I know this topic is one thats been extensively covered, but none of the problems others had really fit mine.

The car starts great when its warm out, but when i go to start it in the morning it doesnt start. I have fuel, but no spark. I dont really understand how i can get no spark in the morning but have spark when its warm out...oh yea and the car cranks fine suggesting good battery(i think) and a good starter. The battery is fairly new and freshly charged, so what can the problem be?

Any help appreciated.

No spark? Might want to check and see if you have a bad igniter. Are you sure that you got fuel?

Cpt Ben

no spark, i dont have a factory ignitor as msd replaces that. It is getting fuel, just no spark, and for some reason this only occurs in the morning when its cold out.

so lazy

man this is a tough one... might want to check that MSD out...

Cpt Ben

i thought msd at first as well, then i brought it back to mopac where I bought it, and it bench tested as being in working order..

Cpt Ben

Actually, he said that he did have spark when it was warm outside, and no spark in the morning when it was cold, so again I say check the main relay....good luck

Cpt Ben

the main relay clicks when the key is turned to on position. I only heard it click once if that matters at all.

Cpt Ben

the car started this morning, but only very briefly, it started, then almost immediately died and wouldnt start again.

Cpt Ben

replaced the main relay. Same problem.

so if the car started, you must have had spark....are you absolutely sure you had fuel? now it sounds like fuel pump, or fuel filter....this might sound dumb, but do you have enough gas in the car? you might also check for vapor lock..........just an idea.......I know one of the main techs at Honda and he removed his MSD and went back to stock for some reason....good luck

Cpt Ben

tank is full, i can hear the pump priming. as for vapor lock i cant see how it could get into the lines, as i havent done anything fuel line related in a while. Ill replace the fuel filter and see what happens. MSD is coming out too, just as soon as i find another wiring harness

well not to sound stupid but how cold is it really? if your oil is really thick itll "freeze"up,well at least thats what my redneck automechanic teacher says

Cpt Ben

not that cold...maybe 10 celsius? a summer morning, so not very cold.

Cpt Ben

any ideas?
