If i pushed down on it, it would sputter worse. Quote Link to comment

fourfiveten Posted February 5, 2011 Report Share Posted February 5, 2011 Changed the leaking inline pump (not stock) in my five ten, and changed the clogged fuel filter (that killed the pump). runs good now. Fuel filter's cheap and easy. Quote Link to comment
bananahamuck Posted February 5, 2011 Report Share Posted February 5, 2011 Check to make sure vacuum advance is working properly.Take cap off them suck on hose does advance plate rotate a little bit? Quote Link to comment
80datson Posted February 5, 2011 Author Report Share Posted February 5, 2011 i changed the fuel filter maby like 2 years ago maby longer. would i need a new one? Quote Link to comment
Skib Posted February 5, 2011 Report Share Posted February 5, 2011 i changed the fuel filter maby like 2 years ago maby longer. would i need a new one? :o whens the last time you did the rest of the regular maintenance? (spark plugs, wires, cap, rotor, points, oil change, checking valve clearances, ect) Quote Link to comment
metalmonkey47 Posted February 5, 2011 Report Share Posted February 5, 2011 :o whens the last time you did the rest of the regular maintenance? (spark plugs, wires, cap, rotor, points, oil change, checking valve clearances, ect) What he said!! You have a lot of maintinence that you need to do if you haven't been on top of it man. You got an electronic ignition, so no points to deal with. Check ignition timing. Quote Link to comment
wayno Posted February 5, 2011 Report Share Posted February 5, 2011 Sometimes we get into the, "if it ain't broke, don't fix it" mode, I go farther, if it still moves, keep driving it. If it won't start, it's time to fix it. :lol: :lol: :lol: Quote Link to comment
datzenmike Posted February 5, 2011 Report Share Posted February 5, 2011 The fuel filter is past due for changing so do that first. No harm done if this doesn't help. They are cheap and easy to change. Quote Link to comment

80datson Posted February 6, 2011 Author Report Share Posted February 6, 2011 well i changed the spark plugs and wires and rotor and cap about 3 or 2 years ago. so i will be going to autozone and picking up new ones. also i will get some carb cleanr and is there a way to test or know if the ignition coil is bad? also im thinkin of putting a bigger battery looks like i have quite a bit of room for one Quote Link to comment
datzenmike Posted February 6, 2011 Report Share Posted February 6, 2011 Battery won't fix this nor a new coil. A Datsun will run with a motorcycle battery in it. Same with the coil... if it runs it's working. Spend the money on new wires cap and rotor. These are high wear items that just wear out or their performance degrades until you have a running problem. Again they are likely past due for replacement so no harm done. Quote Link to comment
banzai510(hainz) Posted February 6, 2011 Report Share Posted February 6, 2011 well i changed the spark plugs and wires and rotor and cap about 3 or 2 years ago Be honest they propably still good. unless you bought the cheapest shit on the planet. Buy NGK wire sets and plugs. dizzy cap, look under for aything obvious and clean contack & rotor.I been using the same dizy cap for 6 yrs or more. I would ck for dizzy shaft wear, if if it wiggles. as for the bigger battery statment means car runs better with heat, lights off. if not then it cant be a bigger battery as your alternator would load down then runs off the battery till it dies. If car starts up fine then battery is Ok. Maybe ck the voltage at the battery then load it down with the lights and heater at say 2k RPM. if it still above 12.5volts at 2000 rpm I say its OK. have you put a timming light on it?try that first. Pumpkin 210 on here is good with A series motors PM him Quote Link to comment

80datson Posted February 6, 2011 Author Report Share Posted February 6, 2011 ive decided to clean the fuel pump aswell. is there a write up for that? Quote Link to comment
ggzilla Posted February 6, 2011 Report Share Posted February 6, 2011 Clean the fuel pump? You might need to replace the fuel filter, but otherwise there is no cleaning needed. You can make a fuel pump look less greasy -- spray with ether (starting fluid) or engine cleaner or my favorite (carb cleaner) on it and scrub it with a toothbrush. My distributor cap is over 10 years old and still going strong. Plugs are 4-years and still good. Just regap em once a year. The Matchbox keeps the plugs in good shape. Your 1980 should have a Matchbox ignition too. Quote Link to comment
80datson Posted February 6, 2011 Author Report Share Posted February 6, 2011 well i figured it would be a good idea to take it out and clean it cas the same gas has beenn sitting in the car for a long time.. Quote Link to comment
