Hey everybody, we've got a weird problem (weird to us at least) we've got a B18 in a crx, and it will start with computers for DPFI cars, but not any MPFI car's computer. We have rewired the car several different times, the way it was wired when he bought the car, the kid that he got it from said was 'the right way' but we completely rewired it with an SI's wiring harnesses (under dash and engine harnesses) We can start it with the DPFI computers and it lopes like a top fueler, sounds wicked yes, but doesn't run well at all. We have tried several computers that will start a 1990 integra no problem, and they turn over but will not fire. one is from an integra, one is from a CRX si, and one is from a hatch SI. The motor ran in the integra that it was pulled from. Any ideas would be greatly appreciated!
