I have actually purchased a brand-new fuel pump and it is still got no strength to it. My partner looked under the bonnet and under the steering wheel and cannot find a relay. I have no idea what come do, any type of suggestions would be appreciated.
Welcome to rememberingsomer.com.The relay/fuse crate is under the dash top top the left side of the vehicle. There space two fuel pump relays. Ns attached a couple of pictures to assist you locate them.Under the hood, examine fuse 8 in the fuse box. See last picture.Let me recognize if this helps.Joe

The most common mistake is expecting to find 12 volts at the fuel pump once just turning on the ignition switch. The an initial thing to do is try to hear for the hum of the pump for just one second when you revolve on the ignition switch. Sometimes that is difficult to perform with the chime make noise.The following thing is to examine for spark when a helper cranks the engine. Defective fuel pump circuits cause the crank/no-start difficulty only about five percent that the time. A loss of fuel pump and spark causes closer come 95 percent of these failures, but most people get grounding on the very first thing lock find absent and forget to look for various other things that space dead.If you have no spark, this conversation will have to go in a various direction. If you never ever hear the hum the the fuel pump, either during cranking or for that an initial one 2nd after transforming on the ignition switch, look an initial for fuse number 10, a 15-amp, in the under-hood fuse box, climate fuse number 8, a 7.5-amp fuse in the inside fuse box on the left end of the dash. The inside fuse crate is likewise where you'll uncover two fuel pump relays. Both need to turn on for the pump come run. Relay number 1 turns on once the ignition switch is turn on. Relay number 2 is turn on by the Engine computer system for that very first one second, climate again during engine rotation, (cranking or running).If you get 12 volts come the fuel pump because that one second, however not again throughout cranking, the usual suspects come to be the crankshaft place sensor and also the camshaft place sensor. The is your signals the tell the Engine computer when the engine is rotating and it is time to rotate on that second fuel pump relay. Through the signal missing from one of those sensors, you will not have spark either since the computer system does not understand when to fire the ignition coils.Before friend randomly change a sensor, read and also record any kind of diagnostic error codes. Normally when a component is referenced in a error code, the is actually the cause of the code just about half of the time. First we have to dominance out wiring and also connector terminal problems. In the case of this sensors, castle do have a fairly high fail rate, yet be aware it can be difficult for a error code related to them come set, for this reason just due to the fact that there is no error code, the does not prove the sensors room good.Please explain the symptom you are trying to fix if we must go further, and also any related history leading as much as the problem.
