Note: I did have a check valve problem with one new Airtex, but was able to exchange it for one that was good (at AutoZone). I don't mean to cast dispersions on Airtex, but rather to suggest blowing air (used my mouth) on the outlet tube to see if check valve was operating before installing the pumps. Just a thought. P.

Re: Help!
Is there 0 resistance from the plugs ground to the sender unit base. Could of lost ground which would make both not work, I agree seems odd both pumps would fail.
If there's good ground connection can you connect you VOM red lead to the grey or grn/wht and ground the other lead to the pin in the plug at the same time your applying power from the alternate power source to verify power is getting there.

Re: Help!
It looks the same as the one I put on my primary, the area of it was close to the original. The secondary original strainer on mine is twice as big though and wraps upward. But I don't know what other choice you would have, unless the dealer still has them. But I don't think I would worry about it.
If your want to do some R@D.....install them on both and check that fuel pressure at WOT doesn't fall off.

Re: Help!
Does yours have the flat gasket at the sender unit, or big O'rings? Mine has the flat rectangle gasket and had to get it at the dealer, $22.

How would I check the ground at the pumps without having to pull the pumps. Either way it looks like I need to pull the pumps. I ran a direct ground from the battery to the black wire going into the tank I then ran a jumper to the green and then the grey. still nothing. I am going to buy the pumps and strainers right now before the parts houses close for the day. Any input would be greatly appreciated. Dave |

As for both pumps going out at the same time, that would be unusual, at the least. More likely the secondary pump failed sometime before and was never detected until the primary pump failed...would be my guess. P.

This could help verify a bad pump, my pumps had 5 or 6 ohms of resistance when removed, and the bad pump was "open". Do you see any sparks when you connect the jumper wire to run the pumps, should be a visible one....and be careful for GS

Re: Help!
Good luck, sounds close to a fix, could only be the short runs of wire in the sender, or pumps.
You might be able to reuse the sender gasket if the pump kit doesn't have one. Mine was too old though.
