Opel Corsa C ( 2000 - 2006 ) Fuel Pump -TEST Before removal and Replacement

[@michaelconrad7839]

Super explained! Thank you very much. I just wanted to see how to remove the ring that holds down the pump in the tank. Your's is the only video i could find! Excellent Job!!

[@TasosMeli]

This is the best tutorial video, it helped me to do the job correctly, I also used the plan B. Thank you very much!

[@jeyloureiro]

Always safe to say that... smoking is not recommended during the process! :) Cheers

Thanks for all of videos dude! You had done amazing work. I'm a your new subscriber. Greetings from Turkey. ❤

[@bobbybob7368]

Thank you very much for a clear and useful video. Now to see if I can get my Opel death-trap to start again..

[@christianolsen6716]

Is it the same on Vaxhall vectra c gts? (Engine: z18xe) i hear my fuel pump the first time i turn on my ignation but not every time and if i wait an hour you hear the fuel pump again, do you think i have to buy a new fuel pump? Or is it something else?

[@David167projects]

My pump seems to not work. I joined no 30 and 87 terminals like you did but the pump still did not work. I unplugged connection at pump and checked the voltage to be 12.2 volt. I then put the relay back in and the voltage at that connection was 3.6 volts. I put in another relay but the voltage was still 3.6 volts. The pump has 12 volt written on it so I wonder if there is a reason why only 3.6 volts gets to the connection?

[@doit_vehicles]

Nice work ! It looks like there is some voltage drop along the wires . First double check the connectors , the fuse ( check the voltage / resistance of the fuse ) So u must find where is the point with the resistance and make that pump get 12 v .

[@David167projects]

@@doit_vehicles After further testing I found that with the new pump, when I turn on the ignition there is 3.6v at the pump and the pressure is 10 psi. When I start the engine the volts at the pump go to 14v and the pressure goes to 55psi. So I think it is normal to have 3.6v when the ign is on but the engine is not running.

[@David167projects]

Do the wires at the pump have a secret clip? No matter how hard I pull, they don't want to come off. Also, I had already bought those plastic hose removing tools. But my hose connectors were different. The new type quick release connectors only take a couple of hours to disconnect but the old type screw clamp takes a couple of minutes.

[@rethabilencheke2338]

Thanks for explanation. When I turn the ignition on, I sometimes hear the petrol pump sound, sometimes I don't hear it. And if this happens when I am driving, the car just stops. And when it happens I have to turn on the ignition multiple times before petrol pump makes the sound. What could be the problem?

[@EverH0p3]

Have you had a look at the OBD codes. Hold brake and accelerator down then turn key to position 2. Check engine light will start blinking out codes. Might be pump failure. They do give out. Mine failed but it was total and instant stop, car just would no longer start, not intermittent. It also sounds like bad/loose electrical connection. Could be in the ignition switch. If you wiggle / play around with the switch while driving you might be able to cause it. Also re seat the relay (purple one) and fuse. If you have a multimeter you can test the pump current draw via the relay connections but be sure NOT to connect to the signal side. ONLY the switch side, pins 87 and 30.

[@rasfordradcliffe6113]

Can you please help. My opel corsa C utility 1.4 gamma. Is over fueling. And high beam lights show active on the dash but nothing on headlights. What do I do

[@johncollins8304]

Extremely good. The pressure regulator is fixed into the lid of the pump assembly isn't it? I didn't know at the time and just ordered the assembly witout lid. The pump is rated at 4 bar/ 60psi but I measure 50psi on the fuel rail (new filter). I've been told t

[@alanblack1333]

to test for volt drop can i just back probe live feed/red wire and attach my black com socket multi meter lead to chassic ground with circuit loaded

[@doit_vehicles]

No , that will read you the battery voltage

[@juviecapones3608]

What is ah good volt drop test when checking that drop test thanks you

[@khaled_ismail]

Back again to the Corsa! I feel lucky 😊😄

[@brandanfiederlein3390]

hi, i have a question. What colours are the positive and negative wires on the fuel pump? Just a bit lost cause there are 4

[@doit_vehicles]

The thickest ones ( black , red ?

[@brandanfiederlein3390]

doit_vehicles alright, thank you for the reply

[@EverH0p3]

Brilliant thanks. I have a weird question. When everything is back together and the pump is running, listening at the tank pump access cover, can you hear fuel rushing?? I am trying to track down the cause of a painful pressure loss issue. I recently replaced the pump. It ran brilliantly for about 20klms then hard to start, poor power and slow to build revs. The NEW pump gets the pressure to 55psi instantly at the injector rail but pressure is lost instantly when power is cut. Its a new pump so I dont think its the check valve in the pump body. The pressure regulator wasn't touched but the metal tank cover its attached to was covered in rust that I cleaned off with rust removing acid. I checked the pressure regulator with air pressure and it seems to be functioning fine. I had the injectors out, still hooked up to the rail, and turned the engine over. They look like they are working fine, all the same spray pattern, no leaking. Im wondering if fuel is getting past the plastic fitting that the regulator is housed in hence hearing the rushing noise. BUT it may be normal... then Im out of ideas....

