BMW E36 How to diagnose fuel issue

[@TooflyJesse]

Great job Man, I appreciate your help even 7 years later

[@F4br1qu3]

Finally a straightforward, easy-to-understand,very professional, no bullshit/timewasting channel on one of my favourite subjects :) Keep up the great work, big up from Hungary!

[@ThePahndafoetoe]

Dude, bless your knowledge. I was worried about the five prong being the issue. So much stress relieved, your good karma levels must be insane with all the help you’ve given. You my guru for my 95 325i convertible.

[@e36fanatics29]

Thanks a lot! I'm glad the video helped.

[@80sOutrunFan]

Love you videos @E36 Fanatics. IT guy here but love learning about cars. I bought 2 1995/1997 E36`s with all kinds of problems to work on / learn :)

[@skilljoy244]

This saved me a bunch of time and energy, thanks so much man!

[@emilianobryson9608]

instablaster.

[@ShqipeKnocksMMA]

There was no noise from the pump though

[@vrilthisc368]

If fuel gauge read empty ...how to tell which fuel,sender faulty...left or right side???

[@getawaycar3]

Love the simple direct info brother keep up the good work. 😎

[@e36fanatics29]

Thanks a lot glad it helped!

[@MJ-so9tc]

hey mate i dont have those 3 relays outside of the main box? is there another location for it?

[@cizbarca]

Why does the 5 prong cause a short and a smoke. Id consider adding a note or something to correct yourself 96 328is

[@sunny-bhai]

What is the relay number for the middle white relay, where the fuel pump relay was located my brother knocked down the engine bay so my car has been just sat there for years. BMW can't tell me. Also is the pump in the tank always on?

[@devonyoung9985]

Royal explanation maybe this can help me fix my E36 1993 bmw 325i

[@dewholdingsllc1050]

start with a fuel filter on any car. Then test fuel pressure as per specs, to test use a loaner tool checked out at most parts stores, if fuel pressure but leaks down then fuel pressure regulator may be cause, if no fuel pressure then yes, check the electrical fuse and relay. 5 pin relay is not correct, it turns stuff from hi- to low. not off. 4 pin relay turns stuff on or off. if you have new fuel filter, test and have pressure then test fuel injectors either on or off car. clogged fuel injectors will cause misfire or non-start

[@7heheadznot7he7ailz]

My fuel pump is new and was working but it sat a few more months to get some other things fixed (93 325is) I put a new battery in today and went to prime it and start it but I’m not hearing the pump come on so I went a checked the fuse 18 and it was fine . I replaced the relay anyway so it’s brand new but still no fuel pump power ? Heeeellllp!!

[@7heheadznot7he7ailz]

Was also wondering ( I should still hear the pump on even if I haven’t changed the filter yet right? How do I check for power at fuse 18 with a volt meter ? Should it be on continuity? Or volts DC ? So many questions and I gotta get to work lol HEEEELP

[@Reedstick]

What about the fuel pressure regulator? My E36 M50 is having the same problem, it starts with starter fluid but does not stay on. I have no clue how to test the pressure regulator before I bite the bullet and buy a new fuel pump.

[@kceegray7046]

Did you ever figure this issue out brother? Im going thru the same mess.

[@0346-p1s]

Try hooking up the 39.95 OBD2 scanner and look for after scan for option on car No Air. this means they shut down air intake.

[@0346-p1s]

mechanic's dot that when they want to charge you high amount of money. by shutting part off. or fuse off !

[@0346-p1s]

if your wondering what I am talking about Autel has inventory check says air in chart checked and X if it's bad ends in report if not it's off doesn't but mass air flow also on check if it says off then in airintake the mass air flow sensor if it says off it been shut off from computer. if it's bad it will be in report for codes problems

[@juniorrat17]

Hey my car dies randomly whilst driving I replaced the aternator and fuel pump but it still happens after like 2 hours of driving

[@GurillaRon]

Mine only has 2 the electric plug and one hose. There is a third one but it’s has a cap on it.

[@BennyHueENT]

You can use the fuel pump relay from an e30. I have an m50 in mine and still use the e30 relay

[@kim158]

any suggestions for a good fuel pump and filter to buy for a 318?

