Some of you might have read my posts about thinking I had timing problems on my new 1.9 in my '85 Vanagon. Upon furthur sleuthing, cyl 1 and 3 seem to not get any gas. If I pull the connectors going to either 1 or 3 FUEL INJECTORS when the motor is running, it keeps on going, If I do that to either 1 or 4, it dies ! I've troubleshot as per the Digijet F.I. manual, metering on the ECU multi- pin connector, and all my injectors measure out to 18 ohms as per spec. However, what is REALLY odd is that the book states the following for the respective terminals to the ECU: 11 & 7 to cyl 2 Mine meters to cyl 4 12 & 7 to cyl 1 Mine meters to cyl 3 23 & 7 to cyl 4 Mine meters to cyl 1 24 & 7 to cyl 2 Mine meters to cyl 2 And what is odd is that you cannot mistake the injector wires and their bundle to cyl 1 & 2 because they are longer and have to go ACROSS the engine. The respective wires to cyl 3 & 4 are only like 8" or so from the main cable bundle to the ecu !! I am getting spark to ALL 4 cyl. If I disconnect either plug 2 or 4 when the motor is running (Yes, your 1.9 WILL run on 1 cyl !) you can definatly smell the unburned gas in the exhaust and on the plug. If I do the same for plugs 1 and 3, nothing, no gas smell, nothing. Also plugs 1 and 3 are clean, out of the box clean, 2 & 4 are showing use. What's up ??? Frustrated in Memphis !!!!
