Question about 1991 Mitsubishi Eclipse

2 Answers

Car will not start

The Car Model: actually 1994 Mitsubishi Eclipse FWD 1.8L

I've noticed you expertise and want to know if you can help me.

OK, first off the car will not start, there's fuel reaching the fuel rail. I got spark, checked the spark wire, distributor, timing etc. Nothing appears to be wrong with the ignition system.

However, a couple of things have occur in the past month or so, Fuel delivery was a problem so I replaced the fuel filter and it ran fine for a while. More recent the same problem occur when the car would drive for while then die and start back up again. After I got it home I checked the fuel pump (working). After that, for a good 3 weeks it ran fine. And today it seems like I have pressure up to the fuel rail, additionally if fuel delivery was a problem, I sprayed starting fluid into the throttle body to see if the car would even start, which of course it didn't.

Which brings my problem back to Ignition. Or something I'm missing completely. Just point me in a direction and I'll check it out.

Hes right in the fact that it is most likely the "brain" or the ecu as a tech would know it when dsm ecu's are exposed to high heat or very cold temeratures it is common for them to go out primarily on the injector circuit my sugsetion ist un bolt the fuel rail and point the injector away from you (preferable into a drip pan) and try to turn it voer that will tell you if they are working and just to check how did you determine that you have fuel pressure up to the rail because the only way th really tell is to remove the rail or install a gauge at the rail also fuel pressue regulator could be jammed and letting the fuel just run right back to the gas tank probably is the ecu though

Seems you have done everything right. Not an expert but maybe have the brain checked out..does sound like it is an ignition problem. The only thing I could maybe think of is that the fuel pump is not working correctly..not enough presure.Myself, I would have the brain checked then if you are getting good spark on the number one cylinder I would re-think the fuel pump. Good luck..hope to hear back on what you found.

1999 Mitsubishi Eclipse whining noise from the rear when accelerating


A whining noise during acceleration usually, is from the gear set, indicating the pinion is too close to the ring gear.
I believe the eclipse is a FWD car though. Could it be the transmission you are hearing?

How do you repair spun bearings on a 1994 Mitsubishi eclipse Gst ?


if the bearings or even one bearing has spun, the lower end of the motor needs new bearings and the crankshaft must be "turned" or resurfaced.. this requires pulling the engine... if you drive this vehicle in this condition, you will have catastropihic engine failure which would totally destroy the motor probably.. If you or someone has the expertise to remove the motor, putting in a "crank kit" is not difficult for anyone with a little mechanic experience.. but, basically, this is time to rebuild the motor whether you just do the crank kit or go ahead and go all the way with it since you already have it out and opened up...

Turn your steering column while turning on the car this should help. I had a problem with mine once and it did this (wouldn't start) but once the battery was replaced problem went away. You could also have a defected battery which also happened to my 2001 Eclipse RS last year.

a blown head gasket doesn't always leak into the oil, it could be going out the exhaust. Do you get white smoke out the tailpipe? Also check passenger side floorboard and see if it is wet, if it is it could be the heater core. I have to assume you don't notice water under the vehicle when you park it?

I have a 2003 mitsubishi eclipse spider, how to change the spart plugs


i'm guessing you're asking because it's a v6 FWD and you don't know how to get to the spark plugs along the firewall. you will need to find the front motor mounts or the anti torque bolts whatever you wanna call it and make your motor swing. you can do that by locating your front motor mounts or side or even rear. i'm not sure with a eclipse but once you've found the anti torque bolts attached to it and removed them you can roll the car forward and it should leave about 6 inches of space behind the engine to get the those spark plugs. front should be easy
