Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose).
Do you still need help, if so let me know and I will try to help. This is not an answer.
Did I read correct, you have power to the read wire at the pump and ground on the black wire with the key on but you have no fuel pressure to the engine. If that is the case then the next repair will be replacing the pump. Let me know if I understood wrong?
At the coils are you getting ground on the black wire and with the key on power at the white wire?
Using a scan tool is the computer getting a crank sensor signal?
If you're confused on what to do now. You have already been charged the full question value. It's now time to compensate the tech that helped you. The only way I can continue to work here and help customers is by getting rated. If you're not pleased yet or plan not to rate me. Let me know so I can help more, close the post, or opt out.

Thanks, ***** ***** need to do some electrical tests at the pump relays. Here are the diagrams. https://dl.dropboxusercontent.com/u/90220402/lancerpump.pdf
Remove pump relay 1, are there 2 power pins there? If so install the relay and do the same test at removed pump relay 2?
Did you install relay 1 then check relay 2?
Relay 2 gets one of its powers from relay 1. Relay 1 and 2 get one of there powers from the same fuse. So its relay one that is not energizing since it is getting 2 powers. Remove relay 1, there are 2 powered pins there. There should also be a pin with no power or ground and a pin that has continuity to ground. If you get that result then replace this relay.
Sorry you feel my diag assistance is basic. What are your needing so I can provide that?