[@jgogetter]

I actually know you can't cuz I have a 96 328is and my car started making all kinds of funky noises when I put the five prong in not to mention the smoke coming from underneath the windshield wipers

[@marshalldelacruz]

j187gogetter187 that’s what happened to me. Were you able to figure it out? Smoke came up from mine, not so much the funny noises.

[@globallaprodructions7829]

I tried to replace a fuel relay on my 96 bmw 328i and the wire leading to the ecu burned out?? What would do that

[@jasenhayes1710]

replace burnt wires andcheck for shorts in the engine harness

[@dowerkgaming1229]

Pin 86 did the same for me, even after replacing it and the relay. You find a fix for this?

[@cizbarca]

Why did it short? Did you ever find out? Is the manual wrong?

[@ns_shadowf4i]

I have a 1995 325i e36 sefan.and i just did the ews bypass by cutting wire 7 and my fuel pump is still not turning in. The fuel pump fuse is fine the fuel pump works when i jump positive feeds to it. Also my injectors arent firing nor coilpacks. I have no idea what the problem is. Not sure if its my cps or what but i reakky ned help because ive been going at this thing for 2 weeks now

[@jasenhayes1710]

95 is obd1 put wire back together make sure check engine light turns on IF NOT IT COULD BE THE FUSEABLE LINK; PUT in the RUN POSITION TO SEE IF CHECK ENGINE COMES ON ,IF NOT THEN LOOK FOR THE FUSEABLE LINK FOR THE DME .COULD BE IN THE TRUNK ON PASSENGER SIDE UNDER INSULATION .OR UNDER PASSENGER SIDE SEAT OR UNDER THE PASSENGER PILLAR TO PASSENGER DOOR. YOU A DMM TO SEE IF DME IS GETTING POWER ANYWAY TO CHECK WIRES.HAD THIS PRBLEM WHEN I SWAPPED MY 318 TO 325.ENDED UP BEING THE DME BEING BURNT OUT AND THE FUSEABLE LINK .HOPE THIS HELPS.BEFORE ALL THIS CHECK FUSES AND DME AND FUEL PUMP RELAY

[@supabiscuit]

Checking for voltage at the pump before replacing wouldn't be a bad idea as it's non returnable

[@artisticwolf8746]

Hey bud my car was cranking but wasn’t starting I changed the CPS the alternator

[@hgvhdhdfhsghgshsdg]

Hey, how many amps/volts is the fuel pump relay?

[@gianpieroennamorato2737]

Great videos! I have an E36 318is can you suggest some improvements I can do?

[@e36fanatics29]

Gianpiero Ennamorato performance enhancements or specifically maintenance parts?

[@gianpieroennamorato2737]

E36 Fanatics performance enhancements

[@e36fanatics29]

Dyno tuning/performance chips give you pretty good bang for the buck, normally I'd recommend an upgraded radiator, but on a four cylinder you don't need it. Cold air intake, upgraded fuel injectors, bilstein suspension. You can really get into performance stuff, but it gets extremely expensive. I would just start with a cold air intake and a tuner.

[@gianpieroennamorato2737]

E36 Fanatics tanks for the tips ;)

[@BennyHueENT]

Watch the hooligan channel

[@esti5506]

You forgot the fuel pressure regulator. Thats important to check too. And i have a 99 318ti, but i only have 1 hose attached to my fuel pump. Not sure if thats normal.....

[@w.j.bendellr.c.flying.1037]

lo ma . I have a question for you, my gas tank on my 328i is not holding pressure, new gas cap, new overflow canister, and still not holding pressure, check engine light keeps coming on! I took a gas sniffer around the hole car and it didn’t pick up gas smell. I NEED HELP please get back to me.

[@esti5506]

William J. Bendell for my car, i have alot of fuel lines including the fuel filter, diverter valve and fuel pressure regulator directly under the drivers side side skirt. These components are covered by a think metal cover, and the cover is held on by 4 8mm bolts. You should check those lines, the clamps, and possible a fuel leak. There is also a vacuum hose attached to the nipple on the fuel pressure regulator. If that hose is damaged it could be your problem.

[@bruveris14]

i have fuel system problem. A fuel pump was working a day ago fine but today it is not. I have already checked all fuses and relays but they are fine. Fuel pump is working fine when i test it with battery and its geting power to the wires that comes to it but when i try to start a car it does not turning on.

[@mazdamike8496]

ews problem?

