Where is the starter enable relay located?

The Starter Relay is located behind the DIC (Driver Information Center) Panel.

Will ECM cause fuel pump to not work?

There also will be an electrical connection, this is usually in the ecm engine computer. If you do obtain this reading and the ecm will not make the fuel pump operate, replace the pump. If you do not obtain the correct voltage, the problem is somewhere between the fuel pump electrical connection and the ecm.

What causes relay failure?

In fact, the life of a relay is essentially determined by the life of its contacts. Degradation of contacts is caused from high in-rush currents, high- sustained currents, and from high voltage spikes. Relays can also fail due to poor contact alignment and open coils.

How do you damage a relay?

Switching an inductive load. The biggest “enemy” of a common relay is an inductive load, such as a solenoid or an electromagnet. Its behavior is the most damaging, capable of completely destroying (welding or burning) the relay contacts. It behaves in the opposite way compared to a capacitive load.

Do solid state relays go bad?

Under normal service conditions, SSRs seldom fail. But when they do, they nearly always fail shorted. The user might not realize that the relay has failed, depending on the load being controlled—or no longer being controlled.

What happens when a solid state relay fails?

One disadvantage of solid state relays is their tendency to fail “shorted” on their outputs, while electromechanical relay contacts tend to fail “open.” In either case, it is possible for a relay to fail in the other mode, but these are the most common failures.

How long do solid state relays last?

They have an infinite lifespan. Again, without the presence of movable contacts, there are no parts to be worn out and carbon doesn’t build up. An EMR has an average lifespan of one million cycles, whereas an SSR has a lifespan of roughly 100 times that.
