the fuel pump works if it has 12v going to it, but i dont have 12v going to it i only have 8.5v. i have 12 coming out of the fuse panel but by the time it gets to the firewall its down to 8.5

is there a fuse or relay or something relating to the fuel pump between the fuse and the firewall?

No offence, but it's getting awfully difficult trying to follow what's going on.

there is a connector...called C203.
edit: Ya. Patrick....pretty hard to follow, but we are getting there![This message has been edited by Gall757 (edited 04-08-2020).]

replaced the pump
as of now i have a new pump (i know works because i straight wired it to the battery since it didnt prime with the key)
a new relay i assume works because i hear it click when i turn the key
i replaced the computer because i was told by several sources that could be the problem
there is 12 volts coming out of the fuse panel but only 8.5 at the firewall
since there is only 8.5v the pump wont work
i cant find any other relays or fuses between
so i am at a loss as to where my voltage is dropping
can anyone think of what im missing?

It's at the firewall, so the orange wire from the fuse box to the connector is damaged or bad pins or something.

so could i run a new wire from the fuse panel thru the firewall and connect it to the harness in the engine compartment that the fuel pump connects to? the only connections i have found are the harness that connects to the fuel pump, from there to the firewall, the one going thru the firewall, and where it goes into the fuse panel. if that is all there is then running a new wire without the extra connections seems like it would do the trick, am i being completely ignorant or will that work?

If it shows 8.5 volts at the connector there is no need to re-wire beyond that point.
