My car is actin up!!!!

Buy a new crank sensor from a Mitsubishi dealer. For that sensor always buy OEM parts. More expensive, but 100% reliable.

Any codes? Maybe another sensor has gone bad? MAF?

Crank or cam position sensor more than likely I would say crank position sensor if cam sesor goes out the crank sensor with take over but not other way around

if you dont know anything about cars then take it to a dealer as it will be cheaper in the long run

first the cam sensor shouldn't be upside down from the 95. they both should be with the plug facing down. they 95 CAS has a different plug than the 99 CAS.
the 95 has round pins and the 99 has flat pins.

95-96

--------------------
97-99

-----------------------------
also the 95-96 relays are opposite the 97-99

95-96

------------------------
97-99

---------------------
besides that it could be the ecu. i also have heard of the locating pin on the intake cam shearing off, allowing the gear to turn with the timing belt without the actual camshaft spinning.

your computer is confused

More than likely needs a crank sensor, Try cranking with the crank sensor disconnected, you should not get the dashes in the cluster. The crank sensors take out the communication system of the vehicle

I have a 95 eclipse and had the same problem. Replaced the coil, plugs, wires. I had it taken to 3 garages before I found out. It's a problem with the anti-theft system. I don't have the exact location, but the guy who finally found out the problem said it was under the front bumper. Sorry I can't be more specific, but I know how puzzling the problem is. I spent a good 700 dollars and 4 months on two "I don't know"s and a little under $200 to actually get it fixed.

If it turns over the starter is not the issue. Could be cam ,crank sensor or even fuel pump

is the motor timed right. the cam and crank sensor signals have to be in sync if your too many teeth off it wont start and engine damage could result.

The signs you mention 'putt putt' are normally casued by excessive fuel, something approaching a flooded engine. If you do this with the hood open, you will probably smell raw gasoline.
A cold engine needs an extra shot of fuel to fire off but once warm, it gags on it. I don't know your car so I can't tell you what controls the extra gas for cold starts; it seems to be doing it whether cold or not. I guess I would first check any electronic temperature sensor which could be located in the cooling system or intake or exhaust system. Your new computer is getting the same wrong information as the old one.
