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
