Right i have a ongoing problem if its a heavy downpour and when driving in heavy rain ...the car will start hesitating then pop/bang and dies and wont restart for say 20 mins , the dizzy and leads dont look soaked or anything and my rain tray is intact...hmmm, i fear it may be down to replacing my cap and leads about 6 mnths ago with blueprint/adt items....
any ideas?
cheers

wd40 is your friend but it's not working for me. I'm having similar issues in heavy down pours.

Re: tubby + rain dont mix
Same I problem here, it drives fine until it's on boost, even low boost setting (6psi) sets it off, has a new coil and ignitor. Dizzy seems fine and dry, if it's any help, my car can be sitting in torrential rain and then drive ok, it'l seems to be surface water it has trouble with.
Re: tubby + rain dont mix
Check your plug wells. I had the same issue and found that it was water leaking down into them. Dried out and swapped to genuine leads and all was fine. Might not be your issue but definitely worth checking

Re: tubby + rain dont mix
I use and and abuse my Rev3 24/7 all year, regardless of weather. Never had a problem in the rain. Ever.
However, i did replace coil, leads, cap and rotor arm with new Toyota items 2 years ago, plugs are changed annually, and alternator was replaced 3 years ago.

Re: tubby + rain dont mix
My rev2 was the same, rain didn't bother it the whole time i had it, to be fair i've not really inspected it at all, the coil was changed as the old one was goosed. I've yet to check leads, plug wells did cross my mind but it's genuine toyota leads on it.

It will be the coil, take it off and have a look, it will have cracks on it that let water in.

+1. The casing gets brittle over time and cracks allowing water ingress. That would be my 1st port of call.
Then check for water in the plug Wells.
Re: tubby + rain dont mix
there's a big white plug connector under the engine bay fusebox and you can just about reach it with your hand . I had one that used to do it . i'd sit there for 10 minutes and it would dry out. give it a rattle next time it does it.

Re: tubby + rain dont mix
Can you even buy a non toyota coil? Surely if it wasnt a toyota one it would be a denso coil, which would be the same thing anyway?
Edit: nevermid noticed several unbranded versions for sale.

Re: tubby + rain dont mix
Had the same problem in my old rev2 tubby drove me nuts until I sorted it out. If I can dig out my old post on mr2oc I'll post it here .
But anyways
My tubby left me stranded in the rain in a village like 90 miles away from home I didn't want this again so I found my problem
First my tubby had original ht leads apart from the king lead (not sure why it was a magnecor this got swapped for a brand new pair of Toyota ht leads) they fitted better magnacor are crap I don't care what anyone says Toyota ones are far better
But the car struggled to start it would splutter into life in the rain again this wasn't right so I dug deeper
Noticed my coil pack was new but was not original Toyota this got swapped for a second hand original one along with the cold start switch
And the combination of all 3 parts transformed the car. It ran smother was quicker returned better mpg and did not splutter into life in the rain and on boost in the rain it was fine
If your having issues starting your car in the rain I can't stress enougj change your coil pack if it looks a bit worn and only for a Toyota one
Don't use other ht leads apart from Toyota
Give the coil bracket a good clean and all other earth points
I had sorted a couple of wet start issues for other members a few years ago and they all have been easy over looked problems
I'll look for my post on mr2oc and show the difference between coils
