Ok so my car randomly dies then I wait a little bit like 20min and it will start right up does this sound like fuel pump problem or main relay or what I hear the fuel pump priming now and its starts up fine but when it dies the I dont hear the fuel pump does the fuel pump randomly die and then come back on if its going out or is there a short in a wire or somthing......
any help will be appreciated
also im throwing a code for o2 sensor would that have anything to do with it?

check o2 sensor see how bad it looks, and what motor are you running w/ what ecu/ fuel pump???

id put money on the main relay!

im putting money on the relay as well although the o2 code could be a too lean condition caused by the pump. but ive RARELY seen a honda pump go out. they are durable little bastards
+1 for main relay

Mr_Moos

pretty sure its main relay it wouldnt start so i took the relay off and jumped the yel/blk wire and some other one and the fuel pump primed doesnt that mean its a bad relay?

yea the relay basically uses a small amount of current to energize a switch that control a large amount of current. relay buddy
