Try having someone turn the key to the start position while you tap on the starter it may be jammed or you might check for misallignment of the starter and make sure it is wired right.

1993 Geo Prizm starter clicks & does not crank. Battery & Starter tested good & engine not seized. Could this be neutral safety switch? If so, how can I bypass or test it.


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 skins
we 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 bad
or IMMOBLIZER not happy, that P wire is immo
in 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 volts
that 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.

How do I check a ground connection ? My 1988 GMC Jimmy has a new starter and again it seems to free wheel and not start.Seems to help if I put it in neutral.


You could possibly have a bad park neutral safety switch , power ( voltage ) from ignition goes thru the park neutral safety switch to the S terminal on the starter solenoid . Does your vehicle have automatic or manual transmission ? And you should have voltage drop testing on the starter circuit done . Starter Voltage Drop You could have a bad battery cable .

99 tahoe wont crank wont start with new battery


Does starter click? Try turning on headlamps and get someone to watch as you try to start car. If headlamps dim, likely bad starter or battery cable(s). If they don't dim, bad solenoid, starter switch, neutral safety switch. Try starting in neutral and jiggle shifter while trying. If it starts, replace neutral safety switch.

How to fixed wont start engine..


test the following and fix it. GOD BLESS you.fe35589e-c7d2-4fa3-a813-99841956a6cb.gif
If nothing happens when you turn the ignition key to the "Start" position, it means that the starter motor doesn't turn over the engine. Most commonly this could be caused by a dead battery;
If the battery checks out OK, but the starter still won't crank, there could be a number of possible reasons. Here are some of them:

The ignition switch could be bad - it's a common problem. An ignition switch is an electrical switch installed at the back of the ignition lock mechanism. If jiggling the key in the ignition helps start the car, the ignition switch should be checked first.
The starter solenoid control wire could have a bad connection.
The starter motor itself or a starter solenoid could be bad.
A neutral safety switch is bad. If a car doesn't start with the transmission in Park, but starts in Neutral, it could be caused by a problem with a neutral safety switch.
.
A problem with vehicle's security system or some other electronic control module (e.g., ECM, BCM) may also prevent the starter from operating.

1998 chevy asto van wont crank or turn over


Turn the headlights on and watch them while the key is turned to start. If the lights go out, one of your cables or connections at battery or starter is not good. If lights dim a lot but stay on, possibly a bad starter, it needs testing. If lights aren't affected by cranking position, turn lights off, pull the small wire off the starter solenoid, hook up a test light to ground and to the solenoid wire. Light should come on when key is held in crank. If it does, likely a bad starter solenoid. If no light, then the start circuit from ignition switch to starter solenoid is not working. Check for power out of ignition switch on the start wire with key in crank, to begin with. If powered, switch is good, need to check if neutral safety switch is good, and then check or swap in a new starter relay.
Post back with any results.
Good luck.

Car only starts sometimes


The start circuit from the ignition switch to neutral safety switch to the solenoid on the starter might be bad. Look for power there at solenoid or at neutral safety switch when it doesn't want to crank over.

1986 camaro v8 tunedport will not start wipers lights etc work brand new battery.i get no crank at all. neutral safty switch mabe??what do you think????


if you use a test light and check for voltage on the big wire at the starter this will tell you that the wiring from the battery to the starter is good.now check the small wire at the starter while someone tries to start the car you should have power to that wire.if you do then the wiring from the ignition switch to the starter terminal and everything in between is good.the problem is the starter solenoid or the starter.its a good idea to replace the starter as a new solenoid comes with it as apposed to changing only the solenoid and the starter goes bad shortly after.if you don`t have power to the terminal then check the neutral safety switch.

Switch rotates all the way to starting position but does not engage the starter. Battery is fully charged.


you could have a bad fusible link or a broken wire to the starter or a bad starter or a bad neutral safety switch check for power at the starter with the key in start position if no power bad fusible link if power then check solenoid in starter if the solenoid is good then id have to say neutral safety switch
