Car won't start?

Pcm's have to be programmed to the vehicle by vin number
you can change it but it will have to be reprogrammed.

You can always try another pcm it might work but it might be worse

Is it fuel or spark !
Check if you have spark at the coil
if so and fuel ok
check or replace plugs
also if no spark check and or replace crank sensor
let me know
check fuel and spark

Does it have spark?Is it flooded?Have you tried holding your gas pedal all the way to the floor while cranking to start it?In order to make sure you have enough fuel pressure to start and run you will have to hook up a fuel pressure gauge and see what the actual fuel pressure is.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem,Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

Do below to determine whether it's fuel or spark problem:

Cranks but no start condition:

Hi first we need to check fuel pressure at fuel rail while the car will not start. You also need to check for spark when it won, t start most likely one of these two things are missing when it won, t start after we determine this we can help you diagnose the failing part let me know thanks billymac

Hi john sounds like the crank sensor has failed. This part is behind the crank pulley and is fired by the fireing ring on the crank pulley. Care must be taken when replaceing. As to not damage the aluminum rings. Another possibility is the ign module. This is mounted under the coils. There are technical ways of testing these parts but special tools and training are needed. The module you can remove and a auto store can test it. The crank sensor can be tested with a dvm. Be sure and check all fuses first. Thanks billymac
