Golf IV / Jetta IV :: No Start After Replacing Fuel Lines To Rail In Engine Bay
Aug 16, 2016
Yesterday , my feed fuel line was dry rotting and leaking gas so I bought 516 fuel injection hose and replaced them. Pulled fuse 28 , started the car and let it die to release pressure , fixed the hoses and put the fuse back in and now it just cranks forever. I have spark , and I'm getting fuel just not sure if it's adequate pressure. When I open the door the pump did sound a little funny when it primed. I'm gonna pull it out and check it later but right now I'm completely stumped. I did this last night around 8pm and it's 4:30 am the next morning and still not start.

I'm looking at replacing the fuel lines in my 94 F150 and the big question is what to do with hooking up to the fuel lines coming out of the fuel pump hat and the fuel rails? Ford uses a specialized pressure fitting on it's custom fuel lines. I think there may be some third party fittings that would replace these, but I'm not sure. I could use a standard hose and cable clamps, but I just don't trust that kind of connection for a fuel line.

My mk4 sat for a while and upon starting up was misfiring. I checked for pvc leaks and didn't see anything but went ahead and cleaned my maf sensor and decided to pull my coils. Cylinder 1 had oil on the tip and around the spark plug which to me spelled out a bad valve cover gasket. I got all the parts to do the inner and outer gaskets and replace the coil and spark plug, however we got a snowstorm and my luck a rabbit got in and ate the wiring on one of my fuel injector connectors.
So went ahead and put on the new gasket, replaced the coil and plug and bought a new Fuel Injector Connector and spliced in onto the Injector "Pigtail'. I double checked everything was reattached properly and let the gasket sealant dry for 24 hours. I went to start it tonight and after trying to turnover it completely cuts out, wont even start up. I'm extremely frustrated at this point and am thinking the rabbit must have gotten to something else unless I did something wrong in the process of repairing.

Did the cam sync replacement on my 96 explorer awd 5.0 l had the tool dropped the sync got it back to where the last one was. Followed the procedure pretty close I did forget to remove the battery cable. So here is the issue I now have 0 fuel to the rail. is there something I might have messed up or left unplugged that would cause this. Did my fuel pump poop out the same time my sync did. I am stumped as even where to start .

I have a 99 f350 super duty with a v10. I drove it Friday night, but it wouldn't start Saturday morning. It is turning over fine, just no start. I have no pressure at the fuel rail. The pump does its little key on run. I can hot wire the pump at the tank, and it pumps. It builds up pressure after the fuel filter. I found that out when I changed the fuel filter. Will the pressure regulator shut off the fuel to the rail?

I cant find the port on fuel rail to get a fuel pressure reading.it is nothing like my tarus.saw astem sticking up on front right of rail but it has some kind of covering over it. It is a 2005 freestar with the 3.9 motor.

I have a 1994 volvo 850 turbo wagon. While replacing the pcv breather system, I dropped a little metal clip that attaches the fuel line to the fuel rail with a t25 torx screw. I can't find the clip. What the part is called or where it can be found?

I have a 1987 jeep cherokee with inline 6 and multi port injection.
Sometimes this vehicle only starts when hot
Some times only when it cold
I have recently fixed the fuel leak.
When its hot or cold and not starting if i relieve the fuel pressure at the fuel rail, in most cases it will start immediately. However if fuel pressure relief does not work. I disconnect the vacuum line at the what looks to be the EGR valve or the pressure regulator at the front end of the rail, then usually starts right away.
I have not tested at this time to see if the fuel pump is failing nor have i tested fuel pressure. I am trying to narrow down the problem to one specific part. There is no problems with cranking. There is spark - coil, plug, dist cap have been replaced.
It seems the problem is with fuel delivery of sorts. It was mentioned that sometimes the heat from the engine could be heating the fuel rail to a point which turns the fuel into a gas not allowing it to atomize.

One of the high-pressure lines on the back of the rack, close to the exhaust, has rotted out. It was smoking as it leaked right under the exhaust pipe and burned off. The rest of the freshly filled fluid was all over the ground. I crawled under and got a good look at the high pressure line, but where to source these, and if they are even replaceable? I have not tried to remove it yet, but perhaps a shop could bend a new one as a cheap alternative to a new rack. I was also thinking of checking out the pick n pull for a line.

1999 Jetta 2.0L manual trans
One day out of the blue the car would not crank or start. Checked and found that fuse #14 was blown and would blow the instant another fuse was inserted. Checked all the typical locations for wiring issues usually associated with the comfort module because it had all the symptoms of a faulty module (the power windows did not work and the fuel pump didn't pressurize the system when the driver door was opened, the alarm didn't set, automatic door locks also inoperable).
I checked the dome light, trunk hinges, rubber boot between doors and body and found nothing. Put a jumper wire into the neutral start relay and was able to crank the car. I then replaced clutch safety switch, neutral start relay and installed new (junkyard) comfort module and the car cranked up, started and everything was working normally again...for about 3 weeks. Then it did the exact same thing again. Fuse #14 was blown again and would blow the new fuse as soon as it touched the terminals in the fuse box.
I reinstalled the jumper wire in the start relay in order to be able to drive the car for the last week, and then last night out of the blue the car would crank, but not start. I turned the engine over several times and could hear the fuel pump pumping and even smell fuel, but no start. 3-5 minutes later after random tries to start, the car stumbles to life as if it wasn't getting fuel, and then drove 10 miles home with no issues. I returned the 'faulty' comfort module Monday and got another one but haven't installed it yet because I fear the same thing happening with this one as the other one.
Last night after I got the car home, I plugged in the comfort module and everything worked like it was supposed to. Can a faulty fuel pump damage the control module? I'm trying to get to the bottom of this and fix the problem and not the symptoms so I'm looking into anything that could potentially cause the problem.

