It has a 5.0L EFI V8 with<br />220,000 (not a Mass Air Flow type engine..those didn't come out until later). The engine runs strong and I take very good care of it. I replaced the timing chain about 50K ago with a heavy duty Edelbrock roller chain. I also replaced the low pressure pump in the tank about 2 years / 24K ago. <br /><br />Tuesday I take the car out and about .5 miles after I left work, it dies. I start it and it<br />runs….for about 2-3 seconds, then sputters and dies. When I prime the fuel system<br />(turn key to on, off, on, off, on, off, etc….then start) it runs a little longer, then sputters<br />and dies. I had to have it towed home.<br /><br />I had a new Fram high pressure fuel filter AND Fram low pressure fuel filter, so I replaced both of them. It did nothing (although the low pressure fuel filter was very dirty for only 30K…and no I never use Arco gas). <br /><br />I used the method of forcing the fuel pump on (ground one of the connectors in the red<br />connector near the battery) and it runs a little longer (about 5-6 seconds) then<br />sputters and dies.<br /><br />I just purchased a fuel pressure gauge and will check the pressure on the fuel rail<br />after work today (Wednesday). I am thinking high pressure fuel pump. It is the original pump. Any ideas?<br /><br />Thanks to those who try to help,<br />BeachTech <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>RiddlerGT</b> <br /><small>Member # 113</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,3,10,9,10,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Sounds to me like a Fuel Pump problem, go get your self a gauge and tell us what its doing <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Marion Cobretti</b> <br /><small>Member # 727</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,3,10,9,31,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I noticed your comment about Arco gas.

You're kidding, right.<br /><br />I have my 5.0L set at 10 before TDC. Of course, it has some miles on it, so I have to use 89 octane or higher to keep it from pinging. If I use 89 octane from Chevron, 76, Mobil, or Shell, no problem. If I use 89 or 91 octane from Arco, it pings like crazy, and runs like crap. And this wasn't just one test at one station. I have tried it several times at several stations, same thing. And whenever I loan my mom my Bronco to pick up something (can't say no to mom) she would makes sure to returned the Bronco to me with a full tank........of Arco gas. Moms, you gotta love them. <img border="0" title="" alt="[Roll Eyes]" src="rolleyes.gif" /><br /> <br /> <small>[ April 10, 2002, 09:52 AM: Message edited by: BeachTech ]</small> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>JohnB</b> <br /><small>Member # 969</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,3,10,10,56,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Don't know if the Bronco's have them, but Mustangs have a fuel pump relay. The relay turns the pump on/off if you have the key in the accessory or on position (so the pump isn't running continously). I had the SAME problem with a 91 5.0 not too long ago. The car would start, then shut off. If I primed it, it would run a lil longer, but not for long. I'd check that. If there is a relay, jump the two power wires, you'll know if it's good or not when you attempt to start it. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
