Can a bad fuel injector cause a Mustang to misfire?
A faulty fuel injector will cause your Mustang to misfire. The fuel injectors will suffer if the car owner is always late on maintenance. Along with the embarrassing engine misfires, bad injectors could cause rough idle, poor fuel consumption, poor performance, starting issues, and engine knocking.
How are fuel injectors controlled in a Ford?
This is regulated through sensors, your Ford’s engine computer, and the injectors. The fuel injectors are electronically controlled by the car’s engine control unit.
What’s the horsepower limit on a Mustang 4.6?
4.6L Mustang Engine Power Limits. The power limit on the 4.6 engine can vary based on the production type and year of manufacture. On all 4.6 based engines though, the weak link is primarily the connecting rods. For 4.6 engines with 2 valve heads (2 valves per cylinder), the power limit is around 400 rwhp.
How does the fuel system work on a Ford Mustang?
The fuel system is a major part of your Ford Mustang GT’s operation. Learn how to diagnose it here. This article applies to the Ford Mustang GT (1996-2004). The fuel system works with your electrical system and intake system to make your Ford Mustang GT the enjoyable ride that it is.
Can a Ford Mustang have a bad fuel injector?
Fuel injectors can go the life of a modern vehicle with little to no trouble at all. That being said, bad fuel injectors are one of the more common issues that happen to any vehicle (Ford Mustang included). There’s always more than one, and one going bad is enough to make a noticeable impact on the drivability of the vehicle.

When did they start using fuel injection in Mustangs?
As the progression of engines has continued, the higher power levels have demanded a larger fuel delivery system. In order to fuel the new power, larger, newer style fuel injectors started becoming a vital part of an engine setup. The first year of modern fuel injection in a production mustang was 1986. They came with 19lb/hr injectors.
Where is the fuel pump located in a Mustang?
It is located behind the inner lining of the trunk on the driver side. For people using bigger fuel pumps that demand more power, it is common to use a modified FPDM or dual FPDMs.

How does the fuel pressure work in a Mustang?
It varies the fuel pressure by being connected to manifold pressure via a vacuum connection. It also utilizes an internal diaphragm to control the pressure. At idle, the engine is in a manifold vacuum situation and the fuel pressure is around -9psi to manifold pressure ratio.
How to test a no start fuel pump?
One is to check that the fuel pump is functioning and supplying the correct amount of pressure. The other test is making sure that the PCM is activating the fuel injectors. This can easily be accomplished by using a Noid Light to check for these On/Off activation pulses the PCM sends to the injectors. CASE 1: Fuel pressure is at specification.
