I checked the fuel pump and it's not getting power. Checked all the fuse and relays that I know of. I must have shorted something out when I installed it. So, I figure I must have blown a fuse. But I check all of them by pulling each fuse individually in the car's fuse box and the engine compartment fuse box. I'm not sure what to do now. Please help.

Hi,

Okay, let's start with the fuses. There are two that I need you to check. First, check the 7.5-amp ignition fuse located in the instrument panel fuse box on the left side under the dash. In addition, confirm there is power to and from it.

Here is a link that you may find helpful:

If that is good, then check the 20-amp EFI fuse in the under-hood fuse box. Also, confirm there is power to and from it as well.

If they are both good, switch both the EFI and circuit open relays with a different one in the box having the same part number.

Let me know what you find. Also, I attached the fuse/relay schematic below, so you have a reference.

Take care,

Joe
