ALSO this happends in cycles like every 50 start ups or so?? thank you for thanking your time and trying to help me

 

check the pgm-fi sensor by the main relay under the dash..

prime the fuel pump like 5-6 times before starting when it gives you the problem,if it helps,your fuel pump is probably weakening..

 

hey buddy lol i just posted on yours lol 2 people 2 problems thank doing some reasearch right now about relay 2

 

thanks and i appreciate that!take your relay out and open it up.look around at the solder points and if there are little rings in the solder,then the relay has suffered from overheating and will continue to give problems as the temperature in the car changes..

 

when the problem happens i dont hear the 2nd click if that helps ....but it does end up starting??

 

also,you can try smacking the main relay a little when it doesnt want to start.

 

well, dont know about honda ignition switches but have had that problem with an s-10. all functions and lights came on truck turned over no pump, sometimes. replaced switch and it never did it again.

 

The PGM-FI Main Relay is a common problem on older Honda/Acura but almost always an easy fix... http://www.tegger.com/hondafaq/mainrelay.html I have done this repair on 20+ Honda/Acura, including my 94

It is harder and takes longer to get the PGM-FI Main Relay out of the car, [easier on a G2 then a G3] then it is to fix it.

JuicedUpRice what the hell is a "pgm-fi sensor"??? 94

 

sorry, i knew that wasnt what it was called lol
