I have Golf MK4 variant 1.6 77kw BCB 2005y
When i crank engine i hear it fire immediately for a fraction of a second, then it carries cranking empty few turns and then fires again.
Happens only on a first start after standing still few hours.

2000 1.8t 5 speed Jetta ... The car has run fine up until recently when I started having some starting issues. It was intermittent, and got more frequent and longer. The car will crank but not fire. In the beginning, I could crank it for a few seconds, turn off and turn back on and then it would fire like nothing happen. This continued to happen and progressively get worse until I could not get it started, I could smell fuel which lead me to assume I had to spark.
Today I went out to swap crank sensors but only tried for a little while and cant really get my hand up there. So, I disconnected the battery for a while, went back and connected it, and it started. Up until this point I have had the same 2 codes, over/under boost, but the car has always ran with them present. I scanned today and got a p1545 Throttle position sensor code...But only got that one time. Ive been messing around with disconnecting and reconnecting the battery and among one of these times, the EPC light came on and would not rev passed 1k rpm. turned it off, turned it on, and it was fine after that.
Im sure I have a sensor about to let go Im just not too sure which one it is. I dont have vcds and am not getting a low signal code from the crank sensor with the scanner I have.
My '08 2.7 has difficulty starting in the morning. It makes the normal cranking noises but won't fire up immediately. I typically let it try to catch for 5-10 seconds, pause, and try again. Then I wait a minute, try again, and everything starts fine. Then it'll start normally the rest of the day.
Pardon my ignorance, but isn't there some sort of compartment that holds fuel into the engine with a check valve that keeps it from releasing back into the tank? Could it be that this valve is leaking?
Or does it sound like I need a whole new fuel pump? I tried to find schematics, but had no luck. I tired hmaservice.com, but I'm not willing to install the Adobe SVG app (obsolete and security risk) to view the documents.
2003 1.8t gti ... Today when I got in my car...it fired up perfectly normal but when I got in it from leaving school it took 5min to fire up. The engine turned over but wouldn't fire all the time as if the spark plugs were bad. So I bought new NGK spark plugs and had the same issue just a little bit ago.
I know the obvious thing would be to change the ignition coils but they're out of stock everywhere so I have to have them shipped. My question is is the ignition coils the problem? They looked a bit worn but nothing serious.
How long does it take to fire up the engine?Just got mine running today and I'm new to 6.0. It took about 4 seconds the first time, and considering this was a used engine I figured that was very fast to fire up. However, subsequent starts which I had expected to be less cranking are also taking about 3-4 seconds. I haven't had any experience with an oil actuated injection so maybe this is typical for the design?
View 14 RepliesAfter running to operating temp, if the car is turned off then restarted (like you would at a gas station, which is where I notice this) the engine will turn and turn and turn but not fire. I have noticed that stomping on the acceleration will cough it into life during this procedure. This doesn't happen every time and I have recently run high octane gas during a long distance trip.

I drove my Aurora 300 miles one morning and when I arrived home it was running fine. I shut it off and went in the house and after 10 mins, went to leave again. It just cranked and cranked and wouldn't fire. I assumed it was the fuel pump and upon pricing one out, decided to wait and just plated another car. The Aurora sat all winter and now with the weather a little nicer, decided to try and fire it up last week. It cranked for a few seconds and there was a small explosion under the silver cover plate on the motor. It sounded like a backfire. It did it 2 more times and I stopped trying. It seemed to be coming from the intake and the foam on the under side of that silver plate is singed on the side by the power steering resovoir. Is there something there that could be pooched? Could it still be a fuel pump being that there is something exploding there? Could it be a fuel rail issue? I have read that there have been recalls. And where is this fuel pressure regulator?
