Reported fix

therefore we just cleaned the rod as much as possible and cleaned the 'radial connector' on the positive cable with electric cleaner, applied dielectric grease and reconnect the cable. This solved the issue for me, you may want to check it up, it's free just a bit of time to clean the connector.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hey all, I have a 2003 Boxster base (MT) with around 68,000 miles. The car has been having a no crank, no start problem. When it happens, I have full power, the gauges move and I hear the fuel pump. However, when I turn the key nothing happens. No crank, no start. Rowing through the gears and removing/replacing the key gets it started but sometimes it takes a little while. I have replaced the battery, clutch safety switch and the ignition switch but the problem remains. There are no other electrical problems, just the no crank, no start. I would be grateful for any advice anyone has. I'm not sure where to go next (except a shop). Thank you!

First: I would change out the starter relay. They are not expensive and easy to change out. It is in one of the relay panels in the trunk. Second: In the engine bay next to the power steering reservoir is a small black plastic box. inside is a connection for a main power ground point. Make sure it is clean and tight. Third: Check the connections at the starter and make sure they are clean and tight. Do those three things then let us know how you go.

POST 3 / ORIGINAL POSTEROriginal post

I will check the connections and order the relay today. Thank you for your concise reply. Much appreciated!

The relay should be a very common automotive relay. So you should be able to remove it then take it to any auto parts store and get a correct replacement.

Ah, that's even better. Thank you.

POST 6Original post

Hello Tacos, I had the same issue on my '07 987CS and drove me nuts as you turn the key and everything on the dash lights up but the engine completely dead (not even a click from the starter). I removed the starter just to find that it was ok, the relays were fine as well.. The positive cable from the battery goes into a power distribution block (with large fuses) this distribution block it is located on top of the glovebox. However, the positive cable from the battery attaches into a Mickey Mouse designed connector on the firewall (battery side) and this unusual connector has radial metal contact stripes that attached (by friction only) into a rod that goes through then firewall this rod comes from the power distribution box. After we finally ID the culprit, we found out that the positive cable with the funky design was discontinued by Porsche.. therefore we just cleaned the rod as much as possible and cleaned the 'radial connector' on the positive cable with electric cleaner, applied dielectric grease and reconnect the cable. This solved the issue for me, you may want to check it up, it's free just a bit of time to clean the connector. Good Luck!

check and clean the ground connection of the battery negative cable where it attaches to the body. While your at it.
