Question about 2005 Jeep Wrangler

1 Answer

04 jeep wrangler hard to start, runs fine when running.

You have to turn key over 2 or 3 times before it will start if it has been 20 minutes or so since running.

im thinking i have a fuel delivery problem.
runs fine when its running. it is a 4 litre engine with 60,000 miles.

    I have the same problem with mine! I have to turn the key 2-3 times before it starts, then when it does, and I put it in gear it has a miss, but goes away shortly after. I changed the plugs, new dributor and cap, and new fuel pump! What the hell is wrong!?!?! Anyone have any ideas?? Please help, this is getting expensive.

Does it have a vacuum controlled fuel pressure regulator, if so check it for leaks into the intake. Also check fuel pressure

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,

No spark from ignition module on hot start


95 JEEP WRANGLER 4 CYL

No spark. I have changed out the distributor cap, rotor, wiring from coil to cap, and coil was replaced. I checked the distibutor by turning ignition key and observing the rotor turn. What else can I check. I did not observe a module.

89 wrangler get warm won't idle the takes along time to restart


These jeeps are carbeurated, with heavy emissions systems forced down the throats of Jeep. There are insane Vacuum systems that are too complex to deal with. What I did, (I have the 4.2L) was go out and purchase the Weber kit. I am not selling the part for them, I am actually a happy owner. Mine would die every time I came to a stop. I swapped out the junk and popped in the Weber. I have had no carb problems what so ever. I even eliminated the messy vacuum system! I payed about 200 bucks on Ebay, but from Weber direct they cost around 300. Good luck!
