Where the injector's mount to the fuel rail and into the eng. there are o-ring's.Check the o-ring's for damage.If the o-ring that seal's the inj. to the fuel rail is damaged it will leak alot from the pressure of the pump and make the car act like it's running on 3 cylinders because there is no fuel going to the cylinder to ignite.If there is a bad seal in the area where the inj. goes into the cyl.head it will leak a little and should be fixed as well.When installing new o-ring's lube them up litely for a easier install.Be sure to clean the gas up so you dont ignite any spilled gas.Hope this help's.

I have a 95 Nissan maxima and smoke and gas coming out my tail pipe I was told that it was my was fuel regulator all I smell is gas when i my start car can some body plz help me find the problem plz


It would be unlikely gas is coming out of the tailpipe. The fuel regulator can leak internally and externally. If there is an internal leak with the regulator, the vehicle will be overfueled and will run poorly if at all with black smoke out the tailpipe and most likely the check engine light on/flashing. You may experience a fuel smell. If the regulator is leaking external, there will be a definate fuel smell. You may also have an injector or injector seal leaking as well. Depending on the engine size 4 or 6 cyl, it can be hard to spot an injector leak. However, a fuel p;ressure regulator can easily be located and checked for a fuel leak.

Fuel in filter and start pouring gas in carb, but won't stay running


Make and Model, year of vehicle?
I'm assuming the vehicle won't run unless you pour gas into the intake. If the vehicle will start and run while manually feeding gas to the engine, you can rule out spark and timing issues. Usual suspects in fuel system are dead fuel pump (electrical or mechanical?) clogged delivery system ( fuel line, filter, injector or jet) or intake leak (bad gasket or seal, vacuum leak, stuck valve). 25310438-za4bqvjhdrn3arnyccyp5xaz-5-0.jpg

White smoke coming out of tail pipe and it smells like gas when warming up.


White smoke usually means that you have a blown head gasket,need to have it check out asap,could damage motor worse and cost more.How is your antifreeze in your over flow container,Is it low,check your oil and see what it looks like,might be milky.

#3 CYLINDER IS FULL OF FEUL AND TRUCK WILL NOT START.REMOVED SPARK PLUGS AND GAS POURS ON GROUND WHEN KEY IS TURNED ON FROM #3 CYLINDER PLUG HOLE.


The Vortec engines were notorious for those kind of problems. The problem will be under the upper-intake manifold, and the fuel injector assembly will either have a cracked plastic fuel line running out to one or more of the fuel injectors, or the fuel pressure regulator that is located on the end of the fuel injector assembly is faulty or it has detached from the fuel injector assembly. Either way the lower intake manifold will be flooded with fuel anytime that the fuel pump runs.

There were two types made, the first type had fuel lines that connected to the lower intake manifold, and then from the metal fittings the fuel line turns into plastic and runs inside the lower intake manifold and under the upper-intake manifold where it runs over to the fuel injector assembly, and this type can really flood out an engine when it becomes faulty.

The second type had metal fuel lines running over the upper intake manifold and they connected to the top of the fuel injector assembly, however, under the upper-intake manifold there are still plastic lines to the fuel injectors and also the fuel pressure regulator that could be faulty and cause the engine to severely flood.

The upper-intake manifold is not that difficult to remove, and after you remove the upper-intake manifold then (replace the fuel lines to the fuel injector assembly if it is the second type) turn the ignition to the "Run" position and when the fuel pump runs you should see where the fuel is leaking/spraying from, and it will most likely be a large high pressure leak from a ruptured plastic fuel line.

Let me know if you require any further assistance.

I have spent about 900 dollars replacing sensors and electronic parts on 93 sc 300 and it is still skipping from flooding


I don't know what you have replaced, but here is a couple of things you can do, if you haven't already done so.
If the skipping is coming from one cylinder, change that fuel injector, the gas could be leaking from around the seals.
If the flooding is in more than one cylinder, have a fuel pressure test done on it. If the pressure is higher than it should be, change the fuel pressure regulator, it's round in shape and mounted on the end of the fuel rail with a small vacuum line attached to it.
I had one that the pressure was high and pushing gas past the seals in the injectors. Hope this helps, but only if you haven't already done these.

Trouble shooting


sound like flooding caused by dirty clogged fuel injectors.the injectors by being clogged and dirty.when you turn off car the injectors will leak causing plugs to foul out. go buy a bottle of fuel injector cleaner.go to gas station fill up gas tank.then pour a bottle of injector cleaner in gas tank.drive car around to allow injector cleaner clean out fuel injectors.
