The car has 102000 miles and the other day my mom left the inside light on all night and I thought the battery would be dead but it started it took a while thou when I turned the ignition it sounded like it was dead but I kept trying and it started. Today it did the same thing but it clicks kinda like when the starter is bad but feels like its not charging I changed out the starter and still doing the same thing. Any ideas?

Hi jerrymaister,

Check the battery voltage in the morning. The battery could be failing and not retaining sufficient charge when left overnight.

Have the ignitin timing and spark plug related components checked. Could also be a failing ignition coil.

Hard Start When Hot. Plenty of crank seems like not getting fuel. Drops rpm with slight acceleration to maintain speed. (70 mph @ 3,000rpm's, slight acceleration and drops to 2,900rpm then picks up, when it decides, to 3,200 rpm's.)

Items Replaced:
Distributor '05.
Wiring harness, plugs and PCV Valve, Recent.
Timing Belt '05.
Fuel Pump replaced '05.
Fuel Filter last week along with Fuel Injector cleaning.
Fuel Pump checks out okay.
Vacuum checks out okay.
Timing checks out okay.
Ignition checks out okay.

Any clues?
Thanks

I have a 1991 honda and sometimes it doesn't start, when it does this the green "S" light comes on. The owners manual says the light is the sport mode, but it doubles as a service transmission indicator. I have checked the power supply and the starter. When it does it and I can go back within an hour and it starts right up. I have had it in the shop and they ran a diognostic, but could not make the problem occur and found nothing wrong. All they did was give me a full transmission service. I have also checked the fuel pump. What is the problem?

Hi daniel.jourdan,

Thank you for the donation.

The problem is usually caused a faulty PGM-FI main relay. It is known to intermittently cause non starting as the fuel pump is not getting the power to work.

Remove the relay and check the circuit board for cracked soldered joints. Resoldering of the circuit board, especially the cracked joints would make the relay work as well if not better than a replacement part.

I recently replaced my battery and alternator due to my rpms bouncing and my car jerking slightly. That didn't fix the problem so I took it to a shop and they found out my ignition module was cracked and I had that replaced. My car is still running sluggish and my rpms have bounced a few times but not like they used to. Now my car acted like it didn't want to start buy did. On my way to work my car started to shake and then finnaly died. Since then I can start my car but as soon as I put it into drive it will die and it smells like gas and the exhaust is smoking. Other people have said it's a sensor or something computerized or my fuel filter. I don't know what to do. I just need to find out the problem and fix it intead of just guessing what it could be. It is also going through gas fast, but why would my rpms bounce and drive sluggish? I need help fast.

Hi Chelsjess,

I'm not sure which one it was they just refered to it as the ignition module. It looks like it plugs into something and it has a cord on one end that can plug into something else.

Is it a small rectangular and flat piece with a few terminals? If yes then it is the ICM.

The ignitin coil would be a larger black item, almost square with a protruding point.

When rpm jumps, the most common fault is a faulty ignition coil, not the ICM.

So I should have the ignition coil replaced also? And also why would my car die once heated as soon as it's put into drive? I'm having trouble determining on the problem being my o2 sensor or fuel pump. Because when my car is heated and you rev it it smells like gas and white smoke comes from the exhaust. I'm so confused.

A bad ignition coil would fail when it is heated up.

Since it is most likely to be faulty, get it replaced first and test if the stalling still occurs.

Need some advice, I'm the original owner of this 1990 Honda Accord. It has 153,000 on it and when it runs it runs great. Well maintained.

My problem is that it starts hard from time to time. Engine trurns good but just won't start right off. Sounds like fuel or spark? It eventually will start and run great.

I changed the plugs, fuel filter and the igniter was changed several month ago when it just stopped.

I'm trying to develop a pattern to the problem ie, when it happens like fuel level, temp. Etc

Appreciate your help.

Thanks,

Carl Cioppa

Carl

Start with the coolant temperature sensor test it cold and warm normally about 100K ohms cold and drops to 700 ohms when hot and also check the fuel pressure

If the gas is bad, adding some treatment is ok.
