20 Most Recent 1993 Geo Prizm Questions & Answers

why not just use voltmeter, to check all fuses for hot both sides? key on. (need a video?)_ why not post symptoms then ask a question.? must we send for ever looking for that which doesnt exist.? and did you know there is more than one engine? and both are wired different with different EFI systems?/ 4A or 7A? engine, its a toyota corolla btw. eg: pump pressure is zero. (gages) i check relay, the FP relay is closed. i check the relay input and no 12vd. sure bad fues, is there is one. but on many cars , lots of other things go dead too. with this fuse. ill now guess 4a engine with coin toss. vin code 6, engine, i open glove box. and see the book the opr guide (yes buy one) and turn to fuse page. or login to alldata.com and stop guessing. i look under prizm and corolla, 93 for best clues. (big hint, wink) this EFI has 2 relays, one is the main relay, other is fuel pump the main sends power to the pump relay. so there are 2 fuses, one is marked EFI-Fhtr fuse and IG coil. fuse the main relay drops out of the transmission A/T is not in park or netral. if manual stick car, the clutch switch does the same alldata.com look up your car, your trans, your engine. and see the schematics.

First, buy a battery charger and charge the battery overnight. That should fix it, but possibly only temporarily. It may be time to change the battery, they last 5 to 6 years depending on make and how well looked after. If you do change the battery, use a couple of pieces of wire or jump leads to maintain 12 volts in the vehicle electronics as you swap over..

In the fuel tank there is normally a float connected to the fuel pump with a little mechanism that sends a signal to your cluster telling you your fuel level Test it to see if its functioning

Shift interlock system problem . Not the cable . Your vehicle has a safety system that won't allow the gear selector to be moved from park without the brake pedal pushed . Lock solenoid keeps gear selector from moving . Trying to force it will break something . Do you know how to test electrical circuits with a volt meter ? Here is a web site for free wiring diagrams http://www.bbbind.com/free_tsb.html Enter the vehicle info. Year , make , model and engine size. Under system click on transmission / transaxle , then under subsystem click on shift interlock . Click the search button then the blue link. Park neutral switch , brake switch and the shift interlock solenoid , check electrical circuits .

No it will not.Bit of modification is needed.95 is newer and 93 is older.Its not impossible,but will need some RnD

electrical short in the system somewhere. Thats what is burning alternators. Probably in the charging system circuit.

old post. no photo under hood, no joy. yes, older cars , AC was an option. yes, ac can be added to anything on earth at any time. only cost is matter, mostly nothing is impossible. rare exceptions, ask NASA, they do this all the time. impossible.

old post no engine stated, ?? which one? 4AFE or 7Afe (TOY ENGINE) the harness will not allow cross wiring injectors how did you do that? the #1 injector is on #1 cylinder and on #1 fuel rail port. the #1 cylinder on inline engines, the crank pulley end. if you need wire colors, we can do that too. or log in to mitchells DIY and read. that. here is the 7aFE wires B-O is 12vdc power key on, the ECU fires the 4 on right. end old post day.

NO CRANK 101:sure it can, but so can other things fail....why guess, buy a $10 voltmeter and find it. no?1: check fuse first. and if IMMO cluster light is OUT. (not immoblized by alarm)2: if meter lost, try new starter relay, (wild guess 1:10 chances of a fix.....)3: it can be bad wires bad, connectors, bad PRNDL switch, bad, key switch, IMMOBLIZER ACTIVE, added alarms. added remote start kits, called hacks by me.what's there after 23 long years?what to do....well the steps are all easy in them selves each.1: battery charged,fuses all test good.2: does AAA autotow , jumper method work? jump starting car, with running other car. like all folks do, mostly, and for sure standed on the road.3: did you hot wire the starter solenoid,"?biggn lug to dinky lug? grrrrrgrrrrrrrrr omg the starter and battery are good. is this hard?do so in park (wheels chocked) ok>? the engine will not start doing this hot wire test.a car keys in pocket SURE.4: ok now you know for sure the stater works on the actual car. (we can bench test the too)WORKING ON ACTUAL CAR IS IMPORTANT, TO DIAGNOSIS.5:on this car, a Toyota Corolla in snake GM skinswe then check the voltages at the starter relay.it has 4 pins.2 are coil pins.2 are power contactor pins.we measure them cranking (a live test)how the logic works here varies by "a: what engine is there, unstated.b: what trans, auto or stick>???????c: if car was opted day one with that immoblizer.but we can just test and let the truth win out.lacking facts from you as to driveline actual.Volt meter in hand, DMM set to VOLTS.black lead of meter to battery neg post.here are the relay pins.the concactor relay input pin is 12vdc all the time.it's at battery voltage .the key switch sends 12vdc to the coil pin.there are 4 relay pins in the drawing tell us what to expect.pin 4 is battery voltage 12v if not, fuse blown.as seen in the drawing.pin 3 runs the starter solenoid (now dead)pin 2 is grounded, 0v, cranked, if not ground bador IMMOBLIZER not happy, that P wire is immoin the factory with IMMO added, the ground wire is cut, seen in the drawing.pin 1, saving the fun for last.i check pin 1 , yes, cranking,11v to 12v good, if good, relay is bad.if less than battery voltage or near 0 voltsthat means the KEY Line to the relay is BAD, DEAD.easy no?if the line is dead, here, at pin 1,then the clutch switch is bad, (got a stick shift)or the PRNDL switch is bad, does it crank in Neutral> omg yes?ok lets say pin 2 on the PRNLD switch is dead.that means the ignition switch is bad.but lets move on, to prove that, easy with a $10 meter, no?at the key switch you find the ST1 pin dead. yes, cranked,then move the red test lead to AM1 pin on key switch , its dead.the fuse is blown or bad wring from fuse box to here.all fuses in the drawing left side are 12vdc hot all times, both ends of fuse.if not the fuses or wires are bad.there.http://jeepdied.com/no-crank.html

if the odometer does not stick, watch carefully , the 1/10s digit.drive slow, no bumps when it sticks and watch ODOMeterif odometer dont stick the needle side is, as all do this old.for 90s cars, vast numbers stick and more every dayas owners hedge , gee $200 fix .or more....... get a GPS speedo and use that, or glue on a cell phone holderand use a free app, (GPS speed) to see speed.there you go, all choices.the cable has 2 ends.head end if dead, the speedo and odometer stall.the other end, has gear to trans tail shaft,so it measures actually road wheel RPM and converts that to speed. the cable can be broken on both end or the middle.the bottom end can fail strip out or its gear go bad.fixed them all, every which way but loose.easy no? easypeasy-japaneezeyif the odometer freezes too, that means the cable end is bad.

There is not reset to speak of, please explain what is going on.

im assuming your speaking of the engines internal thermostat ? if this sticks open (not likely) then temp gauge on car will never reach operation temp and stay low on scale ( entire purpose of thermostat in first place) now if your coolant fan switch sticks closed (very likely) then your fan will run constantly and only shut off with the key also another condition that makes them run more often is that engine temp gauge is over normal (showing) and this is an indicator that cooling system has a problem and needs service

check the fan relay for correct operation
