Re: 87 vw will not start
Sounds like the fuel cut off relay. i can remember the number but i think the relay is longer than the others. their contacts go bad and operates intermittently before they die. you can try prying the relay open and clean the contacts, but its better to get a new one and keep it as spare in glove box. i think there are two relays related to fuel, but like i said, this one is maybe a longer(higher) than usual size.

what happens if the lights are on and he attempts to start? do lights dim or is there no change? If lights dim the ignition is making contact but the starter is not engaging ! If lights do not dim then the ignition is not making contact. start at the starter and check for ignition wire contact. a small 12 - 14 gauge wire. try to cross terminals on the selonoid and see if car will turn over, ( starter engage ) if it does then one of two things, selonoid is bad , or the ign wire is bad, some have a fusable link in-line check for one. you can check the ign wire by using a test light, ground to a good ground and while a helper turns key to start position test wire for power (test light lights ) if there is power then selonoid is most likely to be the culprit.Be sure to support car on jack stands or use two floor jacks or one floor jack and one bottle jack !!!! for safety reasons, of course if only one jack is used and it fails the possibilities of death is 98%, the possibilities of serious injury 100%. also keep fingers clear of all moving object in case something does engage causing movement.
sounds like a bad idle control sensor, most garages charge $75.00 for a diagnostic, the sensor is about $45.00 it could also be a bad fuel filter,have you been burning 87 octane fuel?[cheapest fuel] ethanol fuel is'nt good for your v.w. at least try to use 89 0ctane but no ethanol fuel!! you can use 87 octaneBUT you need to add octane booster with it, which you can get at the dollar general,wal-mart,k-mart,auto zone,advance auto it's really an economy thing though. what ever your budget is, i have a 87 toyota van and use it every day for qa mechanic svc. i buy 89 octane fuel,i've bought 87 octane and everytime i have,i've had to replace the fuel filter. merry christmas!! and as always, if you need further assistance please repost your question and an expert will be happy to assist you!!
Possibly air in the fuel lines. Possibly Fuel Injection Pump Case Relief Valve has come apart (funny looking ,10mm bolt with 2 round sides on left side of Injection Pump). Great site for TDIs - www.tdiclub.com - forum thread on this very problem. Great people will help get you going.
first check the ignition switch. then Check all of the battery terminals and cables and check the wires on the starter/selonoid, start from the battery and follow the cable out and check all conections , clean and tighten them and if it still does it the starter/selonoid is bad and needs replacement...
