Can't fire up. Buzzing from the relay, lamps blinkin- HELP

[Red]

"1. Could you say how to jump the check engine conector? "
All you do is place a wire or paper clip in the two sockets to short them out. With the air conditioning switches off, car in neutral, key turned to the "run" position, the check engine light blinks any error codes.

"2. Can you explain how to jump the pump? Is it the 2 pin conector nex to the check engine conector, " I haven't needed to check the pump but I think the procedure is the same, short the pins and the pump is supposed to get power and run. There is a circuit opening relay in between, I'm not sure if this is supposed to engage the relay or bypass it, you'd need to check the manual to be sure.

Of course checking the fuel pump won't answer your first question, which is why you are seeing 10v on the downstream side of the EFI main fuse socket. I don't think you should be seeing any power on that side of the socket when the fuse has been removed.
