DaveFromColorado Posted March 23, 2004 Report Posted March 23, 2004 I had this same problem on my 91 Beretta, I found that mine was caused by the oil pressure switch, it stays active even after the oil pressure is lost, you have to replace it, it's fairly cheap, less then $30 I think, it makes it a LOT easier to pull the starter when replacing that part.

Slade901 Posted March 23, 2004 Report Posted March 23, 2004 There is a fuel pump relay near the remote positive terminal post. If you got two cooling fans for the radiator, try removing the 2nd fan relay and use that for the fuel pump temporarily and see if the issue is resolved. If it does then just purchase a new relay and put back the relay for the 2nd fan. If that does not work, try what DaveFromColorado said about replacing the oil pressure switch. Quote
