thanks for explaining I have a Suburban 2012 it shut down in the road when I made OBD test it gave multiple codes one of them U0073 data bus comunication , P069E fuel pump module control - Mil activation requested , P2635 fuel pump low performance , P0108B fuel pressure sensor B and of course the delay start engine my question where is the fuel valve regulator in Suburban 2012 shuold I replace it , is the fuel pump is broken and need to be replaced or updating online Or I have to fix the bus comunication Bus before to solve the problem thanks in advance .
@drcoolautofix a relay either sticks open or close. They work like points. " If you know what points are?" 99% of the time when the relay goes out, they stop while open. If they stick while shut, fuel pump will stay on as if the ignition switch is on. A RELAY JUST OPEN AND SHUTS THE CIRCUIT. Please do not mislead people with false knowledge. Do your research and teach yourself b4 trying to teach others
I have an issue whit my fire bronco 1987 they gave 2 fule pumps that external wen I open that key switch they keep on never shout off and I hace code that saide secondary fule pump circuit failure any idea wath this means
I have an 06 Honda stalling out when i shift gears. I was told it was the tcm. But i also smell gas as the car is in idle after starting. And i jear squealing (high pitched sound) under the hood. I cant find anything specific. I can fix it myself if i know wtf it is. But i keep getting mixed info. Idc im not paying a mechanic hundreds or thousands for something i can do myself lol. I need a diagnosis device. The was hit in the back twice also. Once before i got it and then after. My husband spent off the highway ramp and hit the back. So i actually thought it was the pump. But i also have no leaks.🤷🏾♀️
I have a toyota sai 2010. It doesnt have a fuel pump relay where it should be as it says on the relay diagram , but it runs anyways. Im experiencing these symptoms but cannot find the relay to fix. Need your help
@@drcoolautofixI checked all the fuses just now !! With the screwdriver type tester light 💡!!! The (20) fuel pump fuse didn’t show power the light didn’t come on - but someone told me it will only show power when the truck is started
Fuses and relays are two different things. Fuses are smaller with a metal contact and a plastic housing, and are cheap to buy,test and replace. Relays are larger, more expensive,and harder to test. I hope that helps

A few years ago you never ask for this kind of videos to fix your car , all new stuff sucks, looks beautiful , but I like ugly things and secure
Well technology has evolved so much?
It's not beautiful it's ugly the older stuff has character and is beautiful it to mention its way better and lasts longer
I have Isuzu dteq 4jk1 engine I replaced New fuel pump and now injectors and new crankshaft sensor but still not starting what could be the problem?

Fuel pump and it filter is what you need to replace first then test drive
@@drcoolautofixthanks
If fuel relay is bad, your car will not start.....

@@davo8802, how do you know if it's the relay or the pump that is faulty?
Thank you sir youve enlighten my mind.
Can the faulty relay blow the fuel pump fuse ?
This is happening on my 1990 BMW E30 316i . It got worse and seems like a hard short circuit.
Yes
@@deanwoolston4794 The problem was the fuel pump. I've replaced the fuel pump and it's fine. Car has a bit more power as well.
Thank you.

Bad fuel pump creates short circuit
@@drcoolautofix Definitely. 👍
Very informative and helpful. Thanks!

Check fuel pump and filter

Hi, it can be the relay shut off and the pump continue to get on; making “zzzzzz” noise even with engine off???

Might be the fuel pump itself.
