Test fuel pressure and check gas tank vent lines from the tank to the charcol canister. Remove the gas cap and listen for a suction sound indicating plugged vent lines. You can use an aircompressor to blow the dirt out of the lines. Your car is old and it might have leaking fuel lines causing the vapour lock like symptoms.

Cool down the cabin temperature (open all doors and windows etc), and if it starts once it's cooled down, it's probably the main relay assembly. I had mine replaced at Honda a few years ago for about $200 cdn.

You will need to explain all that at a repair shop,
so they can duplicate the issue & then do some
testing, to find & resolve the problem
No one can tell you over the internet on a guess
Always need the car to find any problems

I have a 2002 buick lesabre and the water pump was changes about a month ago. The car ran fine. The last week, the car is temp gauge is reading hot very fast. I dont smell any coolant and it doenst sm

some times when the water pump is changed you gotta fill up the radiator with coolant, run the engine until it gets hot, shut off the car and wait until the car cools down to put more coolant because some air may stay trapped inside and by following this steps you get rid of the air trapped inside.
try this:
1) when the car is cool take the cap of the radiator off and see if it's full. if it isn't, with the car still off, put some coolant until it gets full.

2) once the radiator is full, start your car and wait to see if the coolant goes down the radiator. if it does, keep putting coolant until it doesn't take any more.

Hope to be useful.

1996 Chevy k1500 will not turn over after setting in the hot sun

check the starter relay contacts and the electrical portion of the ignition switch. the heat can expand a solder point just enough to create an open circuit.

Hi im having start up issues with my honda cr-v 2002- rd5 series. I would drive for some time and when i stop and return the vehicle would not start, i have to wait atleast 30 min before i start. Though...

If the occasional fail to start increases more often with temperature, that is outside temp or inside temp if the car is sitting in the sun, the saturday morning "cartalk" guys on NPR repeatedly say that Honda has a problem with a fuel pump relay which sits up under the dash. It goes bad and this generally happens with a hot day or a hot interior. So maybe you want to give that a shot.

I have a 94 mustang with an electric fan. The fan works perfectly when i start the car and its cold. when the temp of the water gets up to about 185 the fan kicks on . it can idle all day and the fan works...

is the car running hot? some cooling fans never come on going down the road because the air comjng through the front of the vehicle keeps the car cool enough that it doesn't need to come on. but if it is overheating then you may want to check the cooling fan relay.

Engine Overheats when AC is on..

It sounds like your AC compressor bearings may be overheating causing excessive drag/loading on the engine. No easy way to check this unless you can take the serpentine belt off when the car won't start and see if it is really hard to turn the compressor shaft.

Engine starves for fuel after running about 50 miles or so...

Has Neon do same, I ran fuel at low level, on hot day, ran engine until it started to act up & threw a fuel pressure gauge on it. Was at approx 5 psi. Cold next morning, 48-50 psi. Always hot day about 30-40 miles into work in morning, o.k. Sit in hot sun all day & would happen 3-4 times on way home. Sit and let cool, 20 minutes or so & go again for a while. Cool day, no problem. Change pump I would.

When the inside of the car gets hot from the sun it will not start. What I get is service column lock. Wait for the sun to go down open the windows and door wait for the inside to cool down and she will...

Because this communicates on RF, I would suspect that there is loss of signal when overheated. I also am in AZ and see CAN buss and RF go down in heat. This time of year you should be able to leave it @ shop to recreate problem and then check for buss. After alll, it was 107 here ysterday.

Dome light stays on when it is very hot outside and during a sunny day. The door ajar light on instrument panel lights up also. Both stay lit until it cools down or the sun goes down.

you have a short circuit somewhere in your dash cluster, when it heats up the wires probably soften and droop down contacting another wire and closing one or more lamp circuits. If you feel like taking the dash apart, get a wire location diagram and find the short, or take it to an automotive electrical shop.
