Engine will not start after changing battery in 2004 Isuzu Rodeo

I own a 2004 Isuzu Rodeo 2WD ute. I had new keys cut after loosing the original key, battery went flat while at locksmith from sitting waiting for particulars from holden. Tow started ute, started for approx. 2 weeks, would not start, so fitted new battery. Fuses fine. Wondered if there is a sequence I need to go through to get engine to start. Tried fords idea of turning ignition on and left for 30 sec. before trying to start - would not start. Have checked the fuel filter - it is fine. Any suggestions? Thank you.

Get yourself a can of starting fluid spray, and spray NO MORE than a two second burst into the air intake after removing the filter. Then crank it. If it fires (very briefly), your problem is low or no fuel delivery to the engine.

    Hook it up to a scanner and view the information. It will tell you if it is in antithieft mode or if the sensors are not responding. You possibly could have reversed the power source and done damage to the electronics.

"when the fuel pump kicks....it makes a very short duration sound....you can hear it....but in seconds it will be gone......as gasoline has made its way to the engine.........

if you cant hear any noise from the fuel pump......it could be that the fuel pump realy is bad........if you happen to change the relay....and it still does not work.....then it is the fuel pump. that is fried.......

about the water.....i am not shure......unless there was water in the gasoline itself....or somebody put water in there in purpose....

hope this helps...

SOURCE: reprogramming remote and key

if its early 05 round heart shaped remote it needs programming into system at dealer with Tech2
later 05 to 07 had square (rectangle) shaped remote
1.2 ID Code Additional Registration
Note: This procedure will add additional remotes to the Keyless Entry Control Units memory. A total of 4 remote transmitters may be programmed into the Keyless Entry Control Units memory. When a total of registered and newly registered remotes exceed 4, the oldest one shall be erased.
Step Action
1 Note: Make sure that all the doors are closed and unlocked. Insert the ignition key into the ignition switch.
Open the driver's side door.
2 Turn the Ignition key to the “ON” position and then to the “LOCK” position three times
(The key should remain in the “LOCK” position)
Note: This step must be carried out within five seconds.
3 “CLOSE” and “OPEN” the driver’s doors once (Leaving the driver’s door in the “OPEN” position)
Note: This step must be carried out within five seconds after step 2 is completed.
4 Wait for 8 seconds (This wait time is critical)
5 Turn the Ignition key “ON” and then to the “LOCK” position once and turn key to the “ON” position (The key should remain in the “ON” position)
OR on/lock once
Note: This step must be carried out eight seconds after step 3 is completed.
6 “CLOSE” the driver’s door
The HAZARD lights should flash 3 times (This acknowledges the Keyless Entry Control Unit has entered programming mode)
7 Operate the lock or unlock button of the transmitters to be programmed; a flash of the HAZARD lights indicates the remote has been successfully programmed into the control unit
8 The HAZARD lights will flash approx 4 seconds after pressing the remote button to indicate the Keyless Entry Control Unit has exited programming mode.

SOURCE: 991 Isuzu 2.6l petrol runninf problem!

I realise you have probably solved this problem by now so sorry for the late news mate . Had a similar prob and it turned out to be an alternator malfunction . I replace the brushes and off she went . These things send voltage from the alt . to a fuel pump relay or whatever so the pump wont run if the eng isn't (or the alt isn't outputting any voltage.) . Hope you already had it sorted . But I hope this helps if not . Cheers Simon .

SOURCE: About once a week my 2004 Isuzu Rodeo will totally

the lights come on and the power steering goes because the engine has stalled while you are driving. it is the exact same condition as when you turn the key to the "on" position w/out actually starting the engine (all the same lights will be on and no steering because engine not running).
as for why this happens...sadly there are too many possibilities to usefully list here.
This is the basic equation for why your engine runs:
fuel + spark + compression = a running engine
The fact that your engine usually works means you can discount the compression piece of that equation.
This leaves fuel and spark. If loss of spark is the cause of the stalling, it is almost definitely in the primary side of the ignition system which means: don't go get a 'tune-up'. Tune-ups almost never-ever-ever fix driveability problems. The primary side of the ignition system consists of the crankshaft position sensor, camshaft position sensor and engine computer...to name a few things.
It is also possible you are losing fuel pressure intermittently, which could be due to a failing fuel pump, but this is an unusual presentation. Typically they are found to be bad when you try to start it up initially rather than **** out in the middle of running.
Then again, this whole thing could very possibly just be due to a loose wire connection in a really unfortunate place. Impossible to tell from here, so you'll probably have to settle with taking it in somewhere. I will say this: don't waste time/money taking it to a shop until it absolutely will not start up again. Shops can't diagnose a problem unless it actually has the problem while they are looking at it. good luck

SOURCE: my 96 Isuzu rodeo won't start and key is stuck in ignition

either that or the ignition switch itself is binding up

My check 4 wheel drive light stays on and will not engage into 4 wheel drive on my 2005 rodeo

With ignition key turned on ,but engine not running, press all 3, 4wd buttons at the same time and hold on for 20 secs. This resets the computer. This same application applies if you are locked in 4x4 and it wont release back to 2wd.

I lost my keys for my 2003 rodeo

you will have to get a dealer to cut new keys to code that dealers have access to and then get them to program to car but also erase old keys so vehicle wont start with old keys
or next more expensive option is new keys, ignition barrel and door barrels replaced which are differently same coded key and locks as well as programming and erasing old keys.

Engine will not shut of until i disconnect the battery cable

The most likely cause of this problem can be traced to the key switch itself. I highly recommend you have the key switch either tested or replaced. It sounds as if the circuit is not getting cut when the key is turned off. I hope this helps and please do not forget to rate me.
