Placement of crt coils on HCN653W

I removed one crt at a time to replace coolant, marked coil positions with silver pencil, cleaning removed pencil marks, so I used nest tube as reference, did this with all three crt's, now nothing aligns, colors are tilted away from each other and above or below each other, repair manual alignment procedure with remote won't line them up, so I suspect coil placement is problem.

thanks

Unless you are real good at this you will be treading on thin ice you always have 1 as a reference
you replace or service 2 tubes then realign them to the reference once done you replace the third and align to the first 2. you never need to replace the coolant and it is only a job for an expert as a bad seal here will cause the coolant to leak out onto the neck and then down to the crt socket.. this will short out the high voltage and your troubles will have just begun. you will need to realign this from scratch now.

How to clean a distributor


This must be an older car as most newer models use direct ignition, coil pacs and cam sensors . To clean an older distributor remove ignition plug wires (be sure to label them so you put them back on the correct terminals). Remove cap and check for pitting and burning of contacts on the inside. you can use emery paper to clean light pitting. If badly pitted replace cap. do the same for the rotor the rotor may need to be replaced and is cheap. Wipe out any carbon on the cap. Check tiny wires that attach to ignition module inside distributor body for wear also the pick-up coil. Be very careful as they are fragile and easily broken. If you want to remove the whole distributor assembly . You need to mark the position of the shaft of the rotor to the engine with a white grease pencil so you return it to the exact position. Remove retaing clamp and pull distributor assembly straight up from the engiine block. be careful as there may be a washer or pin in between. Clean with solvent on the bottom grease and return to original positon. Reassemble in reverse order.

How to remove distributor on 1984 monte carlo 305 v8


bring engine to top dead center #1 with the timing marks. remove distributer cap and note position of rotor direction and mark on the distributor housing were the rotor is pointing. also mark the position of the distributor mark to a position on the motor, then unbolt the distributor holding bolt and remove. pull up on the distributor and note which way the rotor moves as you pull the distributor out. again mark where the rotor is pointing when the distributor is out. the reason for the marking of rotor position and distributor position is so when you reassemble you line up the marks to get it into the proper position when the distributor is back in place. then you have to check the timing and set. as far as the pickup coil remove the distributor gear lock pin remove the gear and remove the distributor shaft to replace the coil. reassemble in reverse order.

How to remove the pick-up coil from the distributor. 1989 GMC 1500 4X4


The distributor does have to be removed and dis-assembled in order to replace the ignition pick-up coil/stator, and if the pick-up coil/stator is faulty then the distributor should be replaced because the distributor will come with a new pick-up coil/stator and the old distributor will have to be removed anyway and in the long run it will actually save money from not having to pay a mechanic to remove and dis-assemble the distributor to replace the pick-up coil/stator, however most of the time it is the ignition module inside of the distributor that is faulty.




When the engine is at TDC (Top Dead Center) is the ignition rotor pointing to the #1 position on the distributor housing as described below?



The engine should be set on TDC (Top Dead Center) with the distributor cap removed, and there is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. (Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing)

This static timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.



If the engine is at TDC and the ignition rotor does not point to the #1 mark on the distributor housing, then loosen the hold down bolt to the distributor and turn the distributor until the rotor is pointing to the #1 mark on the distributor and then tighten the distributor hold down bolt.

Cylinder 1 is not firing


Instructions1 Use a wiring diagram for the year model of your vehicle. Locate the terminals running into and out of the ignition module. Placement of the module varies from model to model so check the appropiate service manual of your vehicle for the exact location.
2 Turn the ignition on and use your DVOM to check for voltage to the ignition module and the positive terminal of the ignition coil. Place the negative lead of your DVOM to a solid ground and use the positive lead to probe the wires running to the ignition module and to the ignition coil.
3 If your DVOM shows that voltage is present at both locations, remove the DVOM leads and set the meter aside. Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.
4 If your test light does not flicker on and off, visually inspect the wires running into and out of the ignition module. Look for burn marks, melted wire insulation and breaks in the wires. Use your wire splicing tool to remove the bad area in the wire and use your wire connectors and splicing tool to repair the faulty wires.
5 Use your DVOM to check for an open circuit condition in the primary coil winding. Touch the negative probe to the negative terminal on the ignition coil, touch the positive lead to the positive terminal. Set the meter to read ohms. If the reading shows infinite ohms, your ignition module is faulty and should be replaced. Follow the service manual instructions for replacing your ignition coil.
6 Look to see if the DVOM test shows low to no ohms; if so, then you have a faulty ignition module that will have to be replaced. Follow the service manual instructions for your vehicle to replace the module.

