Engine wont start
Sounds like a fuel or spark problem. Check your fuses first. If it is not a fuse you need to determine if you have enough spark and enough fuel arriving at the spark. First pull out your number one spark plug and check the spark and gap to rule out the need of new (or cleaning of old) spark plugs and/or ignition system (i.e. ignition wires (you will need a spark plug gapping tool for this)). If that has been ruled out then remove the injector rails and try a quick turn of the key to determine if they are delivering fuel by noticing if the fuel squirts out. If you have little or no fuel coming out (it should squirt hard) of they injectors you will then need to determine where the stoppage is (whether you need injectors, fuel filter, fuel pumper or any combination including all of the above). If you determine it is a fuel problem check the filter if it is blocked or dirty replace it. If it is not the filter then change the pump. If it still does not work you need to clean or replace the injectors. Replacing is suggested, the fuel injector cleaners are not good for other components of the vehicle and also are not good for the environment. Of course I write this under the assumption you have fuel in the tank.
Alternator and battery are new but battery goes dead after a few days; alternator tests ok as well as battery; been to 3 shops to be told that everything is ok; i need help
If the battery is loosing charge after a few days then there is a current draw that is not being accounted for .Remove the earth wire from the battery and place an ammeter in the circuit between the battery and the earth wire and read any current flow. If it is low say 2 amps you are looking at interior lights-glove box light-boot light etc If it is higher Fuel pump- head light module or relays-radio amps-alternator. If you have nothing then it will be the battery or the drive belt to the alternator is not adjusted properly or is incorrect if "v" belt and it is slipping under load. Have the battery load tested as just putting a multi meter across the terminals will not indicate failing cells. Have the out put of the alternator checked as it is possible for new alternators to be faulty and not charging more than 12 volts( Has to be 13.5 minimum)
I have a 1967 plymoth valant slant 6 I did a tune
Recheck your points gap - it should be .020 (sometimes when the gap is set initially, it changes slightly when the points retaining screw is tightened down). If you have a dwell meter, check the dwell (.040) and CAREFULLY re-tighten the screw. Now for a silly question, did you remember to put on the rotor? Good luck.
Car starts but turns off after a 10 min or so.
This definitely sounds like a fuel pump/filter issue. Good news if it's the filter, it's only about 10 dollars to buy a new one and about 5 minutes labor, including jacking up your car.
Fuel pumps cant be a pain in the arse at times, others are fairly easy. Best way to determine if it's the fuel pump, run over to Canadian tire and pick up an ohms meter. Test the fuel pump that way.
Service engine soon light
Not exactly.The fuel pump would not cause a trouble code, but low fuel pressure could. Have you checked fuel pressure and the computer for trouble codes ?
Speed vibrations and floorboard knocking in 1992
60mph speed vibrations: have your tires checked. They may be out of balance. One way to tell is to run your hand flat over the tread surface as you go around the tire. other than the space between the treads, you should feel a relatively smooth tire. If you notice raised treads, lumpiness or uneveness in treads then you may need to change tire. Have suspension checked. As for the floor board knock, have your motor and transmission mounts checked.
