3.9 efi HELP Calling PH Bods

[Mrs Fish]

James here;

Really need some pointers. My brother has a 3.9 efi rangerover which has decided to run PERFECTLY when started however when starting both cold and hot it turnover and struggles to catch and requires 5-10secs of turning over with throttle pumping to start...once going is perfect.

We've changed HT leads, Plugs, Distrib Cap, Coil...the only thing we can think of is the cold start temp sensor but it still wasn't happy when left for 30mins from hot so diubtful this is the cause...

ANY SUGGESTIONS PLEASE

James

[Mrs Fish]

Will do but the fact that it runs foine once started is suggesting sensor etc?

[Mrs Fish]

What was the result a new EFI?

[Mrs Fish]

Sorry re read my post didn't wish to sound off hand...Interesting to see a corroded ECU, will suggest. If corroded why does it run fine when started?

[Mrs Fish]

Will go through with my brother soon. Cheers

[Mrs Fish]
