My 89' S-10 will not start.?

Question

When I turn the key the engin turns, but fails to start. Every so often it acks like it will start but dosen't. So I changed the plugs, and it worked for a week or two. At that point I changed the plug wires, cap, rotor button and checked the fuses. I made shure to put every thing back together the way it had came off. it started and I drove to work and back, and now ti dosn't start at all. At this point I take the distributer cap back off inspect it put it back on.... nothing. My next step is checking for fuel and spark. it's getting fuel and spark, how ever the spark from the coil is white, and the spar from the plugs are reddish orange. I am at a loss of what to do now.

Answer 1

Sounds like a weak battery although it could be a bad ground or loose connection.Make sure the condensor is secured well and check for loose ground from battery to engine connection.Could also be a bad ignition module in the distributor.Correct all leaking vacuum hoses.If it was dying at stop signs before you will need to rebuild the carburetor.Make sure alternator pully belt is tensioned properly.

Answer 2

Try replacing the coil--spark at the plugs should be blueish-white---sounds like the coil is weak, probably from age. Since you have new wires, I would say that there's not high resistance in the wires and make sure plugs are gapped properly. Try starting it by having someone pour a little gas down the carb while cranking it to see if it fires up---could be low fuel pressure also. Filter changed recently? Pump worn out?

Answer 3

I have been working on cars for 15 yrs now and that sounds like your starter babe but also have you battery and alternator check too

Answer 4

i think it can be the alternator or starter.... you should take it out and go to schucks or something and they can test if for you.
