Re: Clio rough start from cold

There's a few things that you need to check on any diesel engine that has cold starting problems. compressions which these suffer from gummed up pistons.A good rpm is a must. If the engine turns over to slowly the pump cannot generate enough fuel pressure to activate start of injection causing hard starting problems.Checking pre heating check engine coolant tempature. attach multimeter to glow plug terminal and earth start vehicle up observe glow plug period at 20c tempature glow plug period should be approx 15 sec's
