[__ Prayer __] Fuel pump misdiagnosis

Edward said:
Well you could identify the wire from run and use it alone without using NC on the relay.

I'm with air dancer on this. While I can do this stuff if I have to, I gladly pay someone else to work on my vehicle. I absolutely hate working on autos.

Run was where I thought it had to power.nissan uses run terms not on .btw it was the ecm removing ground a normal function for safety .the relay is bad and module is found and ordered
 
I've always heard that woes come in sets of 3 .... I'd say your brother has reached his limit for this cycle.

Sorry to hear Kohen had to have stitches. Those aren't fun at all.

Ugh I thought it was a fuel pump issue and the darn ignition switch is bad .it won't rub the fuel pump unless it's in start .it should run in both.not only that a dealer part to replace the broken module ugh.

My poor brother.

I've had a few nightmares with fuelpumps. One instance was an inertia switch in a Mustang. The switch exists in order to shut down the fuelpump in case of a roll over, or a severe impact. The problem with the switch was actually caused by an aftermarket stereo system (big boom box) located next to the switch. I've also had a Corvette that had an intermittent problem with fuel pressure. Turned out to be the regulator instead of the pump. But then a year later the pump went bad, intermittently too. The fuel pressure would drop 10psi and the car would run rough, just for it to clear up again. I know some fuel pumps also turn on for only a few seconds to pressurize the system until the car is running or cranking. They'll turn on, then off, and sometimes they get misdiagnosed as being bad because they are not running while being tested.

Just emphasizing that I know diagnosis can be difficult. Usually, I just jump the fuel pump directly where the terminals connect around the fuel tank, disconnecting everything electrically to the fuel pump but my jumper. I jump the pump on and test for fuel pressure. If okay, then I know it is nothing to do with the pump. Of course most dealerships have manuals that offer troubleshooting, providing a diagnosis tree.

G'luck and God bless,
William

I have this on loan.http://www.tooltopia.com/power-prob...gn=PLA&scid=scbplp6825257&sc_intid=PWPPPKIT03
 
I got that pump in and fixed.the relay was replaced
The module is a cheap one.I shouldn't have to force a connector on like that. Really have to push hard and jam in it to get a good connection.the pump was the problem along with the relay.Now the car needs a idle control valve.

Memoir of her ovarian cancer was named that line.

I read her book, what she went through to find a cure, and how she finally accepted what was happening towards the end of her life.

Her husband, Gene Wilder, was so in love with her; he was devastated by her death.
