Fuel pump open circuit relay question

I missed that one.
Thanks man.

I’m trying to help my mother find a place to rent while they rebuild her house after a tree fell through it. Then salvaging what I can from the house between rains.
So I’ve been busy, I need to slow down and actually look what’s right in front of my face. Lol

 

I appreciate all your help immensely thank you!! Ok yes power to one pin has changed. Originally when I pulled the FPOC relay it had power to #2 and I jumped that to each of the other pins one at a time and nothing happened till I jumped to #4 I THINK and it blew efi fuse. I just checked c6 plug and no power to any pins ignition on and off no difference.

 

I have 2 OBDII scanners and both say unable to communicate so I havent been able to pull any codes. Is there another way? Also what is vehicle EWD? I'm pretty mechanically inclined actually but when it comes to electronics I'm illiterate. Diagrams just dont make alot of sense but I'm constantly trying to learn.

 

The #2 pin is powered by the EFI relay.
The EFI relay is powered by the EFI fuse.
Check EFI fuse. If good, pull EFI relay and check Pin # 3 of EFI Relay.

 

When you turn the key ON. Does the check Engine Light come on?
It should for a few seconds.

 

Check pin 3 of efi relay. Why dont I know which pin is 3?? Watch to see if check engine light comes on when key turned on. Got it. Except pin 3

 

No check engine light at all. Battery, oil, brake, blank space, and air bag are the only ones lighting up on the dash.

 

Unless you missed a open fuse some place.

Quite possible your mishap applied voltage to the ECM directly which is now in need of some love depending just how bad it was fried !!

What happened was all the circuit protection may have been bypassed.

Good luck!!

 

So what does that mean need some love?

 

You have a blown fuse most likely. Either 7.5 IGN or 15 EFI is blown

 

As in tender loving care .

It needs attention !! perhaps it can be rebuilt you might be able to find a used one to match what you have.

after you have eliminated all the other areas that might be open causing the ECM to no longer work.

 

I wanna say PIN #1 is hot

 

Drabt100 IGN15 is the upper one in the dash fuse panel correc? It's good along with the EFI15 under the hood

 

IGN should be a 7.5 amp fuse in the passenger compartment fuse panel. I do not know the location in that panel. Should be a sticker on the inside of the panel cover showing the fuses and what they are for

 

My 99 has a fuse panel on the left below the clutch bypass button

 

Ok you should have 12 volts at terminals 1 and 5 of the EFI relay connector with the relay removed, key in the on position.

 

The EFI relay under the hood correct? Not the fuel pump open circuit relay.

 

I only have 12v tp pin 1

 

15 amp EFI fuse powers terminal 5 and the ECU. Check it again
