The EFI will NOT inject if it sees no spark.!!! by DESIGN.
all EFI does that. Gasoline. engines.
so fix spark. 1st. IT'S BAD so... this works on all cars. gas.
ok, so its 95 toy corolla, no engine size stated.or country

  1. fuses good.
  2. CEL lamp glows key on, if not EFI will be dead. see #1
  3. this car has CHeck jumper "diagnostic jumper"
  4. insert the jumper ,per page on that. lost it?
  5. crank engine for 5 seconds.
  6. release key, do NOT turn off,yet.
  7. watch CEL flash out it's errors. CALLED DTC's
  8. post them. or look them up. you now know why the ECU cut injection to stop a FIRE. (flames)
  9. on new cars we use a scan tool .to do the same thing.
  10. if no errors, then the Highvoltage side is bad, COIL or the ignitor.
  11. Most PCM's can report dead ignitor.

the ignitor is driven by the PCM/ECU and monitored at all times
scan it. and win.

Still need the codes.
Injectors can go "bad" in a couple of different ways; all they are is an electromagneticaly controlled nozzle. When the ECU "fires" the injector, it pulses a ground circuit for 4-8 milliseconds, the electromagnet powers up, the valve at the bottom of the injector opens, and the fuel shoots out, under pressure. The wire can be bad/chafed/corodded/ The electromagnet may be weak. The nozzle may be stuck. Lots of things. But, to put in an injector for a number 4 cylinder misfire (p-0304 code) would be one of the last things that I would do.

SOURCE: check engine light is on the code was po300

I respectfully disagree.
A P-0300 will NOT be set in a Corolla by a dirty fuel filter.
Replacing the fuel filter could be a very costly operation, as I have observed that the fuel line threads that connect to the fuel filter easuily get damaged when removing the fuel filter.

In short, don't replace the filter until you are SURE that it is the culpit.
In this case, the fuel filter is NOT the culprit..
Save your money; and your time.
Additionally, premium fuel does not clean fuel injectors. That expense would be a waste of money. The engine will actually run WORSE on premium fuel; the engine is NOT designed to run on premium. 87 or 89 (better choice/89) is the grade to use.

If you really want to track down the P-0300 code, which is a multiple/random cylinder misfire, I would look at the quality of the fuel in the car; ie water in the gas. Second, I would remove the plugs and examine them closely. A worn center electrode will also set the P-0300 code, as will bad/weak plug wires (over 5 years old).

Please feel free to contact me back if you need further assistance. Thanks for choosing FixYa for assistance.

Most likely I a would suspect the fuel rail had moisture in it. If you checked emissions it would most likely show no HC and alot of 02 and no CO. If it does show alot of HC then I would suspect sticking valves intermittantly . The pinging really points to no fuel issue tho. If you pull the injector connector off and no change then I would remove the fuel rail and inspect. Also make sure the wires are in the correct locations. It easy to get them wrong.

2005 GRANDAM GT CRANKS BUT WONT START


Well, there are several basics your engine needs to start: Spark, fuel, compression, and correct valve timing. I am going to assume on good faith that your GT has the 3.4 liter V6. Here are a couple basics on checking fuel and spark:
GM usually puts a schraeder valve (looks like a tire air valve) on the fuel rail. This is where you connect a fuel pressure gauge to test the fuel pressure. It should be 52-59 PSI when you turn the key to run.
If your fuel pressure is good, remove a spark plug wire from one of the front 3 spark plugs. If you have a spark tester, connect it to the removed plug wire. If you don't have a spark tester, remove the spark plug. Plug the removed spark plug or tester into the plug wire. Touch the metal threads of the plug or tester to a good solid metal part of the engine using gloves or non-conducting (plastic) pliers. Have someone try to start the engine. Watch the gap at the end of the spark plug. You should see a bright blue/white spark and hear it snap every time it fires. If you don't, there may not be any spark getting to the engine. Diagnosis of the problem can be far trickier from here on out. You will need to be able to diagnose electrical problems in the fuel/ignition system to find the root cause of no fuel/no spark.

