Where to find engine relay in a isuzu npr200 1993

The first thing to do is always reset the security system and engine immobilizer. If that doesn't work, you find a local auto electrician. Their pro grade scan tool computer will interrogate the electrical systems and check for DTCs.

The roll over safety switch may have to be reset. It is in series with fuel pump relay interlock circuit.

not tuned up?

flooding , try cranking WOT to clear all flooding.
when wont start, check for spark,????
if diesel, then try posting engine type. exact isuzu name.
or if really savvy? the country first.

fuel pump relay should be in the engine compartment on or near the fuse box

The wire that runs to the glo-plugs comes from the relay and as it is a heavy gauge wire (colour coded ) try tracing it back to a relay. IT may be completely separate to all the others.

Just solved this problem on our 2004 Isuzu Ascender. It was a bad relay located in the fuse/relay box which can be found inside the engine compartment. The relay is number 46 (HDM) on the diagram located on the inside cover of the fuse/relay box lid.

There are actually two of the same relays side by side in the fuse/relay box. To be sure this is the problem you can remove the relay from slot 45 and put in 46, the headlights should come on and stay on. Of course you will need to replace the relay which can be purchased and most GM/Chevy. The part number is: 15016745. I paid $52 for mine.

Oh, and be sure you use solid state relays only. The afore mentioned part number is a solid state relay.

check you connection on battery and the wire that runs from battery to starter wiggle it while some one is trying to start the car.any luck let us know
