Use a code scanner to check the engine diagnostic codes. If you see any problems fix that first. If there are no issues, check fuel pressure at the fuel rail test port. If the fuel pressure is low either at an idle or when driving under full power, check and/or replace the fuel filter.

use a noid light set to determine if pulse is going to the fuel injectors.

check your fuel filter, injectors, catalydic converter, if it has a Carb. check it

the computer and the ignition module give power to the injectors.

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.

To answer the question broadly, so long as you know that the problem is the injectors and not something else, i.e. lack of spark, there are several possible electrical reasons the injectors are not getting power:I am not an expert on the older Nissans, but the first items to check would be any fuses, circuit breakers, and/or relays in the circuit(s) containing the injectors. Should a relay be bad, the contact switch will not close, and electricity will not flow through the circuit, should a fuse be blown or a circuit breaker popped, no electricity will flow either.There could be a possible short to ground somewhere after the battery and before and switches, resistors, transistors, or the injectors themselves, causing the electricity to rout to a metal part of the vehicle before reaching the injectors.Check to see if any other circuits or electrical components are operating when they shouldn't, or if any circuits will not power down or turn off when they should. If this condition exists, then it is possible that the wires in the injectors' circuits are meshing with the wires of another circuit, causing the other circuit to operate improperly, and the injectors' curcuit to not have enough voltage to power them.Finally, be sure all resistors, transistors, switches, relays, etc. have the proper continuity or resistance.If you know someone who is electrically inclined, have them check the circuitry with a DMM (digital multimeter), or have an automotive technician ASE certified in automotive electronics check it out.

check your fuses if all good check to see if there is power going to the fuel pump if so then replace the pump

we should check the following things:- 1.we should check the connection of our computer with the CPU. 2.we should check if the power is not cut. 3.we should check its brightness and contrast.

i have a 92 mercury carpi i have fuel i have spark but will not start i do not have power to my injectors not sure where to start on how to get power please help

Check all your fuses first Then I would check for power at switch with a test light With key on you should have power on one side of switch .If you have power going in next step is to check with switch activated you should have power out . If you have power in and out of switch chances are motor is bad but you should check for power at motor also.Hope this helps.

rough idle,execsive smoke from exhaust ,low power could all be symptoms of bad injectors . also check the delivery pump pressure it could also cause the same symptoms

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.

you should check egr valve and check for a vacuum leak

1)Check your fuel filter.2)Check your fuel rail assembly for any leak for gas and a vacuum for the pressure.3)Check your power to your injectors if on power then go to your fuse/relay box look for the one for your fuel pump.Then go ahead and replaces your fuel pump should cost around $30.and$120.dollar

Where did you get the leaded gas that clogged up the catalytic convertor? When was the last time you cleaned the gunk out of the fuel injectors? How many miles does it have on it and have you maintained it according to the owners manual?


Check the fuse Check to see if you are getting power to the switch Check to see if you are getting power to the motors - if so motor is bad

to my knowledge there is no power steering filter i would check my power steering fluid level
