fuel filter or a fuel pump could also be plugs, wires, cap and rotor I would try fuel filter first then take a plug off a cylinder and hold it close to screw driver or something(dont hold unless have rubber to grip to please dont get shocked) if it doesnt spark your not getting spark and try plugs wires cap and rotor if it does spark then open gas lid have someone turn ignition switch on and listen if you here the fuel pump is still good if not replace it. It does sound like a fuel pump

Toyota 4runner sr5 won't start its getting gas and spark.


Sounds like the problem is beyond your ability to diagnose

Too much fuel could be a leaking fuel injector or fuel pressure
regulator.

Too much gas & a no start isn't really the issue

Did it start & run before you did the wires,I would check your work
& mark the wires with a pen & also have diagram on paper before
you start a job like that. Especially when if you have no reference
material.

You put a mechanical fuel pressure gauge on a running engine
& the apply vacuum with a hand pump to regulator to watch for
pressure change,eg: pump pressure vs: regulator press

1995 ford contour cranks but won't start, change fuel filter, fuel pump, and spark plugs. Not getting any spark.


Have you ever heard of testing before replacing parts ? Fuel pressure an flow tesing , testing the electrical circuit for the fuel pump , amp draw testing , voltage drop testing etc... Thier are no magical fixes in auto repair . No spark ! check B+ voltage an ground circuits for the ignition system , Ignition System Designs Operation and Testing an SD Premium video

Why does my 1995 mazda protege sputter and die when i accellerate


An engine needs three things to function correctly: (1) the right amount of fuel; (2) the right amount of air; and (3) an appropriate spark. I would also add a fourth point for a gasoline engine: appropriate compression in the engine. A worn-out engine won't perform well, even if items 1-3 look good.

Poor fuel flow is one possible cause of poor performance. A clogged fuel filter is only one possible cause of that. You might have a weak fuel pump, although with the electric fuel pump on this car, that would either have the car running or not running at all, not running poorly. You might very well have a clogged fuel injector--gas is getting there, but an inappropriate amount is getting sprayed into the combustion chambers. You might also have a clogged fuel intake screen inside the gas tank--the fuel pump might not be able to **** up enough fuel.

Air is another possibility. Check your air filter. Is it clean? A clogged air filter will cause incomplete combustion when you step on the gas because not enough air is getting in to create a proper air/fuel mixture. A simple test for this is to try running the car--VERY BRIEFLY--without the air filter. Does it run better? You should not run your car without an air filter for any longer than diagnostic reasons--sucking dust and dirt into your engine is a fast way to ruin it--but it's an easy and essentially free test you can perform. Or you can just replace the air filter if the one you pull out looks nasty.

A final consideration is spark. If you have a weak spark, you won't get as strong an explosion in your cylinders, yielding less power and stumbling. Or, if the spark comes at the wrong time, you'll have the same problem. You can check for a strong spark by taking a spark plug--an old one, a new one, one that doesn't even match your car, and using it to test the spark coming off each of your spark plug wires. Attach the plug to a wire you disconnect, ground the tip of the wire against exposed metal on your engine, and look for a nice healthy blue-white spark. If you see a yellow or orange spark, that's not so good. That could indicate a weak ignition coil--or also old spark plug wires that are leaking voltage. Spark plug wires should probably be changed every 5-6 years; they're not a lifetime part of your car.

A final consideration I didn't list previously is that you may have a bad O2 or other sensor that measures and adjusts the air / fuel mixture. A bad sensor will force your car's computer to operate on a default profile designed to let you limp home. However, it won't perform particularly well.

Good luck; I hope this gets you pointed in the right direction.

I have a 1990 mitsubishi might max it wont run smooth unless you keep your foot on the gas and keep the rpms up a little bit and it wont drive cause it stalls everytime you try to move it. ive replaced the...


You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Troubleshooting the no-start condition - from the 1990 Mitsu Mighty Max Repair Manual:

Priority Action Part Type -- Cause
1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Distributor Cap -- Distributor Cap Cracked or Burned.
3 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injector -- Dirty or Worn Fuel Injectors.
16 Inspect Fuel Pump Strainer -- Clogged or Dirty Fuel Pump Strainerat.
17 Inspect Engine Control Computer -- Incorrect Operating Information Being Delivered and Sent From The EEC.
18 Inspect Fuel Tank -- Fuel Tank Empty.
19 Inspect Carburetor -- Carburetor Flooded or Faulty Choke.
20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

Will not Start but turns over not getting gas replaced spark plugs and wires Injectors but still does not start. Put gas in by pouring it in starts but not run.


Have you checked the fuel pump and fuel filter? The filter might clogged not allowing gas into the engine. The pump might be bad so you're engine won't be getting any gas there either. Both of those are cheap and easy home fixes as well.

I HAVE A 2003 KIA SORENTO LX & IT IS USING TO MUCH GAS LATELY>>>HOW WILL I KNOW IF I NEED MY FUEL PUMP REPLACED? WHERE IS THE PCV VALVE LOCATED?


the fuel pump will not cause bad gas mileage.the spark plugs may need changing,fuel filter,air filter,plug wires(basically a tune-up),or the thermostat probably needs changing as this can cause poor gas mileage as it won`t allow the motor to get to proper operating temperature(computer monitors temp)and commands fuel injectors on longer(spray more fuel).driving habits change over time look at this also.cold whether driving also will use more fuel.pcv valve i can`t help you,maybe a parts store will show were it is if it has one.the only time you change the fuel pump is when it gets noisy or it quits altogether,or the pressure is good but the fuel volume is not to specs.

92 C1500 Chevy wont start. Changed plugs, wires, distributor, rotor and fule filter. Pump runs when key is turned on. Poured gas to the distributor and starts up and runs fine. but jerks ar high rpms...


So you threw parts at it. No harm intended. Should have started with the adding gas part first. You know the filter is new and it does run! Are the fuel pump amps correct,pump mech bound,no fuel volume, pressure regulator work correctly? Does the pump run in start mode or time out? Now the harder stuff. What does the spark and timing look like,What is the computer seeing and then what command is it sending?
