It seems like there is a rash of these fuel pressure regulators going bad. The '84 I just got had this exact problem. It would start initially, but then when it warmed up and you tried to restart it wouldn't. The guy I bought it from rigged up a switch to the fuel pump. He would shut off the pump when trying to restart and the van would start and then he would switch the pump on and it would run. So it seems pretty obvious that what was going on was that the fuel pressure was too high and basically flooding the motor when you tried to restart. The other folks that were having this problem last week actually got so much fuel in the cylinder that it caused a hydraulic lock (yikes!). One thing that amazes me is that the fuel injectors are allowing the over pressurized fuel to leak past them and into the motor. I thought that when these injectors were shut they wouldn't allow any fuel past them? Or maybe they aren't leaking past but just dumping a bunch of fuel when they do open due to the higher pressure? Any one have any ideas on this? Thanks, Ken Wilford http://www.vanagain.com John 3:16 Office (856)-765-1583 Shop (856)-327-0027 Fax (856)-327-2242 |
