Two things... did you check power going to the coil? Should be 12v with key 'ON". There are also fuses in system labeled ignition check these. Other thing often overlooked... There is a sensor pickup in the distributor. if no signal coming from there... no spark (just like a set of points) This part is also called a a cam sensor.
Note: if timing chain is worn out of limits, it can give you really wierd symptoms and eventually a no start condition as well.
You probably fixed it by now, but this info may help someone else!!

The crank sensor is a common problem with these jeeps.
The sensor is on the top side of tranny bell housing on the drivers side.

My 91 Dodge Dakota will not start just turns over and over.

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

My 97 grand cherokee cranks but wont start i got fuel pressure and i sprayed starting fluid and changed the cps and still wont start looking for any and all solutions

Did it act like it wanted to start when you did that? You say cps but truthfully that don\'t tell me if its crank or cam? It should have a real distributor and you should check fire from there. Look at and check cap, rotor, and wires and make sure they are on correct If you still have no fire then replace ign coil.... Now.. if it was tring to crank when you sprayed it then listen on how it cranks. If it turns over slow,fast or if it sounds retarded. If any of those occur then check timing and all its componets. Make sure the fire you checking is good spark.. blue or red or both just as long as its fire. If you\'ve replaced the coil and still no fire then prolly gone be a timing chain broken but most of the time engine will turn over a lot faster in this factor. If you\'ve check chain and its good, then a broken cam or crankshaft is obvious. Now... you can dig deep into the whole checking voltage and computer if you like... but my personal experience is this problem has never been PCM or ECM

My 2003 saturn ion will turn over but willnot start

You may have two issues, one with starting and running while the other may be ignition lock cylinder related. You may be able to try using the spare key if you have one otherwise its recommended to have one made by Saturn and try it before determining that its a worn out lock cylinder. Then Saturn may be the best choice to at least configure a new lock cylinder with the original keys to match. The lack of engine firing up may be a simple cps failure.

The engine turning over but never firing up may be related to the crank position sensor (CPS) as long as you don't see the security light flashing in the speedometer or tach. The security light flashing would mean the factory anti-theft deterrent system is preventing engine running by disablng the fuel pump. No fuel pump = no engine run. Determining a faulty cps is by way of observation - the spark from the ignition system is observed. Remove the spark plug wires, noting the firing order carefully, from the coils and have someone crank the engine over so you can watch for expected sparks across the coil towers. A lack of sparks usually means a failed cps as the only other failure would be the ignition module that the two ignition coils mount onto. The cps is mounted behind and above the starter with one 10mm bolt. You can buy it from any auto store stocking it.

My 3.0 ranger cranks but will not start is not getting fire to plugs changed coil pack cps crank senser what else could it be

Sounds to me like a bad control module. The control module controls the order of which the coil pack fires. If that is bad you get no spark. Seems to me that it should have been your second option right after replacing the coil pack.