View 1 RepliesI just bought this car... today... ran great until I got a few exits from my apartment (I think the car knew I had my hopes up for successfully making it home) and all of a sudden the car shut down. There was no smoking, shuddering, or weird scents of any kind. Had my girlfriend following me and she said she didn't see or smell anything... the oil level is good, pretty clean... coolant is clean and pink... timing belt was just done about 5k ago... but she cranks and stumbles a little but that's about it. Battery died from repetitive attempts at starting and now I think that old girl needs to be replaced... but does this sound like a crank position sensor issue like I'm guessing? or possibly cam position sensor? Also might add that the dipstick and oil cap hole had a little smoke coming out of it when I pulled it to check the oil situation... B5 1.8T wagon
View 11 RepliesPreliminary information: the vehicle is a 2003 jetta (gli), My drivers door ajar switch is broken and the ccm recognizes it as closed at all times (open circuit), also I was hit in the rear at about 40mph by an f-250 a week after I bought the car and I repaired the damage myself (I am not a body tech). I replaced all electrical components in the trunk as they were all destroyed as well as the trunk lid which has never quite closed the same.
.Key Fob serves no function, (replaced the battery as troubleshooting.)
.If I lock the doors VIA drivers door, passenger door or by key in door, the doors will lock and then immediately unlock.
.It seems to think a door is open even though they are all closed and the overhead lights don't come on like they would if a door was open.
.The door ajar light was on when it first started and the light burnt out after less than an hour in (coincidence? or short? I don't know what circuit to start on).
When I parked this car 2 months ago it ran fine. Went to start it up and it starts and shuts down. I do not think its the security issue. Both keys do the same thing.
Battery is new recently. There are no MIL lights working on the dash except the battery light. The actual dash lights will not come on. Doors will unlock but not lock. My VAG tester will not communicate with the ECU.
I have checked all of the fuses multiple times. I can hear the fuel pump prime up when the key is turned on. It appears that there is an electrical issue. I took the connections off of the ecu, waited a bit, check for cleanliness and reinstalled also.
Previously, I have had no rough starts or other starting issues, and no issues with my battery, which is 4 years old. I left work and had some errands to run--started my car, drove about 1/2 mile. Started my car again, and drove about 1/4 mile. Started my car again, and drove about 2 miles and stopped at a gas station. Started my car again and drove 2.5 miles.
This time, my car started fine, and I began to take off (moving forward--no car in the space in front of me) and after about 5-10 feet my engine died. I haven't been able to start it since. The starter is turning well, but I don't hear anything firing, and giving it gas as I hold the key over does nothing.
Where should I start? I have a video of trying to start, I may try and upload to Dropbox and post. Car is a 2004 Jetta GLS with 247k, and I currently have no DTCs stored (checked using a generic OBDII scanner, not a Vag).
My 2005 vw GTI doesn't like to start in the cold. It will start and I can rev it just for a second before it turns off again. My ABS and ESP traction control lights are on and they only turn on when I have this problem. Normally when it does this I can let it sit for a couple of hours and it will start as if nothing was even wrong. I took it to the dealer to do a full diagnostic on it and the only thing they could find was a faulty instrument cluster and I don't think that is what is causing my car not to start.
View 9 RepliesI'm going to preface this by saying I've already had the immobilizer problem and I know about the light on the dash of the car + key flashing when you try to start the car without the immobilizer chip in the key fob.
My car has been running completely fine, I go out to start it, it fires up then immediately dies. If I hit the throttle while it starts up it will rev up but still dies even if I hold the throttle all the way open. After doing some research I was pointed to crank position sensor. Bought a new one, didn't change anything.
The strange thing about it is ever once in a while I can get it to start up and then it will run for as long as I let it, so its obviously getting air, fuel, and spark. I have also disconnected the battery and left it for a few hours, didn't work either.
To start I was driving home the other night, car just stalled out and would not start back up, at all. Just cranks over and over. Things I have checked
- I am getting a spark from the plugs
- Fuel pump primes when key is turned on
- Fuel comes out of lines, even more so when key is switched over so pressure should be ok, I have not checked exact pressure due to not having a gauge.
- I have checked all relays under the steering wheel (just visual) some had brownish on the connectors and I cleaned all that off.
- All fuses are good and not blown (voltage meter also showed power coming to a few key fuses I checked.
I am down to a few things that I have read could be possible causes
- Camshaft Position Sensor
- Crankshaft Position Sensor
- Not sure what else to really check
Have a 2007 LS460L. Recently, I notice when I start the engine, it would start and then, in a fraction of a second, it will shut off. I then have to start over again. This is happening too frequently to be something I'm doing wrong.
Took it to the local Lexus dealership and they could not reproduce it, but told me they have had similar complaints from other owners, including other models as well, with keyless starters.
