Mitsubishi Eclipse

I have 2 plastic hooks or something similar that hold the fuel rail in place and currently one of the 2 hooks broke off, would that cause my cars engine to bog down and nearly die when I’m braking and slowing down if the fuel rail moves?



No. If the fuel rail were to move enough to do something you would notice fuel spraying all over under the hood and leaking onto the ground. Not to mention the ability to smell raw gas.

Fuel Pressure Relief

Before any fuel system service can be performed, pressure in the fuel system must be released to prevent personal injury or damage to the vehicle.

Will the engine of an Mistubishi Eclipse 1996 fit in the body of a Mitsubishi eclipse 1999?



The second generation of the Mitsubishi Eclipse was produced from 1995 to 1999. So the short answer is YES. There are some variables to consider. Make sure the engine replacement engine is the same so that the electronic controls will work properly.

1995 -1996 Mitsubishi Eclipse Trim Levels

The Eclipse was available in seven trim levels: Base [Only available in 1996.5 (mid-model year)], RS (Rally Sport), GS (Grand Sport), GS Spyder, GS-T (Grand Sport Turbo), GS-T Spyder, and GSX (Grand Sport X=AWD).

  • Eclipse RS: Base model equipped with a 140 hp (104 kW) and 130 lb⋅ft (176 N⋅m) of torque 2.0 L 16-valve DOHC Chrysler 420a engine
  • Eclipse GS: Equipment upgraded model equipped with a 140 hp (104 kW) and 130 lb⋅ft (176 N⋅m) of torque 2.0 L 16-valve DOHC Chrysler 420A engine. The European variant of the GS had a naturally aspirated, DOHC 16 valve 4G63 engine producing 150 HP
  • Eclipse Spyder GS: Convertible model equipped with a 141 hp (105 kW) 2.4 L 16-valve SOHC Mitsubishi 4G64 engine
  • Eclipse GS-T: Upgraded model equipped with a 210 hp (157 kW) and 214 lb⋅ft (290 N⋅m) of torque turbocharged and intercooled 2.0 L 16-valve DOHC Mitsubishi 4G63 engine
  • Eclipse Spyder GS-T: Convertible model equipped with a 210 hp (157 kW) and 214 lb⋅ft (290 N⋅m) of torque turbocharged and intercooled 2.0 L 16-valve DOHC Mitsubishi 4G63 engine
  • Eclipse GSX: AWD model equipped with a 210 hp (157 kW) and 214 lb⋅ft (290 N⋅m) of torque turbocharged and intercooled 2.0 L 16-valve DOHC Mitsubishi 4G63 engine[15]

1995 -1996 Mitsubishi Eclipse Engines

All motors are four-cylinder gasoline engines. All have cast iron blocks with aluminum cylinder heads. The 4G63/4G64 engines retain the balance shafts for smoother operation, while the 420a does not use them. The 1995–1999 turbo engines were given an increased compression ratio of 8.5:1, up from 7.8:1, and a smaller turbo, a Garrett T25 set to 12psi in place of the previous Mitsubishi TD04-13G (automatic cars) and TD05-14B (manual cars). This was done to minimize turbo lag, which was an undesirable trait for mass-market appeal in the U.S. These changes led to increased horsepower and torque vs. the previous 1G turbos. The 2G turbo cars produced 210 hp (157 kW) at 6000 rpm (205 hp (153 kW) at 6000 rpm w/ AT) and 214 lb⋅ft (290 N⋅m) at 3000 rpm (220 lb⋅ft (298 N⋅m) at 3000 rpm w/ AT.)

The 4G63 engines found in 1990–1994 models have a 60 mm throttle body compared to the 1995–1999 MY’s 52 mm. The intake ports on the head and runners of the intake manifold are also larger on the 1G. They also have larger crankshaft bearing journals to allow better lubrication. Because they look similar, it is important to note that the 1990-1994 cylinder head is more on the side of high air volume, while the 1995-1999 cylinder head is more on the side of high air velocity.

Mitsubishi Motors quietly updated its 4G63 engine in 1998 and 1999. The crankshaft is more precisely shaved and cut compared to previous years. It is identical to that used in the Mitsubishi Lancer Evolution, which was not yet sold in North America until 2003. The thrust bearings have been revised to a “split” type to allow better lubrication and self-alignment with the crankshaft. It also had improved tuning & functionality, thanks to a new ECU, which was similar to Lancer Evolution ECUs. Although originally deactivated to protect the drivetrain, it included advanced features such as launch control, boost control, adjustable rev-limit, fuel system control and even fuel and boost map selection for certain Mitsubishi Heavy Industries turbochargers.

