Checked everything, spark plugs are new and there are sparks. Fuel pump working, used device that checks for fuel pressure, it passed. Car broke down in traffic, started once after, hasn't started for 2 weeks. Battery seems ok. Radio, indoor car lights working. All ignition lights go off after ignition start. Tried to reset computer by unplugging battery leads, leaving them off for 10 minutes, and reattaching it. No difference. The car is almost about to go....

it starts from cold because the auto choke is on ,allowing a richer mixture ,try removing the sender unit in the tank and seeing if the connection from the pump to the outlet connection is ok or leaking causing a loss of fuel pressure
SOURCE: car (vw passat turbo 2000) shakes on up
its miss fireing could be anything causing it but more likely to be plugs as its doing it under load going up hills plugs is the first place to start
SOURCE: no spark no fuel no start! replaced and checked
funny thing is I have a 2002 GTI with the exact same problem. have spent the last three days at work trying to figure things out.. best of luckn email me if you figure anything out. [email protected]
SOURCE: 1997 Jetta GT 2.0 Stopped running,cranks,will not start
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.
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 ??
