I have a 1991 Pontiac firebird but it stalls in neutral drive reverse any gear I changed the fuel filter fuel pump throtle position sensor and it still does it what could be causing this

Doe,s the car idle and rev up while in park?

Yeah for like maybe a minute two at max

But ten minutes ago it ran and I drove it half way around the block then it shut off got real hot and won't even turn over now I been working on it all day

Sound,s like you may have a coolant issue all so,meaning bad water pump,thermostat,for the over heating,all so check the oil pressure it could be causing all the issue,s of the over heating and shut down all so,meaning bad oil pump,it will cause it to stall and heat up like that to.

So oil pump thermostat and what about ecm? I see that allot

Ecm issue could cause issue of shut down,but not heating issue,and if it were ecm doing it,your engine light would flash on and off in this model to give you code.

It flashes like three times and then four times but I don't know how to tell the codes I been looking and found nothing

Give me few minutes to find the code,be right back with you.

The code is a bad cam shaft postion sensor,PO340

Would that cause it to do that though it won't even drive it stays shutting off

And how did you find the codes because it might be doing more then that it just blinks a few times

Cam shaft postion sensor

Ahh would that cause it to stall the car out like that

I have code book,you said three blinks,then four,code isPO340.the three is first blink and four follow,s.

Yes it will cause the stalling.

Correct and do you know the cost of those

According where you purchase,but price between 25 and 70,just depends where you get it.

Sweet you have been so helpful thank you

Where do I get a.book with those codes in case any other codes come up
