Sounds like an injector problem, will have to test with a noid light, if its getting power then injector is bad.

Engine bucks and backfires through throttle body under acceleration

for an engine to backfire through the throttle body means that the inlet valve is still open when spark occurs . That means that the timing is too far advanced . IT may also mean that the tappet clearance is out if manual adjustment or the hydraulic followers are pumping up and holding the valves slightly open especially at revs.

Fuel metering device location ?

Hi. Not exactly sure what your looking for ..... The fuel is delivered to the engine via a fuel rail and each cylinder has a injector to deliver fuel to that cylinder.

Fuel is pumped into the fuel rail at 35 psi from a pump in the fuel tank.....don't worry, never heard of one causing a fire. There's not enough air in the gas tank to support a flame.

There is also a 'throttle body' to allow air to enter the engine but iit is not like an old carburettor also delivered fuel.

If you look in the engine bay you will see the cables that operate the throttle body. there will be two cables, one for the throttle controlled by the drivers pedal and one cable operated by the cruise control.

Hope this is some help.

Fuel Injection Problem

Is your cat. convertor blocking up? If it is this condition, it could very well be the problem. Disconnect the convertor start the car & see if it takes the gas well. If it does, change the cat. convertor. Good luck!

Car wont start, install new fuel pump ,if u dump little gas in carb will run for a few seconds. ALSO THIS CAR SAT FOR YEARS NOT RUNNING

OK, first, let's clarify one point. Your 1986 Chevrolet Nova does not have a carburator, it is equipped with Throttle-body Fuel Injection.

You should be able to look into the throttle body and see fuel spraying from the fuel ijector while you are cranking the engine over. If not, then there is a whole list of things that could be causing the fuel to not spray. Here are some of the possibilities:

Low fuel pressure (for several possible reasons)
no B+ feed to injector (for several possible reasons)
bad crank sensor
bad PCM
broken injector wires
bad injector

If it runs with fuel poured down the throttle-body, it is definitely a fuel-delivery/fuel injection problem.

Car won't start once in a while, mostly after it sit's a few days. it cranks ok and almost starts. good spark, and has fuel but I can't test fuel pre. if I pull the lines from the tank it starts and runs...

your on the right track,you need three things to run an engine spark fuel and air,you can test your pump another way its primitive take 2+2 carb cleaner get access to your throttle body have someone try starting the engine while another sprays the carburetor cleaner into the throttle body if it runs while you spray and then stops when you dont your fuel pump is the problem.Chrysler is know for this fuel pump problem.
