Emission test kills my car??

Hey guy!
Hope everybody is having a great weekend so far!!
Well I took my bird over to get new tires put on and get the emissions checked so I can make it all legal. I have had no issues with the car and she's running great......but.. when the guy hooked her to test the emission it would not start?? I was what the heck??? We pushed the car out and I got in and it started right back up. We pulled her back in and he left it running and hooked it up again and when he was brining it up to speed/RPM's it cut off again...needless to say I was stumped. My sons and I jumped back into the car and it fired right back up and ran perfect all the way home.

One thing I did notice was when he hooked it up and it would not start was I don't think I could hear the fuel pump..was a bit noisy there but I really think the pump shut down..but not sure??

Any words of wisdom from you guys would be well welcome.
Thank you!!
Rod
PS I have a few pics of the car but don't know how to post them..maybe somebody could post them for me.

See the Tech section for two articles on Fuel System Diagnosis and Fuel Pump Diagnosis. A noisy pump can mean its on the way out, but run the diagnostics first.

Inertia switch in the trunk may have been cutting out the pump. was the car on the dyne or on an angle. This is the only thing i can think of??

Paulie,
The car was nice and level. I drove the car on the highway and in town with no issues. Today my sons were with me (both full grown men now) they were both commenting how good it ran and how smooth.
I keep thinking maybe it was something in that guy's emission machine or maybe somebody jumped a wire some place in the car that may have caused this. I will try to hit another emissions place in the next few days and see if it shuts down again.

OK normally they do not hook things to the car directly. The tach pickup is normally hall effect and not hooked directly to the car. But if something is hooked to the electrical system in the car it may be killing the spark. Its hard to figure without knowing what the guy did or what he hooked up to the car. What emission test do they do in your state?? Do they run a ASM 25/25?? Or just an idle 2500 rpm??? That would answer a lot of questions.

Not sure what the test is or what he hooked up.... I'm in Gwinnett Co. Georgia. I did see him stick the reading tubes in the tail pipes and the car is running in gear like on a dyno he gets it up to speed/RPM's for a few minutes but thats all I know.

I have had fuel issues on my mustangs and my pickup but this seems to be very different because they all cut off or never started.

Thanks Pete was going through that tech section and some great stuff in there. I will try to do a bit more trouble shooting tomorrow.

Thanks !

The Tech section is good thats a given. But how can you trouble shoot a system that is WORKING?????? Just curious!!!!

I'm still trying to figure out that one too. I guess if it does it at another emission tester then I know it's my car..lol

The question is WHY????? Makes no sense that testing the car will cause the pump to cut out??? Makes no sense whatsoever

I'm with you Paulie,
Going to try to take it to another place tomorrow been too ill lately to mess with it.
I did drive it around a little over 60 miles with no issues and it sat for a week and started right up with no problems.
