'99 Morning "No Start" issue....

Replaced entire fuel sender unit in January for "no start" issue and then rebuilt unit in June for same problem. Now, I am having same issue - the van won't start without some ether in the morning (temp.in 70's) but then will start okay without ether for the rest of the day. But, let it sit overnight and it won't start on its on in the morning. I have connected a fuel pressure gauge and have been checking the readings through out the day. In the morning, the fuel pressure will not get above 55 lbs. while at other times during the day, the pressure is 58 - 60 lbs. Also, in the morning, the pressure seems to drop rapidly (55 down to 50 in a minute or so), but does not drop for the rest of the day. It seems like starting the engine once will make it okay for 24 hours and then you have to repeat the ether process to get it going again. Any thoughts or suggestions?

:confused:

Hi friendlyphotog

From what you posted, your well within specs for fuel pressure. When was the last tune-up done to your vehicle? Thanks.:)
Hi friendlyphotog

Great advice given so far. If what was already suggested doesn't help your no start condition, then my next thought would be a weak spark from the coil. Maybe have a look at that and let us know what you find, thanks.:)