2003 Jetta TDI GLI , fuse number 32 (30 amp fuse) keeps blowing immediately after I replace it. I can't start my car because of it. I do have a shorting head light and the glow plug indicator flashes with the check engine light on. This doesn't happen all the time. When it does happen, sometimes the accelerator will not work and instead of idling at ~900 rpm it idles at ~1100 rpm. I usually just restart my car and then it works again. Not sure how these issues are related but I can't start my car because of this blowing fuse.
View 2 RepliesI have a Mk4 GTI with the 24v vr6. Car wont start, just cranking for days. This all happened a week ago. I was at work, went on lunch at 12 and drove home to eat, come back at 1 and park it. 4 o clock I get off, try to start my car and nothing. Just cranking no turn over. Ive had no prior problems with this car, other than some misfires from 2 different coils, which I've replays 2 of them.
Car has absolutely no spark. Here's the parts I've regretted throwing at it because of this
-Coolant temp sensor
-Spark plugs
-Crankshaft sensor
-Fuel pump relay
I thought for sure it would of been the crankshaft sensor but I put it in and got nothing. I've checked all my fuses and they are all good. Finally got my code read with a vagcom last night and got these 2 codes
01177 no communication to ecu
01314 no communication to ecu
I also get no CEL when turning the key on "ON" which tells me ecu.
So I've kind of narrowed it down to 3 things, but it wouldn't surprise me if it was something else though. I think it's either the ECU, relay 428 for ecu, or wiring on the ecu. I swapped in a working BDF ecu and got nothing. I figured it would at least start and then cut off because of the immobiliser, but maybe im wrong. I know when my key imobiliser died it started and then cut off, maybe with a different ecu that's not married to the car is different and wont start, I am not sure. how this works.
So after the ecu swap didnt work I started reading wires. Going off the diagram here [URL] .....
I have found the following
a) pins 1/2 for ecu ground are OKAY read 12v
b) pin 21 read 12v
c) pin 3 would go to about .12 while cranking. idk what it is supposed to be
d) pin 23, which is ground to the relay 428, read .01, which is the same reading i got off the ground for the relay spot
e) pin 62 gave me nothing with the car off
So right now my concern is kind of on the relay 428. I don't know what it is supposed to read but that seems kind of off for .12v power while cranking and .01 ground. What should these readings be? should i be reading them while cranking?
I have a 2001 Golf GLS that normally starts on a dime.
It's already had replaced:
New Starter - 11/2/12Ignition Coil / Plugs - 5/22/13Rebuilt Alternator - 5/9/14New Battery - July 2015
The other day, nothing happened when trying to start her, no cranking or anything. The lights work, battery is good.
Yesterday, I depressed the clutch all way to the floor and it started.
Not sure if it's related, but I'd like to trouble shoot before I take it to a shop who's going to want to replace everything.
Car has 154,445 miles. Not original owner, so don't know how they drove it. We got it with 150k
I have a mk4 golf 1.8t that cranks but wont start. It was running fine for about a year. Then one day it will crank and not start. Since this issue has happened I have replaced the :
-fuel pump-
-fuel pump relay-
-coils-
-spark plugs-
-crank position sensor-
-fuses-
the car still cranks strong (with a jump bc its been about a month or so since its actually ran)
no fuses blown
fuel lines have pressure ( maybe have to bleed the lines ?)
2009 Toyota corolla Automatic, 1.8L NON 1ZZFE
Died while Friend was driving .
No MIL, no history or pending codes.
Verified spark with a test plug and a ignition wire tester. Has spark while cranking.
Verified engine has fuel at injectors, removed rail and attempted to start while monitoring injectors, visually fuel is being sprayed out.
Verified compression by removing #2 spark plug, inserted finger into hole, compression forces my finger out of the cylinder head.
Security light comes one initially for 2 second when key is turned on, but goes away during cranking.
Cranks nicely, wont fire or start.
Not sure what's wrong, looking for an EFI or Ignition wiring diagram.
On the wifes Santa Fe 2.4 AWD every few starts it seems to crank over longer than it should. It will usually crank right up like it is supposed to. Every few times it may take 3-4 seconds of cranking before it will fire.
The car runs great, averages over 30mpg per the computer. No codes. I don't have a clue what it could be.
