I have a 2004 RA model rodeo 3.5 V6 petrol 4x4 ute. It wont start. I have no power to fuel pump fuse, starter and O2 sensor fuses. I am leaning toward malfunctioning Immoboliser or transponder key or both. My MIL/check engine light does not light up when i try and start the engine any ideas?

do not reuse head bolts or apply any lubricant to the bolts. Do up bolts in following order for each head.

"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...

I had the same problem, I changed everything, air flow meter, plugs, leads, checked the timming belt etc. etc. The problem turned out to be the fuel pump, its inside the tank, you need to check the fuel pressure with an inline guage, it needs to have 30 psi, mine was only 15 psi. also you should have the injectors cleaned. good luck.

First things first...Rewiring the fuel pump will only put a "Bandaid" on whatever the problem really is and will most likely create a situation where wires are draped across places where they shouldn't be, causing all kinds of future electrical problems. I have had to clean up that type of mess too many times.That type of "shade-tree" repair makes proper diagnosis and repair of a vehicle nearly impossible, even by a trained technician. My recommendation: DON'T EVEN THINK ABOUT IT!

OK, Now that I have my preaching out of the way...
The check engine light is supposed to come on every time you turn the key to the "On" or "Run" position before starting the engine. This is for a "bulb-check" just to let you know that it is not burned out. It should go out immediately after the engine starts and should stay off the entire time you are driving the car. It is not any type of indicator to let you know that the fuel pump has run. If your check engine light is not coming on every time you turn the key to "On", then there is probably a problem with your ignition switch or your ECM Main Relay. Either of these can cause an intermittent failure of the ECM to power up, a)d thus, not turn the check engine light on. Failure of the ECM to power up will also cause the fuel pump to not run because like the check engine light, the fuel pump is controlled by the ECM. (Rewiring the fuel pump will not make the engine start if this is in fact what the problem is.)

I have also seen many fuel pumps that run when they want to. You could have a bad fuel pump, but refering to your statement about the check engine light, I would guess that the fuel pump is not the main problem or even if it is a problem at all.
