Engine wont start

Should not be the case except for the rpm which might be affected. Replace the coil and test if others go away.

You're welcome.

Good luck

Pick your symptoms:

Cranks but no start condition:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing
belt/chain.

No crank at all/nothing/nada:

Could be the starter, starter relay, park and neutral switch and ignition switch assuming the battery and connections are good.

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

Is engine a 7M-GE or 7M-GTE?

Check for voltage on igniter terminal 1 and in crank terminal 3 & 4. Check coil positive term. For voltage. Check neg. With test light crank does test light flash?If no possible ignniter or pick up coil in dist. If yes test coil Primary should be.2-.3 ohms, secondary 9K -12.5K. If not replace coil

Could be a bad starter/solenoid. Check for 12 volts at the small wire on the starter with key in crank position. If it has power then the starter needs to be replaced. If none, then get back to me and we will figure out where it stops

Check the fuel pressure

If your losing the holding pressure from the fuel pump it will do that prolong starting when engine is hot.
