check the fuses
the computer and the ignition module give power to the injectors.
Are you getting power to the system?
First, run a compression check. If that's not it it could be ignition or injectors.
Check the camshaft sensor. If the sensor is bad or not getting power, then the engine will not fire and the injector will not get a signal.
it will spit and sputter or miss or just not have no power at all very sluggish

The fuel injectors do have a fuse, usually found in your underhood Fuse Box. Using a Noid light can let you know if the injector is receiving a power and Ground.
Injectors that have a resistor in the power supply are called
Replace you ignition module, It controls both spark and power to the injectors. You can have spark but the module may be bad and not giving power to the injectors and the vehicle will not run.
try checking the amount of pressure your injectors is getting under the hood i believe they should be getting 40 pounds if they are getting incorrect pressure it will affect ur power
Not much info to go on but, do a fuel pressure test to se if you are getting the proper fuel pressure to the injectors. Year, make, model and engine size would help us help you.
