2007 VW Transporter Fuel System   

As I took off batt to fix back lites,when batt was placed back,I tryed to start as I do and car will only startm with a little start fluid, but will no get fuel to keep it going. I checked pump, and it is working sending fuel to injectors but they seem not to be opening, is there a sensor that opens them up? Please advice wherethis apparatus is.Thanks

It's a 1978 transporter, not a 2007

It is a 1978 vw transporter

Hello, The 1978 has either a Fuel Pump Relay or a Double Relay that appears to be hot at all times.

One side of this computer controlled relay powers the fuel pump and the other side of this relay powers the fuel injectors.

With the key on do you have power at the injectors?

Roger

No I have no power to injectors, only thing that works is the pump Following the fuel from the pump, the fuel ends at an injector, I see some small plastic part at the entrance of this injector,and there are a couple of wires, I dont know if they are suppose to open this injector or what?I have tried anither control unit thinking it was bad but it did the same.

Power for the injectors comes from the relay I described to you. Have you located this relay? If it is bad that could be the trouble.

Roger

I will check the relay like you said,I belive I 'am not getting any powerfor I have checked with andc meter each of the wires at the entranceof injectors, I plan to do this tomorrow monday, can you tel me if the power comes from one of the leads of the coil?

Power for the injectors comes from the relay I described to you.

The coil is powered by a fuse.

I asked before thinking the reson it will not start was injectors did not open, the double relay was given as answer, aia bought a d-relay, it still willnot start, it starts with startig fluid till it lasts fo an instant.fuel pump working gas at injectors, I still don't know if they are open, but its a new relay, let me know some more.

The first thing you need to do is check to see what you are missing at the injector, power or ground? With the key On and one end of test light or voltmeter to a known good ground, check for power to the fuel injector electrical connector... do you have power?
