Cranking non start no dash lights and no spark

the tachometer works from the pulse generated for the spark in the ECM or in the ignition control module
the meter is extremely unreliable at cranking speed so at best the needle may flicker at anything under 150 rpms cranking speed
no spark can be from
cam/crank position sensor problems
broken timing belt / chain
ignition control module
ECM
immobilizer
run the fault codes to get an idea of the area of failure

IGNITION SWITCH.

Sounds like a bad starter connection, but it could be any number of things.

You need three things for a car to run - spark, fuel and compression. Confirm you have spark (check the battery for the necessary cranking amps for your car, check to ensure you don't have any fouled plugs/wires), then go from there.

what engine of the many, you cant fix one , unless you know what it is.! (cyl count and displacement works "cc's")
wont start. but cranks fast?????
dash lights up , key on, they all do all cars, its the lamp tests.
perform service, i just can noodle that. what does that mean?

1: check all fuses. in both boxes, EFI needs many fuses to work.
2: if cranks perfectly , does it?
3: we check for spark , in the blind hope compression is good all cyl.
4: spark is good, (and timing in the realm)
5: i then check spark tips, flooded, or dry ?
5a: dry, try test fuel. (spray)
5b; wet, i use supers secret (in opr guide) unflood mode.
"wide open throttle cranking"?
it starts and runs.
it start then stalls and floods again
or it was dry and runs for 3 seconds, test fuel tested.
so you lost injection
if lost, then we check fuel pressure next 30psi min,
cranking, if not 30, we check for 12v at pump, and so on........ask
ask for help if you make it this far.....
takes tools it does.

The sounds wouldn\'t work on that vid but if it keeps cranking check and see if you have spark you can get a spark tester at seats or cheap if you don\'t have spark chances are the actual distributor is bad very common

make sure that you are getting spark and fuel. If you are not getting spark, then you are looking at either a faulty cam, or crankshaft sensor. Check your fuse panel too

Might be your jeep's ecu is bad. Does the check engine light come on your dash, when you turn the ignition key to on, before cranking? If not, the ecu is bad. If the check engine light does come on, it may be the crank sensor is bad on your jeep.

Your timing is the issue, belt or chain is stretched or broken

check inside distributor cap for cracks also rotor arm condition also check crank angle sensor on top of bellhousing also cam sensor mounted near distibutor

hi,seem you have a flat battery,try to charge your battery,fuel pump is ok ,what about fuel pressure,ty
