Passat (B5) :: 2002 V6 Won't Start / No Spark Or Fuel
Dec 12, 2011
Freshly rebuilt 2.8 V6
Car turns over but is not getting spark or fuel. The timing is good (checked multiple times, and I have done numerous TBs on these engines). Compression is good.
The car has sat for ~2 months. It broke the timing belt (and bent or broke multiple valves), so I know it had both spark and fuel before this.
I have gone through and double checked every connection and everything is connected and seated properly. I used a stethoscope to listen to the injectors and there is no click during cranking, and using an extra plug I checked spark and there is none. I also hooked up my inductive timing light and it doesn't sense a spark.
I have VAG-COM and there are no fault codes. I have checked all fuses and they are good. If I do the tests on VAG-COM I can make the injectors cycle, but they don't cycle when cranking. I tested the crank position sensor (and tried a new one) and it tested good (and the new one made no difference). Using VAG-COM, I confirmed that it does sense the engine RPM when cranking. The battery voltage stays above 12V during cranking as well.
A couple other tidbits of info:
The fuel pump does work (and comes on when cranking... confirmed by disconnecting the hose and pumping fuel into a can)
When cranking for a few seconds, the display says STOP and flashes the oil light (I'm assuming because it is cranking at such low RPM)
The Check engine light and EPC light come on when the key is put in the on position and turn off during cranking (like they should)
The immobilizer light comes on for a few seconds as well, but it doesn't flash like it would if it was immobilizing the engine.
After looking at wiring diagrams, it appears that the ignition coils and the fuel injectors both run off of the same relay, but I am unsure which one or even if I am right about that. But assuming I am correct about that, wouldn't the injectors not fire during the test if that was bad?

I was on my way to work and my car would not start after I stopped at the gas station. One of the people at the station gave me a jump start and I continued to work. I asked one of my co workers to give me a jump to get home and when I started the car there were sparks and a bit of smoke from the battery. We hooked it up right and it will turn over but not start. The fuses are all good, the dash lights come on (service engine soon, check engine and security). We replaced the battery, and the coil assembly (I think that contains the ICM, but not sure). I called the mechanic I normally use and he said it was probably time to buy a replacement car. My friend (the one who hooked it up wrong) thinks it might be fixable, he has some mechanic experience and stated we are getting no spark and the fuel pump will not engage. We hooked up a car scanner to it and it was unable to communicate.

2002 X w/ V10..
Drove to walmart the other day. Ran Great. Put a new battery in my spare key and tried it but anti-theft light came on. thought maybe battery was in backwards so turned it around and tried again still nothing. So tried original key and would not start. It would crank but not fire. (found a post stating that it was part of the anti-theft system to keep from just trying different keys) I let it sit for a little while and it started.
Drove home put new locking hubs in the front and took it for a drive. Started fine. Wife the next day went to work with it ran great. When she went to leave, it would not start. after about an hour it started for her and drove home with out issue. Next day I went out and it started for me first try. Then it started to just crank and never fire. After a while it started and I was able to start it a couple of times with out a problem then it stopped again. Since then I have not been able to get it to start.
I say I have no spark only cause I have tried to use starting fluid to at least get it to fire but nothing.. It doesn't sound like the fuel pump is kicking in either. Is there something that would shut these systems down that I am over looking..

After replacing the intake manifold gasket for the second time, the truck would not start. Thought for sure it was my putting the distributor in wrong. After reviewing the forums, I am sure it is installed correctly. I have spark but no start. Engine cranks over nicely, but acts like it needs fuel. I hooked up a fuel gauge, turned on the key and get 56PSI. Lower than the 60 required. The pressure then slowly goes to 50 PSI. I pinched off the return hose and had the same readings. Pretty sure I need to replace the fuel pump. Is there anything else I need to check. I replaced the fuel pump a couple years ago with a Delphi unit. Maybe this is just a weak link for these trucks. My truck has a little over 100,000 miles on it.

