Can i as symptoms before all those parts changed/???????
working with out a schematic, kinda stinks, no?
this IS not a no start ,sorry its NO CRANK
is car auto or stick, both are wired different.

see the steps here.
i dont have liberty books, (dont like this car)

replaced key switch, surely not, you that is not possible if car
has SKIN IMMO system. not at home, not DIY
if you , damage SKIM, LATER WHEN CRANKING WORKS
nowwill never start. ever. (immoblized )

to crank the engine on jeeps, the start relay closes
what closes that , answer the transmission park neutral switch
try cranking in neutral yet, bingo>

no cranks are easy , see below.
no starts, vastly more complex
most these cars use permissive, start relay
the trans gives this permissive so drivers can start in gear.
and run over muffy (safety)

https://www.jeepdied.com/no-crank.html


to fix cars like this
go to mitchells (online) google it. all shops have this....
or
here,, on CD, and book.
https://www.techauthority.com/en-us/products/81-370-05060CD

if you scanned the PCM with any scan tool
cranking, guess what, it would have errors called
this is 2005 Grand cherrokee,
see this simple drawing.
pin 30 realy must be 12v, if not fuse 10 blown or
main fuse. fronting it.
pin 86 is 12v in park and neutral, if not
p/n switch bad or loss of 12v to said switch.
pin 87 is GOAL, 12v here cranks starter.
last it that pesky 85
this is the PCM, logic
0vdc here, energizes start relay
now the bad news. if all voltage pass but 85, stuck at 12v, (circle 'A")
then you must scan the PCM to find out why
it has good reasons. and will tell you.
i can name 3 but ive not clue as to the options on car , like for example remote starting option.
etc.

    I replaced key or switch?
    this part blows me away
    the key is new
    or
    the key switch is new. (if yes,is it a SKIM car with Immobolizer?

My ford escape wont start no bells no whistles but battery is strong only the air bvag light on the dash comes on


Turning the key to on, no warning lights or dash gauges come on? That sounds like the ignition switch is not working, or power is not getting to the switch. Power for the switch would likely come from a maxi fuse under the hood. So check all your fuses as a start. If fuses are good, one will have to check the ignition switch for power in and power out, when key is turned to on. Use a test light, pull the ignition switch electrical connector apart. On the harness side of the connector, probe all the terminals in the connector. One wire should be the hot wire to the switch-hot at all times-just waiting for the switch to send power out to make things work. If you have a hot wire there, plug connector together, turn key to on, and backprobe the electrical connector, looking for power out on the run wire. The start wire (going to the starter solenoid) will have power when key is held in start. Too many wires? Confused? Keep probing-all you looking for is power in on one wire, and power out on one or maybe two wires with key on. If no power out, the switch must be bad. If no power in, the electrical distribution system will have to be checked-back to the power distribution center under the hood where the maxi fuses are.
Post back if not clear, or if you need more help. Always appreciate a reply. Good luck.

I think your ignition switch has quit working, or it has stopped getting power. If you pull the connector apart to the ignition switch and check if there is one wire on the harness side of the connector that has power, it sure looks like a bad ignition switch. One fat wire, about 12 gauge size, going into the switch should be hot at all times. If you have it, pretty obvious that power is not going out of the switch. key on should send power out of the switch to the fuses for the windows and other accessories, and also send power to the dash for the warning lights and gauges.
Power to the switch will be either from one of your fusible links near the battery or from a maxi fuse in the fuse/relay block under the hood. The funny action of the key kind of points to the ignition switch, though. Still, check for power into the switch first.

Replaced starter and ignition relays under hood on my 99 chevy silverado and to wont do anything no security light no nothing is on everything good on all connections replaced wiring harness...


