Hi all
My Hilux has suddenly become hard to start.
Car is in good condition regular service 180 000km on the clock and I follow a starting procedure for a diesel.
The first start is fine
Any starts after this and the starter is slow as if the battery is going dead.
I have replaced the battery and glow plugs.
The symptoms still persist.
Self diagnosis has lead me to initiating the glow plug warm up two to six times with some success.
An Auto electrician diagnosed and replaced the glow plugs.
I am at a loss as to where to go next in problem solving
Any thoughts would be appreciated
Chris

I would be checking all earth points are clean and tight and also put the new battery on charge because they sometimes sit on a shelf for a long time so need a good charge to get them back up to100%

My 93 LN106 was getting hard to start on the first start.
Replaced the battery, but still drained that trying to start it!
Took it to my mechanic who had it for a week & started it every day no problems (and his workshop is as freezing as my garage).
Turns out if I start it at least every 4-5 days, it starts fine. If I leave it say 2 weeks - problems.
I wonder if it is a fuel issue (i.e. fuel draining completely out of the system if not started for too long)?

Do you have a parasitic draw on the battery? Something that's drawing current even while the ignition is off? Some accessory, maybe a relay for lights or something. I had something similar, I had to swap out a relay to f ix it. It will stuff the battery faster too if you leave it

I don't think so mate. Nothing electrical has been added to the Old Girl since driving lights about 20yrs ago. And the previous battery lasted 10+ years. Unless perhaps relay has recently gone bad?
Sometimes I was finding if I pumped the little pump thingy on top of the fuel filter I could get it started, which is why I was wondering about a fuel problem? But then even that stopped being a solution. Starting it at least once a week seems to work though?

It may be a small fuel leak that is draining the fuel back to the tank and creating an airlock, I had this after changing a fuel filter and the gasket didn’t seat properly , it was fineto start anytime as long as I didn’t leave it for more than 48hrs
Or a parasitic power drawer which your starter motor can even be doing. I had that on an excavator

Does it crank out over ok and not start or is it sluggish to crank over?

With the new battery it cranks over fine. But after 30 secs or so of trying even the new battery would run out of puff.

No fuel up at the engine end is my suspicion. It had a 2nd hand fuel pump put in maybe 10+ years ago after the original one died.

10+ days of not starting it seems to be when I run into problems, so I start it every 4-5 days now which seems to work.

Parasitic power drawer - yeah maybe. It had a non-genuine starter motor put in about 10 yrs ago which still starts it fine though. Not sure if the mechanic checked for a power drain when he had it for a week? Think he may have?
