Quoted From Xyius:
So you’re having a no start condition? I am assuming it is a crank no start condition. You don’t want to go on assumptions, find out if it has fuel. The first thing I would do is hook up a fuel pressure gague and measure the fuel pressure. Compare this reading with the specs. I think on those older model Cavaliers (Before 2000, there is no quick connect test port and you must disconnect the fuel line going into the fuel rail and tee into it.
and if i have good fuel pressure up too 40 pounds?
Quoted From dreamer2355:
First off, is there a check engine light?
How are you testing for spark and/or fuel?
Screw driver and jumping a spark to engine block. ALSO i sprayed carby cleaner into it and it tried to fire.

I cleared all DTC codes the other day and 2 of them revolved around crank. Which leads me to think it can be that but then it wouldnt have spark? a few others where throttle body problems but i think thats when i unplugged it and set some codes off.
Quoted From Beefy:
How many miles are on this car? I have an old S-10 that acted very similar to your Cavalier. It had 180k miles on it. The catalytic converter was factory original, and when it heated up and the innards expanded, it essentially pinched off the exhaust. I sawed it off and ran a straight pipe. Ran great! Just something else to consider if the mileage is up there. Actually, I misread yer post a bit, so disregard. But, if your car fires up fine when cold, and will stall and not start for awhile when hot, and has a billion miles on it, then.. yeh.. Crap..
supposedly the engine has 96,000 miles on it and the body has close to 200,000 on it. so i do not know.
Quoted From killman:
GM cars (especially FWD) seem to have a lot of problems with the fuel pressure regulators leaking internally and flooding out the engine, causing poor fuel ecomony, and rough running with hard/no hot restart problems. You can test it easily by using a Mity-Vac pump and clear tubing on the FPR vacuum port to see if raw gas is coming out and if the FPR is holding proper vacuum for a period of time. You can see if there is gas in the FPR from a broken diaphragm if you use a long enough piece of clear tubing.
So if that is my problem how hard is it to fix this regulator?

And this problem of it restarting just fine after it sits for a while is still the regulator?
