Hi,

My Acura has been overheating some and having problems starting in hot weather. It was not an every day thing, but when it would not start it would usually start up after cooling for a few minutes, or it would have a rough start and you would have to give it some gas or put it into drive ore reverse quickly to keep the car from dieing.

After some research I thought it may be the main relay. The car was starting up fine at that point, I decided to try and resoder the main relay, then when I reattached it the car would not start at all. It still cranks just wont start. I then bought a new main relay and it behaves the same. it will crank, but still not start.

I am not sure what I could have done to make it not start at all no by replacing the main relay, I am guessing the problem may be with the fuel pump or the fuel pump regulator, but I am not really sure.

Any help or ideas would be great. Thanks.

 

Download the factory service manual for troubleshooting.
Check all the interlocks, switches, relays, wiring connections, etc....and so on. "PIA"
Gotta try to narrow it down to either electrical or fuel related. Have the fuel pressure checked, may be a leaky injector, IDK ??? Try searching the site for related threads.