If you cannot hear the fuel pump run in the tank when you turn the key to run, try lightly rapping the bottom of the fuel tank with a hammer turned to its side (don't put a hole in your fuel tank!) while someone cranks the engine over. If the engine starts, most likely cause is a failed fuel pump. Don't expect the car to keep starting on a regular basis if it does start by hitting the tank. The fuel pump will need to be replaced.

Check ignition and gas.

Listen for the fuel pump to come on for a couple of seconds with key ON. If you hear it, pump is working, check for gas at the fuel rail on top of engine. Should have gas under pressure.
If pump doesn't come on, check the fuel pump fuse, check fuel pump relay. Last, use a test light or voltmeter and check if the fuel pump wire has power to the gas tank connector when the engine is cranked over. If power there, fuel pump will need taken out and replaced. If no power at the pump, pump circuit needs checked.

Check ignition by checking for spark at a plug wire end. Pull off plug wire from spark plug, push the boot back so metal end terminal is exposed. Hold the end terminal 1/4 inch from a grounding source like a metal bracket or bolt on engine. Have a helper crank the engine over and watch for a spark-you need to see a blue snapping spark to know the ignition is good. Maybe wear gloves or use a heavy rag holding the wire-you can get shocked if not held close to a ground. Another way is to pull off the wire from plug, remove plug from engine, then re-attach plug to plug wire, and lay the plug on top of engine where the plug threads are touching metal-now the plug is grounded. You will not have to hold the wire. Have the helper crank the engine, while you watch for spark at the spark plug end. If you have a blue snapping spark, ignition is good. It is a good idea to check for spark on more than one plug wire-maybe another coil is not firing.
If your ignition is good, and you hear the pump come on, possibly a weak pump not putting out enough pressure- then check fuel pressure with a fuel pressure gauge. Fuel injection requires high pressure, so the injectors will spray fuel out.
If still no go, scan computer for trouble codes. Check if your security or theft deterrent has immobilized the car.
Good luck.

NO SPARK WONT START


If you have no spark, try removing one of the spark plug wires from a plug, then put an old plug into the wire and ground it on the engine, then crank it over and watch the plug for spark. Still if you have no spark, you have to replace the spark plugs else you have to check the fuel pressure, or you may have a bad fuel pump.

No fuel pressure


You should check the electrical system i.e do you have spark at the spark plug ends? If no then work on this. If yes then remove the spark plugs, put half a teaspoon of fuel into each cylinder and put the plugs back. Try starting the engine. If it does then fuel isn't getting to cylinders. If it doesn't then you need a valve or complete overhaul job,

The fuel pump pressure shoud be 55-61 psi . Check for spark by removing a ignition wire at a spark plug and put a spark plug in wire and hold to engine ground and crank engine , if no spark then remove coil wire at cap and repeat.If still no spark then coil , module,,crank sensor or pickup may be the problem.
Check fuel pump pressure first and if available check for codes for possible crank sensor.

Cranks but does not fire. put gas into intake still no start.


First off check and verify you have sufficient fuel pressure with a fuel gauge if the fuel pressure is good next verify you have spark remove one of the sparkplugs and instert a spark tester into the sparkplug wire and crank the engine around and observe that there is spark, if theres spark remove all spark plugs and perform a compression test the compression should be no lower then 180 PSI for that engine, next if theres no spark unplug the 4 wire connector from the coil pack and with an ohm meter ohm across the purple and yellow wire the resistance of the crankshaft position sensor should be between 700 and 900 OHMs if its not replace the crankshaft posistion sensor its located behind the engine in back of the starter, if you dont have fuel pressure check the fuel pump relay and fuse, if they both are okay then the pump is probably bad and you will have to drop the gas tank to access the pump.

