Hi everyone.

 

Fabia mk1, 3 cylinder 1.2 AZQ engine.

 

1. From the beginning, the fuel pump was not working. Got a new one. After properly installing, i heard the gas going to injectors.

 

2. Engine was out of timing, so decided to get new chain kit, timing tools for crank and camshafts. Have to wait three weeks for delivery here in Panama.

 

3. As the engine was completely down, changed all 6 exhaust valve bended, sended to a specialist which changed valve guides, etc. Even changed the head gasket.

 

4. Cleaned every single part while engine was in pieces. Bought new sensors, maf, crank, etc. Even cleaned the injectors and tested after and they were spraying like crazy.

 

5. After putting everything back together, with specific repair manual torque, new screws and making sure, no fluid leaks, connections, battery power 11.89 volts. Everything. Found that the fuel is not reaching to the injectors. Not hearing the pump activating at all.

 

6. Fuse 61, fuel is fine. Tested with a test light and current passes. When to see if fuel relay #429, position 4, under the steering not sending the proper voltage to the fuel pump connector. And, according to research electromecanics, this may be a problem. So, with my multimeter tested pin 1 and 4 with the ignition switch opened, and just read 4.11 volts. And to make sure, the relay is working well, i did a resistance test on pins 85 and 86 and chazz. I get no reading at all, which should be between 0.5 to 100 range.

 

For my fortune, in the country where I live, the relay is not available. This is my luck since i bought this car in November 2020. I am not giving up, even if i had many frustrating moments with the F word. Better laught at myself.

 

So, we all these above @sepulchrave@Wino what are the chances that i got a bad relay? 

 

Charge the battery up with a battery charger, or try a different battery that reads more like 12.6V when disconnected. At 11.89V yours has almost no power.

I'm not sure what you mean by the description of the relay resistance test, what's 'chazz'?  The relay coil is between pins marked 85 and 86, so just measure Ohms between those two pins of the relay. 

Check also that the relay socket in the car has 12V at the position into which pin '85' inserts when the ignition is switched on.

I wondered that too; It occurred to me that "chazz" could be a typo for "chaz", which is short for "Charles". But the only reference I could find to a scientific or technical use for Charles was in Charles's Law which is gas dynamics and not electrics.

Maybe he means chassis?

I think he means chassis ground or earth given the context.

I will try to use another battery fully charged, and check for 12 volts in the relay socket.

 

Chazz is a local expression word for failure. Sorry guys. Now, i know it could be used for Charles.

 

I did the resistance ohms on the relay out on pins 85 and 86 and did not mark any. 

 

Will see if the gas pump runs.

 

I'll keep you posted.

 

Thanks

Now I understand. 

 

Use the VW-group part number printed on the relay to search for other cars that may have this type fitted?

1J0906381?

Got it. Ordering now
