91 Accord Ex..vehicle sat for 6 years without being run. 6 years ago the timing belt, water pump, spark plug tube seals all were replaced. Last week replaced fuel pump, fuel filter, spark plugs and wires, distrubutor cap and rotor, coil, main relay, starter and alternator. Vehicle fired right up and ran great. The last 2 days I've had an issue where the motor turns over, however, will not fire. There is spark while this occurring. It feels different though from when it turns over normally. Almost as if there is no compression. If you start and stop trying to to start it multiple times it will start and run extremely rough for a few seconds and blows some white smoke from exhaust. Then it will run normally. This usually occurs when the motor is cold. Although it has started right up from being cold. Any thoughts would be great a help. Thanks

 

I would try cleaning the IACV, the FITV, and the throttle body. Reset the ECU. Check base timing and ignition timing. You said you have sparks, is it at the wires and the dizzy?

 

Thanks for the response. I appreciate it. Not sure what dizzy means, however, spark was tested with the plug out and grounded. I will clean what you mentioned and let you know what happens. Thanks again

 

Yeah, what does "dizzy" mean? I'll guess it means distributor.

 

yes it does mean distributor, no offense to the person that used the term, but i hate when people call a distributor a dizzy

i had an 89 accord, that was really hard to get started after it had been driven and was warmed up, but when was cold, started right up,

turns out, the coolant temp sensor was bad, making the engine think it was always cold, so when it was actually hot, and trying to start, it was getting too much fuel,

i think it could also be bad , by telling your computer its hot, when its actually cold

note: some cars have more than one coolant temp sensor

 

Could be the ECT sensor located under the distributor. You can test it by warming the car completely up and then disconnecting the connector. It's the two-prong connector. The one-prong one next to it is the temperature sender. Test for resistance on the 2k setting. It should be around 180 - 400 ohms.
