youd need the NPR heavy truck, FSM book page on radio wiring

My 2002 isuzu npr diesel f14 ign/ecu fuse blows about 20 seconds after starting. The glow plugs are on the circuit. It's not a direct short to ground. I'm can't find the right wiring schematic.


first off
no country stated
the books are indexed by
country
year 2002
isuzu NPR heavy truck
ask Isuzu for matching FSM book at your dealer.>
factory service manual.

shorts
remove all loads on the feed F14.
then add them 1 by 1 until it blows. bingo. last add is shorted
id bet ecu and glows are not same feed
glows suck huge current
ecu, nill

join a read isuzu forum
or heavy truck?

maf can cause the problems you describe, but a maf code can also be caused by a backfire, check to make sure you have sufficient fuel and fuel pressure to the engine before you start replacing parts if not repair the problem clear the codes and ttry again
