Hard to start warm

[AJWolfe]

I have a 92 LC that starts OK when cold but doesn't want to start again after it's been running. Let it sit a minute and she'll start right back up. Any ideas on what may be the cause? Thanks.

Check to see if you have a check engine light when you turn the key to the ON position.
If you do not see a CEL do a search under EFI relay.
Very common issue for the 3fe...

Guessed you had a 91-92 before opening the thread. Not a guarantee, but you have the classic symptom of a failing 3FE fuel pressure regulator.

I thought it was the EFI fuse overheating issue thing. I keep some canned air in the cruiser for this issue. Turn can upside down and spray onto the fuse. It starts right back up.

EFI fuse or EFI relay?
Fuses don't overheat they just blow

You know what I mean.

FrankTorres has the EFI relay issue covered: Test is to make sure (when it's acting up) whether the CEL is illuminated (as it should be) with engine OFF, key in ON position.

Come to think of it, AJ didn't really give us all that much to go on...

Thanks for the help. As would be the case, I can't seem to get it to act up again right now. The EFI relay does seem to get warm as the engine runs. Don't know if this is normal or not. The engine runs a bit rough too at idle. I'm just learning about these so I don't know if this is normal or not (especially for an engine with over 200K miles).

My Sequoia has about the same miles and purrs like an only slightly angry kitten. The FJ80 is like a larger, angrier kitten. Bobcat maybe...
