My 1997 Izuzu Rodeo wont run, it will start occasionally but wont run. I removed the fuel pump and tested it and it seems to work fine. I checked the fuse and interchanged the relay from the fuel pump and starter but it still doesn't get any fuel. Testing the leads on the fuel pump itself with my ohm meter I get no reading at the fuel pump. How can I test to see if there is a short circuit somewhere in the wiring from the relay to the pump, or is there something else I am missing?
Why don't u give my solution a try, what will it cost u?? $5, have been doing this type of work 35 years now, so don't suggest things that are a waste of time. ... 1997 Isuzu Rodeo
Where is the fuel pump test connection on a 2002 Chevrolet Astro? Chevrolet use to tape a green test connector sticking out of the wire harness that when 12 volts is applied would power up the fuel pump for testing. Last night it wouldn't start, nor this morning, then late morning I went to listen for fuel pump operation when key is put to the run position, heard the pump and then was able to start the van. I moved the vehicle, and around noon the van wouldn't start again. I could not hear
I had the same problem until I changed the wire harness to the pump. Also the relay under the hood shorts out often and needs to be replaced. Since I did those two things no problems for over a year. ... 2002 Chevrolet Astro
94 Sundance I recently tried to start my 94 Sundance Duster and it would not start because there is no fuel being pumped from the fuelpump. It is the 5 speed manual 3.0L V6 model. I did end up testing the fuel relay and it did work. Then I tried testing the Fuel pump with direct current from the battery And it blew the fuel in the tank about 3 feet so i know that the pump still does work. But when i turn the key it wont pump the fuel. Please help, any ideas?
You know the relay works, you checked it, make sure you have power going to the relay and power at the pump ... 1994 Plymouth Sundance

So back to my real problem of the car not starting. My 1994 Ford Escort wagon has a crank but no start issue now that gives a sputter as if it isnt getting fuel. I have replaced the fuel pump and filter, and have also had the ignition module tested which tested good. I also took off the line at the pump and then at the rail and blew from the pump end and had no restriction in the line. I have no pressure gauge to test the actual pressure but i do get fuel at the schrader valve. I recently change

Sholly, we chatted yesterday about my 98 dodge grand caravan. 1. we dropped the tank to check the fuel pump. we tested the juice to the fuel pump. there is no juice. is there a auto shut off/reset button to the fuel pump? 2. the chilton book is very vague. is there a way to test the relays? 3. also how do you remove the relays to test them? my husband thought they pulled straight out, but they don't. is there a trick to pulling them out ? 3. we read the book, and from what we gather

There is no fire going to the in-tank fuel pump. The Isuzu was left sitting over nite and the next when the driver went to go somewhere, the vehicle would crank but not start, after some testing, we determined that the trouble was the in tank fuel pump. So we dropped the tank and replaced the pump. the pump works fine from previous testing .But there is no current getting to it. Both the Fuel-pump Relay and the Fuse are good. I believe the trouble is in the ECM but, a local garage mechanic disag

There should be a fuelpump relay in the powerbox. The points inside are probably burnt or corroded. Try Autozone or Oreillys for the relay. They may have a diagram or a book for your model car. If not look underthe powerboxes for a matching relay ... Ford Taurus
Ive got a 2001 vw jetta 2.0 that died while driving and will not start. The starter engages but engine is not firing at all. Ive tested the starter which is good. I removed a spark plug & while still connected to plug wire & turned the key to verify spark which it has. I then pulled fuel pump relay & tested with twelve volts & it is operational. I then removed the fuel pump & tested it with 12 volts & it too was operational. I disconnected the fuel line just before the pressure regulator & fuel

Fuel pump is not working and I would like to know if it is the relay or the pump. Is there a test wire to test the fuel pump by the brake master cylinder. I have three relays in the glove box which one is for the fuel pump. This is for a 1996 GMC jimmy.

Fuel issue I've got a 2000 Mazda 626 4 cyl, the will not run. It's not getting fuel. I tested the relays and that's not the problem. The fuel pump doesn't come on. I got it to start with starter fluid but it quickly dies. I have a feeling the pump is shot and will need to be replaced. How do I test to see if the pump is the actual problem. I'd really hate to do all the work to replace it and have it not be the problem. Also, where is the fuel filter located? Thanks in advance!

Fuel rail pressure drops from normal at 3500 rpm to zero at 4500 rpm. already replaced fuel filter, checked rail pressure regulator, replaced in-take pump, external pump replaced by previous owner and tested by me. the external pump makes a whining noise in the vehicle, but is silent during bench test. what is the box above the fuel tank flange passenger side, just forward of the right rear tire, the external pump takes its suction from this box. is the box related to the noise and/or pressure

Refueled on Monday afternoon (a full tank) and on Wednesday morning had trouble merging onto the highway. Couldn't accelerate past 30mph. Car would buck and ping and would not go faster than 30. Drove completely fine under 30 mph. Dealership replaced fuel pump and EGR valve. Did not correct problem. Dealership suspects bad gas and I believe they dismantled gas tank to clean, and flush and test gas. At this point they suspect multi-system failure. ????? Help! Any ideas? Car only has 24,0
