now, the FP relay is bad or ECU is not turning it on.
if 12v is across the FP relay coil the ECU is working.
if 12v is across this relay, and output is dead, that is a bad relay
or the FI use feeding it is blown.
btw #1 all cars cut fuel (INJ) when spark is detected bad. (ecu)
btw#2 some (software) cut the fuel pump for same reasons.
btw#3, most cars, only activate the FP relay for 3 seconds key on, each time. and some cars only cranking, and running.
all these facts, need to be known to make progress, in EFI.
and more.

Hi,
First check the power connectivity of the fuel injector nozzle, clean it and check if there is dirt on the socket.
Then tell what you see.

Hope that helps you!

1997 Geo Prizm - does not start


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.

1992 Geo Prizm wont start


It could very well be your problem. What you have to do is unwrap the bundle and trace that wire back until you find where it comes from or it stops looking melted part way through the bundle then look at all the other wires close to that spot for burnt spots or insulation worn off and cover them with electrical tape. Cut the burnt wire off and replace it with one the same size,making sure you tape up the splice, and run it back to the engine where it started.
If it goes back to a fuse or switch check them out to make sure they are good. A fuse could have burned out when the wire overheated or a switch could be bad and made it burn. Hope this helps.
