My Neice has an eclipse and it was running fine but the check engine light came on and they took it and had the codes read in it came up as a map sensor and some other intake exhaust sensor. Well they drove the car and a few days later it just dies, I am mechanically inclined and have been employeed as a mechanice but I am not up on all of the snesors and things. The car is getting plenty of fuel but no spark at the plugs, I checked all 4 plugs and nothing. I know it is not commom for both coil packs to go bad at the same time and I know that the map sensor could be bad and the crak position sensor could be bad but I dont want to start replacing sensors till I find the righ one, Any idea where to look or what the most common problem could be? Any help would be apperciated, Thank you in advance for your help

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

Ok, I replaced the map sensor and still nothing, no spark or anything, how do I go about testing the crank sensor and cam sensor? My neice has run ut of money and really needs to get this car fixed. What is mostlikely the problem? And again when it was put on the computer it came up with the mapsensor and and some exhaust sensor, what could that be and could that be the problem? PLEASE any help would be apperciated

Do you have a diagnostic trouble code/s?

The MAP sensor has nothing to do with spark, On the cam and crank sensor you check its resistances it in the repair manual

Check and test the CMH and CPS sensors

NO CAMSHAFT POSITION (CMP) SENSOR SIGNAL AT PCM NOTE:For terminal identification, see TERMINAL IDENTIFICATION in SELF-DIAGNOSTICS section. For circuit and wire color identification, see WIRING DIAGRAMS - 2.0L - NON-TURBO article. Check Camshaft Position (CMP) sensor installation. If CMP sensor is properly installed, go to next step. If CMP sensor is not properly installed, repair as necessary. Disconnect CMP sensor connector. Turn ignition on. Check voltage between ground and CMP sensor connector terminal No. 1. If voltage is 8.5-9.5 volts, go to next step. If voltage is not as specified, go to step 5). Check voltage between ground and CMP sensor connector terminal No. 3. If voltage is 4.8-5.2 volts, go to next step. If voltage is not as specified, go to step 5). Check continuity between ground and CMP sensor connector terminal No. 2. If continuity exists, go to next step. If continuity does not exist, check CMP sensor connector. If CMP sensor connector is okay, replace CMP sensor. Clear DTCs. Road test vehicle to verify repairs. If DTC 01 resets, replace PCM. Check all related connectors and wiring harness between CMP sensor and PCM. If wiring and connectors are okay, replace PCM.

CRANKSHAFT POSITION (CKP) SENSOR REFERENCE SIGNAL AT PCM NOTE:For terminal identification, see TERMINAL IDENTIFICATION in SELF-DIAGNOSTICS section. For circuit and wire color identification, see WIRING DIAGRAMS - 2.0L - NON-TURBO article. Check CKP sensor installation. If CKP sensor is properly installed, go to next step. If CKP sensor is not properly installed, repair as necessary. Disconnect CKP sensor connector. Turn ignition on. Check voltage between ground and CKP sensor connector terminal No. 1. If voltage is 8.5-9.5 volts, go to next step. If voltage is not as specified, go to step 5). Check voltage between ground and CKP sensor connector terminal No. 3. If voltage is 4.8-5.2 volts, go to next step. If voltage is not as specified, go to step 5). Check continuity between ground and CKP sensor connector terminal No. 2. If continuity does not exist, go to step 5). If continuity exists, go to step 6). Check PCM connectors, junction connectors and wiring harness between CKP sensor and PCM. If wiring and connectors are okay, replace PCM. Check CKP sensor connector. If CKP sensor connector is okay, replace CKP sensor. If CKP sensor connector is not okay, repair as necessary. Clear DTCs. Road test vehicle to verify repairs. If DTC 40 resets, replace PCM.

Ok I have replaced the cam shaft senso and still wont start. I guess it is either the crankshaft sensor or the ecm? I cant even find the crank shaft sensor on this car but I just had back surgery so I can get down under it and look up at the crank or harmonic balancer, please any other idea would be apperciated
