1995 blazer no start
hi all. i have replaced fuel pump due to only 10 psi of pressure. replaced coil and ignition control module. cap, wires, plugs, and rotor also have been changed. i have 12v going to the coil and no spark coming from the coil could the camshaft position sensor keep the coil from firing?

so the crankshaft position sensor will keep the coil from firing?
ok i put in a new crank sensor and cam sensor still no spark coming from coil. anything else i should look at?

original icm tested bad at autoparts store put new one on still no spark took icm off and had it tested tested good tested original coil with ohm meter across primary and secondary terminals out resistance across primary high replaced with new one put in new plugs, cap, rotor, and wires truck has been sitting for three years. was looking at the crank position sensor wires from behind ac compressorand traced it down to sensor and red wire had about a 2" section where it had been split and a second peice of green wire jumped between it took the cmp sensor harness from behind the ac compressor loose and from sensor cleaned it up and crimped the wires back together. the connector to the sensor and the sensor plug were full of oil from what looks to be a previous oil leak so i figured to replace the sensor because of it being ground out from bare wire or the oil in the connection messing it up

i think i am getting good ground i took the connector to the coil off and put my meter on it and get 12.4v with key on and 11.4 v while cranking. i am pulling my hair out trying to figure it out but still getting no spark from coil.
