Intermittent crank-no start
Hi there,
986S which has intermittently been not starting. This seems to happen only when it is warm. After I come back a few hours later the car starts again.
The tach moves slight when I turn the key to on position (regardless of whether it starts or not) — ie up to 0 rpm.
I bypassed the fuel pump relay with no change. The fuel pump sounds like it is coming on. No CEL.
When I crank the engine and the car DOES start I see a subsequent tach bounce initially (eg up to around 200ish and then it goes to 1000rpm on ignition). When I crank and does NOT start I see no tach bounce.
If I understand correctly, this is what a CPS fail looks like? Is there anything else I can do to check other than replacing the part?
