2004 Isuzu Ascender not cranking

Check your mega fuse. Hope you didn't try and jump it off the fuse box terminal next to the battery. Some people do this, will blow the mega fuse every time. Mega fuse is located in front of fuse box, held in by 2 bolts. Cheap fix if this is it.

2004 Isuzu Ascender 6 cyl. Battery died, replaced

Did you check the mega fuse in front of the battery? 125 AMP fuse. A lot of times people will jump the battery at that post and blow that fuse. It's bolted on right in front of battery, about 3" long.

Hello, how can I resolve an error code B0001 for a 2004 Isuzu Ascender with a 4.2L engine? Thank you!

There are no results for this error, scan and see if a different error pops up. You can go to any auto parts store to get it scanned as long as the check engine light is on. Advanced Auto etc, Auto zone. God Bless! Its free!

Does 2004 ascender have a emergency fuel shut off that is triggered by accidents

no it's not a ford (or the odd mazda under the ford yoke)\ join are Isuzu form and end the lies.. ? LOL ! next. William , instead of guessing parts that do not exist. do post symptoms. and we can do tests. and find TRUE CAUSES. now let me ask for you, (pretend you said) "do cars have fuel cuts, in a crash." SURE! surprise all do.!!! ALL ! but all work differently. see? it's also a law here. in the usa. (have DOT chapter and verse) on most cars gas, the ECU or PCM on all EFI cars here monitor spark (uses many way, more later) and when that happens, say slamming into rear of semi truck say crushing your engine,flat. the ECU sees spark go dead. and or RPM goes to zero, (which ever wins first) and then cuts fuel 1 or 2 ways. it cuts injection first in most cases, best plan 1. (no people on fire) then may cut the fuel pump relay, about 1/2 don't. what does this mean,? it means if spark ok and the ECU is not barfffing DTC codes about spark,,cmp or ckp bad the IT's THE wrong tree to bark up. there is no inertial valve, only on FORDs. 99.% almost ivory soap pure, LOL now ill try the impossible you say, car cranks, but will not start. then I say is spark good? you test it and its ok and timed right , if timing way off cam slipped. then we try test fuel (spark engine run for 1 to 3 seconds) yes, good, see all is good lost fueling or maybe flooded so we check fuel pressure, next. need video if scotty, here 100s posted this. https://www.youtube.com/watch?v=064Ilsz8Fzg&NR=1&feature=fvwp or its just not doing tuneups trying to run spark plugs for 300k miles?????? and filters?????????? this last 3 lines is 100 years old now, and is 99% cause (stats) of most cars running and misfiring then stalling and the floodiing guess what, are you spark tips soaked in fuel>??? are they relics?

My tail lights on a 2004 Isuzu Ascender aren't working. Where would that fuse be located at

Depends on which specific lights you are referring too ..parking lights or brake lights? If parking lights then are the front ones working? If they are then it's not thefuse as they are all on the same circuit

2004 Isuzu Ascender keeps misfiring,losing acceleration and sputtering when stopped at a red light or stop sign. Changed camshaft position censor.Found oil all over the threads on two plugs

The first thing i would do is replace plugs after checking if wires areok. I thought my fuel pump was going out but all it was, was bad plugs and wires. i replaced them and my gas mileage went up 50%.

Not sure what your question is, but if you have the I6 engine use AC Delco 41-103 plugs.

I need to replace the water pump on my 2004 isuzu

Hi,
Tipping my hat to you... I would recommend going to an auto parts store like Autozone or O'Reilly and purchasing a Chilton repair manual, specific to your model. I always think it's a good idea to own a light repair manual if you're going to keep the car a while.
Good luck with the project! You can do it!!
