Loss of power in your 1996 34L 4X4 Cleaned Injectors What should you check next?
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.
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…
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
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.
There is no injector relay. The fuel injectors have +12 volts on the pink wire all the time. The pink injector wire is fused by the 15 amp fuse in the divers side fuse panel. The 15 amp fuse gets its power from the ign switch. Check power at the injector with ignition on should be 12 volts. The injectors get their ground from the ECM located under glove box. If you have no power…
1988 mustang 5.0 liter how do i trouble shoot no power to fuel injectors I have spark but no power to the injectors....not getting any fuel and yes I have gas in the tank and the pump kicks 40psi?
Your 91 chev 305 engine was swapped for a 350 Are the fuel injectors the same or should they also be changed?
You have an 86 4wd truck z24 engine It got flooded with water you replaced the computer and cleaned and checked all grounds but the injectors do not pulse with no noid light response what could it be?
The ecu needs to know the engine is turning. Since this got wet too, the first item I would check is the cps, Crank Position sensor. If the cps is not working, the ecu doesn't know the engine is turning and the ecu will not send a signal for the injectors to fire. You have got some major troubleshooting ahead. Start with the computer relay and fuseable link, make sure there is power to the…
Check for a spark, if no spark check to see if the coil has a switching signal, if no switching signal check the crank sensor and associated wiring. If there is a spark, it's a fuel problem, check for live to injectors and an injector switching signal, if that's allright check power to the fuel pump and fuel pump amps draw.
You unplug the injector connector and install a noid light in the harness. Crank or start the engine and the light should blink if it is getting power. Reconnect the injector and using a stethoscope and place it on the injector and you should here a clicking noise. In all probability the injector should be working unless the nozzle is stopped up preventing the fuel from spraying.
What causes power loss hesitation on a 240sx 1.8T at 4500 to 600 rpm problem is worse when cold and full throttle?
I have an 89 240sx and had the same problem. After replacing the air filter, tune ups, and the fuel filter, i still had no luck. Then i checked the connectors on top of the fuel injectors and found them extremely corroded, I cleaned them and it has almost fixed the problem. To fix completely you need to get new ones if they are corroded, and maybe even some fuel injectors.
