Starting problems with Mitsubishi Pajera 2.8D

[Chittychangchang]

I like to try and fix my car myself and do my own servicing but this problem has me stumped.

When i turn the ignition it take about 30 seconds for the engine to fire up.

I've replaced the heater plugs!

What else could be the problem?

Thanks in advance

Small leak in injector pump allowing fuel pressure to drop until you crank it enough. Easily fixed by

pump specialist

Does it take 30 seconds for it to turn over, then fire quickley, or does it turn over for 30 seconds before firing?

It takes 30 seconds of trying to start, then fires up sluggedly with my foot on the accelerator.

thanks for your reply

Possibly a leak in the pump as said by Maybole.

But I suspect a cracked injector is more likely the cause. A cracked injector will require the engine to crank for an extended period of time to re-prime the common rail with sufficient pressure to fire. It will then run OK once started, but you're still losing efficiency and power.

You may be able to identify the cracked injector visibly with the engine running. It will appear as a slight atomisation coming from the injector body and you may actually smell the raw fuel. If you can't ID visually, then you're going to have to isolate each pot's fuel supply one by one, cranking each time to see if the cranking period reduces as each pot is isolated. If the cranking time reduces significantly when say pot 3 is isolated, bingo.

Here's a link to a Toyota handbook on injection diagnostics. Pretty hands on and may be of some use to you.
