I've always been rather amazed at some peoples attitudes toward mechanics, and generally
"guys that are rather helpful and knowledgeable in the automotive hobby"
I know that if your a "car guy" you'll have had at least a few family members or neighbors ask you, too look at their car on occasion.
KEEP IN MIND I GENERALLY TRY TO TREAT MY NEIGHBORS LIKE I WOULD LIKE TOO BE TREATED AS I WANT TO MAINTAIN A VERY FRIENDLY ATMOSPHERE IN THE NEIGHBORHOOD , THE LAST THING I NEED IS SOME MRS KRAVITS
ONE REASON I GENERALLY TRY TO HELP MY NEIGHBORS...
AS I'M CONSTANTLY WORKING ON PERFORMANCE CARS, AND WANT TO GO THAT EXTRA MILE TO NOT HAVE PERSONALITY CONFLICTS
as most of you will come to realize automotive diagnostic skill is mostly science, part art,
and a great deal of hands on experience helps,you'll need some basic diagnostic tools and a good understanding of how the automotive sub-systems work,
but a logical step by step, isolate and test mentality is critical,
you can,t assume a damn thing.
one of the local guys dropped by to ask me if I would look at his 2005 Toyota corolla which he says ran just fine yesterday, but failed to start this morning.
well I agreed to give it quick look, and I brought over my code scanner , pressure/vacuum gauge,and a multi meter.
the first thing I did was to turn on the head lights and ask him to try to start the car, as generally if its a bad battery connection or weak battery charge, the head lights and frequently the dash gauges will dim noticeably under the increased amp loads.
the multi meter shower 12.87 volts and no significant change when the ignition key was turned.
well turning the key did NOTHING,
no click from the starter and no lights dimming...nothing, so I pulled trouble codes and found only that it showed their may be a problem with the emissions/evaporator system.
Now That,s not going to be the source of the no start issues, So, I pulled a dip-stick too see if the oil, or lack of oil, or any coolant in the oil could tell me anything , ..nothing there, and the oil level and condition looked reasonably good.
So,I started checking the electrical fuses,
as I could not hear the tank fuel pump run and
I noticed,the security system red blinker light the dash, was not coming on.
this leads me to think the security system may be a factor, in the no start condition, as the starter is not even clicking.
all through , me having worked through this check list the owner seems to be less than pleased that I can,t throw a hand full of magic, fairy dust on the car and instantly cure the problem.
I suggested that it would be helpful if he owned a factory shop manual.......he thought that was absurd.
I will continue to diagnose the issue at least for awhile....depending on the owners attitude of course ,
but asking for mechanical help and diagnostic time, and having someone experienced, who is willing to provide free diagnostic time ...
and the owner of the car having an attitude issue, because the guy testing and diagnosing can,t instantly cure the problem,
seems rather odd to my way of thinking.

Inspect the relay continuity.
Using an ohmmeter, check that there is continuity between terminals 1 and 2. If there is no continuity, replace the relay.
Check that there is no continuity between terminals 3 and 5. If there is continuity, replace the relay.
Inspect the relay operation.
Apply battery positive voltage across terminals 1 and 2.
Using an ohmmeter, check that there is continuity between terminals 3 and 5. If there is no continuity, replace the relay.
