Why is it that when starting the engine there is no diesel coming out in the nozle tip but why when I put a little amount of gasoline in the intake manifold the engine starts quickly?

Please be more specific here ,if you your putting fuel in manifold of course it will start ,its a compression ignition engine,if no fuel from injectors then could be any one of a number of problems so may i respectfully suggest you ask a local mechanic to investigate for you .

Where is the 2.5 d4d erg valve mounted on the engine


In internal combustion engines,exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines.EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. Thers a hose going down the rear of the engine to the exhaust pipe. It recirculates the portion of the gasses coming out of the engine by putting in back into the intake manifold, where the engine can burn it again, thereby reducing the emissions. The EGR valve is located in the engine compartment (underneath the hood). Usually on the side with the air intake manifold attatched to the side frame rail

My 2011 jeep Cherokee had a quarter of diesel in, I accidentally put in 1.5l then refilled with diesel of 12litres, it started fine and drove me home fine, Is this going to be a problem??


It is not good to have any gasoline in the fuel tank with a diesel engine. It will cause some wear to components. It would have been better to have drained the tank.
That said, back in the day some over the road truck drivers put a little gasoline in diesel fuel to stop it from waxing during very cold weather.
Your vehicle will likely keep running, I would keep topping it off with diesel fuel. Diesel fuel is lubricating while gasoline is not.

I put diesel in my F-150 unleaded gas tank and now it won't start.what do I do


I hope you've flushed the fuel tank after the mistake. There could still be diesel in the system, and diesel does not evaporate like gasoline. Diesel will, however, burn off if the engine is hot enough, so you need to get your engine started.
1 Fill your tank with the proper grade gasoline.
2 Try to get the gasoline through the system as far as possible - loosen the feed pipe as close to the carburettor or injector system as possible, switch on the ignition to get the fuel pump to displace any diesel in the pipe (remember to place the end of the pipe into a container so you don't spill the stuff on the floor). Otherwise just suck at the end of the pipe (not recommended) until the gas comes through.
3 Reattach the fuel pipe, then prime the engine with ethanol - also called Quick Start or similar.
Spray the Quick Start into the air intake while cranking the engine. It should start, even for just a few seconds. Repeat this a few times until the engine starts then let it run until the smoke from the exhaust stops. It is not the end of the world to have diesel in a gas tank, much, much worse is getting gasoline in a diesel tank!
This is a first aid remedy, hope it helps.

7.3 diesel cranking over more than my v-10 is that normal


Yes, it IS normal for a powerstroke diesel to require more revolutions of the motor to fire than for any gasoline engine. Combustion in gasoline engines is stimulated by spark plugs and many gasoline engines will start with little turning of the motor past the position where the ignition timing creates the spark and combustion occurs. Combustion forces the engine to continue rotating and combustion in that and other cylinders becomes a perpetual event. A Powerstroke Diesel engine requires more revolutions and speed of revolutions to create the heat necessary to cause the diesel/air mixture to combust. ALSO, the diesel is injected into the combustion chamber, at high pressure, by the injectors. The injectors are electronically controlled and the Fuel Control Module (computer) (also known as the Injector Control Module or ICM) tells each injector exactly when to open and inject diesel into the combustion chamber, as well as for how many milliseconds it stays open (how much fuel will be delivered). Summary, a powerstroke diesel will only begin the perpetual combustion process when the motor is turning fast enough and the pistons are compressing the volume of the cylinder into the tight space of the combustion chamber rapidly enough to create enough heat for the fuel to ignite and begin creating power to turn the motor without the aid of the starter. IN ADDITION, a Powerstroke will NOT start at all with weak batteries. Not only does the motor need to revolve rapidly in order to start, the injectors require a MINIMUM voltage of MORE THAN 12 volts in order to activate (open). The exact amount of voltage required can be different, depending on the Fuel Control Module (FCM) or "Injector Control Module" (ICM) type that is installed. (Note; terminology for the FCM / ICM tend to depend on who you are talking to, what resource you are reading, etc. They are the same thing.) If batteries are weak, the starter uses enough amps to drag the voltage down and, even though the starter turns the motor fast enough that any gasoline motor would fire right up, the ICM will never send the signal to the injectors for them to activate so, the cylinders never get any fuel and the motor never fires. I hope that helps. Yes, a 7.3L diesel will normally need to turn with the starter for longer than your gasoline fueled V10.

