Happy Holidays ALL,
Newbie-My 2nd visit here:
I HAVE A 1999 EXPRESS v-6-4.3L- Cargo van- 125,000 mi on it-- 3 weeks ago she would crank but not start- later in the day it started right up as soon as I turned the key- I suspected a bad fuel pump because it sounded like no fuel and since high mileage and the pump didn't cycle on- OK got a new pump- emptied most of the tank(-it was full-)drove it over to mechanic & had it installed by mechanic-Old pump was in bad shape- installed a New OEM pump by the way- worked great started right up -ran even smoother-no problems at all since new installation--3 wks passed now-- yesterday Sunday I get in van to start it--engine cranked but wouldn't turn over .Sounded just like it did before I put new pump in-- I was in my driveway yard-So I called Triple A- just to see - he cked out Battery (from 2010)- Battery was still great- He went underneath van and told me to start it- all it would do was crank and not start- He said -"it sounds like it could be a fuel issue or a poor spark"-and i smell gas fumes-- That's all he could do but offer me a tow to a repair station- I belayed that and sent him on his way. I just filled the tank on Sat at my usual station-did errands, the day before- no problems -van runs great-All day Sun Van doesn't start up-- Today-Monday I get in van and it starts right up on first turn of the Key!- as a matter of fact I started it 2 more times and moved it around the yard- not to take a chance of getting stuck someplace I used my other car- Tune up was done in 2012 at 100,000--new starter 2011-- so any suggestions of what to check/diagnose by the numbers- I have a OBD II- I'm handy-before I take it to a station before spending more bucks this Holiday Season
Thanks -99expressman

@jjrbus why are you hijacking somebody's 9 year old question about ignition in the "New Member Welcome Area"? Please go to the van section and start a new thread. Thanks.
