Cold start issue! Help!

Teranchelope · 2nd January 2021, 16:12

My rover 75 cdti 04 facelift has gradually got more difficult to start from cold. Replaced all sensors, fuel filter 1 injector, all glow plugs. Desperate now, starts on Easystart and then pops and runs fine. Restarts hot okay. Fuel pressure voltage okay. 5v at ijectors when running. 1v ignition on. Ecu dry. Help! T4 diagnosis needed in Pulborough.

Try contacting cb750chris in Portsmouth, he has a T4 or download Toaf (use the search for more info) and diagnose the problem yourself.

Sorry no, not exactly local to me. But in the Tech help forum, two listings down is a list of traders with a T4, click on his name to send him either a mail or PM.

With a bit of luck he might even see this thread himself ...

It sounds like the glow plug relay is no its way out. Friend had the same problem with theirs. Checked the relay and it was burnt out inside but looked fine from the outside. It was changed with a 2nd hand one from a scrappy and it starts 1st turn of the key now.

Sounds like a failing injector. Try an injector leak back test.
