Battery,good new alternator starter good new grnd and hot cable when you turn switch to crank wont do anything tried to jump start still nothing could it be a bad starter relay or what

It won't crank? Have you tried rapping the starter with a hammer-a light tap- to see if it will work? If that works, the starter is going out and needs replaced. Alternatively, take the starter off and have it tested for free at a parts store.

make sure is ither neutral N or P. it looks like you have en electrical problem check ing. switch check for a blown fuse.

no CRANK
the first test. is jumper cable cranks.
the lights only use 1/50th the current of a starter, and dont prove anything. (eg. bad batteries do run lights great, can prove.)

juimp start it,
good, yes. bad battery; battery dischanged,or bad charging system
or left on the lights. too long.
bad jump, this means the cranking system is bad.
bad crank.
1: cables from battery to starter, corroded.
2: bad cables. split open and green copper everywhere.
3: I hot wire the stater solenoid, if fails (good battery and cables )
then it is a bad starter, (i hit it with a hammer, and bam it cranks
great tick to get of of big time trouble , far off grid or? danger zones...

4: hot wire fails.
bad KEY line.
if key oine fails wiggle the A/T shift handle, cranks now?
try neutral cranking, (fresher contacts here, magic happens)

IF a stick shift car nows the time.....

ask how to hot wire or look here.
see test 1 here "hot wiring techniques"

I have M/T and park on hills and start by rolling starts.
i dont need a good battery, in my 1968 xxxxx (1/2 joking)

The most common cause of a non-starting car is the battery. It is either weak, (low voltage) dead, (zero voltage) or has bad connections. (corroded or loose) I will assume you have a fully charged battery with good connections. (both to battery and starter relay) Just becaue its new, don't mean its good or fully charged.

If you remove the starter switch lead (small wire) from the starter relay and apply +12v from the battery to its respective prong or lead on the relay, and your starter cranks, your starter switch is faulty. (not to be confused with your key switch). If you jump the two large wires together on the relay and it cranks, then the relay is faulty. If you jump the two large wires together and nothing happens, then starter is faulty, or wires to starter are loose or broken. Picture of starter switch prong on the relay is pictured. NOTE: sparks are to be expected, so don't be too scared.

what transmission,?
this can be 3 things, if it wont jump and batter is good.
bad connections at battery or starter.
1: bad starter.
2: bad (A/T shift switch) or bad M/T clutch switch.
3 bad ignition switch.
4: bad wire or connections end to and start system.

hot wire the starter solenoid, if car starts (cranks) then its 2 o 3.

wont crank or wont start.??
no car starts , if it cant crank. (unless push starter (M/T magic)
that is not a trans sensor its the PRN switch.
ill answer for, wont CRANK !
it wont crank even with a good battery (charged) or jump started.
1: bad start
2: bad wires to same.
so hot wire the starter small wire, the key start line is tiny.
cranks. , starter good, no crank starter bad or cables bad.
if it cranks hot wired, then the key line is dead.
easy, huh?

Could be the cables or the starter. Remove the starter and have it tested.

Bad solenoid i would guess. Not making a connection there. Any basic wiring and ignition switch problems should be alleviated by jumping the starter with a screwdriver. I would check the solenoid and starter brushes

If you banged on the starter motor and it started then you have a stickie bendix drive and solinoid sticking
But if you have to also jump start it as well then do this.....When it wont start before doing anything else turn on the lights and hit the starter and if the lights go dim or go out the battery is no good or you have a short in the eletc ...so take battery lead off for 2 days and if starts you have a SHORTin the eletrics

You should have you altenator checked most local parts stores will do it for free
