OK guys I have a problem with my car not starting. It happens every once and a while and the only way to get it going it to dump a bit of gas down the throtle body.
Now did the fuel pump 5 months ago and once i have the car going it will run for a month or a week. This morning it tripped a code (Ignition/Distributor engine speed input circuit malfunction). Any help would be great.

Thanks Brad
