1998 TB45 Dual Fuel Hard to Start in Mornings (sometimes)

[Bob]

My Patrol some mornings is extremely hard to Start and when it does only runs on about 4 cylinders for a couple of minutes.
Normally I start with no Pedal but when it plays up I have to depress the Accelerator fully . It then starts after quite a few attempts.
It then runs smoothly and will start first time for the rest of the Day.
The Car always starts on Petrol and switches to Gas after a couple of minutes.
It is like it is over fuelling if it fails to start first thing.

Hope you can understand my ramblings but before I take it to a Mechanic does anybody have any ideas ??

plugs leads ..... not sure if these have a dissy as such rotor cap and button ... how are your fuel filters recently got fuel from somewhere you have never used b4 ...... i know gas cars can be hard on spark plugs

Could be a number of things. As mentioned above I would be starting with plugs if they haven't been changed recently, then leads.

A comprehensive service on plugs, leads, vac lines , etc needs doing firstly.

then the coil pack, and then the Injectors themselves

Thanks for the replies guys and have taken all on board.
The bloody thing started first go this morning . It was 0 Degrees.
However I will do as you all have suggested .

sounds like you you have plenty of spark, but lacks a bit of fuel for start up.
Does your model have that inline cage filter, ??
Maybe give it a few pumps throttle wise on start up and see if that helps,
you must be getting up there mile wise now??
Replace all the vacuum hoses, cheap enough to do, and renew some of the fuel ines as well
Could be they have perished and cracked over time.

Hey mate, I'd be getting your injectors done if I was you, I had the same sort of thing going on with my tb45 GU, turned out 3 of the injectors were 70% blocked, and the others were leaking profusely when the engine was not running, causing it to be very hard to start.
Good Luck!

Thanks @Nickgu Booked in to get that and other things to be serviced. Funny thing is the Truck is starting first thing and running well at the moment.
Still getting all things serviced

Maybe as the temps a bit cooler, the computer is choking it a bit more and your now getting that bit more fuel that's needed to start better.
The fellers could be onto something , just dirty injectors?.
