i have an 86 mazda b2000 and it won't start. the car tries to turn over, but won't actually ignite and "come to life" as it were.

i've replaced the timing belt and gotten it to the perfect spot it should be at, replaced all the spark plugs, spark plug cables, distributor and cap, still nothing. any suggestions on what to do next and what could be my problem?

Check fuel pressure. Try spraying carb cleaner in the throttle body, if it starts, you have a fuel issue.

I checked by spraying that in there and still dont get anything. Whats the next step?

Any list of what and how to troubleshoot everything would be great too. I just dont get why its not working.

Heres a link to a very helpful, informative site...

Since there is no fuel issue likely, suspect a lack of fire/spark. In this case, I'd think either the ICM Ignition Control Module or a bad coil.
