It ran before I changed the head. I am getting spark, but it just cranks. Won't even fire when I pour fuel in to the intake. I am thinking it might be out of time, but how do I get it back in time?

Put the engine no.1 piston on its compression stroke and align cam and crank markings as per the repair manual, make sure the rotor is pointing to no.1 cap tower

My 1986 Suzuki samurai engine will turn over but won't start. Was driving when it just died and now won't start again since. Replaced ignition coil still nothing different.

Hello,

It sounds like you lost the timing belt which is common with this car. Here is a diagram below so you can double check the marks. We can also check the compression test to confirm the failure or remove the distributor rotor to see if it stays still when the engine is cranked over.

Check out the diagrams (Below)

Please let us know what happens.

Cheers, Ken

Motor cranks right up and runs great. But will not recrank up when the motor is warm. We have to wait till the motor is real cold to recrank. What could be the answer?

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
