you know, i always bought caddys from the 60`s and 70`s cause i can fiddle with them myself...i never bought one that was made after 1985..well, when i got a call about a 1990 deville going for dirt cheap and no km`s for its age, what did i do ? i bought it

everything was great untill about three months ago
it wouldnt start, the engine will turn, no warning lights come one it`ll run for about 1 second then stall...if you let it sit between 5 to 10 mins the car will run perfectly...and it happens only once in a blue moon

after the first couple of times it did it i threw some NOs fuel system cleaner in it to a mostly full tank...it didnt again till about a month after that, now with it getting colder out its happening more and more often, sometimes twice a day

totally driving me nuts

i asked the chev dealership that i bought it from about it and they said they had no idea
i phoned up the local caddy store and spoke to them and they had never heard of such a thing , and that they`d need it for a day or two to look for it and hope it dosnt start for them....morons

anywho ive heard it could be a few things , fuel pump relay...the fuel pump itsself...injectors?

im pulling my hair out about it...its hard to impress a girl with a Cadillac if it only starts periodically

any ideas?

Do you hear the fuel pump working for a few seconds with ignition ON, the engine OFF whent IT happens?
Keep starting the car in two steps: ignition ON, wait to hear the fuel pump working for a few seconds, when start the car. Did you notice how much gasoline you had in your tank when IT happened? Fuel pressure gauge would be helpful too, to make sure you have enough pressure when it happens.

i check that everytime....i park next to a cement wall so with the window down i can hear it ....im guilty of not waiting everytime....but even when i wait and hear it prime it still messes up....i have noticed that when it has less then ten litres of gass in it and in a courner the car will hesitate...but from what ive been told (and i could be wrong) that , that is not uncommon for GMs of the early ninties

if the car was plugged into a code reader would that tell the issue ?
and could it be the gas cap itsself?

like the car is tip top and was treated very well by the pervious owner..tons of money has been dropped into it and you could eat off the engine

im going to go buy some smokes

wish me luck
