An Ohm reading is the amount of resistance through a fuel injector. A fuel injector is a solonoid that controls fuel delivery. Inside the injector, there is a coil of wire. When you measure the Ohms across the injector, you are checking the amount of resistance in that coil of wire. Each injector manufacturer has their own acceptable measurement, so check with them for proper readings.

Take off the upper intake, the regulator is on the backside of the fuel injector unit spider.
A fuel injector's current draw, measured in amps, is a function of the fuel injector's actual impedance. Your answer is then necessarily dependent upon the impedance of your injectors. To determine your injector's draw, simply divide voltage by ohms. That is, given a 12v circuit and an injector with 12 ohms resistance, the draw is 1 amp (12 divided by 1).
don't no ,thats why i'm asking
leaking injector or bad o2 sensor
Fuel pump is in the gas tank and it is not cheap.
If the fuel injectors on your 1991 Jaguar XJS are not firing, first check the electrical connections and wiring to ensure they are intact and not corroded. Next, inspect the fuel injector relay and the engine control unit (ECU) for faults, as they play a crucial role in injector operation. Additionally, test the injectors for resistance with a multimeter; if they are faulty, they may need to be replaced. If the issue persists, consider consulting a professional mechanic for a thorough diagnosis.
if there is fuel to the throttle body injector then test the injector itself. is there a pulse from the computer? use a noid light to see pulse. if so does the injector has high resistance? (resistance can be looked up on-line or at your local auto parts store) resistance is the amount of amperage electricity needs to go through something. that's why corrosion on the battery can cause it to fail or the alternator to fail. if all these tests fail, inspect for blockage between the injector and inlet to the TBI unit.
A Lincoln Mark VIII fuel injector typically has an impedance of around 12 to 16 ohms. It's important to check the specific specifications for the model year and type of injector, as variations may exist. If you're measuring resistance, ensure the injector is disconnected from the power source for an accurate reading.
if you do not have spark you will not have fuel check coil module and ignition pick up coil.
