Replaced fuel pump and checked all fuses as well as replacing the battery after rodeo had sat for time. when we tried to start it ran for a few seconds then popped ecm back up fuse. replaced fuse started and samething again. now by just replacing fuse and turning ignition to on but not starting it blows fuse. any help please and thanks

How can a new fuel pump not work? Did you check to make sure that it is running? Getting power? If powered and not running, it is a DOA and replace it.

What's the engine compresion ? sitting that long can cause engine ring problem , Did you clean the injectors or replace . fuel gummed up ! Clean fuel lines . Or when you parked it did you run it till fuel ran out , pulled fuel pump fuse ? Squirt some oil into the cylinders an turn it over a few times . These are a few thing's that should be done before leaving a vehicle to sit. Flush out fuel lines too

my problem was electrical, removing the batt (neg. terminal) for a few seconds resets the Engine Control Module (ECM) which operates the full pump relay, there should be a fuse in the relay box in under the hood labeled ECM or ECU. Pulling that fuse for 10 secs. or so also resets the ECM, try this and if it immediately works I suggest to drive it locally until it will not start again and repeat the removal of the ECM fuse. If this work out I suggest that you ECM is receiving a sensor signal to shut down the pump relay so I've been told, is the check engine lite on

I would try seafoam added to fuel Injector system maybe clogging up.of course ignition spark needs to be verified if it is actually working.

Is the Check Engine Light on? If so, can you get a code reader to read the codes and report back what they are?

When you get in the car and turn the key just to the "On" position, do you hear the fuel pump wining for a few moments?

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.

It sounds like a fuel pump getting weak and hot. First check the ground wire at the fuel pump pigtail. and replace the fuel fiter.

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!

If you can hear the pump run and you get no fuel its the pump, If it blew the fuse i would say the pump tied up. That happens when you run around on empty a lot, gas is what keeps pumps cool when you run under 1/8 of a tank pump is not submerged in gas to keep cool hense pump burns up.

disconnect your glow plug relay and try it, the relay may be shorted out
