just when I think I can fix something!

[genova]

1. I drained my fuel tank

2. Added a (FI) filter after the tank and before the FP used new F.I. rated fuel line

3.Took the cap off (BA fuel pump)and looked for any yuck (none found) put back the seals and spinner put the cap back on tighten the bolts.

4.Changed the fuel filter

5. changed the pressure regulator.

made sure everything was tight and sealed.

Now I can not get the car to start it turns over but nothing tried to cough (almost start) a couple times at first but not since and yes I put gas in the tank about 2 gallons.

The only thing I can think of is that I did not put the fuel pump back together correctly but it looked like it only went together one way.

Do I have to prime the pump? Do fuel systems get air lock?

I read someone say that you have to fill the tank all the way to get it to prime. Don't want to do that and have to drain the gas to get back at the FP.

Need some help:sick:

If you drained your tank to empty it takes 3 gallons of gas to even come close to start trust me I went through this to. Put in 4 gallons. It will take a minute to let the pump prime.

That is music to my ears! I am going to try now.

[genova]

OK here is what I am thinking.

I know that I could get it to idle all day if I wanted before I touched anything.

So I know I had power to the pump. I know the pumped worked.

now comes the lesson for me.

since the last time I have:

1. Added more gas (about 5 gallons in the tank now).

2. Taken the outlet house from the FF (under the hood) at the rail and hung the end it into an empty anti-freeze container and turned the key nothing just a drip (probably left over).

3. I unhooked the inlet house to the FP removed the pump took the head off (my pump looks like the one in this link

(http://atlanticz.ca/zclub/techtips/fuelpump/index.html)

its the one with impellers at the bottom.

everything looks good seals and such. get the head on nice and tight.

4. Slowly fill the pump with gas by pouring it in the intake opening until she is full.

5. Get gas moving thru the added filter in the rear and flowing out the house.

6. Re hook up the fuel pump.

7. Nothing, still will not start.

8. Getting no sound from the FP when the key is turned to start. (:bulb:realized I was killing my battery so I disconnected my starter to lessen the energy draw due to all the cranking over).

9. I do not have a meter to check for power at the fuel pump terminals at this time but I will when I buy one later.

I took a picture of the wire and how they hooked up to the FP before i touched anything and I have put them back exactly as they were.

So....

IF I find I have power(which I anticipate I will) Did I somehow break the FP?

1.If I did is it spent?

2.What could I have done to it?

I thought my FP had a screen inside the cap Like the first one in that previous link but it did not. Had I known it did not I would of never got into it in the first place :stupid:

Any thoughts my fellow Zed's?

1) Verify the FP relay and fuse!

2) Verify the fuel pump is good by running straight from the battery. then verify the fuse!

Verify the FPR is working.

3) Disconnect the inlet fro m the fuel pump-gas should pour out of the hose if everything is primed. If not...apply air pressure to the hose(not with your mouth!) and listen to see if bubbles are heard. If not your inlet is blocked-apply more air pressure, or take wire and attempt to clear the line with that.

4) If there is a check valve in what you removed and replaced, be sure you oriented it properly.

Will

There is a check valve in the system be sure it isn't in backwards

[genova]

ok I will try that HLS30. I also have a multi meter now and am going to check for power at the FP tonight. I am going to have to look in the FSM to find where the FPR is. You said verify the fuse? What fuse and where? I looked under the passenger dash at the fuse box and did not see any blown but I also did not see any marked for the Fuel system either.

Thanks for the direction I will update tonight.

Have you down loaded this yet? EFI Bible

[genova]

Yes I have the bible, I could never have gotten this far with out it. Thanks for the link anyhow. I did not get a chance to work on the car last night nothing to update. I am going to put the multi-meter on the FP tonight. I am not sure if I want to find power back there or not? New FP or new FP relay what a choice :-)

You have the bible but do you have a 1976 FSM?

The bible is more oriented to a 75 and there were some changes made by 76.

I have the FSM for a 76 & the Fuel Inj. Bible down loaded off of the blue site.

I know everything is hooked up correctly.

The one thing that haunts me is that I put in a after the Fuel tank filter on the advice of some on here. They recommended the Fram G3. The nipple or outlet on my fuel tank is almost .5" how can you fit a Fram G3 and hose on to that? Is there some adapter? or do you just pull super stretch? I would rather have a see thru filter but can not find one that fits the tank. I have a G3 and the hose to install it. I am going to be under there this weekend and I can change it out if someone can tell me how to make it fit?:nervous:

Any takers?

Fuel pump issue has been fixed! Thanks for all the help everyone:classic:
