Isuzu trooper is making a ticking noise, what could it be.

SOURCE: 1999 Isuzu trooper wont start everything works

If you hear a click when the ignition is turned but no start its a high possibility that its the starter or the wiring going to and from the starter. Hope this helps! ~Derek~

Bad switch or someone has bypassed the switch, should shut off when you turn ignition switch off, my 94 does. HUNT

SOURCE: where is my oil pump

The oil pump is in the oil pan. the lifters will continue to tick until they are properly oiled. Be careful not to use to thick of oil as this will only make the pump work harder and could further damage your engine.

SOURCE: ticking noises from lifters but a louder ticking

Hi, i think the clicking is the vavles and I would recommend having a carbon cleaning done on your engine as well to help solve this irritating problem.

SOURCE: why does my isuzu trooper 3.5 run at 1600 revs

The idle is controlled by a TPS-throttle position sensor, and when it goes out, this is one of the signs, the other sign is that it will not idle. The TPS is located on the throttle body, and is attached with a couple of screws and has a plug in. I would recommend that you unplug, and replug the TPS before buying a new one, as they can lose connectivity. If that does not work, then I would recommend that you get a new one. You can pick one up at any auto parts store.