96 chevy suburban wont start


If you dont have scanner. You need to check battery voltage, not less than 11v but morethan 12v...then check for starter clicking and engine is carnking then u proceed to check for sparkplug have a current or none. ..if ok then check for fuel pressure..try to on the ignition switch and u can hear a sounds from a fuel pump if no sounds check the fuel pump relay and each electrical. .if it is ok and still not start remove the intake duct and put a little amount of gasoline to the throttle body and this time ur engine will be start smoothly..

Gasoline in a diesel tank


Hi,Did you start the vehicle after you put the gas in the tank? A drain plug is fitted underneath the tank,drain the tank of gas then fill it half way or more it may run a little sluggish at firs but the amount of diesel to gas ratio will mean it will do no harm.Hope this helps.

Had about 4 gal of diesel in tank and someone put 5 galons of gas in tank. Drove a mile and stopped for not sure how long. Went back out to start and would not start.


it all depends on how much diesel remained in the tank before the gasoline was added, and how new and sophisticated the diesel engine is. In a 2007 or newer clean diesel engine, any amount of gasoline will probably damage the sensitive emissions control components (DPF, OxyCat and SCR) and system. In older engines with much less sophisticated and "touchy" emissions systems, a lightly diluted (say 90 percent diesel/10 percent gasoline) mix would probably pass through with little or no detriment. It might simply cause reduced engine power, perhaps a bit more noise, and possibly a sharp warning from the emissions sensors that detect something other than pure diesel exhaust. It's high concentrations of gasoline that spell real trouble. Whether a modern clean CRD diesel or an old indirect injection unit, burning straight gasoline or highly diluted diesel fuel will almost certainly result in catastrophic damage to the mighty diesel engine.

I recently put in 1 gallon of diesel fuel in my car when it was almost empty and then later had an accident and car . slid in ditch but no impact. Yesterday it started after putting alittle gas in but...


Let me understand; put diesel fuel in a car designed for gasoline? If so your looking at a whirl of other issues. Diesel fuel is not as combustable as gasoline and requires much more compression (almost double) then a gasoline vehicle, also diesel fuel is more oily and will gel up in cold temps which is why there is a heater on the motor to warm the fuel before entering the combustion chamber and third the engine needs to be pre warmed (glow plugs) to help ignite the diesel fuel. I would start by flushing the engines fuel system/tank and hopefully the injectors/fuel pump werent damaged/clogged. Its prob smoking because the fuel isnt igniting 100% and its like burning oil, it doesn't combust/explode like gasoline it just burns black due to incomplete combustion.

Can I use desil oil 15/40 for toyota 4runner v6 gas 1996


do not put that oil in your gasoline engine. diesel and gasoline motors are completly diferent as are the fluids you put in them. you MUST use car motor oil and not diesel oil or you're motor will need a full rebuild after 100mi or so.

Mistakinly put 50 litres diesel in my almost empty petrol tank


The first thing i'd tell you is to not run the engine at all before fixing this if possible. Diesel fuel doesn't burn very good in a gasoline engine, if at all... There is not enough compression in a gas engine to get the diesel hot enough to burn, even with a spark plug.

There is a few ways to go about this but the easiest one is to find and disconnect the line coming from the gas tank to the engine, as close to the fuel pump as possible (preferably before the filter) and route it to an empty container, then jump 12V to the fuel pump motor terminals, or jump the fuel pump relay terminals (to get the pump running) and let it pump the diesel fuel out in the container...

As a precaution I'd change the fuel filter after this, fill the tank back up with clean gasoline, and give the car a good run... You can expect the engine to smoke and run bad for a little while, as there will still be a little diesel going through.

As for the cost to get it done, I really couldn't give you a straight answer... They could do it like I said or another way (drop the gas tank...) It's not that hard to do if you do it yourself or find someone you know who can do it or a good "backyard" mechanic, but I'm sure some of the shops out there could write up a nice repair bill for this...
