Clean the air filter? What, not bike weather yet? It has spring fever. I wonder how you're measuring these things, but you should try for a concordance from the ODB II port (the computer) and see what it thinks. I'm guessing there is a bad spark wire; if one goes over 40 ohms in operation (that is, lots of current, so be safe) it might be failed out by the computer. It might be failing to pull a vacuum because of a leak in that system. Does it turn smoothly and easily with plugs disconnected?

    Yes, check for a spark.http://www.autozone.com/repairguides/VW-... The coil gets a constant 12 volts and a ground with key on, a signal from the ECM triggers a built in module in the ignition coil, when triggered, the ignition coil operates.

SOURCE: wont start,not fuel problem

hi , i think i have the same problem as you, my engine light flashes and i cant get fuel through the injectors but i have fuel pressure and spark. try these two links which might be helpful, the first explains about the mitsubishi ecu used in your vitara, basicly saying they're **** and break down quite early in its life and the second explains how you can run your own diagnostics test using a paper clip and counting the number of flashes from your engine light, you then compare this to the chart on the web site to find your problem.

mitsubishi ecu site www.carelect.demon.co.uk/mitind.html

hope this helps you out, karl hodder

Cause is lack of oil not getting to lifters. Try using a good cleaner to flush the engine and change to a lighter oil for a couple oil changes.

SOURCE: buick regal 92 3.8L Horrible fuel mileage

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.

SOURCE: passat b5 tdi fuel delivery problem

How long are you cranking for,if you have allowed to run out of fuel, it needs to be primed, try pouring diesel into the fuelfilter, but I used tohave the 110bhp AFN passat and it would start after cranking for a while and then cut out, then start but possibly cut out again, then start and give it some throttle, should be fine after that.

1998 VW Passat cranks won't start. fuel pump works,fuel up to fuel rail, spark plugs do fire


Improper fuel/air mixture, possibly plugged up air filter?
You have 2 out of 3 of the needed components for that motor to run, and assuming your timing is correct and you have compression, it could be an air intake issue.

Fuel pump noise vw passat 1998


It's very likely that you need to replace the fuel pump. Usually, if its that loud either its sucking air (because you're out of gas) or the pump is about to go out.

1998 Passat - found bobby pin in relay switch - pulled it out now car wont start


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.



From start to end troubleshooting these problems I suggest you to check the help link below and follow its procedure: -----


Mostly all types of car no start problems are discussed here with solutions.

My car a 1998 passat vw, dont start. the motor turns but thats it. i got pushed and still no change


First you have to determine weather you have a FUEL problem or (ELECTRICAL)Spark problem ??

Pull the coil wire off or a easy to get to spark plug wire, Lay it close to were you pulled it off of (Do not hold or touch you may get SHOCKED) and crank motor (need two people) look and listen for a spark, if you see or here a spark, then go to next step which will be to check for Fuel (gas). Be very careful when checking fuel, as most lines are under pressure and may cause bodily harm such as BURNS to EYES and SKIN!! Loosen or pull the inlet fuel line off and put rag over line. Some fuel injected vehicles have a fuel rail the has a valve that looks like a tire valve. Put a rag over this valve and push it in with a small screw driver and have someone crank motor a couple of times to see if fuel is coming out.

If NO Spark---Could be a lot of things Points (older vehicles) Modules, Coils, Crank Sensors, ECT......

If NO Fuel---- Could be Clogged fuel filter, Fuel Pump, Fuel pump Relay, Fuse, ECT..........

Hope this helps you ??

I have a civic 98 dx manual transmission as driving my car shutoff nd crank it again nd restarted but then after it completely turnoff and wouldn't start again what might be the problem?


Check for spark first from the distributor to the engine: Remove any of the 4 spark plug cable (just one) put it near a propper ground (the inner part of the cable very close to an engine ground) ask a friend to start the engine as he tryes to start you must see sparks jumping from the cable to the engine or chassis ground. (Before you do this, remember to hold the cable with some plastic pliers that way the current won't hit you). If there is spark coming out of the cable the you have ignition and the problem could be that you have fuel issues. To try this, remove the hose that is going to the fuel rail (going in, not the return line), grab an empty coke bottle and put the hose inside the bottle, ask a friend to put ignition switch on, you should see a lot of fuel coming from the hose to the bottle, remove ignition switch and reconnect hose. If there is fuel and spark you have ignition, but in your case one of them will not be present. Hope this helps, if not leave me a message to see what else can we check.

Black smoke comes from exhuast when engine gets hot


black smoke is raw gas burning. a rich condition could be the cause---a bad oxygen sensor, a bad map sensor, a bad fuel pressure regulator, a plugged up air filter, or bad injector. if it was a oil problem then you can smell it. when after running til hot. shut off engine and rub finger around inside of tailpipe to tell! have a good one!!

replace your fuel filter first. If that does not do it, then try an air-flow meter. (if the check engine light is on it may be an airflow meter.
