Geo :: 1995 Won't Start - Cannot Hear Fuel Pump Whirring
Mar 18, 2012
Geo won't start. It has a new battery and air filter. Just replaced the fuel pump and fuel filter. I don't hear the fuel pump "whirring" when I put the key in the ignition (to on position). All the dashboard lights come on when the car is in on position.
I suspect the relay or the fuse, but having trouble finding the correct one of each. What does the relay look like? i.e. part number? What is the spec for the fuse? 20amp 30 amp? This has been a great car.

I'm working on one of our fleet vehicles here, a 1995 Explorer. about 2 months back, it stalled out. Got it back to the shop and turned the key on .... I couldn't hear the fuel pump. I replaced the fuel pump and the fuel pump relay. Vehicle started right up and seemed to run O.K. About 2 weeks ago, it stalled out again, same symptoms, acts like it runs out of gas and can't hear fuel pump.So, I have been playing with it and find that it starts up great in the cool mornings. In the afternoon when the temps are hotter, it won't start (can't hear fuel pump). The following morning when temps are cool, it will start right up and can hear the fuel pump. I almost wrote this one off as a defective fuel pump, but I'm not sure on this one.

Got done with replacing head gaskets and intake gaskets, Van started fine and I backed it out of the garage. Left it running and put down ramps and drove up on them so I could get under and connect the exhaust. Got that done and then got back in it and all it will do is crank and it will not start now. It also has a new cam shaft sensor( wire broke on old one). I can hear the fuel pump when I turn the key. It is like now there is no fire to start it. What could be wrong? What do I check? What causes it to fire? If something was connected wrong, would it have still started and then wont do anything but crank? Got dark on me and started raining so I say tomorrow is another day. I feel it is something simple.

when I turn key I should hear fuel pump, I don't. I can jump pump & it will run but it still won't start. I reset inertia switch, switched pumps (new one) still won't start. What next????

2005 1.8t gti wont start. The other day I was driving on the highway when a thin plastic type wrapping got caught in my serpentine belt. The car immediately died and I hit the gas and nothing and with no power steering i pulled over to the side.
Timing belt was done with water pump and tensioners
Spark plugs and coils are brand new
What fuel line to disconnect to test if the fuel pump works? Like I said in the title I cant hear the fuel pump priming. The engine was running 100% before this 2 techs saw it and the vw dealer i workrd at looked it over.

I have a 2011 Sonata GLS with ~65k miles. I have an intermittent problem with the cranking, but will not start. It sounds like the fuel pump is "whirring" before start, and this only happens once a week or so. Other times, the car starts fine. The gas tank is ~1/4 full also.
There has been another intermittent issue (not sure if it's related) - with the O2 sensor heating coil. The check engine light comes on for a day or two and goes away wit the O2 heater coil problem. However, I'm not sure a sensor coil problem would cause the car to not start when it's cranking.
Could it be the crank sensor issue? Is that issue known to be sporadic?

So last week something happened that I've never had happen before. I was dropping my daughter off at school and I noticed that my dash lights weren't on. My headlights still worked and the blinkers did to.
When I got home and parked it, I checked out all the fuses. There was a 20 amp fuse that was blown, so I replaced it and then checked the relays under the hood. I turned on the key to check the dash lights and they still didn't work. The 20 amp fuse blew again, so I replaced it again. Now the dash lights work again.
However, when I tried to start it, it would turn over, but the fuel pump isn't turning on.
Long story short, I've replaced all 4 relays under the hood, installed a new fuel pump and also replaced some bulbs in my taillights and sides over the front tires. It turns over when I try to start it, but the fuel pump still isn't "kicking" on and it won't start. I feel like somehow, power isn't getting to the fuel pump.

My 1995 ford ranger with a 3.0 will not start. It acted like the fuel pump was going out so I replaced it. I also replaced cmp sensor and the camshaft synchronizer due to old cmp sensor broke and messed up the synchronizer. My truck is getting fuel and spark but still will not start. Where do i go next?

I've followed steps 2-6 from this image
I don't feel any pressure in the hose from the fuel filter. I can hear a buzz (guessing its from the fuel pump) but no pressure.
I've checked both fuses, the efi main relay, and swapped out the circuit opening relay with a known good one and all checked out good. Only thing left is the fuel pump or the writing and electrical connectors.
Car has pretty much took a dump one morning and has almost no power. I can't find anything else wrong with this car besides this. Is the fuel pump the problem even though I can hear the pump?

It was acting rough and was a little loud. Like a low deep loud, the engine light came on. I tried to start it, it would crank but no start.
Code came up P0340 (Cam sensor) So i replaced it, reseted and scanned again, now it says P0343 To much input sensor 1 bank 1. When i turn the key over to "ON" I don't hear the fuel pump, is this normal?
I don't understand what to do I am so lost, I am ready to do the timing. Is there something cutting my fuel pump out or is it done? Do i do the timing, or replace the pump ...

1995 Ford Explorer, 4 ltr. engine, pushrod. Will not start. Replaced fuel pump, fuel filter, every relay, pressure regulator, and the crank position sensor. I realize there's a whole bunch more parts under the hood, but I am ready to give up. Before the fuel pump would not run. Reason for replacing the parts. Now it won't stop running and you can feel the fuel by-passing at the pressure regulator. When checking the pressure at the rail I get zero !! I used a tire pressure tester for this. And, like I said no pressure. This vehicle has around 170,000 miles on it.

