Have Toyota Questions? Ask a Mechanic for Answers ASAP
When you turn the key to the on position does the yellow check engine light illuminate? Do you have a code reader to check for malfunction codes that may be set in and to control computer?
Can you get To a nearby auto parts store and borrow or rent a code reader or I can recommend a good one for less than $60 that I recommend everyone have in the glovebox it will save you hundreds of dollars in diagnostic fees down the road. Did you check for ignition spark? When it quits running do you still have ignition spark or does the spark quit?
Is this a four-cylinder or V-6 engine?
Okay, let me gather some things together and I will reply with answers to your previous questions and a little more detail on what I'm trying to get you to do. This may take 10 or 15 minutes I'm just finishing up with a job in the shop.
Working on it now.
Click or the link below It is the code reader that I strongly recommend it is relatively inexpensive and will actually give some data list under the live function. As far as your questions previously you cannot change or program the computer or reset it with a code reader on these older ones. You need the code reader to see if there any malfunction codes that would be set in the computer these codes would give us a better idea how to proceed with diagnosing this problem. Your system is designed with three ignition coils and three wires each ignition coil fires two cylinders at the same time one on the compression stroke and one on the exhaust stroke. If you did not get one of the coils plugged back in or damaged one of the wires it will cause the IGT and IGF circuit to shut down which will give you the exact same problem that you're describing. Having a code reader will let us know if those codes are set in the computer. For checking for spark simply remove one of the ignition wires that does not have the coil attached to it place a screwdriver in the end of the wire holding near a ground component have someone crank the engine over and see if spark is coming from the ignition coil wire to ground. Wear insulated gloves so you don't get shocked this should jump about 3/8 inch to ground. If you removed any ground wires on the intake manifold make sure they are clean and tight this will cause the problem that you have also. This is not likely a fuel pressure issue something got disconnected that is computer-related or ignition coil related. Possibly one of the camshaft or crankshaft position sensor connectors double check everything let me know what you find.
Did you recheck all of your electrical connectors? Did you make sure the harness to any of the ignition coils did not get disturbed? When it stops running do you still get spark?
OK the DLC port under the dash is what you need.
