You'll need to take it to a shop for a diagnosis before you waste any more money.
One possible cause is the fuel injectors or the fuel pressure regulator.

Installed fuel pump on a 97 rodeo and its not pickin up gas (not firing) what should i try

Hopefully you checked the relay switch under the hood before you replaced fuel pump. If not you can get the switch from o'reillys out parts for $22. I replaced it first b/c mine acted like it wasn't working at all and that fixed my problem.

We need to determine if the issue is spark or fuel. Fuel pump failures occur to cause what you describe, without any indication of what has failed. I have had success in determining if it's fuel pump be removing the fuel pressure regulator, covering with a gag, and having someone turn the key on momentarily while I watch for fuel to pump out of the fuel regulator location. Be careful though, this is raw gasloline and flammable.

Fuel pump in my 97 rodeo works if i wire it to the battery,but does not work when i plug it in where it belongs.I've checked the fuses and they all look fine.

Same thing happened to me on my 1996 isuzu rodeo. My fuel pump worked part of the time. I actually bought a new one, then tested the old one when I removed it. Like you, I hard-wired it to the battery. It turned out to still be good.

It turned out to be a bad ground connection from the fuel pump. You can check it by --- 1) hooking the fuel pump back up where it belongs, 2) splicing a wire from the ground wire coming from the fuel pump and 3) grounding the wire (loosen a bolt head on the undercarriage, stick the stripped wire tip between a bolthead and undercarriage surface, then rachet the bolt head back tight. Then 4) just turn the ingnition key and see if the fuel pump engages and the engine starts.

Good luck!

Adjusting fuel pump

If you have the 91 3.1 V6 Rodeo you can't adjust the fuel pump or fuel pressure. The only thing you can really do is to get a throttle body rebuild kit that will have a new diaphragm for the fuel pressure regulator. If you want to adjust it, you'll have to get an aftermarket regulator and install on the return line (the smaller line) and remove the spring out of the regulator on the throttle body. If you feel the fuel pressure is too low, then you might need to change the pump. Its located in the fuel tank, only takes 1 or 2 hours to do.

99 Rodeo 3.2 V6 fuel injected .

sounds like u may need a new fuel pump, the problem is the system doesn't hold fuel pressure after shut down, the check valve that does this is part of the fuel pump in the gas tank.

My rodeo always has a little tap in the engine. But your stalling / no power issues sounds like it could be a clogged fuel filter or fuel pump going out.
