I have a 2001 Integra GSR fully built and boosted. Lately when i get in the car sometimes the check engine light stays on and it won't start, Sometimes it will start with no check engine light and then all the sudden i hear a relay kick and the check engine light comes on and the car will not rev past 3k and it dies. It has also been doing this while driving sometime it kicks on and off really fast and then its fine other times i have to shut the car off and it goes away sometimes it take 3 or 4 cycles of the key before it works right.

Is it common for the relays for the fuel pump to crap out?

 

the solder on the main relay cracks over time due to the high voltage, cracks are really small sometimes, but can still interrupt power to the fuel pump.
