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.

I have no gas to fuel injectors but have it at gas distubution box

Check and make sure you have + battery voltage to one side of the injector's, the other is grounded by the computer to open and close the injector (called "PULSE"), if no voltage at injector check the fuse for the system or fuse link (refer to wiring diagram's for system). Repair any shorts if fuse is popped. If you wish to access the wiring diagram's you can pay to download them here. Sorry but Fixya doesn't have factory manuals or wiring diagrams.

Free one's here Enter vehicle info. year ,make , model and engine . Under system click on engine then under subsystem click on fuel controls . Click the search button then the blue link. Scroll down to diagram # 6 . Coil circuits . Pink with black trace - B+ voltage , black is ground , brown is signal ground in the PCM - computer . orange with white trace is coil trigger signal from the PCM . Diagram #9 is fuel injector electrical circuits . Test power and grounds . You probably have a bad coil or injector ,wiring issue , or a bad driver inside the PCM . If the PCM needs to be replaced it will need programming , dealer only .

I have a 94 chevy van g20. it has the 5.7L TBI. im having an issue with getting to much fuel to one of the injectors. If i turn the key one click foward to the on position, the driver side injector starts...

You have a wiring problem on the control side wire . One wire will have B+ voltage the other goes to the PCM- engine computer . The engine computer suppy's a ground when triggered by cam sensor . Your problem is you have a bare wire touching ground making the injector fire all the time the key is on ! Check the wiring harness from the injector to the PCM for rubbed through spots !
The PCM must be inside the passenger compartment under the right side dash or behind the right kick panel . Here is a web site for free wiring diagrams . Enter vehicle info. year , make , model and engine size . Under system click on engine ,then under subsystem click on fuel controls . Click on the search button , then the second blue link. Second diagram down is fuel injector electrical circuit. Dark green wire is the controlled ground . That is the wire to check .
