When starting my van the lights come on but nothing happens, it is totally dead......battery is ok ..... pop under the driverside rear wheelarch and check the signal wire to the startermotor is connected to the spade connector on the solenoid.
1. Turn key to first position- red dash lights not coming on. Battery flat or electrical connection fuulty, i.e. battery leads loose or fuse loose/blown
2. Turn key to second position (start)- no "click" and starter not turning over, see 1, and starter motor seized or electrical connection to starter motor loose. If connections are secure and not to corroded give starter motor a couple of hits with hammer or similar to "unstick" it. suspect worn starter motor bush. [All engine faults/repairs/maintenance Replace starter motor|maintenance Replace starter]
Check the battery connections. They need to be clean and tight otherwise the voltage drop will be so high that the starter motor won't have enogh current to turn.
not enough volts at starter- check cables and connectors at batttery and motor.
check signal from ignition key -check for 12 volts from the plug that pulls off the back of the solenoid when the key is in first position, otherwise dodgy ignition broken wire etc...
motor worn-check by jumping from the fat battery cable on the solenoid to the push on connector (see picture below). Starter should whir into life otherwise suspect motor. MAKE SURE VAN IS OUT OF GEAR!
If motor whirs under above test, suspect dodgy bush.
yeah, give it a whack with a hammer while someone is turning the key (MAKE SURE THE VAN ISNT IN REVERSE THOUGH) !!!! if it turns over then, scrap it, someone will have one in "classifieds" or GSF (GSF PRICE £68.50 exchange)
From |The Brickyard
All petrol models. Poor starting. (Not diesels) Engine turns over slowly, if you don't catch it first time you've got no chance of starting it today. Battery, alternator and wiring all checks out good. Worn started bush. For some reason VW decided to have the starter motors with only one end of the armature located in a bearing, the other end is located in a bush in the bell housing. The bushes wear and disintegrate, this lets the armature of the motor cock over, stator now touches armature, excess friction hey presto one slow turning engine. Remedy is to fit new starter bush, trouble is they are a bit of a pain to do. On the good side they cost about 1GBP2004! Remove starter, pick out old bush with a screw driver, if its stuck fast use an expanding masonry bolt to grab it and pull it out (internal diameter of new bush is 12mm). Press new bush into place. Note that these bushes are not phosphor bronze but something with a posh name! they need to be left to soak in engine oil for 24 hours prior to fitment to prime them.
