Do an ohms test on wiring loom if any higher than approx 5ohms when everything is disconnected bad connection. this can still show good voltage but pump not getting enogh amps(current) so it burns out windings in pump
are old pumps open circuit?
test with ohms meter
if so check that wiring and connector pin tensions

Check your Ground wires or cut them and make a solid ground to the frame. Your fuel pump probably has a faulty ground but not on the power plug on the ground plug or the other end of it where its going to or maybe its severed somewhere.

1988 Isuzu Trooper II LS 4dr/4wd I changed fuel pump and inline filter about month ago, it will run but only if i keep it runinning with gas peddle at high rpms, will not idle as soon as I stop with...


Hi,
That looks like air in the fuel system. Bleed the fuel system by loosening the bleeder nipple, pump the bleeder( top of the fuel filter cartridge ) remove any bubbles that comes out from the bleeder, if there are no more bubbles tighten the bleeder and start the engine.

Hope that helps you out!

Dealer wants $1000 to replace isuzu trooper LS FUEL PUMP something about having to reset the computer and special tools to replace pump is this a fair price or!?? Thanks


well i just called auto-zone and they only want $105.00 for the fuel pump on that 2002 trooper Ls. So i would have to say that's way to much money!!!! that's $900.00 labor..( for a 3 hr job.) that job i would do for $450.00-$500.00 total. And a dealer has all those tools already, its not like there going to go out and buy the tool to do your SUV so that should have never even been brought up....and resetting the computer is nothing, i would run as far and as fast from that place as possible. find a local mechanic shop (not dealer) to do the work. and tell them you already priced the fuel pump from auto-zone $105.00 ( and you will get an honest quote for labor.)

Lost power to engine


Check make sure all plugs are firing. Sounds like what my 93 Rodeo was doing-Idled okay but very rough when in gear. Turns out only 5 out of 6 plugs were firing due to a defective ignition module- 100 bucks later it works fine.

Hope this helps.

yes, i had the same problem. i've got a 93 isuzu trooper, but look in the chilton's manual, the engine and fuel systems are all for the most part identicle. My fuel pump went out, so I had to put it on a lift and drop the fuel tank. the pump is actually Inside the fuel tank. swapped it out along with the strainer, and now it runs like a dream. hope that helps.
