Question about 1986 Nissan 300ZX

1 Answer

I am working on a '86 300zx that will die randomly. It dies less often while idleing however if you attempt to accelerate hard it dies. The car will then sometimes fail to start. I can hear the fuel pump engaging and will continue to run for a second or two after dying. Although the pump doesn't kick on every time you turn the key from off to on. Any suggestions as to what might be malfunctioning?

How dose it die dose it sputter or just die out right. have the mass air flow checked. I would sugest to invest in a chilitons repair manual for the year and model. You might even get lucky and get one for you local libery.

    well it is defentily electrical I dont think it would be the efi becose there would be some risudal fule the would make it sputter I would check the cam sensior pick up
    Unfortanly the only thing you can do is just start reaplacing parts. I had a 85 280zx and I took it to the dealer and had them run a digonestic on it and they said it was in the elect ignition but only way was to just start reaplacing parts will it die at idel if so pull a plug wire and watch the fire through another plug hooked into it dose the fire get weaker just befor it dies or dose it just shut off I would definetly look into the cam pickup first becouse if it just dies like you turned the motor off it is in the ignition if it was the efi it would run out of fuel but there would be some in the cylinders to sputter for a second or so You shold be able to ome out some of the sensiors through the book if your book dose not haveit you might find some online I will try and look for some tonight through googel and such and get back to you through here K

Replaced egr valve assembly now dies when rpms drop


I guess if the egr isn't closing and is stuck open you could have these symptoms it would also have random cylinder misfires, stalling, rough idle, hard brake pedal... And would run ok at higher rpm. EGR doesn't work at idle so if it was staying open could cause you issues. The other thing that may be an issue as you come to an idle is the idle air control valve (IAC). The iac allows air to bypass the throttle plate upon start up declaration and at idle since the throttle plate is close at these particular time. If it happens to be stuck shut then no air would by pass the throttle and there wouldn't be air for combustion to occur and maintain engine running smoothly. Some thing to look at.

Jeep 2002 grand cherokee dies unless i keep foot on the gas...


The idle relearn needs reset. Keep your foot on the gas at about 900 rpm. Make it idle for about 5-6 minutes. Slowly ease up on the gas until it will idle on it's own, it might take a while. After you get it to idle, it might be idling real low, but on its own, Let it sit and idle until for 20 minutes. After that it should be back to normal. You will have to do this every time you have the battery unhooked for a while.

Trouble starting, engine won't catch


Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too

ENGINE SPUTTER AND DIES ON ACCELERATION


check your fuel filter, take an air compressor and blow air through the "in" end if no or little air is coming through then just replace the filter, if fuel filter is ok then try a fuel additive to clean your injectors which are a very common problem when the engine gets gunky build up on them
