SOURCE: Engine cranks, won't start

That does not sound good. It seems that you may have broken or worn rings or pistons. You could try timing the engine and see if that is not a problem but I think it is a bad piston and rings.

2004 susuki forenza won't start after i put new head and put in time ,ran good for thirty minutes

Old post but , this answer covers all , of this type symptoms.
new head,
ran for 30 minutes
so does it crank ? ok? if not dont crank, it can start.
so crank is next. (first)
backfiring (true to the air cleaner) usually means TIMING IS way off and sure engines can start with timing way off and then stall and flood out.
nothing new there.
you did not time the engine correctly.

get the FSM on engine. read the pages.
or go to and read that.
for others searching using google, my lil. contribution;

1998 chevy venture won`t start. cranks over pops and backfires, was running great till it shut off when I was driving it. obd says no codes found

unplug the MAF sensor and see if that helps.

I assume you have spark since it is backfiring. Will it start if you use a little carb spray in the throttle body?

If it does than you have a fuel issue. Check fuel pressure. You should see more than 35 psi roughly. If there is no fuel pressure than check for power to the pump (the larger of the two grey wires at the pump). If there is power than the fuel pump would be the first thing I suspected.

Kickback while cranking

I am assuming you have the vortech engine...but regardless it sounds like a fuel pressure regulator problem to me..i can guarantee that it isn't in the starter. Being as it's intermittent I would start by checking all of your vacuum lines and by buying some spray injector/throttle body spray and cleaning your throttle body..make sure that you clean your throttle plate..(the round plate that is in the body that opens w/ accelerator)..use a small brush and make sure you get as much carbon off of the inner and outer bore edges as possible..start there. The vortechs are known for their fuel pressure regulators going out though.
