My sons put a running engine out of a 2001 rio in the 2002. The engine turns over but will not fire. It does backfire out through the intake when you release the ign key from the start position like mopars used to in the old days when the control module was bad. Found one bad fuse under the dash, #15, replaced the computer, crank sensor, and air flow sensor. The radio was removed when I bought the car. Got the response. It is to generic to be much good. Whoever replied didn't read the details very close. I was expecting some detailed answers to the SPECIFIC problems I'm having with the Rio. Some answers don't even pertain to this car! (Cam sensors?) I wasted the $10!

Hi Randy,

Thank you for the donation.

Here are possible causes and what to check. The misfiring indicates a possible fault with the ignition timing and that can mean the timing belts is off position.

CRANKS NORMALLY BUT WILL NOT START

"� Check for strong spark.
"� Check fuel pump operation.
"� Check fuel injector operation.
"� Check fuel system pressure.
"� Check spark plug condition.
"� Check timing belt condition and alignment.
"� Check engine compression.
"� Check Camshaft Position (CMP) sensor.
"� Check Crankshaft Position (CKP) sensor.
"� Check voltages of Mass Airflow (MAF) sensor, Throttle Position (TP) sensor, ignition coils and Engine Coolant Temperature (ECT) sensor at Engine Control Module (ECM).
"� Check for contaminated MAF sensor.
"� Check intake air leak.
"� Check Engine Control Module (ECM) power and grounds.
"� If no start after engine is warmed up, disconnect ECT and check if engine starts.
