As for the fuel sensor light blinking every time you turn a corner or climb a hill -
this sounds indicative of a fault on the sensor float assembly: Mounting out of whack, sensor not working, or loose electrical connection. A trained mechanic will check electrical connections first and if are OK then replace the sensor assembly in the gas tank.
I have 2001 Rodeo, and have had this truck since 2003. Great vehicle if you properly maintain it. I also had the fuel light issue and the check engine light would come on while driving up and down roads with slopes. It started just like yours 4 years ago, I kind of ignored it, but it got to the the point that it stopped working all together. Your issue may be your Fuel sensor gage, which does not impact the operation of the vehicle but you could run out of gas if you don't know where your level is at. I took the vehicle to a dealerships for diagnostics test was giving a ridiculous price to replace the fuel sensor. I then took it to my own mechanic who fixed it for less that $400, which is mainly the cost of the part which was $280 + labour.
Engine light stays on and loud idle noise same as at home before trip. Had mechanic look at it on trip. He said he saw no
problems. Said I need to install padding under hood. Its white with front guard and rear tire.
Great vehicle.
A different mechanic said it was the fuel guage. I replaced the entire cluster...problem still persists.
Summary:
Guage read empty.....Replaced, fuel pump, replaced fuel pump sending unit(twice), replaced vehicles computer, replaced entire guage cluster.
The guage still reads empty..never wavers..like it is NOT geting any power.
This is driving me crazy, and I have to drive from Orlando to Colorado Springs next month.
Please..any ideas at all . Thanks
The light will come on at start-up for about 3 days and then not come on when I drive the next time. It never comes on or goes off while vehicle is in motion.
Any ideas?
My friend is a mechanic and has re-wired some of the harness and we thought he'd fixed it but now the light has come back on. I even have a friend who has the same car and he has problems with his too! I actually hate the car.
We're going to host a destruction derby with our isuzus and people can pay a small fee to watch. At least I'll get something back from it.
Also, the vent line clogging up cn cause an intermittent light.
I just had mine blown out, and it solved my inermittent light problem.
He says probably something is wrong with that one cylinder it might involve a full overhaul of the engine.
Can somebody provide some expert advice on what the next steps should be for me?. Looking for second opinion.
Thanks...
This is the craziest thing, but I have a 1996 Isuzu that the "check engine" light just came on in. And as it turns out, I just drove from Orlando to Colorado Springs in April. The coincidence was pretty weird. Hope your drive goes smoothly!
Apparently there are many items in the emission system that can cause the light and the same code.
