SOURCE: Oxygen Sensor on '99 Isuzu Trooper

The O2 sensor is on the engine side (up stream) before the catalytic converter in the exhaust pipe, it is barrel shaped about the size of a jumbo magic marker.

Was it lined up right as the trigger point for the sensor is important.Is the fly wheel fitted one position only that the bolt holes line up or will it fit no matter which position it bolts up Line up the flywheel trigger with the sensor after you have put the engine to Top Dead Centre.Put at tdc and see if the trigger and sensor are together.

It should do unless the gauges or boken/loose wire was the original fault

SOURCE: manual for time belt replacemant Isuzu Trooper

4JX1 diesel engine has a belt . 4JGE is a different engine completely. To change it set #1 on tdc fireing stroke using the mark on the back lip of the crank pulley (sit it at 12'oclock) and see the mark on the camshaft bearing matches the notch on the pulley .Ignore the marks on the lower belt pulley.
Tensioner and cover removal/replacement is standard and the chnage period is 60,000 miles.

2000 isuzu trooper: OBD-II Trouble Code: P0401 Insufficient EGR F


Your SUV is really giving you a hard time, lol. Sorry but I've had those days too.
I would try to check if you have blocked EGR passages. If ok check for restricted MAP sensor vacuum hose/passage or restricted exhaust. I know you replaced the CAT but if the muffler is blocked then there would still be a restriction. Also check the wiring and connection to the MAP sensor.

 An electronic throttle control (ETC) system to control an idle speed of an engine includes an accessory that increases a load on the engine and a controller that generates an idle request signal based on the increased load.
Your going to have to get your Isuzu scaned. the code is P1511 which is a defective ECT. Sorry I can't help you with more but it sounds like this may be the problem. 
Good luck and hope this helps

My 1999 Isuzu Trooper


Troopergal is probably right. It does sound like an electrical problem. However with an electrical problem it normally won't always start again right away. Another possibility is you have a clogged fuel filter. This is an easy one to fix. They are small in line placic filters in the fuel line and are easy to replace. They only cost a couple of dollars and are available at any spares shop.
