Since he provided this for context:

Engine I swapped in ran when pulled  from another car a lot of years ago but was tired.

And he already replace the front seal.

I would put my dime on the vanes being stuck as well.  They do that if they sit for a few months. 

You might have luck with some Diesel Purge and not have to pull the pump apart.

Any time I have had a problem like this, it was always remedied by replacing the front seal in the fuel pump (the seal on the input shaft). The front seal allows loss of pump fuel prime.

No, I am not going to debate you saying you have fuel at the pump, etc. I always did, too. But, it is not enough pressure to actually fire the injectors.

Every time, as soon as I replaced the front seal.....problem solved. Eventually, ALL of my pumps were wearing new seals and I was never standing still. End of story.

You filled the fuel filter and pump entirely with fuel before trying, right? My favorite way is to pull a vacuum on the return fitting.  With clear supply and return lines do you see fuel move at all?  It should move regardless of stop solenoid activation/function.  If it is not moving fuel when cranking, then the vane pump vanes are stuck or the pressure regulator is stuck flowing all fuel back to the supply.  Smart money would be on the vanes being stuck.

Good thought but there's power and I hear a click at the pump when rhe key is turned on.

May seem like a stupid question but do you have 12v to the shut off solenoid?

IDI Engine / AAZ won't pump fuel...
« Last post by Patrick on Today at 05:56:02 am »
Haven't posted in a long time. Swapped an AAZ into a 92 Jetta this weekend, pulled out an AAZ that's getting tired (low compression). Engine I swapped in ran when pulled  from another car a lot of years ago but was tired. Had a start issue that I traced to the input seal on thr pump, kept losing it's prime. new seal, went through the whole engine. Rings, bearings, head studs (plans for the future), water pump etc. Been on the shelf for a lot of years. Finally put it in the car this weekend. No luck getting the injection pump to move fuel. Currently sitting overnight with fuel/ATF mix in the filter and the pump. I'm assuming the vane pump is stuck from sitting around.... Anyone got any suggestions?

Need to replace the entire cold start cable to get IP to work well again.  Need both inside and outside cable parts.

Speedometer is not giving proper speed or mileage.  Need a need just a functional speedo but complete cluster is good too.


Send a PM and I will get back to you.  On here most evenings.

Thank ums
