Car wont start!!! need help!

Si Fi · April 14, 2011, 09:39:27 PM

Driving my RX7 last night (1996 FD) and changed gear then notice a drop in performance, by time I got home when i pulled up it was spluttering (as if it wasn\'t firing correctly) and vibrating.

Left it until i got home today from work and started it back up again and it started up but again was spluttering and vibrating then engine cut off after about 3 seconds or so? but now wont start up at all. when i turn the key it doesn\'t do much!

Any info will be appreciated, live in derby so not exactly around the corner to any specialists

Thanks guys.

How does the car actually sound, does it sound kinda like a tractor noise?

And does it settle when you get it up to 3000rpm?

Hi mate, when it was running, yeah it did kind of sound like a tractor, but as 3k on revs, it still wasn\'t ok and was sluggish to react when using the accelerator. luckily this happened not far from home!

thanks.

Hmmm I\'m guessing and this is only a guess but it sounds like a chipped tip but I maybe completely wrong hopefully someone can correct me if I am wrong

A video of the car would be best so we could see the problem

I hope not

lol. so do you reckon its a lack of compression is why its not starting up then? if it doesn\'t turn out to be that thanks for possible fault any way

That could possibly be the reason for not starting and sounding really rough, what was the idle speed roughly? Lower then usual?

Si Fi · April 14, 2011, 10:17:29 PM

when it was running, yeah it was lower than usual, approx around 800 revs?

One sec let me do a search and see if I can find a thread I remember from a while ago

sounded similar but mine was juddering more, bit like the feeling when a car is about to stall kind of but through different rev ranges???

Quick thing to check is the boost sensor pipe hasn\'t popped off so its running super rich (makes it see atmosphere all the time). Its a small sensor behind the throttle body with a small pipe between it and the plenum.

Hopefully it isn\'t anything serious, don\'t panic straight away and just check for all the simple stuff first.

I\'m not to sure then, from what you said it sounds like a chipped tip which is not the end of the world fortunately, but hopefully people smarter then me will be able to pin point what the problem could be

Have you checked inside the engine bay? Anything look suspicious?
