Bad ignition control module act


same car as one of mine.
so you change coil packs before spark plugs?
i have the full fsm too, /.7000 pages long..... im scanning now.
you do know this is a wasted spark system so both side can fail, right.
coil pack 1.side runs 2 cylinders. not one.
both spark plugs connected to #1 coil are suspect.
they do not say how the the test is conducted (inane that)
only the useless Burn time , bull.
most times only the possible cause list is a clue to the test.

verbatim. page 4204
MONITOR CONDITIONS
When Monitored:
Engine running and battery voltage greater than 10 volts.
SET CONDITIONS
Set Condition:
If PCM detects that the secondary ignition burn time is incorrect, too short, or not present, an error is
detected. One Trip Fault. Three good trips to turn off the MIL.
POSSIBLE CAUSES
(F342) ASD OUTPUT CIRCUIT
(K19) COIL CONTROL 1 CIRCUIT OPEN
(K19) COIL CONTROL 1 CIRCUIT SHORTED TO GROUND
COIL
POWERTRAIN CONTROL MODULE (PCM)
, then a list of tests to do. in the FSM , get one.


my wild guess is the PCM ,charges the coil for DWELL time
then monitors both the low and the high signals.
if the signal is stuck low, or high this sets.
coil primary.
i think they mean coil charging fails....

94 jeep wont start after trying for long time a few days gose by and it suddenly starts replaced lot of parts still wont start only when it wants to.


Hello and welcome to FixYa!

Have you replaced the coil pack? The coil pack supplies current to the plugs. If the coil pack is faulty it tends not to give current to the plugs. One good reason why it won't run most of the time. I strongly suggest that you replace the coil pack and observe how it goes.

Hope this helps and thank you for using FixYa! Have a good one!

I have a 95 jeep grand 4.0 i dont get any spark yo the coil when i click the key 3 times i get a code 11 and 55 wich is ok if a wait a sec moor my fuel pump relay clicks for 1 min stright then i can...


That clicking sound is caused by the ecu initially not being able to supply enough current to the relays. After a few minutes, the ecu builds up enough of a charge to power all the relays, including the fuel pump relay. If you haven't noticed, the check engine light probably does not light up on your dashboard, until the relay clicking stops. Your Jeep's condition is referred to as the "No Check Engine Light" problem. Your ecu needs to be repaired.

Engine won't start


If you turn the key to ON position and its not cranking at all,then its battery fault.If its cranking but not starting at all.That means the starter is also getting power.So if its cranks but not start then there are few possibilities to be checked.But if its not craning and no noise then battery and starter are to be checked.In other case :----

A jeep that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the jeep. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the jeep starter. The starter gets power from battery to start the jeep. If the starter is faulty then it will not let the jeep to start. Also check and confirm that there is fuel in the jeep. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the jeep. If the jeep starts momentarily, then there's a good chance the fuel pump is not working or the jeep is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

Have 1987 Jeep Cherokee. No spark at the coil and it is a new coil.


Appartently alot of ppl are having this problem; I currently fixing the same problem; I have narrowed it down to a few things; but what was you doing when the jeep shut off? and did it ever start back up later?

No current for the distributing cap for the ignition to start the engine


When you say 'No Current' do you mean no electrical supply. In fact there is vary little current delivered to the central lead of the distributor. The working principle: Low voltage (12 volts) is supplied to the 'coil'. The coil behaves like a transformer in reverse, instead of stepping the voltage down it steps the voltage up. Inside the coil is, as the name suggests, a coil. The primary coil is the low voltage (12v) supplied and consists of just a few windings. The secondary coil consists of very many windings. The ratio of the low number of windings of the primary coil to the large number of windings of the secondary coil is the factor by which the 12 volt supply is stepped up. The coil output consists of very high voltage charge (tens of thousands of volts). This high charge is delivered with negligible current (hence my earlier query). The charge is conveyed by high tension lead to the centre of the distributor. The distributor arm 'distributes' the charge to each cylinder in turn. The charge is so great that it jumps the spark plug gap creating a spark and hence ignites the compressed fuel/air mix. That's the boring bit, to effect a remedy check the low voltage leads to the coil and check that 12volts can be measured on a meter. A bit crude this, but ease the insulation cap back on the central distributor terminal put your finger on it and have someone turn the engine over. A hell of kick up the arm tells you that the high tension side of the coil is working :-). The voltage is so high that it most likely beyond the ability to be measured using a standard volt meter. If not there is 1) a possible short or break in the high tension cable between the coil and distributor or 2) the coil is fried. Either way it is not too expensive to change these. Also check the contact breaker points within the distributor are clean and are of the correct gap setting. An emery board/nail file I find is a convenient and quick way to polish the opposing contact points.

1996 jeep cherokee not starting


The most common cause is usually the crank sensor, but at this point I would not jump to conclusions without testing it as well as all electrical connections pertaining to the ignition system etc anyone can fix a problem by just changing everything but thats not the best way to go!

No spark


I don't think you are interpreting what you are reading correctly.

The ignition coil in a conventional system is supplied with 12 V when the key is turned on and the system modulates the ground side of the coil via a power transistor controlled by a bit of electronics that receives a signal from a pickup coil in the distributor.
If the coil is showing this low voltage, the power transistor in the ignition module has failed and is tying the low side of the coil primary to ground.

Just to make sure, check the current being drawn by the coil primary by putting your meter in series with the 12 V feed.
If your multimeter is equipped as most, it will have a 10 UNfused range.
Do not connect the last lead before tapping it while watching your meter display to ensure it doesn't exceed 10 Amps - it might, and the meter cannot protect itself on that range.

It sounds a lot like the ignition module has failed.
