    Thank you. I have another question. I know all i need is to find a hot wire to the core. where can i get that from or would i have to add one myself. Do i just connect it from the switch to the core?

  • Donald Tucker Mar 14, 2011

    No. The there are two circuits in the ignition system. There is a start circuit and the regular one in use while the engine is running. There is also a voltage dropping resister to keep the points from burning up. The color codes on the wires are mostly the same but the wiring harness varies with different makes and models. You would need an older wiring diagram on a similar engine that was made before some of the electronics were installed in yours.

Car starts then dies


QUICK ANSWER

A car that starts up initially but dies immediately thereafter is experiencing a problem with either its carburetor or fuel injection system. The culprit depends on the year, make and model of the vehicle in question. Carburetors are easy to fix, while fuel injection issues cost a large sum to diagnose and repair.

FULL ANSWER

The issue with a car that starts up at first but then proceeds to stall immediately afterward is associated with the amount and quality of fuel being pumped through the engine block. The kind of car in question dictates whether a carburetor is present in the vehicle or if a fuel injection system is in charge of regulating these qualities. In instances where the automobile starts but does not continue to run, one of these two systems is present in the car and is not working properly.
These systems are susceptible to failure in cases where the wrong kind of fuel is present. This is a common occurrence in cases where a vehicle owner puts an inappropriate type of gasoline or diesel into the tank. In other instances, the trouble with the carburetor or fuel injection system is that these assets are simply worn out, broken or filled with residue.

My car started having trouble starting back up after being shut off for only a short time and now is dying while driving


the car with need to be spimmed, theres no fuel in the motor,,do you have fuel injection, if you have fuel injection you are going to find out how to get the fuel into the ejcedtor,
if you have a carburetor than just pour some gas into the carburetor and turn the key once you get the car crank over and some gas in the system the fuel will pick up and the car should run

How can i change my 87 bronco II 2.9 L from fuel injected to carbureted ?


You'll need three things to get this done: An independent distributor that doesn't require a vehicle computer, and intake manifold with a bolt pattern that'll work with a carburetor, and a carburetor. Oh, and a low-pressure fuel pump (the high-pressure one in the tank has to GO). You'll have to figure out the gauge cluster or replace all the gauges that rely on the computer.

The swap itself is shockingly easy, once you have those three parts. It's all bolt-together, and suddenly your vehicle just got a LOT simpler and more intuitive to work on. The intake might be a little hard to find, unless that block was available in earlier years with a carburetor (in which case it's a shoo-in)... but even if you can't find an earlier intake, it may not be too hard to make an adapter plate that'd fit the carb.

You'll need to deal with connecting the low-pressure fuel pump to that tank. One approach is to take the high-pressure pump out of the tank, rip its guts out, and use it as a big pickup tube for the external low-pressure pump.

Me, I love carbureted vehicles. I'd rather have carbureted than injected ANY day.

Do my 1996 gmc box van engine fuel injection or carburetor


Look.
If you see a fuel rail or a short-throat throttle body, it is fuel injected.
If you see a carburetor... well, I think you get the point :)
From the year (unless it is a non-U.S. model), it is most likely FUEL INJECTED.

Your picture won't come up. If you are getting oil in the air filter housing, check your pcv system (Positive Crankcase Ventilation). Your pcv valve may be plugged or not working.
And just so you know, it is not a carburetor. It is a throttle body assembly with throttle body injection. You have fuel injection with injectors mounted in the assembly-much more reliable than a carburetor.

Can a conversion be possible from fuel injector to a carburetor on a polo 1.6i


If it is throttle body fuel injection, it may be possible to use a carb...but, why would anyone want to? While economy (miles per gallon) might be similar, fuel injection is superior in all respects. A carb has a gazillion moving mechanical parts that eventually wear out, get out of adjustment, or need replaced. Throttle body injection has a lot fewer parts, will be more stable and reliable over the long term.
That's my opinion. I don't know how much problems you might encounter with fixing the wiring, but if you have an engine computer, it will be all the more difficult, if not near impossible. Another consideration is that you would need a lower volume fuel pump for a carburetor.
My advice would be to forget it and fix the fuel injection system.

2000 dodge ram diesel 2500 . What is a fuel injection pump mechnical failure? a fuel valve feedback circuit?


This usually happens when the lift pump gets worn and fuel pressure drops below 7lbs and the injection pump has to work harder by pulling in the fuel and will destroy the pump,your is probably a vp44 fuel injection pump it needs replaced and they are expensive 1200.00+ but also change the lift pump or change to a fass fuel system,if the lift pump went out and you replace the injection pump it will ruin it in a short time.
The injection pump is not an easy job to change or for a novice mechanic as it has to be set in time with the engine at top dead center,and then the whole fuel system needs to be bleed of air.

Check throttle position sensor (TPS) is a sensor used to monitor the position of the throttle. The sensor is usually a potentiometer, and therefore provides a variable resistance dependent upon the position of the valve. The sensor signal is used by the engine control unit (ECU) as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending upon the position of the throttle, and also depending on the rate of change of that position. For example, in fuel injected engines, in order to avoid stalling, extra fuel may be injected if the throttle is opened rapidly (mimicking the accelerator pump of carburetor systems). the cost about 50-75 bucks.

My 1984 toyota corolla ran out of gas now it wont idle


Quick explanation of your fuel system:

An automotive fuel system consists of everything between the fuel tank and the carburetor or fuel injection unit. This includes the tank itself, all the lines, one or more fuel filters, a fuel pump (mechanical, electric, or both), and the carburetor or fuel injection unit.
With the exception of the carburetor or fuel injection unit, the fuel system is quite simple in operation. Fuel is drawn or pumped from the tank through the fuel line by the fuel pump, which forces it through the fuel filter, and from there to the carburetor/injection unit where it is distributed to the cylinders.

So with that info...try first to clean your spark plugs.
Next, replace your fuel filter.
After that, depending on a carburetor/fuel injection, try an additive that cleans the injectors. For the carburetor, try a half of can of what is called "Seafoam". It comes in a metal can available everywhere, including Walmart. It is worth the $6-8 and also will "dry" out your fuel from water. Very good product.

After that, get back to us and let us know how your Toyota is running.

Not getting any fuel to thottle body


1st i would like to ask, is your car a carburetor type engine or an electronic fuel injected. if you have a carburetor and assuming your fuel pump is working properly, you may have a clog carburetor. just clean it and better replace your carburetor gasket and repair kit. this job is not a DIY, let an expert do it for you. if you have an electronic fuel injection, its more complicated situation coz EFI system are controlled by an ECM electronic control module. have your vehicle service by an autorize auto repair shop tha uses a scan tool or diagnostic tool to find fix the problem.
