I wired inline fuses to both in and out of the relay box and put in a new ignition.
Checked and bybassed the inertia switch anyway even tho it should be fine.
If i turn the key on the pump will prime for a couple seconds then the 10amp fuse will blow.
So, i know its overloading like Reg said, and that the pump works.
Should i just buy an new pump(100,000+ miles on this one) and check the wiring above the tank and for shorts? Thing that sucks is all the local part stores want $100 for a pump and i cant get one for under $20 off ebay! Guess i have waited this long to fix REALLY fix it so i might as well order one!

The only other circuit path on that relay output is a fuel pump monitoring input which I suppose goes to the ECU. If the load to ground at the #5 pin lead off (connector removed) with the pump disconnected is in the range of a few thousand ohms or more then it is likely the pump is the problem. I you get a pump from a parts house you have the benefit of an instant warranty fulfillment should there be a failure in the alloted warranty period. |

Very true! Im gonna pull the tank and check everything out.
Then get a pump local with a warranty.

I here that John, glad ya told me about it or i woulda been in the same boat. Going to get the $100 pump at PepBoys in a minute. I use a wood board and a floorjack to get em out when their full. then drain the tank while its out, then muscle it back in when its ready. Never really been fun tho. Not even the last one i did when i cut a hole in the bed of the truck to have easy access to the pump. Remember two bolts and a couple lines on the front of the block  ? So much easier to deal with  |

I love my Aeromotive tank and pump. Pop the drain plug and drain from the sump if dropping the tank is necessary. The pump and filters are external, mounted where I can get to them without dropping the tank.  So there ya go, just plumb up an A1000 and sumped tank and this will be much easier in the future. ;D That much closer to a turbo 2.3! |

Its fixed.... Took the tank out cause i couldnt find anything wrong with the wiring anywere! And right there it was! The wiring in the sending unit missing insulation and was shorting out. I guess from rubbing? The ground had done the same.   Went ahead and put in a new Carter pump and a new filter too. |

Glad you got it sorted out. It always ends up being something in a hard to reach place.
