Engine won't start

Asked by Apr 30, 2016 at 10:13 AM about the 2004 Suzuki Forenza EX

Question type: Maintenance & Repair

Installed a crate motor in my car and it cranks and
acts like it wants to fire, but will not start and run.
Did compression and fuel pressure checks, and
there is spark to every plug. Is there a "shipping or
freight mode" the computer reverts to when you
disconnect the battery? And if so how do you reset

When the battery is disconnected it will go back to factory presets, this will still allow you to start, run and drive the vehicle as it enters the relearn drive cycle. I suspect something else is wrong, possibly a missed sensor or ground wire. Have you tried just a little starter fluid sprayed in the intake during cranking? If it fires and run briefly then a fuel delivery problem is present, possible plugged injectors from sitting too long, no injector pulse or power.

Did the 2.0 engine come complete with all new control sensors? if not there's your issue. start checking.. read for codes. Try and find an old Suzuki SDT scanner if your a fan of these vehicles
