Don't just throw parts at a problem. In order to truly diagnose the problem with your fuel system you need to understand how it works. If your car has a slow start condition, chances are you are leaking fuel in one of three places. Fuel injectors, fuel pressure regulator, or the check valve in the fuel pump assembly are the places you need to verify where the problem is coming from. In this video we will explore these areas to find where the leak is and then how to fix it. Hope you find the video useful.
Here are links to items I used:
fuel pressure gauge: amzn.to/2ugxx2l
nylon fuel line (5/16 O.D): amzn.to/3bltHWm
fuel line adapter for 5/16 nylon hose: amzn.to/2S5clFB

5/16 one-way check valve: amzn.to/2Sm6oD3
bicycle pump: amzn.to/2OwhZOH

Somehow I didn't realize until now that a standalone check valve was a potential fix for one built into an in tank fuel pump. My dad's 2001 GMC Savana 1500 5.7L has been experiencing long crank times for quite some time. I already ordered a fuel pump, but we've been trying to schedule a time for a buddy with a lift to help out. Today it decided to stop starting altogether. I was able to install a Dorman check valve from the local Advance Auto Parts along with an extra fuel filter, hose, and clamps, then start the engine with starting fluid. We ran the engine for a couple minutes, then shut it off, and it was able to restart again right away without help. We shut it off, waited an hour, and it was again able to start right away without help. This gave us the flexibility to run the full tank of fuel down some and get it scheduled with the lift. Thank you!!

Hind sight is 20/20 my friend. When trouble shooting a vehicle it’s in ones best interest to start with the least invasive step first and proceed in succession until the problem is solved, you will regret skipping steps in the future, try not to assume either, it’s not a good look.

Extremely useful demonstration. Fuel pressure diagnosis demystified. I have this exact starting problem when the engine has been sitting a few hours, now I know how to solve the mystery. One thought, there is a potential fourth source of a leak, the unions at the tank, fuel filter, between flex and hard lines along the plumbing, and between the rail(s) and individual injectors. Being an external leak, a visual inspection with system pressurized should find it. Hopefully before something catches fire...

Best description of fuel pressure loss areas I have ever seen or heard of ; Toyota has a bulletin out regarding 2002 Tacoma 2.7 L engine that has a fuel pump check valve problem which fits the description of the problem I am having with Tacoma. I told a few mechanics about the inline check valves I use to used many years ago and they don't understand me??? You are first class as I was a mechanic for most of my life dating back to the early sixties into the late 80's.

You're great at a lot of things sir. It's obvious that car diagnostics is one of them, but narrating, editing, problem solving and solutions. You name it. I'm very impressed and super thankful I saw this. I waiting 12 hrs for a tow last night.. 12!! Finally this morning a security guard patrolling the area was able to lend me his phone and i was able to call home and get us picked up. Ohh did i mention my 8 year was with me? Thanks Mercury. Anyhow, 2013 Ford Flex that I've been driving the hell out of lately is rapidly wearing down. I suspect an issue with the fuel pump/ lines etc. I know a good indication is that initial sound of "air" or "activation sound" you hear prior to the engine cranking as you turn the key to the ignition. I DO NOT HEAR THAT SOUND. I'm gonna use your video and rewind the hell out of it as many times as i need to, and hopefully im able to diagnose this isue. Normally I'd leave this for a professional but times are tough.. REALLY TOUGH and that's just not an option at the moment.. it simply isn't. So i greatly appreciate this video. A quick question, I'm sure there's a fuse behind that wiring for the fuel injectors. Could something as simple as a bad fuse be the issue?

@davidbrewer7937 Жыл бұрын

had to do this on my 2016 Tundra this week. There is no schrader valve to test pressure, I cobbled something together by teeing into the line, set a gauge in there, sure enough low pressure. Tested the regulator by removing it & using an air compressor to slowly raise the pressure up until it passes & regulates the pressure at 50psi. Now to prove the pump.... I made up a small un-vented fuel tank (pressure tank) using a length of 1-1/2" steel pipe & some fittings including a cap with a shrader valve installed into it. Filled the pipe up with a couple of pints of gas & pressurized the test "tank" using a pancake compressor on the seat next to me to supply the fuel rail at the engine at 45-50psi. Wahey! I could now drive the truck around... Diagnosis proved, just waiting for a new pump to arrive now. Dropping the tank with a hundred litres of gasin it was another job though, there was no way to siphon or drain it in situ!
