This sounds like a fuel pump relay.Since it cranks,that means everything input to the PCM is good.These are start relay,start solenoid,starter,ignition switch and brake safety switch.The direct output are the fuel pump relay and a relay called an auto shut down relay,which is directly activated by the fuel pump relay to power the coil and injectors.Since the 2 relays are obviously the cheapest,take a reading at both.Some makers do not have a shut down relay but I think those are mainly Chevy.The CCRM,I am not sure what that stands for.As for the battery charger,I would need to know a little more about the situation.If you drained your battery trying to start your car but wouldn't,they are not likely related.As for the fuel pump,I wish you would have researched a little more because I know it is expensive and a pain in the a** to change.Relays go bad more often although 2 years I changed my pump on my 1995 Ford Escort.Wht I'm trying to get t is to try starting with cheaper fixes first,then you won't feel so bad if it doesn't fix. :( Just a suggestion but I have been doing repairs for years and have a system worked out due to experience.Relays are the most common fail items too,as well as switches,bulbs,and many other components but if you notice,most of these items are relatively cheap.If you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.Good luck,Greg

    I have 2001 Cobra Mustang that has no fuel pressure. It had not been started for a few weeks and when I tried to start it, it started to catch and I got off the key too quickly and tried 2 times more and it wouldnt start. I am getting conflicting info on the fuel pump relay location and the 20 A fuse in the power distribution box under hood is good. Inertia switch does not seem to be tripped either. Does the CCRM relay control any of the fuel pump functions or power to it? My next step is pull apart a terminal block connector that seems to leave the inertia switch and go to the tank to see if there is power there. Car has only 15K on it, shouldnt be the pump, right?

    Ive got a 96 mustang GT 4.6 L it was parked for 2 months not driven at all then I go to get in it and start it up it started but ran real ruff ive replaced the fuelpump ,fuelfilter ,blew out the fuel lines ,checked the coils,fuelinjectors, noid tested the injector wires,new camsensor ,replaced the plugs and wires,car will idle but when I give it gas it dies out I have fuel in the rail but its acking like its starving for fuel Im really stumped this is the first 4.6 Ive worked on Ive got 3 other mustangs but they are the real deal V8s lol 5.0 and 5.8 if you can please give me some input I need help . miller78

    That sounds like a throttle position sensor miller.When it is bad,it has no idea how much gas is required,nor how much gas is being delivered.It also could be simply the gas has started to junk out.Ethanol will cause that on a car which has sat around for a couple of months.The cheaper way to check it would be to add some octane boost for now,preferably with a half empty tank or less and then add some gas to mix it up better/dilute it.Then if that doesn't help,best bet would be the TPS.

After checking the fuse in the under the hood fuse box,if its ok next I want you to look in the trunk on the left side ,your looking for a black plastic switch with a red button in the center of it, check to see if the red button is pushed down, this switch is called the Inertia switch which upon impact is designed to break the voltage flow to the fuel pump, if that is depressed and the fuse is good next you need to obtain a 12 volt test light, you should have two wires going into the inertia switch one dark green with a yellow tracer,and another that brown with a pink tracer ,find a good ground point to hook up your test light clamp to (in the trunk, near your inertia switch,make sure you have a good ground or you will get falase results causing you to replace parts that you don't need) next you need to back probe the switch at the dark green and yellow wire , this next step require's a asstance to turn the ignition switch from off to the run postion,at this point (from when the key is turned from off to run ) you should see your test light glow for 10 seconds then go out,this is normal, if you in fact find that your light does glow then we know that your fuse is ok, your engine control module is good and your new ccrm is working correctly ,next in want you to back probe the brown and pink wire at the inertia switch and have your assistance re cycle the key from off to the run postion (this will test the inertia switch) again your test light should glow for 10 second ,this brown and pink wire is the wire going down to the fuel pump.if you find you have a glowing light on the green with yellow but not on the brown and pink you have a bad inertia switch. hope this helps ,if you still don't fine the problem ,write back and give me the results of your test and we will continue from there, remember thur incomplete test will only lead to replacing un nessary parts

No engine start, engine has fuel pressure, spark and crank but injectors do not open and inject fuel.


