[enen1516]

my friend has 2001 s10 xtreme 4 cl 2.2l ,,,due to engine block crack he decide to replace the engine,,, he got complete engine from another s10 who had an accident from back of truck,, so that egine was clean of damache,,,,

Im a bus and truck mechanic so i help him to replace the engine,,,originaly hes car was runing ok,,

after replaced the complete engine,,the engine wont start!!! here is some information"

security light goes on for 2-3 seg them off while the ing sw its on
No engine codes
fuel pressure 65 psi in injector block when crank
i have spark in spark plugs,,
i tryed a shot of starter fluid, i did start but it when off like no gas

check in schematic how the injector arnes is ,, found injectors need to have 12v and groung are controled by ecm or ecu dont know how is in cars,
injectors does have 12 v ,,,i dont have an ossiloscope to check if a have a pulse from ecm to injectors grounds ,,

i found i have 2 crack sensors ,,one is for rhe spark plug module and the otherone for ecm,,i replaced the one for the ecm ,,same thing,,the other sensor is if unpluged them i dont have spark,, so thats not the one,,

i have experince in diesel engines but not in cars ,,i have some cuestions..
what the ecm needs to recive in order to fire rhe injectors?
why no engine dodes?
it is something like secuirity sistem?
i know that before i swap the engine ,, it was working ,, i check and doble check the all conectors engine grounds,, ,,any idea to what to do next?

Are the spark plugs wet or dry on end?
Will it start with a shot of carb cleaner?
If so it is a fuel problem.
I would check for injector pulse.
The parts place should have a injector pulse light.
If security light comes on with key on and goes off that end is usually good.
but does it have a aftermarket anti theft or remote start?

You are welcome and thanks for posting back with what you found.
You might to want to look around for what caused them to plug up.
Rusty lines or bad fuel filter or anything else.

Good luck
