Why I have no power on 1996 geo metro fuel pump when I try to star it ?

Sep 28, 2014
too old, to post ...? seems not.
check pump voltage at the pump cranking.
then if that fails to be 11v.
then at the fuel pump relay, cranking, (the big pink wire is it)

FI fuses
and ig-coil fuse must be good.
and the CEL lamp glow key on, or ECU may be dead.(ask)
always test with a $10 volt meter,
voltages matter, test lamps were great back in 1950/60.
these cars love to have, like 6 or 8v on the way to the pump, due to rust on the connectors.
the meter shows this truth, and never a lamp.

I have a 2001 honda Santa Fe it got wrecked a couple days ago it no real damage was done besides one headlight busted out but now the car won't start up

Checck see if fitted with a main power lead roll over device. Normaly on the fire wall but can be near battery. If this has been activated some have a buton to press. others are throw away and replace. It kills power to electrics to eliminate possible fire fuel pump etc.

Car keeps cutting off just got a new starter, battery, and alternator

check the battery connections really good and check the power distribution center really good,sometimes the wires will get corroded and cause that too happen,it sounds like you just have a bad connection either to the distribution center or on one of the cables,that will cause what its doing,i own one of those and they will do this sometimes,good luck.

I have a used 1995 Audi A6 that won't start. It seems to be related to the kill switch (I have been having problems with the alarm system as of late). Radio and electric windows work with key in the...

Hi ,im a professional auto electrician and i specialize in car alarms and car audio installations ,its very likely your car alarms causing this as they do have this common problem the world over,its also very difficult to explain how to fix it from only words but here goes !
so first number #1 I would check your car and key ring for a strange short stubby looking chrome key ,that ,if you find it ,can sometimes disarm the alarm on the siren normally located under your bonnet,it (the siren module) will have a rubber door on it that the keyhole is under, if you locate your alarm key try turning this in the siren and try starting your car ,if it cancels your 'ignition kill mode on your alarm "GREAT"then leave it in this mode until you can have a new alarm fitted or just leave it if you dont care to have an alarm, and if you dont have this special key i would then do this #2 replace the tiny battery in the alarm remote control as they can be very intermittant when they are old and failing (you may want to try this 1st) ,failing that here is the main information you will need to know to disconnect the alarm from your ignition permanently but i would only suggest you try this if your at all confident with your wiring skills or advise someone that is of a printout of these instructions .....remove the plastic lower dash covers directly behind your ignition keyhole,this will reveal the ignitionsFAT LARGE wires that start your motor and supply power to your car, there will be one or two of these FAT wires that have been cut and the alarms wires will be joined to them ,you should easily be able to spot these but if its covered in electrical tape you will need to remove it to reveal these ,all you have do when you find these wires that have been changed by the alarms original installer then simply cut them alarm wires away from the FAT original wires and join the FAT original wires of the SAME COLOUR to each other ,this will completely bypass your alarm system ,make sure you join these wires properly with solder and electrical tape or big electrical block wire connectors as they carry lots of electrical power to the cars engine ,you cant shock yourself from these as its only 12volts its just the risk of fire if they touch metal on the car under there ,"note" some better car alarms have another fuel kill on them and if its been hooked up too then you will need to have this removed professionally ok ,i hope this leaves you in a better understanding of the problem you have ,
and THANK YOU for using FixYa

There is no fire going to the fuel pump regulator and no fire coming out of the fuel pump regulator to the fuel pump. What would cause this problem for my 1998 chevy 1500 pick up 6 cylinder engine?

Do you mean electrical current?

If so it means that the fuel pump relay is not getting 12volts from the battery OR it's not sending 12volts to the regulator OR the regulator is stuck in the open position thereby not grounding.

84 CK TRK, 2500, 5.7L 55,000 miles have replaced alternator twice - battery still reads 12 volts. Trickle charge on battery OK and engine starts up OK - terminal 1 on alternator wire (brown) reads 2.4volts...

On some of the older style GM's you can take that brown wire and cut it and take the end leading from the alternator and hook it directly to the hot terminal on the alternator and just leave it hooked up and it will work. But I have ran into the occasional problem where leaving it hooked up will drain the battery when the vehicle isn't running. Hope this helps..

You have no power from the switch to the starter. Check all you wiring that goes through the fire wall and look for burnt connections or just bad connections.

check for blown fuses& make sure the red wire to alt. is getting 12volts. also ford uses fusible links witch look like regular wires. usually you can tell by feeling the wire itself if it feels squishy and when you pull on it it stretches chances are its bad. try an ohm meter at each end no continuity no connection
