has spark and fuel, wont start.
okay everybody, i have changed the balast resistor, the coil, tried gapping the magnetic pickup. i lost spark from the plugs (coming out of distributor) but i have spark going in from the coil. would this mean that the external electronic box went bad, or the inside of the distributor.
it has new cap and rotor, plugs and wires. i am stumped.
STOP THROWING PARTS at the problem, and start using your head
With electronic ignition, it is a "little" difficult to create a flow chart but generally:
The reluctor and pickup must be in good shape, I.E. the reluctor star must not be chewed up from hitting the pickup. Additionally, the gap cannot be too large. There is some evidence, over on other "places" that maybe some of the reluctors are losing magnetism or otherwise going bad.
GAP THE RELUCTOR carefully, then take a digi meter on AC volts and crank the engine, see if it puts out about 1V AC (AC volts)
You HAD spark at least once, so this should mean that PROBABLY the ballast, the coil, and the box, are all OK
Pull the coil wire FROM THE COIL. Take a clip lead or test lamp and GRO
UND the clip, crank the engine WITH THE KEY (need a helper) and stick the probe of your clip near the coil tower. You should get a nice blue "rythmic' spark as the engine cranks.
If so, you have a bad coil wire, rotor, wires, or cap
If not, then you still have a problem with the reluctor/ pickup, the box, the coil, OR THE SUPPLY VOLTAGE
Probably the next thing to do before we go any further is find out
"do you have the older 5 pin ECU"
or "do you have the newer 4 pin ECU?"
