Why dont my fuel injectors pulsate on my 1991 ford mustang lx 5.0


The firing order is shown below from Jeff back in April 2011.
The order is 1-3-7-2-6-5-4-8 and cylinder one is front passenger side of engine.
I would agree with the person who answered your question earlier, all of the injectors are powered by the same red wire, half of them are grounded on one circuit and the other half on a second circuit. Both circuits come from the computer.
So if you have spark the ignition module is working, which would point to the computer being the problem.

Need firing order for 89 5.0 ho gt mustang


Firing order should be 1-3-7-2-6-5-4-8 with number one being front passenger side and number 5 being front driver side.
If the firing order is off it should backfire.

What is the spark plug firing order for a 1989 Ford Bronco with a 302 Cu. In. V8 engine?


There are three kinds of 302s made from 1982-2001. 5.0L HO This engine was used in 1983-1995 Mustangs, Mark VII Lincolns, and some T-birds and Cougars. All Explorer 5.0L engines are 5.0L HO engines as well. They use the 351W firing order, 1-3-7-2-6-5-4-8. Except for the 1983-84 Mustangs, all of these engines are roller cam equipped. They use a reverse rotation water pump and front cover. The 1994-5 Mustang and all Explorers use a unique front cover and water pump. 5.0L Full Size Car This engine was used in 1982-1990 Crown Victoria and Grand Marquis. They use the 289-302 firing order, 1-5-4-2-6-3-7-8. Most of these cars are not roller cam equipped, however sometime in the early 1990s they started using roller cams but retained the 302 firing order. They use a standard (clockwise) rotation water pump and front cover. 5.0L Truck (except Explorer) These engines are similar to the Full Size Car engines, except they use different intake manifolds and camshaft profiles. They also use the 289-302 firing order, 1-5-4-2-6-3-7-8. They also began using roller cams sometime in the early 1990s. They use a reverse rotation water pump and front cover.

Good Luck

Not all spark plugs firen


You check the right firing order?

1991 Ford Mustang 2.3 liter SOHC L4

1991 Ford Mustang 5.0 liter V-8 HO

Also, need check the PCM for someone short; sometimes this is the reason it wasn't sending a signal to the coil. You have constant power at the coil but the ground signal doesn't fluctuate from on to off while the engine is cranking. If the hall effects switch in the distributor is bad it won't tell the PCM when to fire the coil and the hall effect switch also operates the tachometer. So if this switch is bad the tach and the coil would not work.

Good luck.
