SOURCE: no power tp the fuel pump, injectors not pulsing, no fuel.

Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.

SOURCE: 90 k1500 tbi no fuel from injectors

from the sounds of it its going to be one of 3 things 1) the injector is bad or 2) there is no power getting to the injector 3) bad relay switch.

1) to find out if the injector is good. pull the injector out and with some wire ground one side and touch the other side to your battery, every time you tap the wire to the bat you should here the injector click..

2) if injector is good get a test light and test to see if power is coming out of the wires that go to injector( on some vehicles you have to have the motor turning over befor power is sent through wire, so have someone turn the key while you check the wires with test light)

Lincoln L's V6 no fire no fuel wont start


If your missing spark--fuel--injector pulse, I check for rpm signal, that comes from crank sensor. What is year and model? Don't replace anything unless your testing points in that direction.

How long since tune-up? Any applicable trouble codes?

Car is turning over but not getting fuel ideas anyone thanks


There is not much information for a good answer.
  1. Fuel filter clogged
  2. fuel pump not working [fuse,bad pump,broken wire etc]
  3. computer not telling the pump or injectors to work [should set a code]
  4. dirty injectors

88 chevy 350 with no fuel pump and no injector pulse


The fuel pump circuit and injector circuits are fed by two different fuses.
The fuel pump relay and injectors are controlled by the computer. Have you checked both ECM fuses for power ?

We can not understand why it cant get fuel to the injectors


Have you tested out the fuel pump? check for plugged fuel filter?
plugged fuel lines to the fuel rail, injection pulse at the injectors? power to the fuel pump relay? grounds needed to make certain systems work must check those also. get a wiring diagram of the fuel supply system and back trace all the wiring and see if you have power and ground and signal.

No power to fuel pump no hum when key on and inj not pulsing


Fuel Pump Relay Circuit...
There is an Oil pressure switch in this circuit that disallows the relay to complete the power supply to the fuel pump. It is for safety purposes , it senses engine oil pressure upon cranking of the engine and then completes the ground circuit to close the relay sending voltage to the fuel pump at start up, and also functions as an engine kill if you loose oil pressure opening the ground circuit which in turn opens the contacts in the relay shutting off the power to the fuel pump.... Invest in a vehicle specific repair manual with wire diagrams... hope this helps..

1993 s10 2.8 tbi the fuel pump fails to pressurize when the key is tunred on, and i have to fuel injector pulse. when a jumper wire is attached i can pressurize the pump but i still have no injector pulse.


There needs to be 60 PSI of fuel pressure in the system to have the fuel injectors to work. There is also a fuel pump relay on the fire wall just left to the brake booster, There is two relays there, i just can not remember which relay is which but try switching the relays with one another. Also check the fuses to the fuel pump and ECM, and the fuel pressure from the shredder valve. Good luck and keep me posted, not a bad Idea to also replace the fuel filter, and that is located at the inside frame rail under the drivers side.

Inside the distributor and on the ignition module (7 pin) one of the wires to the camshaft pick-up had pushed out of the connector when I hooked up the new module. I reinserted the wire and problem was solved.
