SOURCE: no injector pulse

hello sir,

absence of ground pulse means there is some kind of shorting circuit in your control circuit.

which can make the ground pulse to get shorted there itself preventing it to reach the circuit properly.

thank you

SOURCE: wont stsrt

sounds very much like the coolant temp sensor
, this tells the pcm that the engine is cold, sometimes they fail and tell the pcm the car is at -40 degrees, the pcm then tries to compensate by keeping the injectors open for too long flooding the engine. the part is inexpensive, and normally easy to replace. It can be checked with a scan tool, or a volt/ohms tester,

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA

Hi Oillyspil 2004 Nissan hardbody 2 litre petrol. Injectors pulse only once evertime i crank engine I have spark at plugs


Sorry, can't find your vehicle in my US automotive database. Is your vehicle sold in the US? I doubt I'll be able to look up any info or wiring diagrams.

The basics, I'd want to see if your losing voltage or ground for your fuel injectors. If you have two wires at the fuel injector, one is probably voltage and the other is probably ground, the ground is usually controlled by the computer.
If the computer won't ground the fuel injector circuit, check the security system, and check for rpm signal.

Poor pulse on injectors


I don;t think it is your ECU. It sounds like you may have faulty wiring to your plugs. Did you change the wires? this might help.

1986.5 Nissan Hadrbody wont start.


2wd? 4wd? engine size? I think what you are referring to is the "fusible links" which are just big fuses inside of a covering that looks like its a wire. Hard to believe that a dealer tech doenst know whats under the hood of a truck they deal with everyday? These usually dont go out for no reason. there is a load on them that is too much. depending which one is bad, you need to ck that circuit for a short.

1987 nissan pathfinder wont crank or anything


FIRST TRY TO SEE IF THE FUSE AND RELAY ARE FUNCTIONING PROPERLY. IF THEY CHECK OUT THEN CHECK FOR SPARK AT EACH ONE OF THE SPARK PLUGS. IF YOU ARE GETTING SPARK THEN I WOULD REPLACE THE CRANKSHAFT POSITION SENSOR. THIS DEVICE IS RESPONSIBLE FOR OPENING INJECTORS AND SPARK PULSE THROUGH THE COMPUTER. HOPE THIS HELPS. PLEASE LET ME KNOW. BEST OF LUCK

I HAVE A NISSAN d21 2.4L 1987 hardbody pick up as im driving when i let up on the gas pedal it seems to stumble just a little bit then it seems fine after that ???


Sounds like it could be faulty fuel injectors. (unless of course, it's carburated, then it'd be a poorly adjusted float)

1995 FORD EXPLORER 4X4 6 CYL 4 DOOR WONT START


Fords have inertia fuel cut off switch. You need to check that first. If you dont have fuel. If you have fuel and no spark you need to check for inj pulse to injector. Make sure no fuses are blown. If no spark and no injector pulse then replace cranksensor.
