Batteries were dead, engine rotates freely, but will not start has fuel in tank.


Basic two things to make it go.
Spark at the plugs
Fuel in the jugs.

Try priming it with a couple of spoonfulls of gas in the carb.
If it doesn't bark, pull a plug and check for spark.

Once you isolate the problem, the solution is easy.
Keep me informed.

Car been in the garage for a while and has been start for several years and will not start. What can i do to get this baby started?


Go through the steps, pull the air filter out and shake out the mouse nests, pull the spark plugs out and pump in some fresh fuel, make sure you are getting spark before messing with the fuel, Then give a go, If no spark, you will need to check the coils, the wires, the plugs, the computer, also has an ignitor somewhere I think. If it won't pump gas, check the oil, You should have found something by now. Hope this helps.

My 91 Subaru Legacy shakes when I am driving, engine runs fine, could it be a engine mount or something.


some of the problems that makes the engine shake are...
spark plugs,engine mount,or one or more cylinders are not functioning.
lets just hope its a spark plug...
usually if you clean your engine...some water gets to the spark plug and then the engine starts shaking...so check if the spark plugs are filled with oil or water...or anything else...or it might just be that it got warned out...good luck!

It sounds like your spark plugs or leads are not working.

When did you last have them changed? Spark plugs should be replaced every 20,000kms (12500miles) and the leads about every 60,000 kms (40,000 miles).

If there is any problem with these your car will not run smoothly while under load.

Also you should check your distributor cap and see if it is cracked or if there is any carbon build up on the inside of the pins.

the distributor cap should come off with 4 10 mil bolts and should be located to the left of the engine block.

Undo the 4 bolts and pull the cap off (make sure you have disconnected the leads (and checked which order they are plugged in - they need to go back on the same way). Check the 4 pins on the inside - if there is carbon build up on the pins get a flathead screw driver (or a knife) and scrap away the carbon and a bit of the end finish on the pins. Put it all back together and check how the car runs.

I have a 1991 740 volvo, was driving down he street and it died,after i pulled over it wouldn't start


Check if you still getting fuel and sparks, two items need to keep the car running. Check fuses and fuel pump relay, if needing new relays go to the junk yard and get couple of them for nothing. Checking making sure you getting fuel and fuel pump working properly, unplug the the main coil wire to distributor so the car wont start we just want the engine just to turn over. under the hood, locate fuel filter, disconnect the line to or from it, wrap the bottom of the hose with old clothe firmly and to remember to point the house downward away from your face so it wont splash at you. and have a friend turn ignition over just like starting, see if the fuel come out with good pressure. if fuses and relay check out, your crank sensor may be bad, being 91' strong possibility. crank sensor send info to computer telling to send fuel to your injectors. For sparks, make sure you plug the main wire to distributor back. pull one plug wire and get spare plug, plug it and ground the plug and have a friend turn the engine over and see if you getting sparks, do not touch the plug, big shock. No sparks, check the coil if you getting 12v, if yes, than your cam sensor is faulty. The cam sensor work just like the crank sensor but telling the computer to send sparks to the distributor. Common for older European cars, crank and cam sensor tend to become faulty after years of service due to age and heat abuse.

Change your fuel filter, and run a can of "Seafoam" in your next tank.....
Check your spark plug condition and connections, as well as your distributor cap