[@larrybeets5795]

I have a 97 BMW 318ti. I changed the fuel filter. But it is still losing its prime and hard to start. Once it is started drive it and give it over half throttle it falls on its face.

[@eobakaboymano]

my 92 325 has the same issue.

[@Everydaycali]

@@eobakaboymano did you guys ever figure out? I have a 97 ti too

[@HuckitMedia]

awesome vid, thank yo!

[@AgainstEmpyre]

@e36 Fanatics I own a 93' 318is E36, i'm stuck.. i am having a similar issue where i can crank the car but it will not start up. I just replaced all of the vacuum hoses, hoses that connect from the intake to the ICV, air boot, new o2 sensor, new spark plugs, cam shaft position sensor, fuel filter, fuel pump relay, and my fuel pump is not the original apparently it was replaced a month before i got the car back in July. When i try to start the car i can smell fuel that leads me to believe that the fuel pump is working. I bought a Peake Research OBD1 code reader and when i plugged it into my car i got a code that reads E-10, apparently that means that the car does not recognize the code reader. I am not getting spark from the spark plugs, i pulled one of the new ones and put the ignition coil sleeve over the plug and tried cranking it while i had a buddy rest the plug on the engine block to see if it had spark but no luck. The coil packs seemed to have been replaced on that car pretty recently as they are aftermarket and in fairly new condition, the only other thing i could think of is maybe i have a bad DME. Im so fucking frustrated right now im out of ideas on how to get it to run. Any ideas? Thanks btw love the channel and all of the helpful tips and tricks!

[@e36fanatics29]

Are any of the plugs getting spark? If none of them are getting spark and the wires have already been replaced sounds like you may have a bad coil pack. How many miles does it have?

[@JoseVargas-sc2bv]

Did you find what was wrong with it

[@Cobra_527]

I have a 1993 325i and I have raw fuel coming out the exhaust, terrible mpg I go through a quarter of gas in like 7 miles if that, won’t always start the first try, loss of power, and just smells like gas. I changed the spark plugs and fuel injectors and checked the fuses always I can hear the fuel pump when I go to start it but I have no clue what to do now I need help

[@e36fanatics29]

You got the black smoke?

[@e36fanatics29]

FPR, test the fuel pressure regulator. Any codes for an 02 sensor? If not I'm putting my money on the FPR.

[@Cobra_527]

E36 Fanatics Currently the muffler this off so it’s coming out from underneath the car but I’ve looked and haven’t seen any smoke. The only time I did was when i changed my spark plugs there was oil on them and on the coil packs and the smoke went anyway after 5 minutes of it being turned on

[@Cobra_527]

E36 Fanatics yeah a friend of mine did the obd1 method and said he didn’t remember the code it was either a o2 sensor or a vacuum leak but he was leaning towards o2 sensor. I never really worried about it cause this was months ago and this problem just started

[@e36fanatics29]

That's just your valve cover gasket no big deal, if you have that bad of a fuel/air mix either your 02's have gone really bad (normally throw codes) or your fuel pressure regulator. Humor yourself and check the air filter anyways, if the air filter is EXTREMELY clogged it can cause a bad mix.

[@mexicodriftgarage2014]

I have a 94 bmw 318is. My problem is i step on the gas pedal but dont accelerate that and today the cel started to show on dash. But it goes away when i put it on gear. Its automatic. @e36fanatics

[@e36fanatics29]

What's the code? First thing I would check if the throttle is opening, could be tps sensor as well.

[@chinmi101]

So whats the problem for that car

[@richardhylton-gordon3747]

Great video

[@timothyivanhoe1448]

i have 1994 e36, when i first started the car it does this limp mode(when first starting the car in the day it would also need a couple cranks before it really starts), wont accelerate and it also has an unstable swinging rpm. after idling for a moment, the car will start and move fine after i turn it off and on again. could that be a problem on the fuel pressure regulator?

[@derissuprapto]

Change fuel pump & filter. Check relay fuel pump

[@lesukable]

I changed fuel pump and it still makes no noise

[@e36fanatics29]

Did you check if its getting power to the pump first?

[@jonathandeclercq6328]

Hey, I have the same problem with an 316i. No fuel or spark. They told me it could be the EWS module. Did you solve your problem???

[@Stormnorman15]
