Not getting fuel to motor


You can check the injector circuit with a test light. Have you verified no fuel is coming out of bottom of injectors, when the engine is cranking over? Use a flashlight, looking down the throttle body.

Ground a test light lead to a good ground. Pull injector connectors off, and turn key to on The white wire with red stripe is the power wire to both injectors, it is hot anytime key is on. The wire splices off to both injectors. If power is good, check the ground side of circuit: place the test light clip on the POSITIVE post of battery, and put probe into the ground terminal of the injector connector-the black wire. Now have someone cranking the engine over-the test light should be blinking. Every time it blinks, the computer is repeatedly grounding the injector circuit (internally) and this causes the injector "pulse"- turning the injector on for fuel to spray out. If both tests are good (power with key on, and blinking ground with engine cranking) the injector circuit is working as it should. If no power, check computer for power in-check the main relay, for one.
As for the injectors themselves, not likely both would go out at same time, but only way to test them on the vehicle is to put an ohm meter across the terminals and check resistance. Both should be similar, with low ohms showing, somewhere on the order of 2- 10 ohms, I don't know the specs for Nissan-check with the dealer.
Good luck, let me know what you find out.
To verify the injectors or the injector circuit is the problem, try a little starting fluid down the throttle body, or even carburetor cleaner. If the engine fires and runs a few seconds, then you know injectors or circuit is the problem.

82 280zx. Replaced fuel injector. Now car will not start, What would case this?


Well did you try to start it a few times, after draining the fuel rail it will take a few times to purge out the air and fill lines with fuel. make sure that all connections are on and tight , double check your work and look for any connections that may have been left unhooked.

All you have to is check if the fuse or relay are working. If they are, your injectors should be replaced. In the future, use a fuel injector/ carburetor cleaner after every fill up.

#1 Spark plug is no burning fuel.


Either your timing chain has jumped a cog, or a valve is stuck or burnt. Best way to check the timing is with a timing light. If the mark jumps all over the place, your chain is no good. To check the valve, do a compression test. Good luck. Let me know how you make out.

Fuel injectors won't open


Wow! an '82. Nifty. Yes, it could be a grounding problem. The older systems used injectors that draw a lot of current. Especially check grounding between the fuel 'computer' box and the engine. Physically/visually check terminals or use a light bulb tester. A volt-ohmmeter is not reliable when checking high current circuits because it doesn't demand high current flow.

I saw the exact type of thing on an older BMW not long ago.
