    I've checked the relay and even switched it out with another, still no pump action.I just bought my rodeo about 3 weeks ago and only drove it once when it started dying out when I made left turns and backed up.It would also chug a little when driving forward.

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!

Have you checked the actual Fuel pump relay? Should be a relay for the fuel pump under the hood, sometimes you can switch the relay with another relay of the same in the relay box and see if that works. Hope this helps

Changed fuel pump not pumping fuel not working correctly relay good getting power second fuse for fuel pump not working one wire fuel pump in back getting weal power 97 Saturn sl2

If I understand your post correctly you have a fuse for the fuel pump that is blown or blowing. Until you resolve that issue the fuel pump probably will not get enough power to run. If it blows when you replace it the you have a wiring problem to your fuel pump. Most replacement gm fuel pumps come with a replacement plug for the fuel pump. Make sure you use it if yours did as there have been lots of problems with the wiring plug being damaged due to the high current draw of the fuel pump.

The oil pressure sending unit could be bad. If your oil pressure gets below 7psi than it shuts off all power going to the fuel pump. It is screwed into the engine block just to the right of the distributor.

The ECM BAT fuse powers the fuel pump through the relay. If the gray wire has power and the black wire has ground, and the fuel pump does not operate, its bad.

Went through and checked my fuel pump,rail,coilpack and all fuses and everything is in working order but still fires and wont start. what should I look for next?

What is the fuel pressure. It could be weak. Spray brake cleaner in the throttle body. If it starts and stays running as you continie to spray then you have a fuel pump issue. If it still starts and dies the same then the ignition module or the crank sensor failed.

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.
