When the check engine light flashes this is a class a misfire. If this is a 1999 you have a spark plug or a spark plug wire bad. Get a tune up done and replace plug wires.

Where is diagnostic connector locationon 1994 toyota base pickup

The check engine light is used to blink out the trouble codes. The diagnostic connector is usually under the hood on driver's side, back near the firewall. Sometimes under the driver's dash. Use a jumper wire and connect terminals TE1 and T1. Then turn key to on, not start, and the check engine light will blink out the trouble codes. If no codes are present, the check engine light will stay on constantly. Remove jumper wire when diagnostics completed. To clear codes after repairs, disconnect the negative battery terminal for one minute, and then reconnect.

2003 Prius sometimes will not start, engine light comes on. Removing key from ignition, reinserting key, & turning wheel till it locks will then allow the car to start. Engine light stays on for a

I had a wire connector on the front of the engine that had so much tension, the wires broke. I didn't notice until a wet day when the car wouldn't start (and the Check Engine light was on). (The error code was related to an Emissions error.) The connector is located on the engine, front, just left of center. Hope this helps!

Over drive light on shifter blinks and check engine light is lit.

You need to have it scanned for codes. The flashing overdrive light means it has trouble codes that pertain to the transmission.

Car want start but turns over

I had the same thing happen to my 2001 Grand Am. Do this.......just key the key, but don't turn it over. Your Security Light should be blinking. Let it blink for about 10 to 15 minutes, it should stay on after that. When it stays on, turn the key and it should start. I still have to do this once every 3 the 4 months, some sort of security problem that cost to much money to fix.

Car cut off when running several times but will not start back up.

O K I'm going to try and explain how to do this. What you need is the codes out of the computer. Here is how you access the codes. Turn the ignition switch on then off then on then off then on again. now leave it on and count how many times the check engine light blinks. Will say the code is 35, what you will see is the light will blink three times then hesitate then blink 5 times and this is 35. you may have more then one code in the computer so watch and count them all and write them all down. Then go to Auto Zone and give them the codes and they will tell you what's wrong. do not start the motor when you are getting the codes.
