Hard to start when hot

[murph the surf]

Recently bought a 2000 3ld Hilux

It had been out of rego and not used for some time.

We are having trouble starting it when its hot (engine at running temp)

Have to crank it way too much before she fires

It starts perfect when the engine is cold.

Has anybody had similar problems or does anybody know how to remedy this?

Cheers

how long left unstarted? could have poor compression when hot, or poor fuel pressure. Check valve clearances. Milage? Has it got a working air filter? Are fuel filters clean? Any water in fuell or tank? NB water into pump usually means destruction of pump. Could have cracked head? Not uncommon on the iron head motors of that age/250,000km. Is the motor overheating-do not trust the OEM temp guage-they're innacurate at best. Is the hot idle reliable 800rpm and torquey w/out smoke/hesitation? rsvp CHECK OIL Level and quality!!!!!! Was it from coastal area?

Hi Manxman

The car had been run a couple of times as it had to have a blue slip before we bought it.

Have a new fuel filter to fit after we drain the fuel tank

It has 201200kms on the clock

Does not blow smoke and runs well

Yes it was from a coastal area

Hope to investigate more over the weekend

Cheers

I'm a litt;e worried that the exposed bores may have rusted from the wet/salt air if not run often enough. I'm also suspicious of the fuel pump/filtration system. Pleaset urn on tap below fuell filter body and let drain 10 seconds. you're looking for water. reprime when finished. If no tap, you need to remove, empty ,examine fuilds and replace filter/and reprime. you need not renew unless losts of water. it should also have a water level switch in the base of the filter--make sure it's working. If water found, drain tank completely and discard fuel--it's prob contaminated. There also is the possibility of algae in the tank-same solution. it comes from water content and storage of fuel. it may collect around tank filter as motor warms up. motor will starve of fuel, particularly under load at speed. tank will need full cleanout and new internal filter. Easy test for tank/fuel probs is to connect good temp fuel supply to eng bay fuel filter and see if problem continues. You can test the filter by bypassing it, but it's not recommended-any dirt into pump will do much damage. $$$$$$ it's a 10 micron filter or less, that's pretty small. further, and quite common at that age-the primer may be faulty. if it never goes hard it's prob leaking air. replace from ebay.
