1994 another Toyota Camry won't start.


Sounds like a timing chain , worst case, Would you say it's turning over almost too freely?? Look under your cap, and turn motor over, the rotor shouldn't turn if the timing chain is gone, but may turn if it jumped it's timing. Then you'll have to have a look under the timing cover . let me know if this helps

Car won't start. Sounds like the engine flooded. Not the starter. Also loses power going uphill and when accelerating.


Check Engine Light flashing when accelerating ,severe engine misfire . Something in the ignition system is breaking down under a load . If the starter engages an spins the engine when you turn the key to start an it doesn't start an run , it has no spark or fuel pressure . If you don't know this or how to diagnose .suggest you take your vehicle to a qualified repair shop . Pull two plug wires off the top of the same coil an crank the engine , if you do not see a spark jump from one coil tower to the other you have an ignition system problem . ignition module or crankshaft position sensor