I have a perplexing problem and I'm at wits end trying to figure it out. I have an 03 GTI 1.8t 20th. The car has been running great until today when I replaced a few bolts with the front bumper and replaced a motor mount bolt on the passenger side mount. Everything was great until I did the work on it. I figured I had bumped the cam position sensor so I swapped it out for a new one and nothing still. I have verified I have spark and I definitely have fuel as it keeps drenching the spark plugs. I have cleaned the spark plugs and tried starting only for the car to violently sputter and misfire. No codes are being recorded and nothing else has been touched.

Working on my buddys 2003 camry, wont start, has air and spark and not getting fuel. replaced fuel pump already. If you hit it with a quite a bit of starting fluid it will fire up for a few moments and then die out, its got half tank of gas. The whole start of this is he ran out of gas and since then wont start.

I have 06 F150 5.4L with a no start condition. The truck comes from another shop with no improvement. This is whats done so far, replaced plugs, checked the fuel control module 100% ok, we have fuel pressure at the rail, we have injector pulse ( niod light ), we have spark and we have a good battery. We tore down the timing cover because of the sound of the engine turning over like it was out of time when cranking.
We did find a tensioner totally destroyed so we replaced the timing as put it back together and replaced the oil pressure switch because we get this "low oil pressure" in the info center every time, we also get gray/black puffs of smoke out the tailpipe when turning over. So to sum it up we have spark, fuel, and battery and still nothing! We even flashed the ECU and still no fire/no start.

So it finally happened...One day she was working just fine and now is dead. OK, starter is working, battery is new but there's absolutely no spark on any of the spark plugs. I wonder what could it be ?

The truck just quit having any throttle control which seemed to be ignition. Way old stuff needed replacing so I went after that. Installed complete new distributer, coil and spark control module. No good. Found spark using checker but not sure what this should really look like. While checking compression found a lot of fuel coming out of number 6 cylinder and nothing out of any of the others. Compression in all cylinders is around 120. Distributor timing at number 1 TDC looks good. I am thinking some fuel system related issue but cannot figure out why so much fuel comes out of the number 6 cylinder.

I brought the car home last night and shut it off. This morning went out and engine will crank but doesn't show any signs of fuel or spark. Removed one plug and grounded it to block while someone cranked it. No spark. I dumped a little fuel in the cylinder just to see if I could get it to cough or something, but nothing. I tried looking for blown fuses under hood and under dash but I haven't noticed anything out of the ordinary. I pulled out all relays and tapped them and reinstalled. I tried disconnecting the battery to reset ecu and that didn't work either. There are some relays marked that I don't recognize.

Was driving normal and my 2004 r32 died. It felt just like it ran out of gas. Fuel pump was not making any noise. I replaced fuel pump relay and now i can here the fuel pump making noise. Pulled the fuel pump line off and fuel is coming out the line. So now i checked for spark and have none. I have 12 volts at the coils. I ohmed out the crank sensor and have .777 k ohms. I also checked codes with generic snap-on scanner and found no codes.

Sons 94 ranger 4.0 4x4 Auto 185k got him to work yesterday but would not start to bring him home. No spark, checked with timing light, and no fuel pressure. Searched and read alot of tips from Pawpaw so I tried a few things with no luck. Swapped the relays around, inspected coil pack and plugs. CEL was not on and goes out while cranking. I have a OBD scan tool but this truck must be too old or I need finding plug. Crank sensor maybe?

As far as I know, my Passat has never had any other spark plugs other than OEM. I could also swear that those OEM plugs always had 3 grounds. My gas mileage historically averages about 27MPG in a mixed city/highway environment.
Recently, my spark plugs were replaced and now my gas mileage has dropped to 24MPG. I had a similar problem once with my previous car (1998 Jetta GLI) and it was due to going from a three ground spark plug to a single ground plug. Putting in three ground spark plugs instantly restored the gas mileage to previous levels.
I've read repeatedly that the NKG PFR6Q is the OEM plug but it only has a single ground. I realize that my memory could be faulty, but this is driving me nuts.
Alas I can't be sure what was there before versus what's there now, but I know my previous mechanic was a stickler for OEM parts. Would switching from a multi-ground to a single-ground cause a 10%+ drop in mileage?

