Engine starts, then dies

[crager34]

The thing starts right up, then dies... over and over. I can rev it then I take my foot off the gas, it dies. Does it sound like the throttle positioning sensor to anyone? Also... if this does sound like the problem, where is it located? Autozone sells it for just under $26.

Check that MAS is firmly attached to the intake tube and that the connection to it is secure (unlug and replug). TPS is located on the throttle body upfront.

Thanks Tone!! Trying to download the manual from your site and it gets stuck at 3.57mb..... any ideas?

BTW - PV muffler I got from you awhile back.... IT ROCKS!

mine did this one night, then it just started working again, no clue why, though I am not too worried about it. someone suggested to me fuel pressure regulator, no clue though.

I live in Ohio.... wet outside...full tank of gas, new battery, upper 40's tempurture, first start in the morning....

Hopefully a $25 part will get this done.

Mine just did the smae thing at lunch.

I had a pinhole leak in my fuel pressure regulator, and it caused something similar. I'd start the car, it would rev, and then die.

Mine acted somewhat similar a few months ago. I changed my fuel filter and it has not happened since. That would be the cheapest place to start.

my VX does this repeatibly. Everyonce n a while I will attempt to start, then it dies...same..etc...attempt to start but keep gas on pedal it will stay started...but take foot off and it will die. Open gas cap and close AFTER you attempt to start and then it dies...and it will usually be ok.


not sure why...have checked all connections to anything that could be a culprit....I've been told to replace the fuel pressure regulator and that should fix it...

Started happening to me a about 6 months ago, I replaced the fuel filter then it stopped. However, It started happening again, this past weekend after I turtled my way into a gas after being on negative E, my guess is there was air in the tank plus the gas station was notorious for "bad gas", but thats all I could find at the time. (got to finish bad tank of gas)
Note:
If you are pressed for time, start the engine place right foot on gas pedal imediately, keeping it steady at about 1000rpms, put your left foot on the brake pedal (press hard), check your mirrors, shift into drive or reverse. Then take both feet off pedals(you may feel a jerk), it won't cut off at that point.

[SPAZZ]

off and on...sometimes it does it everytime you attempt o start...sometimes it doesn't happen for months.

replaced fuel filter...no help...cleaned EGR, no help, replaced pcv valve, no help, checked all hoses/electrical connections, no help

Went and purchased the TPS unit, then went to start up the Space Ship...... started right up and hasn't quit since. Maybe some air in the line... bad luck.... full moon... who knows.

I'm with SPAZZ on this one. My VX has exhibited the same behavior the entire time I've owned it. Occasionally it will just die - sometimes at a light - I have to drop it into neutral, start and goose it a little to get it to drive. After it sits for a while I can get in it and it starts right up - sometimes at high idle - after a while it stops doing it.

I've tried different fuel, changed gas filter, pcv, cleaned throttle body, ect. It still ocassionally does it - doesn't throw a code or anything (unless I jerk it into drive too quick after restarting in neutral - then the tranny light blinks until I restart).

I've gone so far as to think it's humidity related.

Initially I took it in, but the techs couldn't find anything wrong with it and couldn't reproduce the behavior. I've learned to live with it.

I just got this problem now too. Any solutions? I was on my honeymoon last week and it started up and died 5 times in a row in one day. Then i rev'd it up and it's been ok since. Taking it to the dealer tomorrow. One shop thought it might be an electronic starter switch that was going bad. Not sure what that is.
