If the part numbers are the same they should have the same high amperage rating . Item # 1 / LJA6703AA
supperceded by C2P11192 . Air Conditioning relay is the same . You only have # 1 fuel pump on non - supercharged engine .

You can take 2 blade connectors and place them in the 2 larger relay sockets to power the pump as this would bypass the relay control side of the circuit and get you full power to the pump . High current arcing hazard so have battery terminal removed while placing jumper in sockets .
There are 2 fuses in the single pump setup like yours one for the main power and one for relay control
Can you elaborate on your pump issue as the pump is controlled by the ECU by the Crankshaft sensor seeing engine rotation to turn it back on a second time during the starting sequence . This is a safety / crash design feature . The Crankshaft sensor my be intermittent and not flagging a code .

I pulled the pump, after 5 hours of trying to reach the lines. When installing the new pump I noticed that the connect at the pump is damaged/falling apart. Then I looked close at the pump I pulled and noticed what appears to be a burnt spot on the + connector. Looking for a wire pigtail now.

Vern reading here ref the possible fuel relay failing. Where is this located. Front fuse box or rear ?...built in or something easily replaced ie not built in ?
Most grateful for your help