Check the injectors, do they have 12 volts to one side of the plug with the ignition on, if not check the ECM fuse under the hood. If the fuse is blown then you may have shorted engine wiring harness or other issue with the wiring.

I have a civic 04 ex automatic the key don't come don't have spark and the injector not pulsing does the inmovilizer have something to do with this problem ?


just went through similar issue with a 99 accord spark would be out because of the crank sensor but wouldn't kill injector pulse there is what is called a main relay honda used it controls both the injectors and fuel pump my car wasn't getting fuel pump power if you pull relay down should be next to brake pedal under dash and 7 wires and pull internals out and check circuit board for burnt solder or cracked solder when i wouldn't hear fuel pump i would take and apply light pressure to circuit board then fuel pump would kick in the injector side should be 6 volts and fuel pump should be 12 volts i would change crank sensor and get spark to return and then trouble shoot injectors also my car had after market remote start and keyless entry and was causing the key not to be recognized i removed alarm and got the coded key to read then had to trouble shoot the other problems after rectifying others first

05 c240 turns over won't start


most likely you have a bad crank sensor or fuel problem you need to check fuel pressure ,if you have enough pressure ,most likely you need crank position sensor,if you don`t have fuel pressure ,it might be your fuel pump relay or the pump, i would start with the relay first very unexpensive. you can also hear the pump if it`s working by cranking the engine and listening rear of the car for a humming sound .
good luck

96 Lumina 3.1 won't start. It runs when I spray starting fluid in the throttle body. It has 42psi fuel pressure at the fuel rail. Is it bad injectors?


It is not bad injectors, it is lack of injector electrical pulse, never would all the injectors fail at once. See if you have 12 volts (use a 12 volt probing test light, avail at any auto parts store for less than $5) to one wire of the two wire connector of each injector with the ignition key in run position. If the test shows no hot wire at the injector connectors then check fuses marked ECM1 and ECM2 in the under-hood fuse block. If they are popped then you have a shorted harness or component.

My 96 dodge neon randomly died on my while i was going down a 55 mph road. I replaced the fuel pump on it because i was told that was what was wrong with it. I located the fuel pressure gauge under the...


What you've found is the fuel pressure test port, not a gauge. It is the point to which you would attach a gauge to determine cranking fuel pump pressure.

About all I can say at this point is that you probably don't have enough fuel pressure, since it "dripped" out. Proper pressurization would have caused a brief burst or spray until the pressure fell off.

Have you tried a fuel filter?

that has a votec engine in it the fuel pressure is droping at knight and it takes 60 psi before the injectors will fire most likely cause fuel pump ,leaking injector ,or a feul pressure regulator

Fuel pump relay


GM relays don't reset. My guess would be the electric fuel is not operating, For openers , I would start with the FUSE for the fuel pump. In a fuse panel UNDER THE HOOD. Should be marked. Probably a 30-40A maxi fuse. CHECK WITH A 12 VOLT TEST LIGHT. If that area passes all the tests, I would check for power to the fuel pump ( with the ign key on. 12 volt test light will go ON then OFF ) Could be a faulty fuel pump, Hope this helps

Fuel not working


should have 12 volts at pump during engine cranking. with key in "on" position, the fuel pump only gets voltage for 2 seconds if engine is not running. Read voltage during cranking. Check fuel pump relay in battery jucntion box under hood.

1985 Ford F-150 Truck (EFI) Fuel Problems


Same problem with my 85 F-150 5.0 EFI---turned out that the fuel pump relay under the hood was teriffically corroded on the inside (I opened up the relay to look inside). When I checked the voltage at the fuel pump it would show 3.5-6 volts instead of 12 volts.

I was thinking fuel blockage or perhaps failure of the in-tank pumps. Sometimes the truck would start and run, othertimes it would neither start nor run. Typically, if running it would stay running until turned off (where the relay had to break).

Changing the green fuel pump relay fixed the problem--12 volts now at the pump and no reoccurance.

Good luck--let me know if this fixed your F-150.