Is power getting to the ignition switch? Do the warning lights and gauges come on when key is turned to on? That would verify power in and power out at the switch. Then you would need to check the start circuit. A single start wire comes out of the switch, the signal travels through the neutral safety switch and a starter relay and then to the starter solenoid mounted on the starter. Solenoid closes contacts so battery power can operate the starter. If new starter doesn't work, power has been lost between the ignition switch and the starter.
If no power to the ignition switch check maxi fuses, all fuses in fact, and possibly a fusible link from the battery that may be the feed for the switch.

Why wont my 93 honda civic ex start and run and come out of park


You have to have power to the brake switch and the key switch to release the park solenoid.
There is an 80amp fuse and a 50amp fuse that powers the key switch.
Have you checked them to see if they have power ?

Check for voltage on the purple wire at the starter when turning the key to START. If no power, check for power at the purple wire coming out of the neutral switch/clutch switch. If no power, check for power coming into switch on yellow wire. If no power, check for power on yellow wire at ign switch. If no power, check for power coming into IGN switch on red wire. If no power, you've got a blown fusible link.

A REASON WHY THE ABS LIGHT IS ON BECAUSE YOUR ANTI-LOCK BREAK SYSTEM NEEDS REPAIR OR IT COULD BE THAT THE LIGHT ISNT WORKING PROPERLY,,,, AS FAR AS THE NO HEATER AND NO POWER TO THE WINDOWS, I RECOMMEND YOU CHECKING YOUR FUSES, IT COULD BE A BLOWN OUT FUSE, IF THAT DOESNT WORK IT COULD BE A ELECTRICAL PROBLEM I RECOMMEND YOU TAKING IT TO A MECHANIC,, IF THAT AINT THE PROBLEM THAN ITS THE MAIN COMPUTER THAT NEED TO BE CHECKED..

2006 Jeep Wrangler won't start


First, make sure you can turn the engine by hand. If you can't then the starter can't turn it either. Have someone else turn the key and look for the source of the click...may be a relay. Go over the starting circuit with a volt meter. Check for power at the starter main terminal and then with the key turned to "start" check for power at the trigger terminal on the starter. Check battery voltage and check relay operation.
You have a neutral safety switch on the transmission if its an automatic and a clutch switch if it's a stick. Check them as well. Make sure battery grounding on fender and block are also clean and secure.

Turn key no warning lights come on but headlights work etc.


Yes. the starter is malfunction at this time. it could also be a ignition issue as well. here is a quick starter test procedure that will help you troubleshoot a bit.



Step 1
Check for 12 volts on the large wire attached to the top terminal on the starter relay. It should have battery voltage. If not, the battery, terminals or wire is bad.


Step 2
Check the small wire on the solenoid for power when the key is in the start position. Remove the small wire on the solenoid and have a helper hold the key in the start position. Check the wire for battery voltage. If there is voltage, the starter is bad. If there is no voltage, replace the wire.


Step 3
Check the fuse in the fuse box under the hood on the left fender well. If it is good, check the relay by pulling it out and checking for power at one terminal with the key off. If there is no power, the problem is in the fuse box between the fuse and the relay. If there is power, have the helper hold the key in the start position once again and check for power at another terminal from the ignition key. If there is power, the relay is bad. If there is no power, the starter circuit is suspect.


Step 4
Check to see if there is power to the neutral safety switch if there is no power at the relay. Use the voltmeter to check for power with the key in start. If there is power going in, check for power going out. If there is no power going in, the security system or ignition switch is suspect. If there is power going in and none coming out, the switch is bad. If there is power coming out, the problem is between the neutral switch and the relay.


Step 5
Remove the cover on the bottom of the steering column. Check the solid yellow wire for power when the key is in the start position. If there is no power, the ignition switch is bad.

You need to establish that you have 12v in the battery and that all connections are clean and secure. Lights horn etc do not give you voltage verification...your starter uses more amperage than anything else in the car. Once you are certain that everything is OK, check for 12v at the small wire on the starter with the key turned to start. If no volts, check the neutral safety switch or clutch switch Then check ignition switch for power in/out.
