Hey guys I have a 93 honda civic D15B7 MPFI. I race it on an oval track. Once I do 3 or 4 laps it will not take its gas but it will idle. If I let it idle for a couple seconds then it will go again for another 3 or 4 laps. I changed the dist. the computer, and the fuel pump and it still does the same thing.

Any suggestions would be great

. Did you replace the Ignition Control Module and coil?

. Have you checked the MAP sensor and hoses?

. Have you recently changed the fuel filter?

Here is the whole story... The car is a 92 dx hatch. I took the mpfi intake, wire harnes, computer, dist. map, and fuel pump off a 93 4 door that is when this problem occurred after that I tried a new fuel pump, dist, computer, and I am using a known good mep
