cranking problems

[PAPA35]

New here need HELP. New starter,new battery`s (2), new neutral switch,new wires to starter and checked grounds.Turn key and will start just fine next time just single solenoid click with each turn of key, numerous times then when you think all is lost, turn key cranks and starts. Then, the trouble starts all over again. Please help !!!!!!!!!!!! frustrated. Been stranded too many times. THANKS

It would help to give vehicle information.

If the solenoid clicks and the starter does not spin, then the starter/solenoid may be suspect.

NEW STARTER, OR A REBUILT/REMAN ?????
Parts store reman stuff from far too many sources are junk.


Not uncommon for reman stuff to be DOA..

Have you checked the main battery cables for corrosion and bad connections?
Like it was mentioned the details of the truck would help a bit.How is the starter relay if your truck has one.Some years don't have a relay in the starting system,adding one helps the load on your ignition switch,which could be the culprit.

Sorry, wasn't thinking straight. 94 suburban 2500 6.5 4x4 . runs great when it wants to start. still checking grounds but can't find all. Started this morning then nothing but click, readjusted neutral safety still nothing. Readjusted again started right up. Now again won't start. very limited knowledge of diesels , don't know if even it has starter relay. Remanufactured starter but, was having same problem with old starter that is why changed. Thanks !

Before we dynamite the beast...try this.


Get the RH front wheel off to gain good access to the starter though the rubber wheel house access cover.

Connect a remote starter button unit to the battery lug on the starter and to the solenoid terminal.

You can use a screw driver and simply jumper between the heavy battery lug and the solenoid terminal stud.

See if the starter will actuate...if it does so repeatedly then the issue is likely in the ignition switch (Located on top of the steering column)

Ignition switches do fail.

These switches are a sliding type switch and the contacts wear out.
The starter solenoid pulls a fair amount of amperage and will over time cause the contacts in the switch to burn.

As mentioned about the relay

Add a heavy relay (Ford starter relay) to the starter solenoid circuit to lessen the work load on the switch
