Hey guys, I'm in a bit of a problem. I have a 90 Acura Integra with a B16A1. Everything works great and no problems, except for the fact that sometimes my car turns over but wont start. I opened my gas filler cap and put the key on the on position and didn't hear the fuel pump turn on (outside temperature being about 95 degrees. sacramento). After many failed attempts, I went finally after 8 hours and started it (now being around 70 degrees) and it fires up. The mileage on the car is almost near the 160,000 mark. From my knowlegde, the fuel pump has never been changed. I also heard of an MFR (Main Fuel Relay) from anyone's experience, what may my problem be?

 

hey kidd,

its ur main relay, in this hot *** weather the relay will overheat and car won't start until it cools down.

so change the relay. go pick and pull and jack one or buy a new one

 

Hey Thanks bro. Thats what I thought it was too.

 

take it out and re solder the connections, then it's free
