So I have been dealing with this issue for a long time now. At first, about once a year the car just wouldn't start. It would crank and crank but just not ignite. After about 20 minutes it would start up fine and no problems for a year. This went on for a while until it became more frequent and I finally googled the issue and found out it was the main furl relay. I got this fixed a little over a year ago and things seemed fine.

Then a couple of months ago this happened again. And now about once a week the car will start up fine and then start shaking and turn off. When this happens I either have to wait a while, or I start it and just before it dies I hold in the gas a little bit to keep it from dying and eventually it won't dye when I let off.

I'm guessing there is an issue with the fuel delivery but it seems like the mechanics can't figure it out because they can never reproduce it. I would love some suggestions because I'm just not ready for a new car.

 

did you get a new relay or did they fix the old one?

 

I got a new relay. It wasn't done at a dealership either, just had a mechanic order a new one and put it in. It seemed to solve the issue pretty well for a while.

 

A buddy of mine thinks this could be a issue with the oxygen sensor. Any ideas from you guys?

 

nobody?

 

ignightor or ignition switch is where I would look first

 

i agree with the mechanic, the only reason why it whould shake off and die whould be from a shortage of fuel.
multiple things that you can check, the o2 sensor, fuel pump, or maybe its not getting ingited well so maybe the sparkplugs. worst comes the worst there could be some things like sand and unnescessary crap in your cylinders, i had a car that got stuck in the mudbank and had the same exact problem.
does your car by any chance have a very low idle when you have your running?

 

^put a fuel pressure guage inline between the FPR and rails, if it is constant PSI then fuel delivery is not your issue

 

^ check that first. also it sounds to me like it doesn't want to idle on a cold motor.
possibly the IACV under the throttle body could be bad.

 

Thanks for the advice guys. I'm going to take it in sometime in the next few days.

I haven't noticed that the idle is any lower than normal. Its always acted the same when it comes to this stuff. The issue hasn't happened again (yet), but like I said it only happens once in a blue moon. Last time it happened was after I went to the grocery store and came back to the car and it didn't start, so its not really a cold motor.

I put in a bottle of fuel injector cleaner the other day, maybe its as simple as that (but I doubt it).

 

I'm having the same problem. please keep us updated

 

sometimes when I would put it in reverse and back up, the car would just shut off. It hasnt done it recently but it does happen every 3-4 months.

 

sound like it doesnt have enough fuel or air. first i think u should check ur air filter and clean ur throttle body good. what happen is throttle body clogs over time
