2002 Ford Explorer stock with just over 200k. 4.0 4wd 4dr XLT
relevant items replaced within last year: DPFE sensor, battery, fuel filter, alternator tested and OK. Fuel pressure tested LAST YEAR and was OK at idle. I plan to retest soon.
1) noticed every once in a while for last couple of months, you have to crank a 2nd time to get vehicle started (maybe once a week tops?)
2) One week ago: wife came home to let dogs out and go back out to run errands. gets back in truck after it has been sitting for 20 minutes. crank, no start. cranks, stumbles dies. cranks, starts and idles fine. she turns off and hops in another vehicle just to be safe.
3) i start it 2 hours later, it's fine. drive it to and from work next day, it's fine.
3) i changed spark plugs with autolite platinums. old plugs had about 70k on them, and had normal wear...nothing out of ordinary.
4) we go run errands, truck starts/drives fine. we stop at friends house for 15 min, go to restart and it took about 10-12 tries to get started (each time cranking for 5-8 seconds). on a couple of attempts, it stumbles for a split second, then nothing. After it starts, it idles and drives PERFECT. we then go to mall for 30 minutes, come back out, and it starts fine. we go to THREE more places, and each time it started fine. WEIRD.
5) i drive to work next day, it's fine. i leave work and it cuts off at a stoplight 1 mile from work while sitting in gear. i put in park, it starts fine. i drive home.
6) drove it to work yesterday, no issues.
7) Today, wife starts it to let it warm up for me. i go out 10 minutes later and it had shut off. I try cranking, nothing. So i hop in other vehicle and leave. she attempts to start it 30 minutes later, and can't.
8) I post here looking for help!!!
Fuel pump? IAC? TPS? MAF?
I have a Ecoroute HD for garmin and noticed that the intake air temps from OBDII match the real temperatures outside, +/- 2 degrees. Coolant temp seems to run a little cool, 170-180, so i am going to replace thermostat this weekend. I think that is unrelated, but something that needs to be addressed anyways.
