Title: Water Hazard
Post by: Wolverine69 on August 04, 2009, 06:08:36 PM
Hello all.
As my previous posts showed i was having problems with my Rx7 FD3s stalling and not starting during wet weather so i changed all my leads and plugs sprayed all exposed and not exposed electrical connections and this seems to have done the trick, at least i thought until a heavy downpour the other day and low and behold it happened again.
I just happen to have a friend with me who said the carpet felt a bit soggy in the passenger footwell upon inspection the carpet was soaking and the water was all over the cables going into my ecu .
Has anyone had this problem and could you suggest where the water is coming from and would this be the problem for the starting?:3Confused

have you looked to see if the grommet in the bulkhead is in properly?

may also be the door seals?
