Christopher J. Valade , I wrote some EFI procedures before, looke in the forum archives but hear goes some info from the top of my head. The problem of not starting can be caused by a number of problems. You say this car is a 1970 with EFI and it stopped working when the foot was taken off the accelerator ? or was it the clutch pedal ? Sudden lunging may get some old wires in the harness to disconnect or break. old wiring harnesses do that and boy did I have your problem before, I changed coils and plug wires to no avail . After I fixed my wiring , the problem never came back. I had to first make sure the engine got it's spark and was statically timed right (timing adjusted with engine off), then I made sure the pump worked by having someone turn the key all the way on and off while I was phyiscally feeling the pumped for detectable vbration or movement which could indicate power is getting to it or it works, when no movement or sound was detected I bypassed the two wires with my own hooked up directly to the battery and the other to the car's body/chassis, still no movent then pump is bad . With a good pump, relay and wiring, the pump should only move for a couple of seconds without actually turning the engine, that is when the key is in the 'on' position with the oil and gen light on and when you crank the engine and engine starts then the pump would keep going continually. This controlled by the computer. Next I fixed the cold start injector that was always on and kept flooding the engine, it would not start in this condition and the engine would stop turning since the cylinders were filled with gas. I found this by removing my spark plugs, they were always wet. The injector was leaking greatly and it was hooked up improperly, one side + hot should be hooked up to the starter solenoid where the key 'crank' power comes in and the other to the cold start injector temp sensor, mine was hooked up to the engine case and always injected even when hot. On the "C" brain (numbers on it with a "C". I think the 1970 injection system had a fuel enrichment system similar to the carburator squirt pump but electronic. With the key in the 'on' position you can hear a series of 20 squirts or clicks comming from the injectors everytime you step on the foot pedal all the way down, it would be easier if you did pump the lever manually at the intake so you can feel and hear the injectos two injectors should only inject at any given engine position and should always be on opposite ends diagonally. You can prove the injectors are squirting by removing them with a little 10mm socket and a 1/4 in rachet. Without unplugging them put a pair in a coffee can or jar and see if one squirts when you 'pump' but remember to remove the wires from the coil, you do not want any fires. After verifying that one works, turn the engine a little maybe from 1/2 to 3/4 turn, the other should squirt when the accelerator is pumped. Do the same to the otherside. If no squirt is detected then look at the wires and connectors that go to the injector, if no injector is working eventhough the ignition is on and you are pumping, then check the injector points and connections below the distributor. If that is all good, you may not have fuel pressure in your lines, I would hook up a metal pressure gauge to the hose the cold start injector uses . I used a gauge I bought at a hardware store or a industrial surplus store for about 5 bucks and added a hose nipple from and autoparts store hooked up the gauge (0 to 60 lbs range) to the Cold start injector hose and found I had no pressure, I found that one of my injectors was stuck open and made the pressure go down in seconds, I found this when I had both set of injectors in jars and place the key in the 'on' position and off position several times. The procedure above will only work if you have a "C" brain on all others you must crank engine. Lets say all of this is good then you may have a wiring problem, check the wiring , especially the head temp sensor connection , it is very fragile, check out the Pressure sensor connections. Make sure your fuel pressure is adjusted to 28 lbs. Most likely , you may have a loose wire so check the schematic diagrams for the system in the Bently VW manual. Maybe somone from the list can help you ? Where are you located ?
