Need help with my 89 turbo no power to fuel pump
Here’s the scenario, I was about 200 miles from home when I started blowing the fuel pump fuse at the under hood fuse block. As I was driving it kept blowing the 15 amp fuse, so I went to a 30 amp to try to make it home (I know that using a bigger fuse is bad but I needed to get home. So I had the wiring harness rebuilt and got most back together, but no power to fuel pump. Looking for ideas to repair it. What is the next part that can make it lose power to fuel pump

To clarify, by running the 30amp fuse you damaged the wiring and had the wiring redone? I would continue to look at that as the first step.
I believe the fuel pump doesn't come on with the ignition (i.e. turn the key and hear the pump run - I wish it did). It starts as the engine starts (someone can correct me if that is wrong). Can you straight wire the pump (direct from the battery) and hear it run? That will tell you if the pump is even good. It could be the pump is bad and drawing more power than it should in order to run, hence killing your fuses. |
It wasn’t the 30 amp fuse that fried the wiring harness. The short in the wiring harness was why I had to use 30 amp fuse. When I put power to the fuel pump it worked. The fuel pump does kick on when the key is in the on position. I’m hoping to find someone who can tell me what Parts could be failing. I’m thinking a fusible link. Does the fuel pump wiring go through the ECU? Maybe I fried the ECU? Thanks for your help
