Is the starter relay bad if the battery is good but nothing happens when you turn the key, when i jump starter with key on sylenoid just spins and doesnt engage
if the starter motor spins, and engine crank shaft fails to spin
that is the soldnoid pinion shaft jam up, there is no bendix drives since 60s , it's solenoid drive not bendix. (apples and oranges diffr)
it sounds (im pretending i can hear it. and cant ( but of the starter (yes it is a motor) spins, fast and not the crank the pinion is not engaging the fly wheel teeth.
time for a new starter or if time is no issue buy a new solenoid.
First the starter is bad. It spins but doesn't engage. Second if you can't get the starter to turn with the key, look at fuses. Then security issues.
Try this procedure:
Check the battery like this:
Turn on the headlights, then try to start the car.
If the headlights do not dim or go out, then the battery is likely ok.
Check that the battery cable plus post, goes to the starter, Minus post to a good ground, like the engine.
If wiring is ok, then look at the starter solenoid for a good connection, and proper voltage at the starter.
Problem is most likely the Solenoid's bendix gear or starting relay, Have someone bang on the starter while you try to start the car. This usually works by dislodging the bendix gear..
Hope this helps.
I cant dope out that symptoms.
does it crank or not. be clear there.
no car starts (but my 6sp) if it dont crank.
on A/T cars cranking is a first thing. so does it.?
Solenoids do not spin, the stroke only , it a linear motion.
the Sol. moves the pinion and the main contactor switch only.
my guess is the Starter spins and the crank don\'t spin,
you hear the starter motor spin up, it sings. like bird.
that means the starter /solenoid are bad. (crude)
if the battery is good and or jumper starting off a running car.
It can just be a dirty starter pinion, clean it , repeat.
fixed many for this. i have.
battery cable lugs clean, and good. no green rust.
bad cable usually just make a loud THUNK sound. no spin.
SOURCE: WOnt run over - battery good - can turn it over but jumping the starter
if the battery is good and you jump the starter she should run otherwise you may have a sensor issue, try to get a hold of a code reader and see if any codes have popped up..
SOURCE: wont start, new battery, relay good, starter good.
Check the Starter Solenoid mounted near the battery.Check it out in the dark...have someone try to start it and see if it sparks at the solenoid.connections may be loose.Also check/wiggle wiring harness to starter.
SOURCE: will not crank turn key
Check fuse # 28 (15 Amp) with a test light. (Located in the Power Distribution Center (PDC) on the left side of the engine compartment) It should have power only when the ignition switch is turned to the START position. If there is no power there, then you probably have a bad ignition switch. The only other fuse involved would be fuse #8 (40 Amp) which is also in the PDC. If this fuse is blown a whole lot of stuff is not going to work - not just your starter. The starter motor relay (Also in the PDC) is controlled by the PowertrainControl Module. The wiring diagrams show it as a 5 pin relay whereonly 4 of the pins are used. If you check for power and ground at the connector pins for the relay, there should be one pin that is hot all the time. This is the power from fuse #8. a second pin should be hot with the key in the RUN and START positions. This would be the circuit running through fuse# 28. One pin should have continuity to ground (your test light should light up if you hook it to the battery positive terminal and probe this terminal.) This is the circuit that goes down to the starter. The 4th pin will have no continuity to anything at all until the ignition is placed in the START position, when it will have continuity to ground. This is the relay control circuit from the PCM.
If you dont have power at the relay connector as described, then you must repair the circuits between the fuses and the relay. If you don't have the grounds as describedfor the starter circuit, you ether have an open circuit going to the starter or a bad starter. If you are not getting ground on the control circuit from the PCM, it could be several other things causing your no-crank problem. It could be an open circuit between the starter relay and the PCM or it could be that the PCM is not allowing an engine start for one reason or another - The PCM will have to be scanned to find out what the problem is.
