Starting problems
I have a 1983 Toyota Camry, the problem is when the temp gets more than 60 outside it will not start, it just turns over and over like there is no gas, only there is. I've checked the fuel pump and replaced the fuel filter. Early in the morning or after 9p.m. it starts and runs perfectly. Anyone have any ideas??

Sounds like a classic main relay problem, where poorly soldered circuit board joints are affected by changes in temperature. Replace it and your problem should be fixed.
You can locate the main relay by turning your ignition key on and off and listening for the click. |

That might be it but they are often located on a metal bracket about where your left knee hits the side panel. I'm more familiar with Hondas but most of the Japanese imports are similar.
See if you can find something that looks like: http://www.partsamerica.com/ProductL...ection%20Relay Call your local Toyota parts department, if necessary, and get the part number for cross-reference purposes. I think the Toyota part no. for the Fuel Injection Main Relay should be 85913-30020. It should look like the Standard Motor Parts #RY291 picture. |

I checked inside the car and found the relay, it wasn't clicking, but then I checked the one under the hood and it was clicking So, I went and bought the new relay and will get it today. I am crossing my fingers that this will solve my problem. I don't understand why it won't work in the warm weather, but works fine when its older out. I will repost and let you know if you solved my issue. Thanks for your help!:D

:) The circuit board, components, and solder have different coefficients of expansion; therefore, they expand and contract at different rates. Over time, poorly soldered connections will fail (cold joints). "Cracks" develop in the solder joints, when it's hot, and "disappear" when it's cold. This results in a relay where current flows properly when it's cold, but not when it warms up. The main relay is normally comprised of two relays, several diodes, and resistors mounted on a small circuit board, which is housed in a small plastic box with a bracket attached to it.
If one has the proper desoldering/soldering equipment, flux, and solder, attempts can be made to repair the cold joints. The cost of a new main relay for your car appears low enough to clearly justify replacing it. Check p. 16 of the following link, which states it should be located under the instrument panel: http://www.autoshop101.com/forms/h8....ain%20relay%22 |

Hi: I am having problems with my '91 Honda civic DX when I drive for a while, then I stop the engine for 5-10 minutes to do some shopping or whatever... and then try to start again. It doesn't start at all. But if I wait another 5 or 10 minutes and I try again, usually starts. I don't have any...
My honda civic dx has a hard time starting sometimes. This only happens occasionally but it'll turn over, but just won't ever start. It happened first about a month ago and is happening once a day now. I replaced the spark plugs and I don't know what else to do.
Hello, my 91 civic hatchback dx suddenly quit while driving--as if it ran out of fuel, and I couldn't get her going again. The usual dash lights work when key turned to position 2 and the fuel pump primes for 2 seconds. The check engine light does not come on. The starter turns the motor over...
This problem started as intermittent but has got much worse, so I now feel lucky when my car starts. When I turn the key, the dash lights come on as normal, there is a noise under the bonnet like a fan whirring, but no spark, so the engine doesn't turn over. I used to just have to turn the key a...
