Question about 2001 Volkswagen Cabrio

2 Answers

2001 cabrio. Injectors won't work. Is it the computer? I have fuel and spark

I've had an intermittent starting problem for some time. New coil, wires, air mass. coolant sensor, fuel filter, fuel pump relay. If I do get it to start, sometimes it runs for a day. Some times it dies as soon as I give it gas. Want to buy a car?

Here is an out of the box thought!!!


An "intermittent" happened to me once on a long distance trip in a 2000 Cabrio convertible - - several ocassions (especially during humid or rainy weather.) The car left me stranded out of the blue. Would not start even though it was running fine minutes earlier. After a few prayers I stumbled across a cracked and loosely mounted hose - - - The quick fix was taping the hose coming out of the firewall into the engine. I eventually replaced the hose after the long trek. The tape worked great but once the hose popped off the connector. The symptom started again so I cut the hose and secured the connection. No more problems. I suggest checking all the vacuum hoses and such for looseness, cracks or breaks. They may be affecting the ratios or sensors. If this doesnt help you then I hope it helps someone else. The spur of the moment fix saved me a bucket full of money, so may a similar blessing happen to you before you have to pull more cash from your pocket.

First off, is it diesel, or gas? Does it start better when warm? Volkswagens ( I've owned 5) are notorious for electrical problems ( starting relays/injector plug relays). You didn't say that you replaced the fuel injectors, (on diesels they are quite expensive, but can be rebuilt if they prove to be defective). Have you had anyone check it on their computer?( if you changed your timing belt, your injector pump on the diesel could be badly out of time). Fuel hoses / clamps also tend to leak and allow air into the system ( fuel filter/ fuel tank pump on gasoline) which is almost the kiss of death for diesels ( they seem to be very adverse to air bubbles in the injection pump). Your solenoid shutoff switch on the fuel pump may also be sticking ( mine wouldn't allow the engine on my diesel to shut off, had to stall it in gear). Lots of things to check, do you have a "Bentley" factory manual ( I know they are expensive, but so are shop charges).

Checking for spark is really simple while fuel delivery is more complicated because of the the way it is metered for delivery. On VW's a fuel pump relay is used and a jumper cable connected to relay box. This controls the fuel pump to deliver fuel manually. With a fuel pressure gauge connected to the line from the pump continued withing the system, you assess whether you have correct fuel pressure, maintain it within a specif duration. Electronic fuel injectors do stick or stay open causing very poor or no start condition. Make sure you have fuel delivery since you are positive that spark is present.

Fuel pump


Testing of the fuel and ignition systems is in order. Intermittent problems need testing when the problem is present, otherwise it won't help find the problem.
I would start by checking for spark on a spark plug wire (or two or three plug wires, in case it may be a bad coil), during those times when it won't start. You need to see a blue, snapping spark to verify ignition system is working.
To check the fuel system, have the fuel pressure checked, and the injector circuit checked. Good that you hear the pump, but you don't know if fuel pressure is correct, or if fuel is getting into the cylinders. One short test is to spray starting fluid or carb cleaner into the intake while engine is cranking. If engine fires up for a few seconds, you know it is a gas related problem.
If ignition system is the intermittent problem, could be failing coil or coils, ignition module, crank position sensor, even the computer, or a wiring problem like a bad connection. Testing of each component will be required, or you could start throwing new parts at it, like many people do, until you find the bad part. Find a reputable mechanic-there still are a few, lol.

My 2001 f-250 won't run the fuel pump kicks on and continues to run removed the plugs on injectors one at a time and still does same thing could it be the computer



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: -----

Van started to run rough, then shut off. Will not start. Replaced fuel pump and crankshaft sensor. Tested coil spark - good. Tested plug wire spark - good. What is next?


You need to know if you have fuel pressure at the injectors and if the injectors are opening. I would check for voltage at the injectors and a ground signal from the PCM after checking for fuel pressure.

My 2005 dodge neon sxt wont start, no spark, changed cam shaft sensor, coil is good, cant find the crankshaft sensor, also wondered if it could be the timing belt, what do you think?


the crank sensor is on the back side of the engine just above the oil pan there will be two sensors there one is the crank sensor and the other is oil presser sensor. All so check the wires from the crank sensor to the cam sensor. If you think it is the timing belt pull the cover and check it. hope this helps.

1997 Saab 900 SE Turbo. Problem repeats. Car is off the road. Had started up just fine, several days in a row, now it turns over just fine but does not start. Can hear the fuel pump pressurize. HAd done...


start with the basics: an engine with no internal problems (like timing belt broke, or valve train not timed) needs fuel and spark to start.Since your getting fuel up to the fuel rail to feed the injectors, lets assume for the moment that the injectors are working to put gas into the cyllinder (You coud check that by pulling a plug or two out and see if they are wet or smell of gas.) Then check for spark (Hold the metal tip of plug wire 1/4 inch from a metal bolt or ground on the engine. Careful you don't get a shock-you can also buy a spark checker for a few bucks. just put the plug wire on it and ground it with the clip. Then you won't get a shock.) If you see that it is getting spark, then you may need an expert diagnosis for why it won't run. If you do not detect any spark (might want to try more than one plug wire) then you need to diagnose your ignition. If your car has a distributor, take off the cap and check inside for a cracked dist. cap or bad or worn rotor. You may also have a bad ignition coil or ignition module (expensive, but not as expensive as a bad engine control computer. Distributorless ignition? Again, may be a bad coil, coil pack, or ignition module. good luck, i'm about out of suggestions.

My 2001 GMC Safari has been running rough for a couple weeks now.. I've replaced spark plugs, spark plugs wires, coil, radiator, cap and rotor and checked the egr valve, check the maf sensor. Nothing...


Look and make sure your computer is good! PCM could be failing you! Injectors don't really go bad! Also look at you fuel pressure make sure it's strong!

1992 bronco crank no start


are the injectors delivering fuel? just because u have fuel press it doesn't mean the injectors are working, buy a tool called a "noid", about $5.00, it plugs into the injector connector and blinks when u crank the engine if the injectors are working, u do one at a time. if not check the wiring harness to the engine, very common to have problems there. I have been a Ford dealer tech for 20 years and my specility is this type of problem, i.e. no starts, the ECM/PCM is not a common failure.
