View Full Version : 2.25D won't start - Injector Pump issues?

I have an 82 S3, 2.25D that all of a sudden won't start. Usually she starts right up, but after not running for about a month, when I went to start...nothing. I've read similar threads on this message board, but still can't get it to run. Here is what I have done so far:


Checked gas (have 4+ gals)
Installed new battery
Removed & cleaned fuel filter
Bled Banjo on top of filter
Bled 9mm screw on Fuel injector pump
Removed distributor caps and had someone crank, still no fuel coming out


I've read that it can be a bear to bleed these out. Any ideas for what else to do? I thought about loosening banjo on pump and having someone crank to see if it further bleeds.

Also heard some people say to try and tow start it. Admittedly I have no idea how to do that, and wonder if that will help if the issue is the distributor pump.

Any way to try and isolate what the issue is? I guess it's highly probable that it isn't actually the injector pump, either :)

Most times when my old 2.25D wouldn't start it was either a glow plug problem or air in the lines. Are you running a ballast resistor? Are you getting power to the glow plugs? Some folks run a ballast resistor despite newer type plugs. Another possibility could be the starter. I had a case where it simply wasn't spinning fast enough to start yet sounded as if it was. I swapped starters and it fired right up.
If you're getting fuel AND the glow plugs are hot then I'd check the starter. My two cents.
