Engine Performance problem
1992 Toyota Camry 6 cyl Two Wheel Drive Automatic 150000 miles

It starts good when cold, runs good, but after you drive it for awile and shut it off it is difficult to get it started again. It cranks over ok. If you let it set for a couple of hours it starts ok. What could be causing this? Ron

Do you
have the same problem?

Hi Ron Gogolin, Welcome to 2carpros and TY for the donation

Next time it refuses to start do below to determine if its fuel or spark problem and get back with some results-let me know

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 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, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, 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, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing

Was this
