If you can run a voltage test to make sure everything is working you'll find that it has a very low voltage simply because your unit is submerged in fuel. But this will tell you that your ECU is receiving some kind of signal; however, what is being outputted is different so you need to take your rodeo to a Isuzu dealer and even tho a passport is the same car Honda dealers can't do it.
An Isuzu dealer can be hard to find at times because some dealers will sell Isuzu but not be certified Isuzu dealers, I know that sounds wierd. Anyways If you've replaced it and checked the wiring and know everything is ok then there are 3 codes that need to be programed into your ECU to fix your fuel sending unit and this can only be done at a dealer
My Trooper did the same thing and I replaced the fluid and filter and added a separate trans fluid cooler and that fixed the problem.
The srs light indicates a problem with the airbag system.

The oil light could be blinking in an Isuzu Rodeo because it is time to get the oil changed. This could also occur if the oil is low.
I had that problem and the hazard light switch was bad so when it was replaced the horn worked just fine.
bat motor mounts cause the shaking a knock sensor realizing its shaking is the light get new mounts
it could mean that you have a loose battery cable that needs to be tightened
Have you checked the daytime running light module?
No problem
Most likely turn signal flasher needs to be replaced
Probably the fuel pressure sensor malfunctioning...
It could be that the circuit board on the back of youre cluster is damaged and needs to be replaced. The light bulbs are also linked like a set of X-mas lights, if one is burned out the others could not work.
