Question about 1990 Mitsubishi Eclipse

2 Answers

No fuel to cylinder

1990 Eclipse 1.8non-turbo 82,000 orginal miles
I have fuel to the rail up to the injectors. If I pull the wire lead to the injector and hit it with a test light, I get bright light on 1 side, and a dim light on the other side. I do not know if I have a pulsing light when cranking the engine as I don't have a noid light. If I open the throtel on the plentim and spray starting fluid or dump gas in, the car fires immediately. Is it the crank sensor, cam sensor, or e.c.u.? And...how do I check these parts and in what sequence? The crank and cam sensors I can't even locate.
Thank you for any help you can give me in a solution!

Cam and crank sensors could possibly make them fire wrong but not stop them from working all together its ur ecu i have had to replace at least 20 of the with the exact same issue as long as you have good pressure to the injectors and everything is hooked up properly your gonna need an ecu sorry but good news is depending on your location they are relativly cheap

The only thing I can suggest is that you try to quiz the ECU which needs specialist equipment.
Non injection of fuel can come from several causes, and without the correct equipment, it will be a game of process of elimination.
Crank sensors are the usual ones to fail if any, and usually sit on the side of the flywheel. Look for cables going down the side of the flywheel housing. Crank sensors can be tested with a diode meter and a magnet - giving a change of output when a magnet is passed close.

Check all available keys if it has an immobiliser fitted - sometimes it's a wiped chip in the key, then check sensors, and finally ECU. I've had a blown ECU when a coilpack went faulty. Changed everything - then finally ECU solved it.

1996 mitshubishi eclipse 2.0 non turbo. It runs but has no injector pulse on cylinder 3


Check for pulse about two inches back on the wires behind the plug. Wires tend to break at the plug. No pulse, you have to trace to the ECM, check there. If it is there run new wires to the injector. Not the, replace the ECM. A driver inside it has failed.

Number 5 cylinder injector fires intermietenly.i replaced injector and injector plug.


It is impossible to answer your question without knowing the YEAR, MAKE, and MODEL of your vehicle.
That being said, either the fuel injection controller has failed, or there is a problem with the wire leading to the injector, or there is an obstruction in the fuel rail preventing fuel from reaching the injector. Use an circuit tester to see if the injector is regularly receiving a pulse. If it is not, you have a wiring issue or a bad ICU. If it is getting a regular pulse, you have an obstruction in the rail (or you still have a clogged injector).

Got some bad gas, changed filter and plugs, one cylinder studders and fouls out plug. im thinking maybe clogged injector?


check you have pushed down the rubber boot that covers your plugs..to remove your injectors care needed .due to risk of fire. put cloths under your fuel rail.take off your battery lead.remove the bolts on the fuel rail.pull off the clips holding the injectors to your fuel rail. now pull up the rail.your injectors should lift off at the same time.they are being held on only by an O ring.so twist and pull them out.then fallow the procidure for cleaning them.or send away to be cleaned.

No signal to fuel pump or injecters


Pressure in the rail indicates the pump is working.
When the key is turned on, the pump will come on for about 2 seconds to pressurize the fuel system. Then pump will shut off and not come on again until the engine is cranked. When cranked or when running, the pump will be on full time. To check if the pump is getting a signal, the engine must be cranking over. Or you may pick up that 1 or 2 second signal when the key is first turned to on. Is this the way you checked for power to the pump? How much pressure are you getting at the rail? Any pressure at all means the pump put it there.
Injector circuit test: Use a testlight and ground it to the engine. Pull off an injector connector and turn key to on. Probe the two wires to the injector. One wire should have power and light the testlight. If it does, the power side to injector is good. If nothing there, the injector drive circuit is out.
If you got a steady light on one wire, then check the injector ground circuit. Move the testlight lead from ground to the positive battery post. Now probe the injector connector's wire that did not light the testlight, while someone cranks the car over. If working right, the testlight should now be blinking, meaning the computer is properly grounding the circuit for injector to pulse. If both tests pass, the injector circuit is working right.
Good luck.

