i finally got my truck fixed and it ran great. i drove it about 350 miles no problems at all... till today. i fired it up and i ran perfect. i shut it off to get fuel and when i went to start it back up it didnt even fire. i cracked my injectors several times to make sure there was no air in the system but i still could not get it to fire at all. no idea what to even think. it seems to be getting plenty of fuel

 

Have you checked the shut off solenoid?

 

how do i check it. would i still be getting fuel to the injectors if it was not working

 

I replied in your other thread as well. To check it, put 12V to it, and see if it clicks, if not it is probably bad.

If it is bad you can gut it, and use the shut down lever on the side of the VE or install a pull cable to shut it off. Or you can buy a VW one for around $10.

Just curious, but is your pump turned up? The main reason for solenoid failures in our trucks is a cranked pump with stock injectors.

 

yea the pump is cranked with stock injectors. i guess is should turn it back down till i get injectors then.

 

has the pump ever been rebuilt???? are you getting fuel to the injectors????

 

You do get fuel to the injectors with the shut-down solenoid closed. I don't know how that works exactly, but I have seen it several times. It won't run, but it will shoot fuel. I think that the solenoid is designed to flow a minute quantity at all times for lubrication purposes.

Remove the solenoid (24 mm wrench, requires removal or modification of the steel backing plate on the back if the pump head), and the little plunger should just pop out. Reinstall without the plunger and see if it works. If it does, you will need to use to lever on the side of the pump to shut it off.

Something could be wrong in the pump; broken return spring. If it was a new pump, maybe you got a defective part. Or built wrong.

Otherwise, to ensure that it's totally primed, you can always resort to unplugging the grid heaters and shooting the ether.

 

i replaced the solenoid and that was the problem. thanks for the help
