Cranks will not start?

1992 buick lesabre cold winter starting problem. Car starts fine but as it warms up a relay can be heard clicking under the passenger dash check engine light flashes on and off temp light flashes and then engine quits. Restarting is tricky, push accelerator to the floor and crank. May start then relay clicks on and off and check engine light flashes. If you keepit running , after it is warmed up completely the car runs just fine. What needs to be changed? Coolant temperature sensor has been changed and manifold air temp sensor has been changed. New crank sensor has been done also.

Its the computer

Ive seen once or twice where its been a bad ground or a bad connectoin at the starter.

The car will not start sometimes, it has a security light that comes on. You have to wait for the light to go out, usually takes about two to three minutes. When the light goes out the car will start. Any ideas on what the problem is and how to fix it.

I have a 92 Buick LaSabre, 118,000 miles, 3.8v6 which sometimes when I shut the car off and try and re-start it will crank fine but not start. After waiting a short period of time (5 to 20 mins) will all of the sudden start. This happens randomly and could happen after a short 10 mile trip to the store or after a 300 mile trip but not all the time. Yesterday while pulling up to a stop light the moter quit and ther car wouldn't start for about 15 mins. It's almost like something in the ignition is heating up and needs to cool down. Any ideas would be great.

Please Please please let me know if you have a reply to your question. I have the same car with the same problem. My buick is in the shop right now and ill let you know if I find anything out. Thanks.

Hi I have a 92 buick lesabre first of all when starting I have to give it gas to keep it running but only usally for 15-30 secs then its fine also when driving at 55+ it will randomly stutter only a few times and its completely random and usually goes away but check engine light doesn't usually come on while it does this. But I do have a randomly occurring check engine light any idea what this could be? And only reason I havnt gotten the check engine light checked is because i'd have to go to dealer Thank you for your time

I have a 93 buick lesabre 130, 00miles 3.8 engine and it will not start. I have changed the gas tank thinking it might be the fuel pump still don't start. It does on the other hand keep killing batteries, but the alternator is still good because I had it tested at advance auto. Anybody got any other ideas?

Car has been sitting for years. I changed the battery the spark plugs, new fuel pump and filter and air filter. I am still getting no start but it will crank.

Okay, I have spark and gas in lines but seems like too much gas came out fuel regulator cap with pin.