I am new here just bought a santa fe 2002 2.4 model and its playing up it will start run for a few mins then die and wont start again for a while. the crank sensor has been renewed as has the cam position sensor the fuel pump makes the normal noise so fuel is getting threw the only other symptom is when it cuts out and wont start i check both ignition coils and neither are sparking yet there is power to both, all fuses are fine .

I have a 2002 F150 5.4L (VIN-L) that has been sitting in the driveway since February. I have been a mechanic for 30 years for large commercial trucks, and my own truck has me stumped. I'm sure I've forgotten something but I'll try to list everything I have tried so far. It started with crank no start, no check engine light, checked for trouble codes got a trouble code for the CHT(cylinder head temperature) sensor.
- Replaced the CHT sensor. Cleared codes.
- Dash lights up fine, shows mileage, and anti-theft is not flashing while cranking.
- Fuel Pump does not seem make any sounds. Hit the tank with a hammer. Nothing.
- A little fuel comes out of the schrader valve on the fuel rail when I push on it. I have not checked it with a pressure gauge.
- Attempted to start with ether, nothing, so I'm assuming no spark.
- Fuel pump inertia switch isn't triggered.
- Checked several ground connections to the frame and checked ground connections in the PCM harness. All have less than 5 ohm resistance.
- Unplugged and plugged back in cam shaft sensor.
- Checked voltage on the TPS(throttle position sensor) I'm unsure about the results, if the TPS was bad wouldn't it just idle funny and/or stall?
Fuel Pump and PCM relays in the underhood fuse block appear to be good. All other fuses and relays appear to be good. I have been swapping the relays with one I think is good, although. Searched all over for additional relays, and found 3 inside the cab behind the passenger air-bag. Can't seem to find anything in the Haynes/Chilton manual that lists what they do. They are about half the size of the fuel pump relay.
Manually grounded the fuel pump relay, relay clicks but I don't hear a buzz from the fuel pump. Id like to run 12V to the fuel pump directly to see if that's my issue, but I'm not sure where to connect it without frying something important.
I bought the alldata.com DIY guide for my truck and it hasn't worked much. I have read extensively about others with similar problems and I just don't know what to do next. My main question here is, if the fuel pump is bad, would that stop the spark plugs from working? I'd rather not replace the fuel pump without being absolutely sure.

The rear spark plug boot, the kind that goes down into the center of the engine, pops up about a quarter inch every so often. I have switched the boots and cleaned the walls of the plug area and it pops up on the rear cylinder only. This is a 2002 Passat 4 cylinder Turbo with 163,000 miles on it.

My son has a 09 Vibe 1.8L automatic and it won't start. Among other things, I also I want to check to see if it has spark and fuel pressure.
First of all, can I check for spark by looking at the signals into the coil packs? I realize that this won't actually tell me if there is spark at the plugs, but I'd like to know if the ECU is commanding spark or not. One of the coil packs was replaced a couple of months ago, so I'm fairly confident that it is OK. And it's hard to believe that all of the rest of them would suddenly have a problem.
As far as the fuel pressure is concerned, I don't see a valve on the fuel rail to connect a standard fuel pressure gauge. I'm assuming that I need to some how tap a gauge into the rubber supply line, prior to the metal line going to the fuel rail, but I'm not sure this is the recommended way.

All of a sudden my 2002 F150 6cyl, will crank but won't start. First thing I did was hook up my timing light to see if I'm getting spark when I crank. Tried a few different plug wires.....no spark. Can a coil just go out like that? I have a multimeter, what do I check to see if the plug that goes to the coil is providing correct power and input?

I got a 05 Passat I am working on. The car was being drove and my customer when to eat lunch. Came out side and didn't start. Got it to my house threw it on the scanner and it brought up 2 cam sensor codes. Replaced them and still nothing. What to try next. The car cranks over fine and it does have fuel pressure and also has spark.
