I have a 92 Civic DX with a 98 GSR swap in it. I also have the GSR fuel pump as well. Every once in awhile, when it's a VERY hot day out (close to 95-100) the fuel pump won't kick on to start the car. I'll click the key to acc. and wait for the pump to kick on and build pressure before I start it... but it never kicks on. Then if I go ahead and try and start it... it'll just die immediately. I'll usually let it sit for about 30 sec. or so, then it's all ok... kicks on and starts up. This only seems to happen on those REALLY hot days... where is the best place to start looking? Is this a typical symptom of a fuel pump going bad? Any help would be greatly appreciated.

Thanks,
Brad

 

I would check any wiring that relates to the fuel pump, including voltage of the wiring while on.

 

Do you happen to know what the voltage should be? Thanks for the response.
