Hi Rita, are there any warning lights on the dash? How long does it run for. starting and running for a second or two would indicate an immobilizer fault and that the key has lost its code with the car That would need to go to a garage. Jon

if any code turns on a fault (engine light) then the remote won't start the jeep, factory set. read to see if any codes set or any warning lght on

Good news! Jesus is coming.
More good news: All that is wrong with your car are the tiny wires coming off the distributor. They have broken into from years of vibration. They look fine for the insulation is intact. (Once the car starts, it switches from battery power to altenater power). Repair the wires and your car will run.

Isince it cranks, means you have power, elctric system is ok! I guess.. this could be a result of gas delivery problem... either a pump or gas circuit controller.... OR a small propable reason if you have an immobilizer (electronic chip on key!)... but there should be the securit key highlithed on dashboard...

Well first it should only restart in park or nuetral, any check engine light on? May be fuel pump if not. Listen for pump running in fuel tank. Should run at key on for a few seconds. If check engine light on, it should be scanned for codes, possible crank sensor

ignition switches are common problems for this model

Ok if you have a check engine light on then you need to have a computerised diagnostic on the car..which will give you an error code...

times the starter will continue to run until key is turned off.
that is starter relay bad or the puter running it gone nuts.
or bad starter
next time when starter latches up, pull the relay
if it kills the cranking its bad relay or puter
if not, bad starter. all in 1min work..
and a very very serious first ORDER fix first problem
runs on test fuel. but you failed to keep it running for the 2 -3 second JEEP RULE.
if you had here is the results. (logic) hard.
1: i can keep it running with spray need a video?
yes, means ASD is not dropping out
2: no? ASD is killing the engine on purpose. and scan tool told you.

cranks no start
you said,
"No codes." if really true , there is no fuel pressure.!
if not true, its done wrong. so scan correctly THIS time.
is the skim light glowing in the dash cluster, if yes, it will not start
by DESIGN. SKIM is the immobilizer and DOES!

you must scan WHILE l its failing, not after, WHILE.
HOW TO SCAN correctly on JEEPS, (no starts)
key on, see scanner working? now, it must, if not ask.
crank or 5 seconds, (1 potato , 2 potata, 3,4,5.
release key, ( 4 and 5 are overkill but why not?)
do not turn key off or say 2 minutes, get PCM time to REPORT.

scan (2008 or newer scan tools work, CAN-BUS certified)
the tool then tells you why the ASD RELAY dropped killing starting (by DESIGN)
try to know SKIM is and option, so.... me blind can see car
http://jeepdied.com/ASD.html

runs on test fuel longer that 3 seconds, by hand, means.
all is working mostly, the fuel pressure gauge needs a jeep hose kit to work so/....... the pump needs power to work,



now the acid tests
i have 2. acid tests lacking a real scan too;..
spark timing light connected up.
you crank and spark dies, AFTER 2-3 seconds into crank/start
cycle means ASD dropped.
connect meter to injector 12vdc power feed its a daisy chain
12vdc dies, at 3seconds of crank, or dies
at 3 seconds of running,
if true PCM did that , and is ASD drop doing that
running any jeep for 1 second on test fuel is a waste of time
it tells too little
learn that jeeps can drop a ASD at 100mph
any time it wants. and only scanning while it drops
tells you why, unless the SKIM lamp glows,

Sounds like passlock security failure.Park neatral swith located at top af transmission where shifter cable connects to trans,should be on drivers side.
