BMW E36 FUEL PUMP TEST & TROUBLESHOOT PART 1

[@Tommynnnnn]

Wonderful video, most professors in college need to take teaching instructions from you

[@TheJ631]

wow that is the cleanest m50 ive ever seen!

[@rockers2rockers616]

That is a super clean engine bay. Very informative. Would love to see one showing how to get to the idle control valve. Thanks

[@cr10001]

Thanks!! I have an E36 318iS which is coughing and spluttering - I suspect water in the fuel but this video has given me some excellent info on how to access the fuel system and some ideas on how to check it.

[@cya3651]

Very helpful. I am currently having a crank, but no start on my 98 E36 M3. Planning on switching the fuel relay and main relay test next . I have replaced brand new (VDO) crank position sensor, but Engine continues to throw code P0335, which says ECU is not getting signal from crank position sensor. I suspect no ground signal from ECU to fuel relay as you pointed out. Any suggestions on what to check why ECU not getting signal from CPS?

[@NickDent]

Damn I swapped those relays like you said and wires started burning and smoked blew out my air vents! No good!

[@trentpope6239]

Same thing just happened to me! Did you have to replace your harness?

[@NickDent]

@@trentpope6239 luckily it was just one brown wire I was able to cut out the burnt section. The harness pack right above the blower motor under the hood

[@NickDent]

@@trentpope6239 We should sue the owner of this video hahaha

[@trentpope6239]

@@NickDent hahahah same wire for me but mine’s pretty cooked. I’ll probably have to wire the whole thing. Were you having fuel issues too?

[@onesikm3]

Y’all are terrible at following instructions lmao 🤦🏻‍♂️

[@trungtube]

Awesome video especially the part (~ @18:00) where you explained and mark the pin out of the relay connector. Helped me diagnose and pinpoint the fuel pump problem within minutes. Thank you!!

[@theuniqueldy]

TYVM this might have helped me find the problem with fuel leaking (top & bottom) from my new fuel pump as well as below new fuel filter. I will have to look to check new one to see if the feed line has ridges or not before I install the new fuel pressure regulator. I am so lost I so miss my 318i & am sick of the bus.

[@dasein9980]

It would help if you mentioned what size diameter hose you use and necessary P.S.I. if you didn't mention it.

[@justasmarkevicius2568]

I think this will be helpful i have the same car and there is no power to the fuel pump, have a question can you actually start and run a car when fuel pump relay is connected with that bridge as shown in the video ?

[@mybimmerspace]

Thanks, I am doing more. I had to break away from making videos for personal reasons but I am back and in the process of adding a new vid.

[@sivz87]

Hey Buddy... is there any way that you are still able to reply to this video? I have quite an important question and really need some advise before I do go out and create a problem...

[@mybimmerspace]

. BMW has many variances for relay locations. What year and model do you have? is it a U.S. or Euro spec? On some Euro BMW's the fuel pump relay was used to power the o2 heater

[@Yarenchak]

What a beautiful video! Well done!

[@1D0N]

Interesting. As you say some cars may have only 2 relay. Well mine does. The left and middle one. I don't have the O2 sensor relay, or it located in another spot. Do you know why some have only 2?

[@dillonwells5649]

just dont put the main relay in place of the fuel relay lol just did it and next thing we know the wires on engine harness was smoking. pulled it all apart and it was the 87a middle wire on the fuel pump relay. rewired it.. and now for some weird reason my gas gauge doesnt move and sets on E

[@bravoA-su8xm]

17:33 how to jumper or look for power to pump

[@Jesusfreak39]

you have good advice Now i have a 1995 325i v6 i just replaced the fuel pump do to having the car not run just turn like it did when you was pushing start button now i also replaced the fuel filter but its not same length as the other one way smaller but what o'reilly gave me was a shorter fat one but was suppose to be for my car now the problem i have once i got it to crank it ran fine but once i cutt it off it wouldnt crank does same thing again as your push button starting method any suggestions thanks

[@mybimmerspace]

As far as I know Oreilly's only carries Fram filters for our cars and I would be very careful about that. I would suggest only using oem BMW or Mahle, Mann filters for oil and fuel fueltration. There are a lot of KZbin videos about this subject please investigate. Thanks M.B.S.

[@mybimmerspace]

If it is a Wix filter than that is fine, But make sure the fuel flow arrow on the filter is pointing toward the engine side of the car. If it is not you will not get enough fuel to the engine and it may not start or will run poorly.

[@Jesusfreak39]

mybimmerspace iv got highest brand they had and yes arrow is facing twrd engine

[@jozeeheath919]

Thank you for your video, it helped a lot! Nevertheless on my 1998 e36 323 the fuel relay is not Nr1. 1. Auxiliary Pump 2. Fuel relay 3. Main ECU relay.

[@goheat77]

Did you do s video on injectors for the m50 motors?

[@cuttyb]

where did you wire that push starter? to solenoid?

[@jimmylouangsyyotha]

if that fpr connector isnt connected, will that cause the car to not start or get fuel?

