1999 Mitsubishi Eclipse - Answered Questions & Fixed issues

HI. The fuel filter is located in the engine compartment, mounted to the firewall. Extraction will be easier if the air inlet hose and upper air cleaner housing is removed from the vehicle. This will expose the filter and allow for a better extracting experience.

Check you idle air bypass valve. Remove it and clean the inside port and surface on the plunger.

You may have jumped the timing on your car. If you are flooding out two of the cylenders this tells me that you have done so. Take it to a professional and have them look at it, unless you are comfotable with replacing and retiming your belt.

get the workshop repair and service manual and fix the problem just go to the given link once you will say thanks to me i am sure http://toolsnyou.com/

You have an electrical short issue. Check all your earthing connections to the vehicles body. Check the earthing to the engine and check for any damaged wiring causing to earth on the body. Check your sensors etc. Good luck!!

idling is the the idler valve on the intake usually just needs a clean. as for no power this can be the throttle sensor, if the throttle has blank spots it would cause this problem. if the fuel filter has not been changed in a long time it could need changing, especially if not in the last 5 years., air filter could also need changing if this has not been done for a long time. remove the air filter and check its color if its completely black change it, this can also contaminate the maf sensor, this you can clean with MAF sensor cleaner its best to clean this as it will cause engine problems such as you have. so as to conform do these first. 1. check air filter. 2. clean the idle valve. 3. clean the MAF sensor. do these 3 first before anything ells.

run the fault codes first as that always saves money backfiring is ignition timing or valve timing poor performance could be problem crank position sensor or camshaft position sensor or problem ignition control module but the codes will show the problem area

Advise Stop Driving Untill is Fixed. There may be a few things you can do, to fix the knock before it gets worse. The worst case is If the knock is a deep sound and is loud, that indicates the rod bearings are worn out, and pretty soon the bearings will fail, and most likely the car will leave you stranded. What Does It Mean When an Engine Knocks YourMechanic Advice

time to have the battery , alternator tested by an accredited auto electrical shop batteries test good but fail if a load tester is used and having to jump start it indicates that the battery is not good If there is not enough power available to run the ECM then it will die when the battery voltage drops below required voltage the fact that ir runs for a while and dies indicates that the alternator is not producing sufficient power to run the battery and the ECM again indicating a bad battery

Sounds like a vacuum leak.. or you have a sensor out.. like your IAC-Idle Air Control

Tighten the cylinder head bolts in the sequence shown in figure. Using the 4 step torque turn method, tighten according to the following values.

1. Tighten center fasteners 1 thru 6 to 33 Nm (25 ft. lbs.) . Then outer fasteners 7 thru 10 to 27 Nm (20 ft. lbs.) .
2. Tighten center fasteners 1 thru 6 to 67 Nm (50 ft. lbs.) . Then outer fasteners 7 thru 10 to 27 Nm (20 ft. lbs.) .
3. Tighten center fasteners 1 thru 6 to 67 Nm (50 ft. lbs.) . Then outer fasteners 7 thru 10 to 27 Nm (20 ft. lbs. ).

Then tighten all fasteners 1 thru 10 90°turn . Do not use a torque wrench for this step.

Well, it sounds like it is a problem in the fuel pump circuit. A lot of problems don't set a code, but if you know someone with a code reader or scanner, or if you get it running to drive it to Autozone or O'Reillys, Pep Boys, or most auto parts stores , you can get a free code scan service. Only takes a few seconds, good to know if your engine computer has detected anything. So you put a new pump in. If it turns on, it should put enough fuel pressure up to the engine. Here's how to check if the pump is turning on as it should to start the car: turn the ignition key to on, not start, and listen for the fuel pump to turn on for 2 seconds. You should hear a hum or buzz from the tank for about 2 seconds. If you do hear it, and the fuel filter is not plugged up, the engine should have enough gas to start. If the filter is not plugged up, and the only way to start the engine is with starting fluid, then the problem may be in the fuel injector circuit. Now if you do not hear the fuel pump turn on (2 seconds) with key in on, then the problem is in the fuel pump circuit. This can be difficult to diagnose, not feasible without a voltmeter and a wiring diagram of the car, so you would probably need experienced help. If you put the pump in yourself, you are a good gear head. buy a digital voltmeter and a repair manual and go to learning while you fix it your self.

You can't rule that out, a computer failure, but some testing would have to be done to truly determine the cause. The computer should send a signal to the fuel pump relay to turn the fuel pump on, both at key turned to on, and when key is in start-cranking the engine over. If you have to use starting fluid for hot restarts as you described (will it stay running then after starting it with the fluid?)...then it seems to be a fueling problem. I would say check fuel pressure, auto parts stores rent or loan them. It may be, for whatever reason, the pump is not being turned on through the fuel pump relay when it won't start without starting fluid.

run the fault codes look for problem with injectors and wiring and low fuel pressures.

your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your buick dealer to get a new one,they are programmed for each car only,you cannot bypass it.

call your dealer only

Measure or have a reliable mechanic measure fuel rail pressure. I still say the problem is in the fuel delivery system.

The sensor to the oil pressure gauge is the large dome shaped sensor adjacent to the oil filter. The sensor to the oil light is in front of the dome shaped one both have one wire coming from them

You need to purchase a new door handle the lock cylinder is connected to the assembly. Take the handle off and see if you can work around replacing the entire thing other wise let me know if you need a replacement I have access to a few.
