My Mitsubishi 4G13 SOHC engine unable to start. Found no spark at all on all 4 spark plugs. Remove and check the spark distributor unit but cannot determine which component are at fault. There is a supply voltage to the distributor unit but engine still refuse to start. Can anyone help me on this. Thank you. M.B Rejeld

I'm sorry to hear that you're having trouble with your 1989 Mitsubishi Eclipse. Here are a few things that you can check to try to get spark to the spark plugs: Check the spark plug wires: The spark plug wires can become damaged over time, which can prevent spark from reaching the spark plugs. Inspect the spark plug wires for any cracks or breaks. If you find any damage, replace the spark plug wires. Check the spark plugs: The spark plugs can also become fouled or damaged over time, which can prevent spark from reaching the spark plugs. Remove the spark plugs and inspect them for any damage. If you find any damage, replace the spark plugs. Check the ignition coil: The ignition coil is responsible for generating the spark that ignites the fuel in the engine. If the ignition coil is faulty, it can prevent spark from reaching the spark plugs. Inspect the ignition coil for any damage or signs of wear. If you find any damage, replace the ignition coil. Check the distributor cap and rotor: The distributor cap and rotor are responsible for distributing the spark from the ignition coil to the spark plugs. If the distributor cap or rotor is faulty, it can prevent spark from reaching the spark plugs. Inspect the distributor cap and rotor for any damage or signs of wear. If you find any damage, replace the distributor cap and rotor. If you have checked all of these things and you are still not getting spark to the spark plugs, it is possible that there is a problem with the engine's computer. In this case, it is best to take the vehicle to a qualified mechanic for diagnosis and repair. Here are some tips to help prevent these problems from happening in the future: Change your spark plugs and spark plug wires according to the manufacturer's recommendations. Keep your engine clean and well-maintained. Avoid running your vehicle on low fuel. If you notice any problems with your vehicle's performance, have it checked out by a qualified mechanic as soon as possible.

water in the distributor cap, ht leads , computer harness plugs, around the plugs, coils
Use WD-40 and spray liberally over all electrical components and wires.

Hi mate start at the easiest point which will be to check your EARTH to make sure everything is earthed.

According with engine sizes, check this for 2000 Mitsubishi Eclipse GT 3.0 liter SOHC V-6





or 2000 Mitsubishi Eclipse GS 2.4 liter SOHC L4



Hope helps.

I do not have a breakdown diagram for a distributor, but just the firing orders and description of ignition system for the Dodge Colt and related models (based on Chilton manuals) if that's what you're looking for: FIRING ORDERS Fig. 1: 1990 1.8L SOHC Engines Firing order: 1-3-4-2 Rotation: clockwise

Fig. 2: 1.6L DOHC Engine Firing order: 1-3-4-2 Distributorless Ignition

Fig. 3: 2.0L Engine Firing order: 1-3-4-2 Rotation: clockwise

Fig. 4: 1.5L Engine Firing order: 1-3-4-2 Rotation: counterclockwise

Fig. 5: 1993 1.8L Engine Firing order: 1-3-4-2 Rotation: counterclockwise

Fig. 6: 2.4L Engine Firing order: 1-3-4-2 Rotation: clockwise

To avoid confusion, replace spark plug wires one at a time. --- Distributor REMOVAL & INSTALLATION Although the distributor can be removed from the engine no matter which cylinder is about to fire, it is a good idea to have number one cylinder at TDC before distributor removal. 1.5L, 1.8L, 2.4L SOHC Engines

1. Disconnect the negative battery cable.
2. Disconnect and tag the spark plug wires from the distributor cap.
3. Disconnect the distributor harness connector.

4. Loosen the distributor retaining bolt and remove the distributor from the engine. To install:
   
5. Rotate the engine until No. 1 cylinder is at TDC on its compression stroke. NOTE: Be careful not to turn it to the No. 4 cylinder TDC on its compression stroke by mistake.
   
6. Align the distributor housing and gear mating marks.

7. Install the distributor into the engine, while aligning the fine cut (groove or projection) on the distributor flange with the center of the distributor mounting stud.
8. Install and tighten the distributor retaining bolt.
9. Reconnect the distributor harness connector.

11. Reconnect the negative battery cable.

Here is the firing order diagram for your vehicle, and let me know if you require any further assistance.

hi, in the american database for alldata, there is no lancer in 1990, if your engine is dohc, or sohc though, i checked 2.0 and 1.8, both are 1.0mm - 1.1mm gap. shouldn't be any problem running at these gaps, most every mitsubishi engine runs at this spark plug gap.

different things are happening here. get wheels balanced, and motor checked.

Free online repair manuals can be found at autozone.com. You just have to register and look around you will find wire diagrams in the manual.
Does the engine crank over but does not start or is it not turning over?
Are you getting any fire? You may check this by removing one spark plug and putting the plug wire on the plug. Then touch the end of the plug to ground, set it against the engine block or valve cover. Have someone turn the engine over while you watch the end of the plug to see if there is a spark. Remember do not hold the plug or wire because you will get shocked.

This sounds like the timing belt is shot. Remove the distributor cap, have your helper crank the engine. Is the rotor turning?? If not, then it is the timing belt. Some engines are rather forgiving when the belt breaks, some will get bent valves. Frankster016
