I have a 93 with a 3.0.
I just replaced the intake manifold gaskets and now it cranks and cranks before it will start when cold and worse as it gets colder out.
New antifreeze,coolant sensor.
Started fine before the job,no other changes,everything is hooked back up and right.
Fuel pressure good,has spark.
Anyone experience this?

 

'Ever since I fixed my car... it's broke'. you must have missed something. first why did you replace the intake gaskets, I rarely hear of them going bad? I know that one could make an error in installing the gasket not only backwards but they slip out of position very easily. try spraying carb cleaner around the gaskets once it's started. if idle speed changes, you found your problem.

 

All connections appear to be good.
No vacuum leaks.
Once it starts it runs fine.
No codes.

 

Must be reverse magic. worked fine before you fixed it and now it doesn't. Well I'll ask you another stupid question. any chance you mixed up the fuel line if you took them off? I know you're going to say no, but since we can't see what you did, and can't look at your car, all we can do is ask you stupid questions!!

 

No stupid questions,you never know if it will spark a memory block or other possibility.
But no the lines are not crossed,they are two different sizes as well.

 

I knew you'd say that. Well you confirmed everything is perfect as it was before you 'fixed' it. so I guess the only other alternative is to take it all the way back apart and figure out where you messed up.

 

Well knowing I did not mess up,I tried a map sensor,no change,then a throttle position sensor,big change,starts a lot better(maybe it got bumped to hard,maybe a bad connection ?).
It used to start in one or less revolution,now about two full revolutions to start,I can live with that,but I will play with it a little more,maybe the oil/oil pressure switch.

 

A bad TPS would have set a check engine light. I like the tossing new parts at it hoping for the best. Why are you looking at the oil/ oil pressure switch?

 

No light(it does work).
I do not like spending $ on parts I do not need,but finding no obvious problems,sometimes you have few choices.
If the oil pressure switch does not see pressure,it may effect its starting.

 

i know for a fact that oil press dont afect starting at all on these moters. yall be wastin time chasin that one, exept if maybe she's locked up from no oil. i had this gal that blowed up her 3.0 dayt cuz the cam plug fell out and dumped all the oil after it cooled down it still started and ran even with the busted rod. it got that rod laying around if yall want to see a pic
