Hello

Ok if it won't start then I'd begin by locating the crank speed sensor on the front of the engine as this is the primary sensor and with no signal or a corrupted signal will result in a no start

unplug it and use compressed air to blow out both sides of the connector plug

do the same for the MAF meter connector and the MAP ( pressure) sensor on the manifold

these are all critical to engine control
