Have a 87 buick lesabre 3.8 liter motor. Having trouble with it starting. Acts like not enough fuel or spark. Sometimes it takes 3 times cranking on the starter to get it to start. Also when it gets hot...


Please check the following.

Check Spark at the plugs. (all of them)
Fuel filter not clogged.
Choke working properly.
Rev the engine while shooting carb cleaner through all the ports.
pull and clean and check your mixture screws. (Remember to EXACTLY count the turns out and go back in the same). See if this helps. Mike

Why does my 2003 pontiac sunfire lose all power while driving


That can be the symptom of a bad Ignition Control Module, or also a bad crank position sensor. The ICM can be taken off and tested for free at any parts store. The crank sensor circuit can be tested on the car with a multi-meter. Also small motors (like a fuel pump motor) that are starting to fail can sometimes work until they get hot and then stop working until they cool down again.

Next time the car shuts down and won't restart, check for spark on a spark plug wire with the engine cranking over. If you have no spark, suspect the ignition control module or the crank position sensor. If you still have spark, but won't start, check if the fuel pump is putting gas up to the engine.

My 99 buick regal cranks over and starts but has trouble running. If you give it gas to help it through the start up it levels out and runs fine. Fuel pump is good, I've changed spark plugs and wires,


sounds like a stuck open EGR valve to me , take it off of a cool engine and spray some carb cleaner around the seat see if any leaks through to the other side. If it does The valve is bad. Also check out your throttle body for carbon and gumming. W/ engine off spray an appropriate carburator
cleaner into the opening and clean throttle plate and bore with a rag until shiney. put all the air cleaner hoses back together and hold throttle to floor momentarily until engine starts, then rev up half way and release throttle twice quickly, now allow engine to idle idle should be stable and smooth. If not then check for other sources of vaccume leaks.

1987 Ford f150 shuts off and wont start until engine is cooled off


To clarify, you said it runs for 20 min then quits, and it won't start again until it cools off. Have you checked for spark at the plugs and fuel pressure right after it quits running ?
These models have an ignition module attached to the side of the distributor that has a history of failing when hot. The coil and the pickup inside the distributor can fail too. Could also be a relay.

Hello, Car will start until warm then shut off then won't start again until cool then same thing happens over again


As with any no start issue you will need to figure out if you are dealing with a no spark or no fuel problem to proceed. Check the plugs for spark and the fuel pressure the next time it will not start.
Could be a faulty relay, ignition module, coil or other electrical component.
Let us know what you find.

Starting problem


Pressure in the tank is normal, let it sit overnight if possible, turn the key on, but don't start the car, listen for the fuel pump to to on and then shut off this is normal, turn the key all the way off, then do it again, listen for the fuel pump to the same thing on then off, after doing that about three times then start the car like you normally do, if it starts ok, then one of you injector is leaking down or the check valve is bad. If you still have a problem look and see if you have any smoke coming out of the tailpipe. If is kinda blue, it could be your valve seals leaking oil down on your spark plugs. Did the old spark have a white looking ash on them?

On my f150 5.0 it starts good cold but after i drive for awhile maybe 5 miles i shut it off and start it again it is ok.But if i wait 15 min it wont start.you can try but after it cools off it will start...


It could be a spark plug problem..I would remove a few of them to see what they look like. It may not be firing very well when it gets hot, and new spark plugs are never a real bad investment, since they're generally very cheap. Not sure on this, but it's a good place to check.

Car cuts out and stumbles. does not start from warm


Hi,

yes they are linked together I had the same problem and the solution is your coil pack needs replacing there for there is no spark for the spark plugs to the engine thats why the rev counter is moving it the engine cutting out really quickly.

There not expensive I got 1 from a scrap dealer for 20 euro and really easy to install its just 2 bolts and a connection.

The smell off fuel is from when your trying to start it back up the fuel is being pumped into the engine and not being burned