[@abilashreddy1]

Question of fuel pressure. I have a E46 330I and checked the pressure at the shrader valve on the rail. It shows up 45 PSI when I turn the key and let the pump prime. Jumps to 50 PSI after I start the car. Then when I turn the car off, it stays within the threshold for 15 - 20 min. Then I start seeing a slow drop in pressure and is almost at 15 after 45 min. Is this normal or do you think if there is a issue?

[@tommyvvirs1731]

is the black connector to the pump supose to have power when key on? cause i hook up a multi meter to the connectors the white has 11volts and the black has none? 1995 BMW 325i sedan

[@garyharper2992]

Where can that t barb adapter be purchased?

[@timlockhart8743]

so when I jump termals 30 and 87 and I can hear my injectors supply fuel,is that normal or is there an issue with injectors?

[@itsmruniverse]

I have a 95 325i sedan (8/95) and it has a white top with a non ridged tube. I am having an issue with fuel pooling on top of fuel pump and spilling over. I was wondering if the wrong fuel pump could be my issue. I was planning on changing the o ring gasket and fixing any hairline cracks but was wondering if I needed to cap the hole off?

[@sctadych]

Gregory Johnson new clamps are what you need or jb weld the ends of the hoses=no more gas pooling on top

[@gouveiapedro]

Hello everyone. My E36 318 tds (M41) discharges the battery if it stays 3 to 4 days sitting on the garage. Battery is new. I've checked the relays and noticed that the System Main Relay (relay nº2) and the Oxigen Sensor Temp Relay (relay n.º 3) stay on after I remove the key from the ignition. Anyone knows if it should be that way or if they should turn off? Thanks.

[@MilkThatEmo]

Hey buddy. Do 325i relays (fuel pump, main, etc) and the fuel pump itself fit a 318i? They are both '93.

[@GrassBeetle]

Hey. is the relay for the fuel pump the same as your main?

[@myfreespace3583]

good video. i'm trying to figure out why my car won't turn on. people, i recommend you to disconnect your battery before pulling or installing any relays.

[@bigmarc977]

what are the symptoms of having a bad fuel pump?

[@bob1307]

How do you know if you have a Euro spec BMW or U.S.? I used your troubleshooting advice on the fuel pump relay, bridging 30 to 87, but the secondary air pump turned on and I didn't hear anything at the fuel pump. Are relays in different positions depending on spec?

[@bob1307]

Great video by the way. You are very thorough.

[@Ivan-rs2xt]

you might want to check your VIN number on www.realoem.com so you know, of course there are plenty of "clues" that your e36 is an EURO or an US specs.

[@OneBulletProductions]

Hey i am having trouble, just did swap into new e36 and the motor cranks but it does not spark and there is no fuel to the lines. please help!!

[@trentpope6239]

Tried switching the horn relay with the fuel relay and it shorted my harness:(

[@antawnjameson1387]

Great video

[@xTorkis]

Isn't this m52? Becouse I see intake vanos. M50 had no vanos. Or am I wrong?

[@keith3500]

+Martynas Vaidila 1992-1993 (early 93) M50 were non vanos engines then BMW started incorporating vanos into their engines.

[@seanmccormick8193]

Martynas Vaidila my M50 has vanos

[@Ejroy09]

Thank you, this was a big help, and plenty of useful info

[@ATCRyderX]

I honestly think someone (if not me) has screwed up the relay placement on my e36 325i (cabrio 1995). My fuel pump relay has 5 Terminals - Yours has 4. Any ideas there? Anywhere I can get a proper relay # & placement diagram anyone know?

[@gorjkiy]

My 325i 1993 has also 5 terminals, and fuel pump relay is replacement with not original one , vehicle is loosing power.

[@FOTOYVIDEOPINEDA]

I switch the relays the he saID AND MAN something burn under the dash by the passenger side so now i am worse than before

[@Vgk36]

He never said to swap the MAIN relay with the fuel pump relay..

[@haithamhashim]

thank you for your ,excellent explanation

[@khamtp42]

thank you so much very good video love it you explain clear

[@Maq_Man]

dude, you are Aeeee genius, how can I retain you?

[@StalinsFather1945]

Thanks for the vids keep the good work up make more videos im thinking of installing quad vanos system in mine perhaps you can make a video about that anyway great vids you the man

[@petarcrakov8995]

Ok👍👍👍

[@Jesusfreak39]

hello sorry didnt know u wrote me back iv also have a board trying get help ...www.bimmerfest.com/forums/showthread.php?p=8189448&posted=1#post8189448 has new fuel filter, fuel pump, main relay, cranksenser, camsaftsensor, spark plugs, etc I was told might have bad DME? due to only will crank when check engine light comes on 2nd position... thats when it does come on, What makes that check engine light come on?

[@mybimmerspace]

No problem, whether it be my help or all of our help together on KZbin; knowledge is power for BMW repairs. Thanks M.B.S.

[@bennyfizzle]

alright

[@ricgomez1]

oh man...this guy with his straight out of the book wanna be knowledge is annoying. He has very little experience, yet he decided to make a "how to" video.
