I have a 91 dodge dakota. Drove it one day, 2 days later went out to start it and all it would do is turn over. Will not fire. I have replaced the distributor pick up and the map sensor. I have tested pretty much everything on the truck that would make it do that. It does not have a CPS. I'm frustrated and out of ideas. No spark at the plugs at all. Please can someone help me. I even poured some gas directly into the engine and it wouldn't even pop. I'm at my wits end. Checked all the fuses and relays.
1991 without an ECM unit is strange unless you have an older version of the engine installed
you say it has a mass air flow sensor but no CPS( crank position sensor )so that indicates that the spark timing is generated in the pick up in the distributor body amplified by the coil and then distributed out to the plugs
no spark at the plugs will necessitate checking the rotor button is turning, the distributor cap has not track marks to ground the spark out or that the coil is in effect operational
check for 12 volts at the coil terminal while trying to start and 7.5 volts at the coil when the key is in the run position
you could have a problem ignition switch or blown fuse for the ignition circuit