How to install a fuel injector on a 2002 jeep liberty 3.7


so that mean the old one is all ready removed.?
or did you mean all steps in the fsm for INJECTOR.
the steps are the same on all EFI fuel rail injectors.
you could google that or you tube it or read the FSM.

hide call keys from step 2 on, or very bad things can happen.
(wife or kids no aware of danger)
ill just cover the (basics)
1: per FSM , depressurize the system, in can be at 60PSI
parked. so avoid fuel in eyes, or a fire. we do that first.
gain access to rail under failure. (RUF) (no barking)
2: remove injector X , wire plug. (failing)
3: then detach the injector rail clamps the both rails off as one....
injector are all now loose, to pull off.
4: add new seals to new injector, and install in reverse order.

that's it, only the gain access , varies,... mostly.

last depressure steps:
run engine,
remove fuel pump relay, engine stalls. key off, hide keys
!

next tje FSM words (just the OFF section)

  1. Remove fuel tank filler tube cap.
  2. Perform Fuel System Pressure Release Procedure.
  3. Remove negative battery cable at battery.
  4. Remove air duct at throttle body air box.
  5. Remove air box at throttle body.
  6. Disconnect fuel line latch clip and fuel line at fuel rail. A special tool will be necessary for fuel line disconnection.
  7. Remove necessary vacuum lines at throttle body.
  8. Disconnect electrical connectors at all 6 fuel injectors. Push red colored slider away from injector. While pushing slider, depress tab and remove connector from injector. The factory fuel injection wiring harness is numerically tagged (INJ 1, INJ 2, etc.) for injector position identification. If harness is not tagged, note wiring location before removal.
  9. Disconnect electrical connectors at throttle body sensors.
  10. Remove 6 ignition coils.
  11. Remove 4 fuel rail mounting bolts.
  12. Gently rock and pull left side of fuel rail until fuel injectors just start to clear machined holes in cylinder head. Gently rock and pull right side of rail until injectors just start to clear cylinder head holes. Repeat this procedure (left/right) until all injectors have cleared cylinder head holes.
  13. Remove fuel rail (with injectors attached) from engine.
end expert.

Okay first i want u all to know i have been laid off and most of these site what money dont have none because of my car. Car doesnt want to start . I have replace oxygen sensor crank sensor the camshaft...


Sounds like your fuel pressure regulator is bad off the fuel rail. Is yours Turbo? If so, Napa p# CRB219788, not turbo, CRB 219796. you may have fuel to rail, but the regulator controlls fuel to injectors

Two questions where are the fuel injectors located and how do you pull the inside front passenger door panel off after remoing all the screws? i'm trying to help a friend of my wife who has been laid off...


The door panel will likely have press in clips as well, you will need to use a srewdriver or something to pry the panel away from teh door itself. Start at the bottom and pry slowly, the clips should pull out.

You didn't mention the engine type, The 4 cylinder is TBI which means that the injectors will be in the throttle body itself, you should be able to remove the top ( air cleaner ) section and see the injectors.

If this is a 3.1 v6 the injectors are in the lower intake manifold on the runners right as mate to the head. they will have fuel rails that attach to them on the very top, and a connector with 2 wires that attaches to the side of the injector right below the fuel rail.

1990 mitsubishi eclipse wont stay running


ok heres the thing when a car sets for a long time you have to do more then just clean the tank you also need to flush and replace all fluids in it and replace the fuel filter (that one is key because it empties out the fuel lines and injectors) and also please do youself a favor and replace the timing belt i can not stress that enough every 60,000 miles or 18 months please just to be safe replace the timing belt these 6 bolt 2.0 engines are great and so easy and cheap to build but if you brealk that timing belt you will be buying a new engine but truth be told sonds like you have and intake sensor thats gone out pop ur air can off and check the mas for a wasp nest or something like that
