Hi, my name is Nacho, have problem to start engine,
1º check TOP cyl 1, and mark poly and after remove sensor vr, and count trigger.
and put result in crankshaft trigger,
file
check to light gun , timming, and de mark is correct. the engine with starte have light gun its working but when engine starting up rpm, not have more spark or light gun.
You have to put #1 cylinder on TDC.
I see that you think that you’ve done that. However, it is possible to put #3 up and think it is #1. You can verify that the engine is on #1 TDC by observing the valves, doing a leak down test or by simply placing a makeshift stopper into the #1 spark plug tube and ensuring that it pops out while you are turning it over to what you think is #1 TDC. I like to make a stopper for this with a used set of latex gloves. Roll one hand into the thumb of the other hand and then ball it up tightly by folding it all into one of the remaining fingers.
Anyway, after you are sure that you’re on #1 TDC, you can pull the VR sensor and roll the engine backwards (anti-clockwise) until you see the gap. 360° - (How many ever degrees you turn it anti-clockwise) is the trigger angle. You may need to invert the output depending on how you have your VR sensor wired.
Once you do this, you can use the scope function to get a trace for the cam trigger. My B6304T4 is “longer than factor” but I am nearly certain that you have a completely different trigger wheel.