2008 Mitsubishi Outlander

Drove down the street stopped at stop sign. Hit gas to go and car shut off mid acceleration. No check engine light. I have replaced timing belt, water pump belt, cam shaft sensor, starter, battery. Getting spark and plenty of fuel. Car will crank but not fire. I need help. I’m afraid to buy the crank shaft sensor and that not be the issue. Any ideas?



We have developed a step by step no start diagnostic chart for just this occasion.

2016 Mitsubishi Outlander

My 2016 Mitsubishi Outlander Sport just started not starting on first try as normal. been about 4 times its been hard to start, turns over much longer before start. sounds normal as it turns over just doesn’t start right away?



For the sake of this discussion we will assume there is no check engine light on or check engine light codes present.

This is usually a sign of lack of fuel pressure. A quick test would be to cycle the ignition key several times before trying to start it. This will allow a little bit more time for the fuel pump to build required pressure. Turn the ignition key ON and hold for 3 to 10 seconds, then turn it OFF. Do this several times and then try to start the engine. If the engine fires right up like it normally did then you know the issue is fuel related.

Cranks over longer before starting because of fuel pressure

The number one reason would be fuel pump pressure loss. This can be from a failing fuel pump, failing fuel pressure regulator or clogged fuel filter.

Vacuum leak causing longer than normal crank time

There is a chance that a vacuum leak is causing an issue. Loose connections at or around the Mass Air Flow Sensor will cause a false signal to be sent to the engines computer and may make it difficult to start.

Internal Vacuum leak causing hard starting

There is a chance that the idle air control valve is sticking. When this happens the check engine light does not illuminate. A quick test would be to press down slightly on the accelerator pedal while trying to start the engine. If the engine starts easier then the next step would be to clean or replace the idle air control valve.

p0340 code. Engine runs great for 8 minutes then stalls. Will restart and run for 3 seconds then stall. Must sit for several hours–then it will start run for 8 minutes…same thing.
Runs perfect when cold. New timing tensioner, cam sensor , crank sensor, cam sens plug. all wiring checked, swapped main ECM , battery volts correct. Any ideas ?



Failing ignition components act this way. They work great cold and then break down once they start to warm up. I would look for and ignition module or coil issue.  I do not think the code p0340 is related unless the battery is weak. If the battery is 4 years old, install a new one anyway, its time.

Check connections and make certain to check the MFI Relay. That relay is part of the camshaft position sensor circuit.

2001 Mitsubishi GalantI have a clicking sound under my hood and it sounds like a sticky lifter. Is my car doomed or can I continue to drive it?


RESPONSE

Sticky Lifter

Your in luck! The car is not doomed. The engine should have the oil level checked. If the oil level is good then there is no reason not to drive it. This is assuming no warning lights are illuminated on the dash. Of course if the oil level is low, top it off before driving. If the engine does in fact have a damaged lifter you will not do further damage to it by continuing to drive it. However the ticking sound will be there until a repair is made.

You may notice a decrease in fuel mileage.

1999 Mitsubishi Triton

Car Problem

I just replaced spark plugs, leads, fuel filter, air filter, oil and filter, tappet cover gasket kit, timing kit with hydraulic tensioner , radiator , some parts at mechanics. When I drove it home it was weak on power but the mechanic said it mite need running in as the old parts were really bad. I done 24kms and used a quarter of a tank of fuel, it smelt fuely and was rough, when I went to start it the next day it would fire up it just backfires in the air box and exhaust like its misfiring, when I try to rev it, it dies like its getting no fuel or bad firing order or no air ,but the mechanic says he’s not sure to take it back and he will see if he can find whats wrong. Would u know please

Vehicle

Its a 1999 mk Mitsubishi 3.0L triton v6 manual 4×4
The fuel in old filter was black
I only done fuel filter, air n oil filters , radiator , pullys and fan belts , thermostat .
Mechanic done rest , plugs leads timing kit with hydraulic tensioner , tappet cover gasket kit
I’m getting a MAF air flow sensor tomorrow, could that be a possible problem or injectors


RESPONSE

The engines ignition timing is off. Probably one or two teeth off on the tinning. The timing belt was not double checked after installation.  A mechanic may get in a hurry and forget to rotate the engine 720 degrees and recheck the timing marks. This is a very common mistake. This should be covered under warranty by the mechanic if any was offered.
