    I scanned my '97 Cherokee 4.0 and got the following message: Ignition coil #1 primary circuit.

    How can I fix this problem? The engine turns on and suddenly stops and won't start again until several minutes attempts.

My 98;jimmy will not start engine turns but will not turn on


check for spark at the plugs then check for fuel. if one of these are missing the car won`t start. common problem on some of these was the ignition module in the distributor and sometimes the pickup coil wires would break. another thing to check is the distributor cap and rotor for damage like a cracked cap or burnt through rotor. fuel pump were also common.

What's your problem? I have a chrysler 300 m 1999. When i go to start it sometimes it just turns over but it wont start. It will start after about ten trys. Then some times when i go to start it up it...


Hey Lindsay!
If you have a dark garage , or some other place you can view the engine compartment in DARK conditions... take the time to go thru these easy diagnostics ;

#1: Open the hood and start the engine while watching the wires and everything in the dark.
Chances are you will see sparks and blue flashes in the spark plug wires and distributor cap area !
Sollution;
Replace wires and plugs and distributor cap and rotor. ( tune up)

I have a 1993 chev pick-up v6 4.3, i just installed new spark plugs,new plug wires, distributor cap and rotor button.All plug wires are back in the right position,and i used the firing order 1-6-5-4-3-2...


This diagram is for 1998-1995 Chevy 6 cylinder 4.3L engines.
Your got the firing order exactly correct, at 1-6-5-4-3-2, but here's the thing to double-check:
The distributor rotation is clockwise (note badly rendered arrow in picture).

Since you probably got everything right, then you're left with really unusual/rare causes of
failure of the ignition system:
(a) rotor button misaligned/failing to make contact?
(b) rotor button not pressed onto distributor shaft far enough therefore failing to provide correct
proximity to distributor cap contacts when coil fires
(c) coil wire or contact loose/disconnected - press coil wire firmly down into distributor cap.
(d) distributor shaft of other damage caused during installation of rotor.
(e) spark plug wires defective from factory
(f) spark plugs defective from factory
(g) battery low - may need a charge to start
(h) ICM (ignition control module) failure - hook up your HEI (high energy ignition) tester, and
watch the quality of the spark on each cylinder.
(i) fuel problem? If spark is being properly delivered, its gotta be a fuel problem...
(j) distributor cap not screwed down flush to top of distributor? maybe just on one side?

Inspect the inside of the distributor cap - if there are lots of little metal bits all over the inside
of the distributor cap, then you know you have a misalignment of some type in there, and the
rotor and cap are destroying each other. normal operation will throw a quota of spark-ed off
metal bits inside the distributor cap, but since your cap is brand new, your attempts to start
the engine should have rotated the distributor so few times, you should see no metal debris.

Inspect the distributor cap contacts to see if any spark marks are more of less in the middle
of the cap's proper "contact zone". If not, you've diagnosed an internal misalignment, which
you know how to correct.

You will need to narrow down your possibilities...do you have spark? do you have fuel going into the engine? Since you mentioned a storm, I'd look at spark first, checking the condition of the ignition wires cap and rotor. Wires should be dry, cap and rotor should not have any carbon tracks between any of the internal contacts and should be dry as well. Check for spark at the plug end of any wire and if none is present, check again at the wire from the coil to the cap at the cap end.
If the engine starts when carb cleaner is sprayed into the throttle body then the problem is on the fuel side, requiring diagnosis in that system.
Most common failures are crank position sensor and fuel pump but before going there, get a manual such as Haynes or Chilton and do tests outlined. Most parts are expensive and difficult to get at...you only want to replace what has failed.

2000 chevy blazer starts sometimes and sometimes not. replaced starter, spark plugs and wires and fuel pump. still same problem. could it be the mass air flow meter? Jackie


Check for spark by removing one of the plug wires from a spark plug and installing one of your old plugs in the removed wire (leave the other end of the wire attached to the cap). Rest the exposed plug on an under-hood surface that will provide a sufficient ground and have some one turn over the engine. You should se a strong blue spark. We have seen some intermittent coil problems on your generation Blazer that would explain a lack of spark. Good luck!

Turns over fine, I replace spark plugs, wire rotor and cap but still fires whenever it want. I performed the secondary spark test and I had no spark. Later I tryed again and starts perfectly. I don't know...


it sounds like your crank positions sensor is going bad, take it out and clean it up and then see if it works, you might have to replace it but try to clean it first.

1997 jeep cherokee 4l will not start on petrol or lpg


Here are a couple of things that could be causing your problem. 1. Bad ignition coil or ignition module 2. Clogged fuel filter 3. Clogged air filter 4. Clogged fuel injectors 5. Bad spark plugs, wires, distributor cap and /or rotor. 6. Broken timing chain/belt. Here are a few things you can try to verify that you have a good spark. 1. Remove the distributor cap and crank the car. If the rotor turned you're ok. If it doesn't turn then that's you're problem and you will probably need to change a timing belt/chain. 2. Check the spark from the ignition coil by pulling the coil wire from the center of the distributor. Use an alligator clip to attach a short wire to the coil wire contact. Bare the other end of this short wire and set it up so it's sitting very close to the engine block. Turn off the lights and try to start the car. You should see a spark jump from this wire to the block. If you don't see a spark it's likely your ignition module or ignition coil is bad. 3. If you have a spark maybe it's not getting to the plugs. You may need to replace the distributor cap and rotor. You can test if the plugs are sparking by pulling one, re-attaching the spark plug wire and seeing if you get a spark when you try to start the engine in the dark. Please note, the metal threads of the spark plug need to be shorted to the engine block to complete the circuit during this test.

No spark


Possibly the crank sensor.

Car starting


There are several problems that can cause this behavior, Is it cold where you are? If so the geo's have a known issue with starting in cold weather.

If not then here is a list of possible issues

1.) Cracked or damaged ignition coil and/or primary wire.
2.) Fuel Pump.
3.) Clogged fuel injectors (Engine will run rough when it does run if this is the case)
4.) Badly worn spark plugs, Spark Plug wires, Distributor cap and/or rotor.

*** WARNING *** Your ignition system contains dangerous voltage levels that could seriously injure or kill anyone coming into contact with the spark. Be sure to use insulated pliers or a spark tester and follow the instructions. Failure to do so could cause serious injury or death.

Tests to confirm:
1.) Purchase a spark tester from your local auto parts store, Connect a spark plug wire to the tester and connect the tester as described in its documentation, Have a friend crank your engine and watch for a bright blue spark, The spark should happen frequently and with a rythm, If it seems to skip alot proceed to test #4. If you dont see a spark at all the ignition coil is to blame, Even if you do see a spark, It should be bright blue and clearly visible in daylight, If it is then your ignition coil is doing its job.

2.) Get a pressure gague and hook it up to the fuel line, Turn the key off and on several times (Dont start the engine) if the pressure doesn't rise when the key is turned to on, Your fuel pump may be faulty, Even if it does rise it should reach 15 PSI, If it doesnt then replace the fuel pump and fuel pressure regulator.
3.) You would have to remove the injectors. I recommend you have a mechanic check to see if this is the problem.
4.) Remove the distributor cap and check the rotor for carbon tracking (A black line on the end that touches the cap) if you see that, Replace the cap and rotor and try test #1 again. If the rotor and cap are in good condition, reinstall them.