The Symptoms: Car decided not to turn over for my son one morning, when I came home I tried with my key and the engine did turn over but immediately died.
Turned on key to power and watched for lights like the immobilizer/key but that came on and went off no problems there, did the same with both keys and the immobilizer/security key light went off fine.
Read for codes and there was a P0320 which pointed to Crankshaft Position Sensor. Order the part from good old Rock Auto and 2 days later it came, installed, cleared out the code, tried to start, did not start.
Decided to spray some starter fluid into the throttle body to get it to turn over in hopes a new code would come out.
It did fire up for a few seconds and did throw another code, this time P0321. That code points to the same sensor I just replaced.
Figured I would check to ensure the fuel pump and relay were working so I wired from positive and negative battery terminal to the outer plug clips at the fuel pump and I heard and felt it click. Not sure if it should prime and make more than just a click.
In my other cars you can clealy hear it prime for more than a second so not sure if the fuel pump is really the culprit here.
The car has 125K and the pump is original I can see.
I did check the relay fuse under the drivers side dash and I can feel/hear it click when I turn the ignition on.
I also did check all of the various fuses in the side compartment that have to do with the engine, they all look good and tested with multimeter as well.
So now I did order a new fuel pump, what else to try out? I did change the fuel filter at 100K so do not believe that is causing the issue. Not sure if the fuel regulator by the rail could be an issue.
It seems like all of a sudden fuel is not being delivered and with faulty injectors or plugs, they throw a code for misfire etc. Also starter seems to be fine, no griinding/smoke etc but was thinking about taking it out and over to Advance to have them check as well.

I have a 2005 Golf GL trim 2L SOVC. For months now the car won't start on the first try. One must let off the key and disengage the starter then reengage. It always starts the second try and never starts the first. Once the engine runs for a few seconds, if you turn it off, then start it again, it immediately starts. It's never a problem en route. Only if you let the car sit for a while, say 8hrs or more, (when the fuel pressure dies) do I observe this "no start on first try" behavior.
I recently replaced the plugs and fuel filter and cleaned the throttle body. It's a little better now. It stumbles like it is going to start on the first try after sitting but doesn't.
I exposed the fuel pump and measured the voltage going to it. When you turn the key to "on" position, the engine computer put's voltage to the pump for about 1.5 seconds and that's it. So while you are cranking I guess it expects that 1.5 seconds of pump operation is enough. I put my fuel pressure guage on the port near the injectors, and, as I suspected, the pressure only builds to about 28lbs. On the second try it gets up to 40. Once running it's about at 45lbs.
Sounds like a firmware bug to me.I'm considering wiring in a switch that I can toggle to deliver more on time to the pump inititally - maybe 3 seconds? Is this normal?
I noticed that when I put the fuel pressure gauge on initially there was zero pressure. Is this normal?
Shouldn't a check valve keep it at pressure? Where is the check valve located? I'm also getting a P0171 code "engine too lean". I repaired a hole in the air hose going from the air pump to the throttle body - still get the code. All hoses look good.

I own a 2000 Jetta VR6 5 speed. Car has over 300,xxxkm on it, with documented maintenance including chains within the past 12k. Car has intake, 2.5" resonated exhaust, stock software.
I have recently noticed that the car has a cold start issue. Its winter here in Canada, so in the morning when i go to start the car and let it warm up for a couple minutes, the idle is choppy at first and then evens out at around 900-1k rpm. If i try to blip the throttle, or even hold it (half way or WOT) the car just wants to bog out, EXTREMELY rough idle. It will eventually, after about 2 mins of idling, go away and i can drive.
I have absolutely no issue with allowing the car to idle for a few mins to warm up, but i know for a fact that whether a car is cold or not, it should be able to rev freely.
I also have horrible fuel milage. I use 91 octane, and average about 250-300km per tank. 70% city 30% hwy driving.
The following parts have been replaced in the past 1200 to try and resolve the issue
OE Mass air flow sensor
OE spark plugs
BREMI wires
OE Bosch front O2 sensor
I have scanned the car several times, which led me to change the parts i did. Only had a CEL once and it was for the front O2 sensor which i just replaced. Any other codes were for random multiple and a cat efficiency fault. Again those were fault found off a GFF test done at VW, they were not enough to trigger a CEL, but i still changed the parts.

Going to replace brake lines tomorrow and would like to confirm the torque spec on the actual banjo bolt as not to break them but also don't want to leave them too loose...

2005 1.8t gti wont start. The other day I was driving on the highway when a thin plastic type wrapping got caught in my serpentine belt. The car immediately died and I hit the gas and nothing and with no power steering i pulled over to the side.
Timing belt was done with water pump and tensioners
Spark plugs and coils are brand new
What fuel line to disconnect to test if the fuel pump works? Like I said in the title I cant hear the fuel pump priming. The engine was running 100% before this 2 techs saw it and the vw dealer i workrd at looked it over.

How to replace the 2 "drop down" rubber brake lines on a '13 250. They appear to be secured to the bracket that looks like is the bracket that's holding the DEF tank on. And by the quick look without much digging in appears as though I have to take the DEF tank out or significantly loosen it to get at them. I'm no neophyte when it comes to this stuff and will take the DEF tank out of necessity, was just wondering.
