starts and dies

[willys924]

I recently purchased 2 924 porches 1 1979 other is a 77 924. I'm having a problem with the 79 it seems to start and run and die (30 sec to 1 min long ) when it starts it runs strong and then the gas peddle turns to mush and die sometimes it starts right up other times it won't . I purchased with full reciepts from 79 I got a dentist went out and bought him a new porche . also have between the 2 cars have over $10,000 worth of reciepts new head and motors and something was mentioned about a custom geared rearend . How could I tell if the cars are "s" ? One has a 150 mph speedometer the other is 165 speedometer is one better, in suspension set ups or is there a real difference?Well thank you for any advice . I have so many ?'s P.S these vehicles were pulled out of a backyard in old property missing a couple of parts on one particular car the other is complete might sell one.

lol with all kidding aside, both of your cars are just plain 924 models. you dont have an S car. the S was only around in the mid to late 80's (i believe.. someone correct me if i'm wrong).

you could have a problem with the fuel pressure in your 79. it sounds like you're losing pressure in the system and the car dies.. either that or a vacuum leak. but i dont suppose it's a vacuum leak because you say the gas pedal turns to mush... in a vacuum leak, if you pressed the gas, it'd keep the car alive... provided the leak was small enough. a bigger leak wouldn't let the engine run for a minute before dying..

I'd hook up a fuel pressure gauge on your fuel rail and test pressure there...

Early 924's are prime candidates for a small block V-8. Possibly the best thing one could ever do for the car.
