4JX1 engine cut off while test drive after oiland filter change and not starting

Bought it recently from japan.it was running perfectly when due changed oil and filter. on test run running perfrctly for 15 minutes and then engine cut off while it was rolling and is not starting again. there was check engine light for 5minutes before it went silent. the other thing which i noticed was a noise of vaccum like coke bottle opening when we swithched off engine while testing. we tried to figure out but could not. i thought that this noise could be normal as i never swithched off engine with bonnet open and myself standing outside. i tried to pump fuel filter and tried but it is cranking nicely but not starting. please advise.

That pop noise is ok just the flap in the throttle body coming open when the car stops .
The engine may have stopped because its low on oil so the oil pump for the injectors wont work - takes about 7 u.s. quarts of 5/30 fully synthetic oil at service time to run right.
It can also stop if the pressure sensor in the injector rail packs up or the oil pick up pipe for the injector system falls off due to cracking the mount .

Not sure what 4jx1 means. What vehicle are you working on? If engine was fine until you changed oil, and you did nothing but change oil, you have a real mystery. Did you also change oil filter? Are you absolutely sure the new filter is the correct one for your engine AND that it's not some cheap walmart filter which could be the whole problem? I have seen a few filters which were made wrong from the factory.

I have a Mazda MPV 2003, i bought from japan, 7 months ago, this van was running well until two days ago, it stsrts and cut off, starts again and while driving it is losing power then it will speed up


Before any diagnostics, I would run a tank of gas with a bottle of fuel dryer and injector cleaner to ensure that the engine racing isn't resulting from moisture and clogged injectors.

You should not have changed perfectly good parts,
without any knowledge of the system your working on

You need to use professional tools to test the vehicle, to first
find a problem,then component test parts like you changed

Only parts that fail a test get replaced

Your out of knowledge,not ideas

Your living in the 1960's or 70's when you could afford the
parts & replace them in a wish & hope strategy & maybe fix
a problem,not today,have to know how to test a vehicle

I cannot start my isuzu bighorn w/4jx1 engine. we already changed the turbo but still it emits too much smoke in the exhaust and after a while the engine goes wild and we cannot turn it off in the ign


Its a diesel and its running away so do not try to start till you do the following and yes i know i will be amolished for being a cowboy by the other experts but what you do is to make a gasket for the EGR valve from a coca cola can and seal it off if you dont it may run away and blow itself to pieces .If you do this then it run as normal as the older trucks never had these thing fitted and they all run ok in my day ,exactly whats wron i couldnt tell you without my head under the bonnet but do as i say and it run perfectly
