Q: Pcm ecu car won't start

asked by on

Replaced pcm and the car started and worked just fine for about a week, came home and parked the car, the next day the car wouldn't start. Called a mechanic he said the coil ignition wasn't reading from the computer. I called the place I got the pcm from they said it was my ecu, replaced my ecu now my car still will not start. The batteries fine the started good. I don't have much money to get it towed somewhere.

My car has 155000 miles.
My car has an automatic transmission.

Assuming the ECM is still working enough to report problems, getting any problem codes out of the system with a code reader is your best clue at this point - whether the Check Engine Light is illuminated or not.

If the engine will turn over - does it have spark at the spark plugs? If so, does spritzing starter fluid while starting get the engine to start briefly? Simply narrowing your search with codes and fuel/spark information goes a long way to getting you back on the road.

If you need help with this, I would recommend having your no start condition diagnosed by YourMechanic to inspect this problem, get an accurate assessment of damage, and a cost estimate for repairs. YourMechanic.com can dispatch a mobile, professional mechanic to your location for this repair.
