I have a 95 toyota corolla sedan. Put in new rebuilt engine, fired it up, it ran for 5 seconds, then quit...now i have no spark? what is it? I changed the igniter, still no spark

i would first check the timing and if that does not fit i would take the cover back off and look at the belt for a bad or missing tooth

I respectfully disagree.
A P-0300 will NOT be set in a Corolla by a dirty fuel filter.
Replacing the fuel filter could be a very costly operation, as I have observed that the fuel line threads that connect to the fuel filter easuily get damaged when removing the fuel filter.
In short, don't replace the filter until you are SURE that it is the culpit.
In this case, the fuel filter is NOT the culprit..
Save your money; and your time.
Additionally, premium fuel does not clean fuel injectors. That expense would be a waste of money. The engine will actually run WORSE on premium fuel; the engine is NOT designed to run on premium. 87 or 89 (better choice/89) is the grade to use.
If you really want to track down the P-0300 code, which is a multiple/random cylinder misfire, I would look at the quality of the fuel in the car; ie water in the gas. Second, I would remove the plugs and examine them closely. A worn center electrode will also set the P-0300 code, as will bad/weak plug wires (over 5 years old).
Please feel free to contact me back if you need further assistance. Thanks for choosing FixYa for assistance.

At the cost of the igniter i recommend checking your pickup coil.( The 2 wire sensor in side of your distributor. The The igniter will not allow the coil to fire with out reference form the pickup coil. Coil has primary and secondary resistances. when the primary coil powers up and then pulses off, this cause a high voltage due to magnetic degeneration. Check the coils primary and secondary resitances along with the air gap in the pickup coil, and also check the resitances on the pickup coil. If i am right your igniter will be okay.Get a good manual for you truck, It will save you money down the road.
Toyota does not have at test proseger for the ingiter.
Also check the wires in between the pickup coil and the igniter.
I hope this helped.
