94 jeep has no spark at spark plug


94 GC ZJ body.
which engine option?
says you have no spark
so you read the fsm. on that.
on spark an fueling and the ASD relay.
no gas car runs with no spark and jeep cuts fuel if no spark is MONITORED as true, by ECU.

what a shop does,
is scan it , if no scan tool
he, uses one of the other 2 ways scan,called the blinking light deal.
i crank for 5seconds, and see if it stores, code, 11 or others.
click ZJ
click emmission
see chapter 25 on how to do flash CEL check engine tests.
the ECU will tell you if crank, cam senors are dead or they they are not dead but spark is.
if the ecu see any of those 3 errors, it cuts the ASD relay in 3seconds.


http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

it take 2 people to do this.
person one keys start. and sees ASD close for 2seconds.
you key fast and person looks for spark
if no spark that means the ASD didnt close
1: if cam and crank DTCs didnt happen then its spark bad.
2: cam/and crank sensor pass. then no spark that means
the ignitor is dead or coil.
check spark at coil not spark plugs.... for better way.

why people get so confused here is that there is only 2 seconds
to see spark..
let me give a prime example here: (shows the ropes)
person 2 saw spark for 2 seconds, but the ECU saw the CKP crank sensor misfiring 1 out of 10 times. the ECU considers this bad
and cuts the ASD , killing ALL, and setting CKP dtc error
fix bad CKP.
see?
all 3 tests must pass or the ECU will cut the ASD.
the asd kills spark and fuel.
not just fuel.
tricky yes, but no crash and burn like seen on TV.

im not sure but this ECU might store all DTCs found cranking
some cars dont. store bad spark. only CKP and CMP bad.
the ECU does see the spark singles bouncing back from the ignition coil primary, if missing it cuts ALL>

No electricity spark plugs 4,00 liter


check all fuses first, every time, something fails EFI.
the scan tool will tell you why 90 % of time.
connect scan tool
key on
crank for 5 seconds, see scan tool show 300 RPM? about.
good, no RPM is bad sensor (Cmp or ckp)
release key , do not turn off yet
see DTCs stored, now, bingo, its telling you what is bad. OMG.
p0340/ 355? and the like? are bad CMP, bad CKP, or others get em
post em or look them up in the FSM. or at alldata.com
Theory:
the ECU creates spark
there are the 2 sensors that tell the ECU when to spark (inputs)
and the ECU DRIVER the ignition IGNOTOR, that runs the ignition coil.
1 coil or 6 coils. depends on year.
4.0L I6 Jeep engines.


did you check for spark directly at the 1 coil car or at all 6 coils for 6 cop coil cars?

cops are coil over park plug, i think your car is 1 coil, had a 99 jeep.
and this old six still had one, coil, so does this one coil make spark
to a test spark plug, Y/N
if yes, the dizzy cap is bad or wired wrong. to plugs.
I no spark here, do the DTC scans above.!!!!!
post back results.

2001 jeep grand chorkee long crank times replaced crank sensor cam sensor and fuel pump cold starts only 4.7 engine


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

1994 Jeep Grand Cherokee, 318 V-8 it has been hard to start on several differant days. Other times it would die and restart after setting. Noiw it cranks over but will not fire. It has 40 PSi of fuel...


Sounds like the ecu on your jeep is not powering up all the relays properly, allowing spark. Have the ecu checked to see if the capacitors, which regulate power to the main relays, are dead and need to be replaced.

Jeep died while driving. Wont start. Garage said they couldnt communicate with the computer. I replaced the computer and coil. I am getting no spark. I tried the turn on / off/ on /off / on to get the...


Check the ecm fuses if they can't communicate using an obd reader then the ecu isn't getting any power different car company's label them differently but look for the ones that are labeled something like ecu, ecm, engine controller, or something like that I hope this helps

98 jeep cherokee wont start it is not getting fuel changed the fuel pump rotor distributor cap spark plugs coil and it still will not get fuel.


i just had the same problem on a 1997 4.0 . crank sensor is most likely bad you can spray starting fluid in the intake tube and car will start meaning you have spark but injectors will have no power I.E. crank sensor is bad 38.00 dollars at local parts store dealer told me 170.00 dollars make sure you push it all the way in when you install it i just posted a fix for this on this site today . after you start the car if it gives a misfire code and check engine light comes on loosen the crank sensor bolt and push it in again then tighten the bolt the cardboard on the sensor for the air gap wares off a little bit enabling you to push the sensor in a little bit more misfire should be gone there is only a few thousands of an inch adjustment for the air gap and it makes a difference. hope this helps
