Engine dying after start up
Ok,I have a 91 runner 3.0 auto.Once in awhile after driving for awhile and I shut it off and go to start it again it will fire,idle really low, 2-300 rpms,then die.When I try to restart it,it will chug like it wants to start(tach won't even register) and die again.After awhile of doing that I can eventually get it running by feathering the gas but for a minute it will rev slow and stumble and puff a little black smoke.Any ideas?

No check engine light.It does run good again after I get it to run.It has a new tps,fuel dampener,1 new injector,all new injector seals,timing belt.It doesn't do it while driving and it doesn't die unless I just started it up.

I actually got tired of trying so I took it to the dealer and payed 44.50 to get the diagnosis.My dash pot was also stuck causing the fluctuating idle,so they fixed that and now I have to put the new cold start injector in.This 91 is the same way,I payed $5,000 for it and have put well over $2,000 in repairs into it.Water pump,tensioner pully,timing belt,injector,injector seals,fuel dampner,brakes,etc...Our 87 with 240,000 on it has only had to have the alternator replaced in the last 4 years.

I would not be surprised in the least if that was the cause of the problems.

it aint the cold start injector,it only does what its told,its the cold start timer its in the water manifold on the rear of the engine.every time you hit the starter it resets,and squirts more gas through the cold start injector.

They said they tested everything and the injector was stuck.Something about it building up with pressure.Then when I picked it up they said it was stuck open.If it was stuck open then it doesn't seem to me that it would build up with pressure would it?I don't know exactly but thats what he said
