Ill give u the run down, it cranks fine, fuel pump is working, it has spark also it has injector plus but here it where it gets odd as the injector pluse is strong for the first couple revolutions then it fades to dim but never stops. t-belt isn't broken also pulged in the scanned check to see if i am losing crank rpms but nope its around 230 cranking rpm.

put throttle about 2/3 ways in crank and crank and crank and crank
make sure its not flooded out, also pull a couple plugs and see if there are fuel on the end. Sounds like a flooded motor to me. (I just went through this on mine) What kind of plugs is he running?

Flooded perhaps. Try the starting fluid trick.. that'll tell you if it's getting fuel or not... Spray the Starting fluid in the air intake while cranking the car.. does it try? If it runs on starting fluid for a few seconds, then pukes out, it's an easy one.. No fuel.

plugs are new (ap 5144), very little fuel on them. the only issue i come with the injector pulse is strong at first then gets weaker as u continue to crank. crank trigger must be working as i am reading rpm signal with scanner.

2/3 throttle crank and crank, still thinking its flooded. id crank for a bit and try dry plugs if you have them. Nothing indicates it being delivery espically if there is a small amount of fuel on the plug. Also check wires and distributorship. But sound likes flooding to me.. and the more you crank weaker it will get, your draining the battery :)

I'd love to tell you what we used to do to lawnmowers when they'd flood, but some genius would try it... and burn they eyebrows off.

oh what the hell. I suggest this only for a flooded 1 cyl lawnmower motor...

Get a blow torch.. take out the plug out.. put the flame by the hole.. turn over motor at a moderate speed and watch it shoot flames... put in spark plug, don't choke.. just start it... Runs now. Don't do this to your car...

Its not flooded forsure as very little fuel is on the plugs, plus i did pull them all and cleaned 'em off.
is there an easy way to check fuel pressure and what psi should it be at?
thanks again for your help.
