The best way to check for spark is to remove a sparkplug wire from one of the sparkplugs on you engine and then take one of the spark plugs that you replaced and connect it to that plug wire. Make sure the plug is touching bare metal and have someone crank your engine. You should see a spark at the end of the plug. As far as a stuck injector you need to see if your getting spark first. Let me know what you find.

1986 Subaru GL 4 Door Sedan problem: Shuts down after fifteen minutes of driving. Let sit for 1hr restarts normal for another 15 min.Temp. Normal gas meter always at more thn half Opinions heard Fuel...


Fuel pump heats up and malfunctions??? HaHa that's a good one. Tell the dope that told you that, I said the fuel pump is only going to get as hot as the fuel it is sitting in....or at least, lets hope so, unless you like to see bombs go off!

The best advice I can give you is this:
1. Check to see if there are any fault codes in your computer. (On an '86 Subaru, the computer might not be very smart, but check it anyway.)

2. If there are no codes, run the engine untill it stalls, then pull one of the spark plugs and see if there is any spark when you try to start it.

3. If it has spark, then you should check to see if it is getting fuel.

You have to find out which system is failing (Spark or Fuel) before you can even guess what is causing the problem.

Put new fuel pump and fuel regulator now floods out car, 1992 subaru legacy.


what you need to do is test the injectors, they can occasionally get stuck open. The easiest way to test them is with a mechanics stethascope, or a long screwdriver if you have good hearing, you just listen to the one by one while the motor is running, and pay attention the the series of clicks within. after hearing a couple good ones you will get a feel for what they are supposed to sound like, any injector that does not sound like the others is not operating as it should and should be replaced. A feul injector that is stuck open will make no sound at all. It would be very odd for more than one to be stuck open so if you are not hearing clicks on multiple ones, it is likely either a problem with the power going in, or you are not listening hard enough.

1992 SUBARU LEGACY WILL NOT START


Check to see if you have fuel at the fuel rail, if you do, check the injectors to see if they are working. You can use a noid light to see if they have any pulse.

The fuel injectors


the first thing you should check if your car doesnt start is compression, then ignition, then fuel, in that order, even if you got spark and fuel without compression your going no where

If you don't have a distributor for the ignition then the ECM, computer, controls the timing. To adjust the timing you have to have an OBD tool to plug into the cars diagnostic plug to m ake adjustments. If it's running a little rough go ahead and run a couple of tanks of gas through you car before worrying about the timing. Use a fuel injector cleaner in your gas tank like Lucas brand. Some Autozones will plug their units in and read codes for you if your concered about other problems. Good luck.
