try checking crankshaft sensor mine was bad on my 97 Saturn cost $12.00
I would replace the ignition module in the distributor.
The ignition module that is in the distributor is probley bad.
Bad coil? Bad distributor cap? Bad distributor rotor?
it does not run smoothly and not all plugs fire when supposed to Addition to above: No spark or intermittent spark, a problem that was fairly common back when distributors had vacuum advances was that one of the wires going to the pickup coil (pole piece) would break from the back and forth movement of the pickup as the vacuum advance would move it to control the timing, symptoms would be no start or that it would start and when you put a load on the engine and the vacuum dropped the vacuum advance would start to move the pickup coil, the broken wire would open the circuit and the spark would die.To check this problem was fairly simple by removing the cap & rotor and tugging lightly on the wires where they go into the pickup coil/pole piece, if one of the wires was broken you could see it and knew you had to replace the pickup coil which GM called a pole piece (magnetic pickup coil and pole piece are the same thing).
Not bled properly or not adjusted properly.
The only time I've seen cracked spark plugs was putting them in or taking them out with the socket not perfectly straight.
Could be spark in the motor, or the distributor and rotor need to be replaced.
Ok, I have figured it out. The coil is putting off what looks to be a good spark, but It is not strong enough to go through the gap between the cap and rotor to get back to the wires. I replaced it and it works!!
Out of time or spark plug wires installed incorrectly. The distributor may be worn out.
The spark plug gap on a 1989 Toyota pickup with a 3.0 liter V6 engine should be set at .032 inches. The best spark plug for this vehicle would be an iridium plug.
I have an 89 Ranger with the 2.9L, was driving on the highway and it just quit. I thought it was probably the timing chain, had it towed to a shop and he checked fuel pressure which was normal, found no spark condition. He tested the ignition coil, pickup coil, module and wiring for faults. Failure traced to the ignition control module. He also replaced the distributor cap, rotor, and coil wire. If you have a no spark condition I would recheck all these because I think if it is a broken timing chain you would still have spark. The ignition control module is at the base of the distributor cap. Assuming your ignition coil and ignition control module are good, try the pickup coil. Stay with the ignition system until you get spark. i have the same problem with my 88 ranger changed distributor, rotor button, ignition coil, and tfi module, still no spark. If it is the timing chain it will not spark.
Usually if the pickup goes it won't start. Year, Make, Model, Engine size would help here. Module & coil are popular also. When does it stall? Hot? cold? Idle?
