I had to replace the computer on this car about 30 days ago. After replacing computer it ran fine for a few days and now it has become hard to crank. I have discovered that the pump is not priming up on ocassion and I have to keep turning the switch on and off and eventually I will hear it. Then it cranks fine. I have replaced the sensor that controls this to no affect. My mechanic says it must be a bad re-built computer. It may be but I hate to send it back without knowing for sure. Anybody got another idea other than replacing the computer again?