Wont start, no spark anywhere


Check the spark, remove the fuse to the fuel pump and remove one of the spark plugs. Connect the plug to its lead and position it well away from the engine against the truck frame (do not hold it) and turn the engine over, check the spark. If no spark it most probably a faulty coil. Check the impedance of the spark plug leads and replace any that are much higher than the rest. My guess is that you have spark but no fuel, What?... OK this is what I think is wrong. Your pump is fine when at position 2 on the ignition switch however when you switch to position three to fire the engine the power to the fuel pump is momentarily disconnected. A leaking fuel pressure regulator or injector would drop the pressure in the fuel line and at the same time flood the engine making it impossible to start. Once you start the engine with ether the ignition is back to position 2 and the pump can make good any loss in pressure but because the intake mix is rich this will cause the engine to run rich too. A good fuel system is capable of delivering 40 - 50PSI of fuel pressure and when switched off up to 90% of this pressure should be maintained for about 5 minutes, if it cannot check out the fuel pressure regulator and injectors. The fuel pipe should be capable of filling a pint pot in about 15 seconds, if it cannot check out the fuel filter is clogged.
Hope the above gives you some pointers

Need step by step guide on how to service a toyota yaris


Firstly look at the part numbers of the items you want to replace, oil filter, spark plugs, if you want to put new ones in, air filter and if the car has quite a high mileage, the fuel filter. The fuel filter is under the car and looks like an alumimium cylinder. If you go to a quality spares shop they can sell you reputable parts, often for a lot less than Toyota original parts. Ask them to set the gaps on the plugs and buy a gallon of the type of oil that is specified in your handbook for your type of climate. You will also need a sump plug washer.

The first thing to do would be to remove the air filter from the cleaner. This is usually held together with clips and/or screws. Clean out the inside of the housing and place the new filter in the same position as the old one. Clip and screw everything back together and that job is done.

Blow around the spark plug holes, number each spark plug lead from 1 (front of engine) to 4 (back of engine). Remove the plug leads and the unscrew the plugs. Replace with the new plugs being careful not to overtighten them and replace the plug leads onto the correct plugs.
Check your engine coolant level and top up if necessary.
Start the car and get it to normal temperature. Switch off engine. Chock the wheels, put the car in park or gear and handbrake on. Jack up the drivers side giving you enough space to slide a bucket under the engine. DO NOT GET UNDER THE CAR. Wipe around the sump plug and SLOWLY undo it. The plug is at the bottom of the sump at the lowest part of the engine. THE OIL ON THE OTHER SIDE OF THE PLUG IS HOT SO TAKE CARE. Let the oil drain. Whilst this is happening, wipe around the filter base and unscrew the filter. This will also be hot and oil will spill so make sure that the bucket can also catch the spillage. Wipe away any excess oil and make sure that the rubber seal has not been left on the engine. It is important to remove it. Place a smear of new engine oil on the new filter rubber seal and screw the filter in place. A good hand tightening is enough. By now all the oil will be out of the engine and you can replace the sump plug washer and screw the sump plug back into the sump making sure it is tight. Wipe away any loose oil. Remove the oil filler cap and pour about half the oil into the engine. let it settle for a minute and remove the dip stick, clean it off, and dip it again. You should see the oil level near the bottom of the dip stick. Add another pint and check again. Keep going until you reach the full mark. Replace the oil cap and dip stick and start the engine. Run it for a few minutes and check the filter and sump plug to make sure they are not leaking. Switch off, let the oil settle and check the level again. It will go down because the filter is now full. Top up and you are done. Look around the engine bay to make sure nothing is amiss. If the car has done about 20 000 remove the wheels and check the brakes have enough lining. Check the tyres for tread, cuts and so on. Make sure all your lights are working. Now you are pretty much good to go.

Check the backside bottom of the carb. there's a vacuum port there. Make sure it's plugged up. How's you timing? Also try rotating distributor back and forth. It may be a timing issue. Not enough or too much.
