1991 v6 camry noobie, please help!!! No start so spark!!!

[cloudstrife930]

I have a 1991 toyota camry v6. It wont turn over. I was getting no spark, I replaced the distributor and still getting no spark. I dont have 12 volts at he distributor either. Is my ignitor bad or coil. It was originall idleing funny and I took a spark plug wire out to check for spark then it just shut off, never started after. Any advice would be greatly appreciated.

OK, terminology... when you turn the key it sounds as if the engine turns over but does not start. Is this correct? "turn over" and "crank" mean the same thing. "start" and "run" are pretty much the same thing.

Take the distributor cap off and see if the rotor turns while someone cranks the engine. If it doesn't, the timing belt is probably broken.

When you turn the key to the on position, all of the dash indicator lights come on in a test mode. Does the Check Engine Light come on? If not, check your EFI relay and EFI fuse.

You said that you weren't getting 12 volts to the distributor. Do you have 12 volts at the battery? I can't see why you wouldn't have whatever the supply voltage was. You may need to charge up the battery or maybe you have a loose or corroded supply wire.

The air hose to the throttle body is attached at both ends, right?

yeah the car cranks but no start. i have no spark, and by the way thankyou for the reply. I took the cap off and the distributor turns while the engine is cranking. I dont get why I dont have 12 volts at the distriburtor with the key on.I checked all 4 wires with a test light that go to the distributor, and it lights up for none of the wires. Distributor is moving tho and the timing belt isnt broken. Just no spark at all. Changed the distributor and noithing. I checked the efi fuse, but not the relay tho. Should I try jumpinig the relay and see what happens? All the lights do come up for tho in test mode. Does the ignitor send send 12 volts to the distributor? All your input is appreciated. Thankyou. Fuel, no spark! No voltage at the distributor!!! Thanks again.

Check connectors between the igniter, coil and distributor. There should be 12V at the plus side of the coil. If OK check the coil resistance, should be 0.41-0.5 ohm primary, 10.2-13.8 secondary.

^+1 on toyomoho's suggestions.

I take it that you have 12v at the battery.

If the CEL comes on during the POST when you turn the key the EFI relay (and fuse) are likely OK.

There are some other checks if these don't pan out. The computer may be getting some signals that make it switch off. The ignition switch may have a problem. And probably more..

If you do a search on "won't start" I expect that you will find a lot of posts that may give you additional insight.

Keep us posted