I have a 96 buick regal thats been giving me problems for over a year now. it from time to time acted like it was out of gas even though it might have a half a tank. Turns over fine but won't start after it sits for a couple of days then it starts fine. Last summer my son replaced the fuel pump after doing a pressure test and getting a low reading. No more problems until jan then it started doing it again. Well about 3 months ago it wouldn't start so I had my wife turn the key on and I stuck my ear in the fuel fill tube and I could not hear the fuel pump.
I checked the fuel pump relay by putting my finger on top of it and I can feel it click when the key is turned on. Also the air relay next to it is the same so I switched them no change so I replaced the fuel pump again and also the sending unit so every thing in the tank is new. Car still won't start can't hear the pump running and i checked for spark no spark now. My other son has been saying he thinks its the ecm so I just put a reflashed used ecm in. Did the security relearn procedure still nothing. whats next? Somebody told me check the cam and crank sensors and wiring. I also replaced all the ignition coils last summer.

After my 95 GCL wouldn't start and was towed to Jeep dealership, the problem was diagnosed has the fuel pump. I went to pick up my Jeep. Started and ran beautifully..but I noticed the air bag light was on, and wasn't that way before it wouldn't start. Went back into dealership and told'em..they told me nothing they did would have any bearing on the air bag or the dash warning light. What could have happened to cause this problem? I have re-booted the electrical system (more than once) by disconnecting the battery.

I have a '95 Chevy Caprice Classic 4.3L Sedan, and it cranks but does not start.This started happening after about a year of the car just sitting in the driveway. Before she sat for that year, she ran just fine.
I am under the impression that the problem is the fuel pump, it is NOT running when the ignition key is turned to the "on" position,this is very confusing because a volt meter placed on the connectors going directly into the pump motor shows 12+ Volts when the key is turned, for about 2 seconds, as it should, however the pump motor does not run. Also, I have already replaced the pump relay AND the entire pump assembly (though the pump I used as a replacement was also pulled from a junkyard vehicle).
The MOST confusing part is, when either of the fuel pump motors that I have are plugged directly into the car battery, they run just fine.

My issue. 95 short Aerostar, Vulcan engine, A4LD trans. Just got it last week. Bought a new trans and when I went to pull the van into the shop, it wouldn't start. Cranks but won't run. First thing I checked is fuel pressure, got zero. Pulled the kick panel and found the inertia switch, but the harness for the switch is getting 1.8 volts with the key in "ON" and the same with it in "START". IIRC it should be zero in RUN after a second or two (if the engine isn't actually running, that is), and 14 in START.
Checked all fuses in the panel by the steering column, they're good, and switched around the 3 relays by the battery. No good and I don't hear the FP relay when I turn the key. For now I'll run wires directly from the battery to the pump, just til I get the trans done, but it needs to be fixed anyway because I plan to make this van a DD. Here are my questions:
-Is there a second fuse panel I didn't find?
-Could this be a computer issue? If it is, would the computer fuse be blown?

My 95 chevy 1500 pickup is having fuel pump issues. Somewhere between the relay and the sending unit. Pulled the tank, and put power directly to both the pump and the sending unit. They both run. Put in new relay, still not turning on the pump. Do not know if this is related, but the switch to turn on the interior light when you open the door does not work on the drivers side door. If I pull on the switch the light will come on.

My '90 240 will not start. When I turn the key to Acc. or Start I hear a whirring sound coming from the fuel pressure regulator so I assume the fuel pump is not an issue. The engine will not even crank. I assume it is the ignition coil or the starter but I am unsure. As an FYI, the battery and plugs are good.

01 7.3. Cranks, won't start. Tank was at 1/4 but is full now. The lift pump runs, I can feel and hear that the motor is spinning when I cycle the key. I removed the fuel filter and cycled the key and get no fuel into the bowl. It looks like the lines are stainless from the pump to the tank so I doubt it is sucking air. I pressurized the tank with a shop vac and I get fuel coming into the filter housing. Am I missing something obvious? I have never seen an electric pump that would run and not pump fuel. I removed the suction line at the pump and don't feel any suction there.

I have a 95 Ranger 2.3 with a manual tranny. In the past I have had problems with this truck not starting do to a bad inertia switch and numerous fuel pumps. A couple of weeks ago I pulled the truck off of the driveway into the street and let it set there for a few hours. When I went to put it back on the driveway it would not start. I got it pushed on the side of the garage. I did my normal routine of doing a pressure check. I had no fuel pressure so I assumed that it was the fuel pump (as usual) so I dropped the tank and changed the pump.
I got it back together and it still wouldn't start. I checked the fuel pressure and the manifold still had 0. So I started my diagnostic. I have power from the fuse to the fuel pump relay. I then checked the wiring at the inertia switch and found that there is no voltage with the key on at the supply side of the inertia wiring. I verified continuity between power distribution block and the inertia switch. I put in a new fuel pump relay and it still has no fuel rail pressure and there still is no electric signal at the inertia switch. Where to go from here?

I ran out of gas one day refilled the tank and car still won't start. Took it to an mechanic he got it running ( saying it was the fuse and electrical problem) got it home and the next day it die on me again, so I called him up and he say it the fuel pump, so I got it replaced and it still won't start. So what's the next step on getting my car to start again.
