You need to check fuel filter and fuel pressure. A fuel pressure gauge is about a $50 item. You can listen for the fuel pump by just turning the key to the Run position w/o starting. It's in the tank and you should be able to hear it run for a short period of time as it builds up pressure to about 50-60 psi. It should hold that pressure for a period of time after you turn the key off.

2005 Chrysler 300 C. Battery went completley dead. Jump it . It holds a charge. Now check engine light on. Runs rough multiple missfires. Replaced battery. Ran good for 10 miles. Check engine on again....


Fill up your gas tank and ad a bottle of Lucas gas treatment/lube to the tank, be sure it's the treatment in a little clear bottle and not injector cleaner. After you've added the gas and treatment drive the car, with the head, driving lights, radio, heater, etc. all turned off. It may take ten miles or more but the check engine should go off and car will run normal. NOTE: Never jump start your car or use it to jump someone else's without referring to your owners Manuel.

Hesitating when going a constant speed.. seems to be worse when fuel tank is below 1/2 and going up hill


may need to replace fuel filter.or could be an idle control sensor going bad. try running lucas fuel treatment through it 1st, it may only be a fuel injector clogging up, are you burning ethanol gas? i would go with fueling with good gas and adding the lucas fuel treatment !st before you do anything else. if that does'nt work then replace the fuel filter, if not that then i would replace the idle control sensor.hope this is some help to you!!

dirty fuel fiter, yes. But also certain models require mid or premium grade gasoline. regular unleaded has more water in it than premium. Hense the pinging. When was the last time you have your fuel injectors cleaned. Try adding a gas treatment like STP gas treatment/fuel injector cleaner, that should help. If it continues then its the fuel filter or the fuel pump is also going out.

Changed spark plugs in 97 buick lasabre and now it cranks and runs, but white smoke coming out. Is that blown head gaskets? Does it have anything to do with the fuel pump my mechanic put on 3 weeks ago???


You need to check the oil with the dipstick (wipe in down a few times) to see if it looks like a chockalate milk shake. If coolent has made its way into the oil you have blown head gasket. The fuel pump which is usually in the gas tank in most gm vehicles would not cause white smoke, if it failed you car would not start because your engine would not get any gas to the injectors

Transmission shifts irratic when cold


If fluid level is good, the hydraulic value of the trans fluid maybe low or worn. If fluid is old or burnt, (never been changed, or high mileage,) sometimes not a good idea to flush. Highly suggest LUCAS (ONLY) Transmission Treatment, carefully read instructions on bottle. Transmission replacement is expensive, following maintance will prove rewarding! If you wait to long to flush trans your worse off!!! Hopefully helpful!!!!

2004 GMC sierra cylinder miss fire code


Have you put new sparks plugs in it. If you havent I would try them first. Only run the ac delco plugs listed for the truck. I have had many people come threw the shop with misfiring and trucks running like **** and come to find out they put bosch or ngk plugs in it. Your manual says there good for 100,000 miles but there really only good for about 75,000 or so. Also run some lucas fuel treatment or b12 chemtool. both you ad straight to the gas tank. If it calls for one can for 20 gallons buy two and double the treatment it wont hurt you engine.
