It overheated. It started once after that. Now won’t start. Replaced spark plugs, camshaft sensor, crankshaft sensor, oil filter, oil. Battery isn’t the greatest, four years old, but it won’t start with a jump or anything. I originally had a code for the number 7 misfiring. The spark plug was bad. I changed all of them then. Oil didn’t look like it had any coolant in it. I’m stumped. Please help.

Hello,

Okay, a vehicle only needs three things to start. 1) Spark(delivered at the proper time 2) Fuel 3) Compression. Since your vehicle overheated I'm concerned with the latter of the three, compression. I have included a few links below for you to go to:

Please go through these guides and get back to us with what you are able to find out.

Thanks,
