Re: Stumblin Bumblin Z
 
Do believe I found problem. As I said earlier" I replaced the fuel pumps". Well apparently the secondary pump had left the building first. One night when I went to start the car it would not start. Assuming that the fuel pumps had both died, at the same time?, I replaced both. Last night before pulling the fuel pumps out to check if I had done something wrong installing them I decided to test them with my meter. So, using the method decribed in the "solutions area". I checked the pumps and got only 5.5. I think the secondary pump is either defective or I have a blow fuse. Which gets me down to a new question where is this HUSH PANEL? Don't see it, manual doesn't show it. Please help get this car running right!!!!

I believe the hush panel is the piece of carpeting/panel in the footwell (which would be right above your knees/ankles if you are sitting normally). You may be looking for the fuses under the passenger side hush panel. Note: I have not seen these, just read about them.

Ok, found fuse for secondary pump. It was blown. I replaced with new fuse. Useed the meter again still only got 5.5 amps. Guess will pull pumps out tonight, unless someone else has another idea.

Hey! Just for s--ts and giggles decided to take it for a ride. Well she's back started out a little stumbley. The furher I went the better she got. I assume from not having full power for so long things go gummy. She's running now tho. When I got back used my meter again 10.5. I want to thank everyone for there help.

Glad to see progress. :dancing
You just replaced the fuse? I'd me weary of another failure. If the secondary pump is seizing it will do it again. Most probably once the fuel level gets low enough for it to suck air once.
Just based on the pain of getting in there I'd replace both again.
One of the big no-nos is "testing" a pump outside the tank.
This dry-air testing damages the pump.
They do not just have one failure mode.
They can simply stop
They can fail to hold pressure
They can run at low psi
and worst of all
They can work intermittently :*(

No, I do believe that the secondary pump was already out. Then the primery pump went. At the time I had a SES light so I could get secondaries to come on. Not know that the secondary was blown I replaced both. Never had secondary pump working because of blown fuse.

Good for you!! I know it gets frustrating at times, but usually it is something simple. AND, once you get the car running good, it will be worth all the work.
