20 Most Recent 1994 Mitsubishi Eclipse Questions & Answers

Hi Peter,

With such high revving engines (me being a Honda fanatic) you need to keep an eye on oil levels. Check the level, top up as necessary. Without the correct amount of oil in, the oil pressure cannot stimulate the switch over cam, which takes it to 8500rpm.

Also, please don't rev you car without load (ie. standing still), this causes valve lash and is detrimental to the engine. Again, please do not rev your car hard without letting the oil get up to temperature or it won't last long :)

Once you check your oil, reset the ECU by pulling the battery lead off for around 20 minutes.

Good luck and have a blast. Could you vote for me if this helps you. Thanks.

From engine first belt is alinternator/water pump belt.
Secound belt is A/C belt and tensioner.
Third belt is power steering belt to crank

problem with the manual. its missing> go to Mitsubishi, and buy one? tell them you have safety issues and get it FREE, WINK WINK????? or google all weekend... 2 choices.

Sounds kinda like a vacume leak somewhere. I would check all your vacume hoses and go from there. good luck

I doubt the problem is a fuse altho you could check them to make sure.The dash lights and tail lights are on two different circuits controlled by the headlight switch. Each circuit would need to be tested.

PCM---Powertrain Control Module (main computer)

it still should store fault codes go to a major chain autoparts store they usually test codes for free (they want to sell you the part)

Hi don, 1st id take a look at the battery termionals clean them ,then look at the cables to the starter and clean an tighten them (1 goes top the starter and 1 goes either to a ground on the frame or to a block like solenoid) after that check your fuses to starter, starter relay and main fuse or relays in the big black box under hood and also inside car as well, my guess would be bad ground wire, locked up starter, or relay. even tho you charged your battery a cell in it couldve collaped as well. Hope this helps!!

Get you a spark tester at the part store and hook it to a plug wire and see if it is getting a spark there about 8$ or you could stick a screwdriver in the plug and lay it down somewhere so it dont shock you and let someone crank it over and see if there is a spark or lol you could do like me and hold the plug wire while someone cranks it for just a sec. it will shock you though.If it is firing.if no fire could be your coil to

First thing I would do is make sure it is getting a good spark and fuel. Since you already checked compression, the only other engine mechanical problem I can think of is a wiped camlobe. After confirming spark and fuel remove the valve cover and either measure the cam lift or start it up and watch the rocker arms and make sure they are moving as much as the others. To check for spark I would make a test plug. You may also want to make a cylinder balance tester and also you may want to purchase a noid light kit to make sure the injector is getting a signal.Test PlugYou can make a test plug with a new spark plug and some wire, a mini hose clamp and an alligator clip. First open the spark plug gap to around 0.075" and strip both ends of a 16 gauge wire about 4 foot in length. Attach the mini hose clamp around the threads of the spark plug cause that is a ground and secure it with the mini hose clamp with the bare wire end in between to make a good connection. Next, take the other end of wire and secure to an alligator clip.Now, you have a test plug. Remove any spark plug boot you want and insert your test plug onto the spark plug wire end you just pulled off and ground the alligator clip. Lay the spark plug in some shade somewhere under that hood and then crank the engine and look for spark. It should crackle with sound and should be blue but red is ok, orange is a little weak. If it can jump that 0.075" gap you should have no problem igniting an engine.You can also use that to check coils on some vehicles.Cylinder Balance TestFirst of all you will need a 12-volt test light and about 8-12 inches of neoprene vacuum hose. The vacuum hose will conduct electricity cause it is carbon based, use an ohmmeter if you aren't sure and see if the vacuum hose you have will conduct.Now, cut off the same # XXXXX cylinders you have in small equal lengths of the vacuum hose. 2-3 inches will do fine. The small diameter kind like to carburetors, etc will work as long as they fit over the distributor cap tower connection.Now, mark all your spark plug wires at the cap or coil pack and remove them all. Put those short pieces of vacuum hose on the distributor cap or coil pack connections and shove the other end of the vacuum hose into the spark plug wire boot until it makes a good connection.Now connect your 12 volt test ground clip to a ground and start the vehicle. With the engine running touch the 12 volt test light to each of the vacuum hose 1 at a time and listen for the cylinder to short out and die and drop in r.p.m. They should all be about equal. If 1 or a few don't drop or do anything than you have your dead cylinder there.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

spark plug wires or dead battery

You can't trust the light sensor, so you need to get a mechanical gauge. A cheap capillary tube one is only $10.
You should also change oil.
If the engine has over 100,000 miles, you could consider 20W-50 oil.
You could also have a problem with fuel or ignition, causing oil dillution.
Does it look too thin or smell like gas?
It could also be the oil pump is bad, but that is not normally worth trying.
The number of miles on the engine would help.
But low idle oil pressure is not that important.