How to replace ignition coil


there are 2 types of ignition coil: in the 1st picture (the red one), you just need to remove the screws attached to the vehicle, remove the 2 smaller wires, then remove the high tension wire. REMEMBER to mark the wire for the positive(+) terminal of the ignition coil. for the 1nd picture, this requires some skill. this type of ignition coil is placed directly under your distributor. so if you are not familiar with ignition timing (timings dictated by the angle of your distributor), do not replace the ignition coil by yourself

There is a misfire in my engine, changed plugs & wires. now it reads that the fuel leveling sensor is bad, will this help?


If there is a misfire, the cylinder that it is misfiring in will be recorded as a code in the computer.

Have the car scanned to determine which cylinder is bad. Then, replace the coil pack going to that cylinder.

1999 silverado 4.3 cranks but no start can hear fuel pump, swaped out coil and crank sensor w/ known good parts no change, engine did start once after coil was changed ran rough and stalled and wont...


First check to see if full battery voltage is even getting to the "Pos" (+) positive side of the ignition coil when the key is in the "Run" position, and also that full battery voltage is getting through the "Pos" (+) or positive side of the ignition coil and over to the distributor ignition module

The ignition module and the pick-up coil/stator located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil, and a faulty ignition module can cause any one of these systems to malfunction.

That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores. If the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show an open loop or an infinite reading between each wire and ground) and if the pick-up coil/stator is found to be faulty then replace the entire distributor, or the distributor will have to be dis-assembled to install a new pick-up coil/stator.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

To replace the distributor follow this procedure;

The ignition timing is not adjusted with a timing light or with the engine running, and to set the ignition timing follow these procedures.

There is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. This "static" timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.

Removal;

1. With the engine at top dead center.

2. Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing indicating the number one position.

3. With the engine on top dead center the ignition rotor should be pointing to the number one mark or notch that is on the distributor housing, Then make a reference mark of the position that the ignition rotor is pointing to (out on the engine or firewall) and the more precise you mark the position, the easier the installation of the new distributor will be. This will be reference mark #1.

4. Remove the distributor lock down bolt, (the lock down clamp will most likely be attached to the distributor and if so it should not be removed from the distributor) then slowly lift up on the distributor about three inches and note the direction that the ignition rotor turns, and when the ignition rotor stops turning then mark the position that the ignition rotor is pointing to (out on the engine or firewall) and then lift the distributor striaght up and out, and remove the gasket or any left over gasket material from the intake manifold. The more precise you mark the position the easier it will be to install the new distributor and an assistant might be helpful. This will be reference mark #2

Once the distributor has been removed it is important that the engine does not get cranked over by the starter or the crankshaft turned at all, or the reference marks will become useless.

Installation;

Be sure that the new distributor is complete with a new module and that there is a new gasket in place on the distributor.

1. Lower the distributor with gasket down into the distrbutor well and align the ignition rotor with the #2 reference mark and when the distributor gear engages the drive gear on the camshaft then the ignition rotor should turn to the #1 reference mark as the distributor sets all the way back down flush on the intake manifold.

2. Install and tighten the lock down bolt, and If the distributor is properly installed then the ignition rotor should be pointing to the #1 reference mark and the #1 position on the distributor housing with the engine on top dead center.

Replace the distributor cap and connect the spark plug wires, and see if the engine will start, if the engine does start and the check engine light does not come on (assuming that it was not on before) then the distributor is properly installed and there is no further timing requirements.

Let me know if you require any further assistance.

Will randomly not start. no spark to plugs. cranks fine.


This is probably a coil pack problem or the connections for the coil packs are corroded. Mark all the spark plug wires and where they go on the coils, remove the coils from the plate they are mounted on and clean the traces with a pencil eraser, and wipe clean with rubbing alcohol on a clean cloth. Do the same on the coil packs. Replace them, then reconnect the wires and check.
