ok, problems, my car will crank over fine, but it will not start till the check engine lights goes off and the main relay kicks on, when it kicks on the check engine light goes off, up till this morning it always started, now, the check engine light wont go off, and the main relay wont kick on, any ideas on this subject.... need help A.S.A.P!!!!

 

Ok here's an update, my car finally started, but the new main relay still takes forever to kick on and the fuel pump to kick on, once they kick on it starts, but I can drive it somewhere, then shut it off and come back ten minutes later, I still have to wait a few for it to kick on, windows down and all so it don't get hot, and even that it happened this evening when it was cool out... Any suggestions?

 

someone please help!!!! ive looked thru all the forums and none of the problems match mine, the main relay is good, and the ignition switch is good, any ideas on where to look thru the wires at to find a short???? please please please help!!!!

 

Check the "inputs" to the relay.

 

ok i just checked those, they are all good... any other ideaas?

 

What do you mean when you say the main relay takes a long time to kick on? How can you verify that it's the main relay which is the delay?

 

beacause the main relay/ fuel pump relay are pretty well the same thing, i can hear it kick on right before the check engine light goes off, and if i put my hand on it, i can feel it kick... then i hear the fuel pump as soon as i hear it kick on....

 

So when you say you've checked the inputs, how did you do this? Did you put a test light on the main relay inputs when it's being delayed? If so, were you getting power supplied to the relay at the time of delay or not? If not, check the ignition switch. If so, suspect faulty relay.

 

i used the volt meter and check the voltage on the inputs of the plug to the main relay, with they key off and the key on, and when the main relay kicked on, when it kicked on and with the key being on, none of the voltage changed, but ive went threw three main relays, and i know i didnt get 3 bad ones.. and i still have the problem whether it be hot or cold, is still takes a few minutes to kick on....

 

but one other thing, what do i look up car wise for the motor thats in the car being an F20B? cause thats one problem i have ran into, on looking up parts....

 

Look up H22A.

 

now, which car did that motor come in? and would the main relay on it be the same and should i run it?

 

ive checked all my gounds and most of the wires, and fuel pump, im runnning out of ideas, does anyone have any other suggestions before i kill myself for takeing it to a honda dealership and paying hundreds of dollars? could it be my ecu? if so, what ecu should i look for to put in it to try?

 

ok, one other question, how bout the ecu? if it is bad would it do that? if so, what ecu should i try? not sure whats in it right now either... all the labels are peeled off and its chipped on chrome....
