Mitsubishi Repair Questions? Ask a Mechanic for Answers ASAP
Hi,Just so I am clear, the engine is not rotating at all, is that correct?
I will be leaving for the night shortly, but I will leave you with a few questions for when I return.I am assuming at this point the engine does not rotate.Do you have any noises under hood when the key is turned to the start position? (clunks, click, etc)Do you have any noises in side the dash when you turn the key to the start position? (rapid clicks, etc)Did anything notable occur just prior to this no start condition?How old is the battery (there may be a date on the label if you are unsure), and what are the conditions of the battery terminals? (looseness, corrosion, etc)Thanks
It's my daughters and I just went and looked at it. Yes it click's under the hood. Not sure where the starter is on that model but when holding he key in the "start position" I did finally see some smoke come from the front of the engine area, right behind the radiator area. I am guessing yes it is a starter problem? What is the procedure for replacing the starter? Thanks
Hi,Yes, if you are getting smoke from the radiator area, then you are probably going to be looking at a starter. The starter is located just behind the radiator, on rear edge of the engine (straight down from the oil cap).....
It is important to note that there are two probable causes for the starter to smoke, one bad, and one terrible
If the starter motor is shorted internally, holding the key in the crank condition will cause it to smoke. Repair in this situation will require a new starter.....
If there is an internal engine problem that prevents engine rotation (bearing seize, timing belt jumped), continued holding of the key in the start position will also cause it to smoke, as it will overheat trying to rotate a seized engine.
If you get a light click sound, that is a good thing. If you get a solid clunk sound, that is a bad thing, indicating the the starter is plunging correctly, but can not turn..
If there is any concern over whether or not the starter is the problem, you can try rotating the engine by hand with a 22mm socket and ratchet on the crank pulley bolt. Additionally, early models had a 1/2" square drive hole in the crank bolt so you could just put a 1/2" drive ratchet in it.
Else, you could just remove the starter and take it to parts store for testing. Replacement is pretty easy on this model and can be done in about a half hour.....
If all original, there will be a heat shield on the starter, held on with 8mm bolts, this needs to be removed.Unhook the negative battery cableUnbolts the battery cable on the starter. It will be a 12mm nut if original, 13mm if aftermarketRemove the small electrical connector.There will be two 14mm bolts holding the starter to the transmission. Remove both and the starter will slide toward the passenger side, then drop straight down out of the car.
Doug I replied with a lengthy explanation of what I have done and It still won't turn over did you recieve that?
I removed the starter and took it to auto shop is seem to work fine. I checked all he connections all the way to the battery everything looks good.
I did put the 1/2" drive on the pulley and yes I can turn it but it is pretty stiff. Kind of feels like it is going through a compression cycle. It gets easier then more difficult. Using a fairly short 1/2" ratchet and laying in front of the car I could turn it either way. which way should the motor turn normally?
I did pull the oil stick and it is at the low notch. I have the car jacked up in the front so it might affect it a little. The oil doesn't smell burnt or anything unusual.
My daughter said it was running fine she drove from Basketball practice to home only about 1 mile and parked it in the garage and this is where we are at.
What is the next step to determine if it is a motor problem? Could the time belt of gotten off when shutting it off? All seems kind of strange when you put it all togeather. Any help appreciated. Randy
I finally got time to get back to the starter issue. I did use a jumper and tried to jump the starter solenoid and see if it would pull in. It would not.
I took the starter back off and it would not work on the bench this time either. I have ordered a new starter and it will be in tomorrow.
I have a question about the signal going to the solenoid on the starter. I used my volt meter to confirm it was getting a signal to pull the gear in and engage the starter. I get a 12V signal as soon as I turn the key to the on position before I go to start? Is this correct?
Can you send me the a pdf of the electrical start circuit for this vehicle?
That's great news, sounds like the starter is kaput.
When you turn the key to the Start position, 12V is delivered to the solenoid, which acts like a relay allowing the current at the heavy cable to pass and activate the starter.
You should not have voltage at the signal wire in the run position, only in the Start position. If you are checking with the signal wire detached, double check your measurement. If you are checking with the signal wire attached, detach it and recheck; the shorted starter may be allowing voltage to pass from the cable through the solenoid.
I can supply a diagram of the circuit, I need to know if this is an Automatic or a Manual transmission though; they are different.
Yeah double check that, something seems off there.
Here is the schematic for your starting circuit:
