not a ford, but hoping for help

[speadfreak]

I have a brand X work truck. It has a 4.3 v6. If the thing is cold, it will not start. It is getting spark, and it has 60psi fuel pressure when cranking. If I spray starting fluid on the air cleaner it will stumble to a start and then run beautifully for as long as I want, unless I shut it off for about 15 minutes.....then I have to spray starting fluid to get it to start again. I replaced the air inlet temp. sensor and the map sensor, but no change. It's like it's not getting any fuel on the intitial startup. Like I say, I know this is not a mustang question, but there seem to be alot of people on here that have a mechanical expertise that far exceeds mine.........thanks

Wait, where is JR's earlier post with the go cart comment?

Can you perhaps tell us the type of fuel injection (if applicable) that you have? This is a GM product, right?

Knowing if it is SEFI, CFI, etc will help.

Good luck.

It's a 4.3 vortec motor in an S10 blazer. It is the older style vortec with the tuned port intake and the throttle body facing strait forward.

Have you checked out the infamous CPI symptoms? Your situation kinda sounds like it could be related.
