2003 Saturn cranks but no start have good spark have fuel to rail changed ecs and ecs when I hold throttle to floor it will want to fire any idea its L200 with a 2.2

SOURCE: Engine cranks but will not fire.

check to see if you are getting a spark from the plugs. Just pull the plug and connect it back to plug wire. Then with gloves ground of that plug at the threds. Have someone try to start it only allowing 3-4 repatisions, and see if you have a spark. If you dont have a spark, then it would be eaither be the sparkplugs, plug wiers, or your coil is bad.

SOURCE: replaced alternator, now car won't start

disconnecting the battery on an alternator is a no no. that was how they used to ck generators but an alternator can be damaged with no load in the circuit. Try changing out your MAF sensor. 1st sensor coming out of the air cleaner. good luck.

SOURCE: 2005 saturn ion 2. Will not start. Engine will

the first thing to do is scan the computer for codes,also when the module was installed did you clean the mounting area good? the next thing i would look at would be the crank sensor, also theres a reprogram on these cars,the dealer needs to install or update a computer progranm on some of these, you would have to call with the vin #, this doesnt affect your nostart condition, its just something you should have done,

SOURCE: car cranks but no start. no spark. crank sensor

Spark could be its only problem, you say the ignition module is okay? Are you talking about the ignition coil, mounted at the end of the cylinder head? That is not the ignition module, the module is located on the left front fenderwell in front of the strut tower, small black rectangular shaped box about a half-inch thick. Have you checked the timing belt? Hope this is helpful, let me know.

SOURCE: I have a 2002 Oldsmobile

im pretty sure its your timing belt