[@paulkomn946]

firstly needs the suitable pressure gauge to see if the loss of pressure comes from fuel injectors or the gasoline circuit.

[@MrNostram]

2:27 On my Corsa c, on the fuel pump I see 3.5 v and the car doesn't start. any idea why?

[@doit_vehicles]

Check the wires , they might be coroded , pinched

[@mohanpowar9831]

Good

[@David167projects]

Did you find out why your pump only had 3.5 v ? I seem to have the same issue. If I bypass the relay, with the wire as shown in this video, I get the 12 v. But with the relay in place it is only 3.6 v. My pump did not work even with the 12 v but you may have found the answer to why there is only 3.5 v at your pump.

[@--tsatsa--]

Great job man 😃👍

The nylon tools work (just used them on mine) just requires a bit of wriggling to get it to sit right.

[@cosmassanga9581]

Hello Doit, good to see you explaining this in detail, you have helped me out so much, But i have a question, I need your help, I have corsa c 2001 1.4 16v gasoline, I have changed my fuel pump using a MESSMER PUMP 770103A, it has 2 bars pressure on it I think it is for diesel engine ( I have googled it). But it worked just fine on my Corsa 1.4 gasoline engine, so my question is, is there any problem so far with this diesel pump using it on gasoline vehicle? and the 2 bar pressure is it enough for this vehicle to run smooth ?

[@doit_vehicles]

Does it run smoothly? Does it run at all with 2 bars fuel pressure?

[@burakburak1173]

Thanks for video!

[@stevealcock1394]

Hi what's the thread size on the service valve on the fuel rail? I need to buy a fuel pressure tester but want to make sure it has the right union in. Thank you.

[@anthonygrima4]

can the fuel pump be somewhere else instead in the tank

[@doit_vehicles]

No it can not . Why ?

[@huwandavids8407]

iv replaced my pump, fuel rail and regulator..car drove ok for a few weeks then bad pressure agn..wot to do next?

I don't understand how you changed regulator. It's fitted to the cap and I can't find the cap for sale or the entire pump with the cap. And I can't find out how to test it.

Bro thanks for the videos . I have a question you might be able to help me. I have a Opel Tigra ( x14xe ). Recently i replaced the fuel pump and after i start the engine i had pressure on the fuel tanks cap. Every time i started the engine pressurized air was coming out of the fuel tank cap. Is is possible that i have connected the + - wrong ? PLease help .

[@doit_vehicles]

So you have fuel beeing deliver corectly through the right line and air coming out from the fuel tank ? 🤔

[@tigrasedessa]

@@doit_vehicles yes

[@juanguillermo17]

i´ll love to see this done in a diesel corsa

[@RealViPdude]

Is the fuel pump the same for Diesel and Petrol? I cannot find any replacement part for Diesel, they all say gasoline. I have searched everywhere.

[@doit_vehicles]

Diesel engines have high pressure fuel pumps

bro i bought new fuel pump and its bigger than before. the down of the plastic of fuel pump bed is not fitting. is it okay that its not fitted?

[@doit_vehicles]

You mean the small filter ?

[@ALINUED]

@@doit_vehicles no its same as your situation. the new fuel pump is bigger than old one and not fitting into white pump holder. what can i do? i ordered it because everywhere says its compatible with my car but its not fitting...

[@doit_vehicles]

As long as you don't damage the fuel level sensor try to improvise a way to fit in or just attach it on the side . The input port should be always in gasoline .I know it's not the right way , but I guess you wanna save money ..

[@ALINUED]

@@doit_vehicles actually there was 2 type of bosch pump for my opel corsa. i bought the kit one with filter and everything and it was 100euro. other one was 40 euro. so i wanted to make some good improvment but its not fitted. i didnt want to left the pump inside without cap it would be play around. so i will refund it and go with the cheaper one sadly.

[@doit_vehicles]

I see .. btw , there wont be any improvement in just switching to a " better " fuel pump

I have a problem. When I turn the key, there is no sound from the fuel pump. I checked the fuse and it is intact, than I reversed the two relays but nothing starts. I bypassed the relay contact is and ok. I disassembled the pump and tried with the cables and it works. What could it be ?

[@filmeseverin]

Check the fuel pump electrical connector (you can try using a contact cleaner spray).

[@AlexynoCara90]

I have the same problem when I turn the key there is no sound but when you turn the key the fuel is flowing tough toe right hose and is flowing fast. My car doesn't start
