Use a temperature checking device on the exhaust ports or pipes after you have ran the engine (about 5 minute's) to identify the cylinder in question, It will be cooler. If the injector is electrically activated use a noid light or volt meter to check the signal at the connector to the injector. It is a pulsed signal.
Bad fuel pump, clogged or broken fuel lines, or if it is fuel injected it could be bad fuel injectors.
Bad fuel line? Bad fuel filter? Bad fuel tank? Bad throttle body? Bad injectors?
Possible reasons the fuel injectors are not working: Faulty ECM (engine control module, computer) Faulty fuel injector(s). Fuel injectors clogged. Insufficient fuel pressure. Bad Ground. Faulty wiring otherwise.
you may have bad injectors, or not enough fuel pressure
Bad fuel filter or clogged fuel injectors
bad fuel injectors, bad timing, bad spark plugs and wires, clogged catalytic converter.
Bad as in dirty would simply supply unfiltered fuel to the injectors resulting in misfiring,hard starting and uneven and generally bad acceleration.Bad as in faulty could lead to fuel starvation,motor won't start, rev,cut out etc. no, supply unfiltered gas to the injectors? its a restriction, meaning no or very little gas to injectors, low or no fuel pressure
Check the fuel injectors . one or more are bad or going bad.
Switch the electrical connections between the two injectors and see if the same one is still bad or if the problem switched to the other one. If the same one is bad, you have a bad injector.
You either have bad fuel injectors or your fuel pressure regulator has gone bad
A clogged fuel filter, bad fuel pump or the fuel line is blocked/damaged. What about a fuel relay fuse?
Bad fuel injectors?Weak fuel pump?Bad fuel filter?
