Question about 1991 Volkswagen Passat

1 Answer

Inconsistent fuel pressure

Basically I push on the gas and a little trickles through then it surges and my RPMS shoot through the roof! Vaacum seals are fine as I just replaced them all. It Idles ok has a tendancy to fluctuate after a while but I don;t think this is related as this would most likely be timing? Any thoughts besides mass replacement of Fuel distrib, Pressure reg etc??

Sounds like your fuel pump starting to die. It is not getting enough gas under heavy acceleration which is 100% fuel pump slowly dying. At start up it might not be building up enough fuel pressure to feed the system but the shot of ether and engine cranking helps pressure the system just enough for the fuel pump to trickle the gas and run the engine at low rpms.

Can someone please help me figur out what is wrong with my Envoy? running on 1 or 2 cylinders, irratic idle,light surge, doen't want to stay started, flat on the floor sitting still doesn't go


check the fuel pressure at the fuel rail. you will see a small black cap like you find on a tire. unscrew it and you should see a pin in the middle and the valve will look exactly like the valve on a tire where you put air in. take a small nail or key or something and gently push the pin down while the key is in the on postion.BE CAREFUL AS GAS WILL SHOOT OUT OF THE VALVE!! Make sure you listen close if air comes out with the gas.Keep holding pin down til all air is out and only gas is shooting out. this should solve your problem if not try again and if you have more air in fuel line then you have a leak in fuel line

Check the PCV valve and vacuum lines for leaks. You also need to check the Vacuum advance as it sounds like it might be sticking a little.

5.3 L Missing and Rough Idle Intermittently


i have a 2001 chevy z-71 5.3L. I keep getting a random/multiple misfire code for cylinder 1 . I have replaced plugs, wires, coil pack(only on #1 cylinder)., and fuel pump. I still keep getting the cylinder 1 misfire code. I put truck on a scanner and watched the cylinders. # 1 misfires at idle but quickly stops misfiring at around 1000 rpms. you can here the engine miss at idle but truck runs great on road . anyone else ever had this problem?

1991 vw passat 9A 16v 2l B Charging and instrument cluster problem One day car did not start-turn key and nothing at all.(no power to inst. cluster no turning, nothing) One hour later it did turned on and cranked. and run fine. Next day repeated.Battery was dead.When jumped jumper cable melted.The alternator was shorting. Replaced battery and alternator. But alternator is not charging.Alternator tested as good.Replaced anyway, for another alternator that also tested as good just for the heck of it. Still not charging and whole instrument cluster and radio have no power from the very first replacement repair till now. Car will run just fine with out other el. problems as far the battery have charge above 6-7 v. I checked fuses in fuse/relay panel.Did not see any fuse burned. Is there fusible link on charging system or other fuse or relays to check besides the ones on the fuse/relay panel? I there relay that control this? I know that is grounded good. I know that is connected to + battery good. Alt+battery good. There is small blue wire running from alternator?????? called the alt. control wire. I think is says d+ or something on the alt.terminal next to it. It seems that something prevents the alternator to output power. I measured the alt. terminal + and ground when connected and running and all I read is the battery voltage dropping. I think the blue small wire and instrument cluster are close connection to this problem. Unless there is fuse or relay that I missed to check. other possibilities- ECU. -Wiring harness. First- where is all the fuses? and relays to check? fusible links? second -what is the blue wire ? third-instrument cluster involved? keep in mind that everything works besides inst cluster and charging when battery have charge above 6-7v. This car have disconnected and missing ABS and Security . Run grate for about a year till this happened. Rebuilded engine....Clean well maintained.. u4davidatgmaildotcom
