Dead Squareback!
My 71 Squareback wouldn't turn over at the side of the road yesterday so I jumpstarted and went home. I went underneath, found a loose selinoid wire and reconnected it. Now the starter turns over but the engine won't go. I have a stock FI system. What could be wrong!

Youmight want to post this question at www.vwtype3.org as there are a lot of stock FI people there. I'm sure they could help you out with your problem, but I think they (just like us) might want a little more info.

I have checked the car and I only hear one click. After letting the car sit overnight it started to fire but then wouldn't work with subsequent tries. Is the cold start device nessecary to start the car or does it only make starting more difficult. If it is completely nessecary then I guess that could be my problem but how would that explain the near starts. The only info I have is the info I have given above, the cars starter stopped working and I had to start the car with hill starts twice. I parked it and the next day crawled underneath to find a disconnected wire on the selinoid. I reconnected the wire and the car would then turn over and fire a few times then cut out. After a few more tries it stopped firing completely, it would just turn over. The next day I gave it another try and it fired a tiny bit then just turned over.
Could it be that the battery is not giving the FI computer enough power?
Thanks in advance,

the cold start circuit has a lead to the solenoid so it only works while the starter is going. maybe it came loose as well? double check that you hear 2 clicks from the relays under the back seat when you turn on your car. Ones teh power to the brain the other is for the fuel pump to prime the system.

My '68 square would not start when I bought it. My fuel pump was bad. I sprayed some brake cleaner into the air intake to get my square started. I just wanted to make sure the engine was good before buying a new fuel pump.

off hand i think you need at least 9.3v for the FI to work.
is the first click right away or after a few secons of turning the ignition switch to the on position. first click is teh power relay second is the fuel.

This is not correct. The starter does not supply the FI system. 71 models...and all FI models get the power for the fuel injection relay (J-16 on the diagrahm) straight from the battery to terminal 30/51 on the relay. Yes the starter may be pulling too much power. The more likely cause is carbonized contacts in the FI relay, a cracked ignition switch with poor contact to the relay, a bad ground for the relay, or just a weak battery. Ray

I am currently working on the car right now and I suspect that the starter is sucking up too much voltage to allow the FI system to work. I believe this is why it can be push started but not started with the starter. Also, the it sort goes for a second on the first start after it sits for a why syptoms fall right into this theory.
The question is: does anybody know how to stop the starter from sucking lots of juice?

Thanks Ray,
I picked up a VOM and found that out too! The relays are fine and the battery and starter are fine. I am now working around on the engine sensors. Could the head or intake temp sensors cause the engine not to start.
Thanks

Yes, quite esaily. The most common no start problems are: (1) the main power to FI at the battery under the seat (2) main ground bundle usually with 3 push-on connectors at the case centerline under the intake plenum (3) the trigger point connector plug on the distributor (3 wire plug) (4) the CHT connector (single wire).
Dirty trigger points can also cause this problem. Ray

Thanks alot everybody who helped out. It turned out to be a bad connection to the fuel pump and had nothing todo with the starter. Thanks.
